I am trying to append rows to a table using an array called searchResults. Everything works as expected until I introduce the jQuery UI dialog box. The problem is I need a new dialog box for each row in the first column. I'm pretty new to all of this so I'm pretty sure I'm using the index incorrectly at times. This is just to give you an idea of what I'm trying to accomplish. Any ideas how to do this correctly?
for (var i = 0; i < searchResults.length; i++)
{
$('#patientFileDialog[i]').dialog();
$'#openPFDialog[i]').click(function() {
$('#patientFileDialog[i]').dialog('open');
});
var dialog[i] = $(`<div id="patientFileDialog[i]" title="Patient File">${searchResults[i].patientWebLink}</div>`);
body.append('<tr>'+
`<td><button id="openPFDialog[i]">Click Here</button></td>` +
`<td>${searchResults[i].patientFirstName}</td>` +
`<td>${searchResults[i].patientLastName}</td>` +
`<td>${searchResults[i].patientDateOfBirth}</td>` +
`<td>${searchResults[i].patientDataPulseID}</td>` +
`<td>${searchResults[i].patientLaserFicheID}</td>` +
'</tr>')
}
After looking at your code a bit more I think I can see what you are trying to do. Working JSFiddle, with some faked searchResults so we can see it in action.
There are a few problems with the code in your question:
Using selectors like $('#patientFileDialog[i]') and $'#openPFDialog[i]') will try to match elements on the page with those IDs. AFAICT those don't actually exist yet, you are trying to create them.
var dialog[i] = ... sets up some divs as strings, but those are never added to the page;
As I mentioned in my comment, there are some syntax errors, maybe just typos and mixed up formatting here on SO;
Here's an updated version of the code. Notable changes:
Instead of adding an event handler for every individual openPFDialog button, it is better practice to add just one which matches them all. That single handler can then work out which button was clicked, and take the right action for just that one, not all of them. In this case if you have all your buttons use IDs that match openPFDialog-X, where X is a number, you can target anything matching that pattern (using a starts with selector, and find the X by removing the openPFDialog- part with replace.
There's an added complication with the above though. Selectors parsed at page load will only match elements that exist at that time. In this case, you're adding new elements to the page, and a selector defined at page load won't match them. The solution is to select instead some parent element which does exist at page load, and filter. This is called event delegation (search for the paragraph starting with "Delegated event handlers").
Working from what you have, I am guessing the patientFileDialogs you create should be placed inside some parent element which is not displayed on the page? That's what I've done.
Here's the code (and working JSFiddle):
var dialog, i;
// Single click handler for anything that starts with "openPFDialog-".
// Since those elements don't exist on the page yet, we need to instead
// select a parent object, say the body, and filter for clicks on our
// elements starting with our pattern
$('body').on('click', '[id^=openPFDialog]', function() {
// We need to find the "i"
i = $(this).attr('id').replace(/openPFDialog-/,'');
console.log('clicked on id', i);
$('#patientFileDialog-' + i).dialog();
});
for (var i = 0; i < searchResults.length; i++) {
// Create a new div with ID like "patientFileDialog-1", using the current
// search result
dialog = $('<div id="patientFileDialog-' + i + '" title="Patient File">' + searchResults[i].patientWebLink + '</div>');
// Add it to the page. I've use a div with ID dialogs which is hidden
$('#dialogs').append(dialog);
$('table').append('<tr>'+
'<td><button id="openPFDialog-' + i + '">Click Here</button></td>' +
'<td>' + searchResults[i].patientFirstName + '</td>' +
'<td>' + searchResults[i].patientLastName + '</td>' +
'<td>' + searchResults[i].patientDateOfBirth + '</td>' +
'<td>' + searchResults[i].patientDataPulseID + '</td>' +
'<td>' + searchResults[i].patientLaserFicheID + '</td>' +
'</tr>');
}
Update
One last suggestion - manipulating the DOM by adding/removing elements is slow. If you need to do that for each element in an array, it is best to avoid actually adding your content on each iteration, and rather just build up a string. Then once you're done iterating, just add the big single string, so you're chaning the DOM just once. Here's the basic changes needed to do that:
// Add some new variables to hold our big strings
var dialog, dialogs, row, rows, i;
// ... your code ...
for (var i = 0; i < searchResults.length; i++) {
// Create the dialog ...
dialog = ...
// Append it to our big string of all dialogs
dialogs += dialog;
// Same approach for rows
row = '<tr>'+ ... all that stuff
rows += row;
}
// Finished iterating, nothing added to DOM yet. Do it all at once::
$('#dialogs').append(dialogs);
$('table').append(rows);
Here is what I finally ended up having to do:
$(document).ready(function(){
if ($('[attr="searchResultsJson"]').length)
{
$('.approval-outer-wrap').prepend(drawTable());
$('.approval-outer-wrap').append('<div id="result-details" title="Search Result Detail"><p></p></div>')
}
$('body').on('click', '[id^=openPFDialog]', function() {
var result = $(this).parents('tr').data('result');
$('#result-details p').html(result.patientFirstName);
$('#result-details').dialog();
});
});
function drawTable(){
var table = $('<table id="search-results" />');
var header = $('<thead />');
table.append(header);
header.append('<tr><th>Patient File</th><th>First Name</th><th>Last Name</th><th>Date of Birth</th><th>Data Pulse ID</th><th>Laserfiche ID</th></tr>');
var body = $('<tbody />');
table.append(body);
var json = $('[attr="searchResultsJson"] [type="text"]').text();
var searchResults = JSON.parse(json);
for (var i = 0; i < searchResults.length; i++) {
body.append(`<tr data-result='${JSON.stringify(searchResults[i])}'>`+
`<td><button id="openPFDialog-` + i + `">🔍</button></td>` +
`<td>${searchResults[i].patientFirstName}</td>` +
`<td>${searchResults[i].patientLastName}</td>` +
`<td>${searchResults[i].patientDateOfBirth}</td>` +
`<td>${searchResults[i].patientDataPulseID}</td>` +
`<td>${searchResults[i].patientLaserFicheID}</td>` +
'</tr>');
}
return table;
}
Consider the following code.
function showPatientDialog(cnt){
$("#patient-file-dialog").html(cnt).dialog("open");
}
var d = $("<div>", {
id: "patient-file-dialog",
title: "Patient File"
})
.appendTo("body")
.dialog({
autoOpen: false
});
$.each(searchResults, function(i, result) {
var row = $("<tr>").appendTo(body);
$("<td>").appendTo(row).html($("<button>", {
id: "open-pdf-dialog-" + i
}).click(function() {
showPatientDialog(result.patientWebLink);
}));
$("<td>").appendTo(row).html(result.patientFirstName);
$("<td>").appendTo(row).html(result.patientLastName);
$("<td>").appendTo(row).html(result.patientDateOfBirth);
$("<td>").appendTo(row).html(result.patientDataPulseID);
$("<td>").appendTo(row).html(result.patientLaserFicheID);
});

I have a Ruby on Rails project where I use a DHTMLX Grid.
Is there a way of showing, using the event handler "onFullSync" provided by the grid API, to show updated data?
Let me explain a little better... I know I can do something like:
dp.attachEvent("onFullSync", function(){
alert("update complete");
})
But what I want is something more complex. I want to, after each completed update, alter a div adding the information like this:
Field 2 was updated to XYZ and field 3 was updated to XER on line X
Field 1 was updated to 123 and field 3 was updated to XSD on line Y
Is this possible?
Thanks
There is a onAfterUpdate event that can be used similar to onFullSync
http://docs.dhtmlx.com/api__dataprocessor_onafterupdate_event.html
It will fire after each data saving operation ( if you are saving 5 rows - it will fire 5 times )
Still, info about updated columns will not be available here.
Also, you can try onEditCell event of grid. It fires after changing data in db, but before real saving in database. Here you can get all necessary info - row, column, old value and new value.
http://docs.dhtmlx.com/api__link__dhtmlxtreegrid_oneditcell_event.html
So, what I end up doing was:
After creating the grid I created an array:
var samples = [];
Then, as per #Aquatic suggestion, I added to "onEditCell" event the following line:
samples[samples.length] = grid.cells(rId, 5).getValue();
This allowed me to add to the array the value present on column 5 of the row changed. Then, on "onFullSync" event I hide or show the div created on the view with the messages (I distinguish if it's on row or more changed on the grid).
//Deals with messages after update
dp.attachEvent("onFullSync", function(){
unique_samples = uniq_fast(samples.sort());
if (unique_samples.length == 1){
$('#updated-samples').text("");
$(".messages").show();
$('#updated-samples').text("A seguinte amostra foi actualizada: " + unique_samples[0]);
//to clear the array
samples = [];
} else if (unique_samples.length > 1){
$('#updated-samples').text("");
$(".messages").show();
$('#updated-samples').text("As seguintes amostras foram actualizadas: " + unique_samples.sort().join(", "));
//to clear the array
samples = [];
} else {
$('#updated-samples').text("");
$(".messages").hide();
//to clear the array
samples = [];
}
})
The problem with using "onEditCell" is that everytime a field is changed on that row I get a repeated value on my "samples" array, I I had to remove duplicate from that array. For that I used one of the suggestions at this answer
// remove duplicates in array
function uniq_fast(a) {
var seen = {};
var out = [];
var len = a.length;
var j = 0;
for(var i = 0; i < len; i++) {
var item = a[i];
if(seen[item] !== 1) {
seen[item] = 1;
out[j++] = item;
}
}
return out;
}
Then I have on the beginning of the view, to show the messages:
<div class="alert alert-success messages" id="updated-samples">
And that's it. I could be not the most efficient way but it works for what I wanted. I will leave the question open a few more days to see if any other option appears.
Is there a more efficient way for displaying a tool tip once a cell is hovered? Using the structure attribute to format the datagrid, is there a way to use formatter to display a dijit toolTip rather than using the html title attribute.
Here is the column in which the toolTip is displaying.
var subscriberGridLayout = [
{
name: " ",
field: "ExpirationDate",
formatter: function(value){
if(value){
expDate = formatDateIE(value);
return toolTip();
}
else
return " ";
},
styles: "text-align: center;",
width: "30px"
},
Here is the function that displays a tooltip icon through the image tag but instead of a dijit toolTip it simply uses html's title to display a popup.
function toolTip(){
src = "'/Subscriber/resources/images/icons/icon_error.gif'/>";
if(dojo.date.difference(today, expDate) <= 0 ){
message = "Credential expired.";
return "<img title='"+ message + "' src=" + src + "";
} else if(dojo.date.difference(today, expDate) <= 60) {
message = "This Subscriber will expire in " + dojo.date.difference(today, expDate) + " days."
+ "
To prevent an interruption in the Subscriber’s access, please sumbit a request to " +
"renew the Subscriber within 30 days of the expiration date.";
return "<img title='"+ message + "' src=" + src + "";
} else {
return " ";
}
}
I would do something like:
new Tooltip({
connectId: grid.domNode,
selector: "td",
getContent: function(matchedNode){
return matchedNode.innerText
}
});
With grid.domNode you can get the generated DOM of your widget. A grid generates a table-structure, so you can get the cells by using the selector and getContent properties.
I must say it's not really the correct way to do it because now you're playing with the internal structure of the Dojo widget. If they once decide not to use a table as DOM structure your code won't work.
But I don't think there is a better way to achieve this, in the end you will always have to translate the Dojo cell to a DOM node (because tooltips are DOM based). You can of course connect a tooltip to each cell, but I tried that before and it was a little buggy (sometimes the tooltip didn't pop up).
I also made a JSFiddle to show you a working example.
When i try to make these dynamically made textareas into CEditor fields i get the error:
TypeError: b is undefined
my code:
var input = $("<textarea>").addClass("textAreaClassTest");
//input.setAttribute("id", "como");
//input.setIdAttribute("id", "como");
//input.ID = 'como';
CKEDITOR.replace('como');
item.append(input);
//CKEDITOR.replace('como');
return item;
i cant seem to give the textarea an id - any id's :)
I'm assuming you're using jQuery and only working with 1 or more text areas at a time. So you can get the text areas and assign them ids and use them as below.
//select all text areas
var input = $("textarea");
var list = new Array();
var count = 0;
input.each(function () {
count++;
$this = $(this);
$this.attr("id", "como" + count);
console.log('id is "' + $this.attr("id") + '" and text is "' + $this.text() + '"');
CKEDITOR.replace($this.attr("id"));
list.push($this.attr("id"));
});
//return the list of replaced text area ids
return list;
I have a JQM page that is inserted dynamically into the DOM and must be regenerated every time, as the data may change. The first time the page is displayed, everything works as it should, but if the user returns to this page later, I have the following rendering problem. Here is the list closed:
Here is the list open on the second viewing of the screen:
I've tried various combinations of $(id-selector).trigger('create'), .remove(), and .empty(), but nothing so far makes the page the second time work like it does on the first.
For what it's worth, since this seems to be a problem with JQM for which I am seeking a workaround, here's the code that builds this list:
var url_base_key = resource.url + '_base';
html += '<div data-role="collapsible-set" data-inset="false" id="per-back-issues">';
if (window.per_info.back_issues.length > 0){
html += '<br /><p><b>' + Label('label_back_issues') + '</b></p>';
for (var i = 0; i < window.per_info.back_issues.length; i++){
var group = window.per_info.back_issues[i];
if (group.issues.length > 0){
html += '<div data-role="collapsible" class="per_group" id="per-group-' + group.group + '"><h2 id="group-label-' + group.group + '">' + group.group + '</h2><ul data-role="listview">';
for(var j = 0; j < group.issues.length; j++){
var issue = group.issues[j];
var url_base = window.orgbase_api[url_base_key];
var url = url_base + issue.formats[0].file;
var id = resource.orgbaseapi_url + '-' + issue.year + '-' + issue.month + '-lit_menu_item';
var item = '<li class="per_item">' + GetPdfLink(resource.id, id, url, GetLongMonth('gregorian', issue.month)) + '</li>'
html += item;
}
html += '</ul></div>';
}
}
}
html += '</div>';
This content is wrapped in a JQM page container
<div id="newsletter" data-role="page" data-theme="b" data-content-theme="b">
<div data-role="header">
Back
<h1>Newsletter</h1>
Home
</div>
...
</div>
and added to the DOM every time with
var new_screen = $(html);
new_screen.appendTo($.mobile.pageContainer);
If I try to do a $('#newsletter').remove() before the appendTo(), the appendTo() doesn't work. I can't use an expand event to force the list to redraw itself because the event fires before the expansion happens.
Ok, the problem seems to be the use of new_screen.appendTo($.mobile.pageContainer) multiple times for the same id. I had tried to remove it using $('#' + id).empty().remove() if it already exists before the appendTo(), but I couldn't add it again (perhaps someone can help me understand why I can't do it this way). So I tried just updating the container if it already exists and that fixed the problem. I'd like to understand how adding the item multiple times led to the results I got.
if ($('#' + id).length > 0){
var html = script + body;
//update existing page container
$(id).html(html);
} else {
var html = '<div id="' + id + '" data-role="page" data-url="' + id
+ '" data-theme="' + theme + '" data-content-theme="' + theme + '" class="screen_section">'
+ script + body + '</div>';
var new_screen = $(html);
//add new page container to DOM
new_screen.appendTo($.mobile.pageContainer);
}
I am creating a JQuery Mobile application that has a listview. I am populating that listview with the results of a web service. Because of this, the items in the list view are being populated as shown here:
$.each(results, function (i, result) {
var s = "<li><h2 style='padding-left:40px;'>" + result.title + "</h2><p style='padding-left:40px;'>";
s += result.subTitle;
s += "</p><span class='ul-li-count'>" + result.count + "</span></li>";
$("#resultListView").append(s);
});
$("#resultListView").listview("refresh");
My listview is being populated correctly. The value for the count bubble is showing. However, the UI does not render the bubble. Is there a way to dynamically build a result set with count bubbles in a list view? If so, how?
Thank you!
Your way should work. The only thing I can think of is that the HTML is not valid.
Anyway, I created a simple version to show that it's possible. http://jsfiddle.net/kiliman/HDUqp/
Basically, just build up the HTML for <li/> and append to the list, then call .listview('refresh')
$('#page1').bind('pageinit', function(e, data) {
var n = 0;
$('#addResult').click(function(e) {
var $list = $('#resultListView');
n++;
$('<li/>')
.append($('<h2>', { text: 'Title ' + n }))
.append($('<p>', { text: 'SubTitle ' + n }))
.append($('<span />', { text: n, class: 'ui-li-count'}))
.appendTo($list);
$list.listview('refresh');
});
});
