I am trying to use jquery mobile, I want to retrieve the list of checked box. Here is my code to populate the list of checkbox:
for( var i=0; i<results.rows.length; i++ ) //Remplir tableau liste des identifiants étapes
{
$('#lbtn2').append("<input type='checkbox' value="+
results.rows.item(i).Phrase+
" name = "+results.rows.item(i).QuotationParDefaut+
" id="+results.rows.item(i).idPhrase+" />");
$('#lbtn2').append('<label for='+
results.rows.item(i).idPhrase+'>'+
results.rows.item(i).Phrase+'</label>');
}
And here is the code that allows to retrieve the list of selected labels.
$("#lbtn2 input:checked").each(function()
{
tab_phrase_selectionner[j] =
$("label[for='" + ( $(this).attr("id") ) + "']").text();//Pour le fichier A1.js
j++;
});
The problem is that if I select six checkboxes it returns only 3 checkboxes. Anybody have an idea about this problem?

I'm using Struts and I have a multiple html:select like this:
<html:select styleClass="selectedFichier" multiple="multiple" property="listFichiersSelected">
<html:optionsCollection property="fichiers" value="id" label="nom"/>
</html:select>
I use the Jquery Chosen plugin to select 1 or more files and it gives me an array of Strings.
$(".selectedFichier").chosen({ disable_search: false, allow_single_deselect: true, placeholder_text_multiple: " ", width: "400px" });
But when I want to make a modification and therefore remove all my files from my multiple list, the first index of my string array does not want to be removed so I always have one left when I validate my form.
Here is the code of my actionController for my string array when I validate:
// On récupère la liste des fichiers sélectionnés
ArrayList<FichierUnite> fichiers = new ArrayList<FichierUnite>();
for (int i=0; i<dataBean.getListFichiersSelected().length ; i++) {
String codeFichier = dataBean.getListFichiersSelected()[i];
Fichier fichier = exploitationAd.getFichier(Integer.parseInt(codeFichier));
if (fichier != null) {
FichierUnite fichierUnite = new FichierUnite();
fichierUnite.setUnite(dataBean.getUneUnite());
fichierUnite.setFichier(fichier);
fichiers.add(fichierUnite);
}
dataBean.getUneUnite().setListfichiers(new HashSet<FichierUnite>(fichiers));
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);
});
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;
With say 5 fields in the DB, I know the columns that can be queried and use:
function getDetails_success (tx, results) {
var len = results.rows.length;
for (var i=0; i<len; i++) {
var content = results.rows.item(i);
buf += '<tr '+ content.key1+'>';
buf += '<tr '+ content.key2+'>';
}
}
and so on.
What if I have 50 fields, of which 5 random fields has to be displayed. Do I get the keys from the resultset? What are the various ways I can approach this?
If 5 random fields are selected by the user to be displayed, put all of them in an array.
var randomFieldsSelected = new Array();
randomFieldsSelected.push(selection1);
randomFieldsSelected.push(selection2); //and so on
Instead of the above for loop, put,
for (var i=0; i<len; i++) {
var content = results.rows.item(i);
buf += '<tr '+ content[randomFieldsSelected[i]]+'>';
}
(The above works,provided, the database column names match with 'selection1' and 'selection2' etc)
I currently have a filter working on a fusion table rendered as a Map Layer, and I want to zoom to best fit all of the data whenever the filter is changed.
I figure I need to wait until the query is applied and then iterate through the markers to find the min/max x & y locations and pan to that rectangle, but I don't see a way in the Maps api to access the markers of a layer.
Anyone have an idea how to do this?
The short answer is no. To me this is one of the shortcomings of dealing with Fusion Tables via the Maps API. E.g. wanting to display a count of the results of my most recent query. But there is a work-around through the "undocumented" JSONP API to Fusion Tables. I've had great success using it but I must credit Robin Kraft with informing me about this API.
http://www.reddmetrics.com/2011/08/10/fusion-tables-javascript-query-maps.html.
Here's some code which allows you to re-execute your most recent query via an AJAX JSONP request and do what you want with the results, such as calculating the bounding-box. Note: this example uses Jquery for the AJAX JSONP calls. This example creates a <table> display but can be modified as needed.
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
// Example call
getFTData(tableid, 'latitude,longitude', example_dataHandler);
<script>
// Globals same for all requests
var queryUrlHead = 'https://fusiontables.googleusercontent.com/fusiontables/api/query?sql=';
var queryUrlTail = '&jsonCallback=?'; // ? could be a function name
// getFTData()
// table_id - Fusion Table id MUST have public permissions
// col_list - comma separated list of FT column names
// successFunction - function to parse the CSV results (see exampleParser below)
//////////////////////////////
function getFTData(table_id, col_list, successFunction) {
var query = "SELECT " + col_list + " FROM " + table_id;
var queryurl = encodeURI(queryUrlHead + query + queryUrlTail);
$.ajax({
type: "GET",
url: queryurl,
dataType: "jsonp", // return CSV FustionTable response as JSON
success: successFunction,
error: function () {alert("AJAX ERROR for " + queryurl ); }
});
}
function example_dataHandler(d) {
// get the actual data out of the JSON object
var cols = d.table.cols;
var rows = d.table.rows;
var row_count = 0;
var results = '<table border="1" cellpadding="4">';
results += '<tr>';
for (var i = 0; i < cols.length; i++) {
results += '<th>' + cols[i] + '</th>';
}
results += '</tr>';
// loop through all rows to add them to the map
for (var i = 0; i < rows.length; i++) {
// Per the expected columns
results += '<tr>';
for(j=0; j < rows[i].length; j++)
{
results += '<td>' + rows[i][j] + '</td>';
}
results += '</tr>';
row_count++;
}
results += '</table>';
results += '<br />';
results += 'Row Count: ' + row_count + '<br />';;
document.getElementById("program_select").innerHTML = results;
}
</script>
Since retrieving the count of recent Fusion Table rows returned is common, I'm adding a snippet of how to do that.
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script type="text/javascript">
var tableid = 3167783
var where = "WHERE type = 9";
getFTCount(current_table_id, where, displayCount);
// Globals same for all request
var queryUrlHead = 'https://fusiontables.googleusercontent.com/fusiontables/api/query?sql=';
var queryUrlTail = '&jsonCallback=?'; // ? could be a function name
///////////////////////////////
// Get Counts from Fusion Tables.
// table_id required
// where optional "WHERE column == 'value' " where clause for count()
// successFunction callback required
///////////////////////////////
function getFTCount(table_id, where, successFunction) {
if(!table_id){
alert("table_id required.");
return;
}
if(!successFunction){
alert("successFunction callback required.");
return;
}
var query = "SELECT count() FROM " + table_id;
if(where){
query += ' ' + where;
}
var queryurl = encodeURI(queryUrlHead + query + queryUrlTail);
$.ajax({
type: "GET",
url: queryurl,
dataType: "jsonp", // return CSV FustionTable response as JSON
success: successFunction,
error: function () {alert("AJAX ERROR for " + queryurl ); }
});
}
function displayCount(d) {
var count = d.table.rows[0];
alert(count);
}
</script>
If your data is in a fusion table, then use the fusion table's sql api to find the Max/Min val for Lat and Lng respectively:
https://www.googleapis.com/fusiontables/v1/query?sql=SELECT
MINIMUM(Lat) AS MinLat, MAXIMUM(Lat) AS MaxLat,
MINIMUM(Long) AS MinLong, MAXIMUM(Long) AS MaxLong
FROM <table_id>
See here for full details on api: https://developers.google.com/fusiontables/docs/v1/sql-reference. (One thing to remember is to ecodeURI this sql statement)
This returns those for value to json array. And as I'm sure your aware, use these values to set your map's 'center' and 'zoom' parameters.
