I'm working with a dynamic DOM here, and have called the jQuery UI datepicker to all inputs with a specific class name, in this case .date
It works great with the first, static, construct but when I clone it the event handlers don't seem to want to move over. I get the Firebug error:
inst is undefined
I tried looking into jQuery's new live() function but couldn't combine the two. Any ideas?
Ah, got it. Right after I append the HTML to the DOM I run this on all the inputs I'd like to have a datepicker pop up with. Datepicker adds a class to elements it has been attached to, so we can filter out existing inputs and only apply it to new ones.
$('.date').not('.hasDatePicker').datepicker();
I hope this helps people as I was Googling for days and didn't find anything!
You should also note that it would be faster to check for input.date in the new generated HTML by setting that as a context, rather than the whole page, as it will save time, due to this being a more efficient operation.
I had a similar Issue, I had multiple tables on a page and each had multiple datepickers, also on click of button "AddLine" it added a table row with dynamic HTML and datepicker.
I realized after a lot of search that my input date fields had no "id" defined they looked like this
<input type="text" class="datepicker" name="mDate1" value="" size=8 >
jquery was pointing all the date fields values to the very first date field defined on page, the calendar would popup on all the date fields but the value of 1st date field would change, I made a change to the html like this
<input type="text" class="datepicker" id="Date1" name="mDate1" value="" size=8 >
by adding a "id" and it started working, for the dynamic date fields I change the Id like this
var allColumns = $("#"+$tableId+" tr:last td");
$(allColumns).each(function (i,val) {
if($(val).find(":input").hasClass("datepicker")){
$(val).find(":input").attr("id",newId+$(val).find(":input").attr("id"));
}
});
You need to use the 'live' event to make it work with dynamic DOM. So, if the class for your datepicker inputs is 'date-input', following code will make it work:
$(document).ready(function() {
$('.date-input').live('click', function() {
$(this).datepicker('destroy').datepicker({showOn:'focus'}).focus();
});
});
This might be a little late, but all the suggestions above didn't work for me, I came up with an easy solution for this.
First, what is causing the problem:
JQuery assign datepicker to element id. if you are cloning element, then same id might be cloned as well. which jQuery doesn't like. You might end up with either receiving null reference error or the date being assigned to first input field regardless which input field you click on.
Solution:
1) destroy datepicker
2) assign new unique ids to all input field
3) assign datepicker for each input
Make sure your input is something like this
<input type="text" name="ndate[]" id="date1" class="n1datepicker">
Before you clone, destroy datepicker
$('.n1datepicker').datepicker('destroy');
After you clone, add these lines as well
var i = 0;
$('.n1datepicker').each(function () {
$(this).attr("id",'date' + i).datepicker();
i++;
});
and the magic happens
Use
$j(id or class).removeClass('hasDatepicker').datepicker();
It is working
Use jQuery selectors:
$(".mydatepicker:not(.hasDatepicker)").datepicker()
Multiple instances of the jquery-ui library on the page will cause this error too. Removing redundant instances work for my case
I experienced the same symptom, in this caused by having a td containing element with the same id attribute as the input,
<td id="fld_xyz"><input id="fld_xyz" class="date" /></td>
I know this isn't ideal anyway, but it's worth knowing that the datepicker component seems to be relying on the uniqueness of the id.
I had this problem. My situation ended up being I had another element with the same ID as the input with the datepicker.
Today I faced the same issue... I am using datetimepicker plugin in my application.
Also using jquery's default datepicker too. When ever I am invoking them both on document ready I am getting the error inst is undefined.
$(document).ready(function(){
$(".datepickerCustom").datetimepicker();
$(".datepicker").datepicker();
$("#MainForm").validationEngine('attach');
....
});
So I changed the code to invoke before document ready like below:
$(".datepickerCustom").datetimepicker();
$(".datepicker").datepicker();
$(document).ready(function(){
$("#MainForm").validationEngine('attach');
....
});
Now every thing is working fine. No problems.
I had a similar problem with data picker not working after a first call. I found an answer to my issue here:
http://www.stemkoski.com/problem-with-jquery-ui-datepicker-dynamic-dom/
I was cloning sections dynamically from template and inadvertently including the class that datepicker adds once its called:
hasDatepicker
I placed my first datepicker call after I clone the template and that did it. I then added a datepicker call after each instance of clone:
$(source).clone().appendTo(destination).find(".datepicker").datepicker();
After trying many of the answers here, this is what worked for me and is showing on the first click/focus
function vincularDatePickers() {
$('.mostrar_calendario').live('click', function () {
$(this).datepicker({ showButtonPanel: true, changeMonth: true, changeYear: true, showOn: 'focus' }).focus();
});
}
this needs that your input have the class 'mostrar_calendario'
live is for JQuery 1.3+ for newer versions you need to adapt this to "on"
See more about the difference here http://api.jquery.com/live/
If it still doesn't work, it is because of the cloned id. You can completely remove datepicker like this:
$(selector).removeClass('hasDatepicker').removeAttr('id').datepicker();

Here is what I am trying to do.
If the user makes a selection from the suggested options then I display a div tag using jquery. I use onCompleteTopics to fire this event.
Now when the user makes any changes to the text box I want to hide the div tag again unless the user makes a selection from the suggested options.
How to fire the text changed event on jquery struts2 autocompleter.
I make a div tag visible when the user selects something from the suggestions using onCompleteTopics.
However if the user changes the text in the field I want to hide the div tag again.
But I am not able to find the right event for the same.
After trying a lot of permutation and combination I managed to figure out the solution. Its not straightforward maybe not the ideal solution but it works.
Struts Code
<sj:autocompleter
theme="simple" name="userName" id="idautocomplete"
href="%{fetchList}" onSelectTopics="complete" onSearchTopics="textchange"
loadOnTextChange="true" loadMinimumCount="3" />
Note I have used onSelectTopics and onSearchTopics but this itself do not solve the problem. I have to use some jquery along with this.
jquery
var gvar;
$.subscribe("complete", function(event, data) {
gvar = data;
setTimeout(delayfunc, 0);
});
$.subscribe("textchange", function(event, data) {
$('#idBizAccess').css("display","none");
});
function delayfunc() {
$('#idBizAccess').css("display","table-row");
}
The unusual part here is setTimeout with delay 0. I tried calling the function directly but it doesn't fetch the selected value instead it just fetches the value that is typed in the autocompleter field.
Now it works as per the requirement.
I am using Shield ASP.NET MVC charts on a page. I need the charts to initially show data for my visitors, and I need to provide the user the possibility to hide the charts by clicking on the corresponding button(s). For this purpose I use the following function:
<script>
function HideChart() {
document.getElementById("DataSpot").innerHTML = "";
}
</script>
And I am placing the charts as follows:
<p id="DataSpot">
#(Html.ShieldChart()
.Name("chart")
.PrimaryHeader(header => header.Text("Profile Hits"))
.Export(false)
.AxisX(axisX => axisX
………..
)
</p>
<button onclick="HideChart()">Hide Chart</button>
The problem is, that when I click on the button, nothing happens.
#user2492467,
Do you need to hide the chart or do you need to wipe out its content? If just hiding the chart, the approach suggested by Chris would work just fine. However, if you need to irrevocably wipe out the chart from the page altogether, then clearing its content is not enough. Only removing the rendered chart markup would open the door for memory leaks, as references to the DOM nodes may remain in the chart javascript component.
A better approach would be to find the javascript component instance and call its .destroy() method. This will ensure the component is fully destroyed and no memory is leaked:
$("#DataSpot").swidget().destroy();
Note that you still need to give your chart a name using the MVC wrapper's .Name("DataSpot") method just like Ed suggests. This will give your chart's HTML element an ID that you can use with jQuery to find the chart instance.
The .swidget() method is a standard jQuery extension method added by the Shield UI javascript framework. It returns the javascript component instance associated with the element matched by the jQuery selector. This is how you find the chart instance.
How about:
<script>
function HideChart() {
document.getElementById('DataSpot').style.display='none';
}
</script>
You should also update your button:
<button type="button" onclick="HideChart()" value="Hide Chart" />
Actually there is something happening, obviously not the thing that you need. This is because you need to wipe out the rendered chart by referencing its container.
The element is fine and if you put some text in your function and execute it you will see that it will appear on the appropriate spot. However to hide the chart you need to use it’s name. In other words the following statement:
document.getElementById("DataSpot").innerHTML = "";
should be changed to
document.getElementById("chart").innerHTML = "";
or you may rename the chart to
.Name("DataSpot ")
and remove the P element in both cases since it makes no use.
I've been using jQuery UI with Bootstrap and I seem to run into a problem that I haven't had before. I'm not sure what has changed; I've tried setting back different version of jQuery and I didn't update the jQuery UI in the meanwhile. So I'm not exactly sure what broke.
The error from the console when I click on any date in the datepicker returns:
Uncaught TypeError: Cannot set property 'currentDay' of undefined
The code is fairly straightforward as one would expect from a datepicker:
$(".datepicker").datepicker({
dateFormat: 'dd-mm-yy'
});
With the following HTML:
<input type="text" class="datepicker" />
Is this a bug that should be reported (since no other Google matches turn up) or is it something else I've missed?
I've found the solution. After a long time of debugging I figured out that there was a <div> that had the exact same ID, lying higher than the input field. Therefore the script took the first instance that contained the ID and picked the DIV instead of the input field.
I removed/renamed the DIV and it worked fine again.
The above jQuery datepicker error is generally caused by having a duplicate controls with the same ID, no matter whether you use id or another selector like css class or field name to instantiate it.
I solved this with create new ID for HTML DOM object. There is duplicated Id.
Try to add new ID for HTML DOM object.
I was having this error also. I found that elsewhere on the form I had some label 'for' attributes that did not match ids on the form inputs - seems like this might confuse datepicker too. Once I fixed those up, everything worked fine and the error went away. Take Andreas' advice (+1 for that!) and validate your forms - Chris Pederick's Web Developer Toolbar gives you an easy way to validate as you go.
put a selector.
<script> $("#formID #duplicatedId").datepicker({language: 'he'});
</script>
FormID: Id of the form that contains input.
duplicatedId: input element's Id.
In my case I was triggering the datepicker from a div against a hidden input field and getPos(a) was causing an undefined message on the variable "a". I experimented with moving the hidden input field outside of a div and that did the trick. Note that the input field was findable by jQuery no matter where it was, so that was not the problem - it was with positioning. Hope this helps someone else.
Might be two input box having same class without different id and for that you are trying for date picker. If it is there give two different id it will work.
I've ran into this problem too, and i was 100% sure i did not use duplicate id.
After some debugging i found out a reason - i was using DataTables mod, which duplicates contents of tfoot, thus creating exact copy of datepicker elements. And i had this datepicker inputs in tfoot row.
Fixed that issue with:
table.find("TFOOT").find("TR:first").remove();
Which is called AFTER table.DataTable(....)
This removed original, zero height row with all contents;
I need to set up two jQuery UI date pickers to always be displayed. I know there's an easy way to do this with DIVs, but I can't find anything on how to do it for inputs. I've tried the "show" method in the jQuery UI documentation, but that just acts as a click on the input on page load, which isn't what I'm looking for.
I just tested the code below and it always remains on the page. You will need to handle the selection/click events by passing options the datepicker in the javascript. I added the JS for when the user selects a date... that should give you enough to go off of.
HTML:
<div id="test"></div>
<input type="text" id="date_input">
Javascript:
$('#test').datepicker({
onSelect: function(date, obj){
$('#date_input').val(date); //Updates value of of your input
}
});
For the Jquery UI tag-it widget, I'd like to disable text input into the class="ui-widget-content ui-autocomplete-input" textbox which contains all the tags.
My purpose is to just allow certain people the ability to delete inappropriate tags, but not allow anybody to add tags (which are auto-generated).
Is the best thing for me to edit the tag-it .js file and add a disable="disable" for that field? If I do that, won't that prevent the contents of that field from being submitted? Or does that matter as long as the associated hidden field is submitted?
Or is there a better way of doing this (an overriding style?) without modifying the tag-it file itself?
Thanks,
doug
In tag-it.js I replaced this line:
this._tagInput = $('<input type="text"').addClass('ui-widget-content');
with this:
this._tagInput = $('<input type="text" readonly="readonly"/>').addClass('ui-widget-content');
adding the readonly="readonly" attribute. That had the desired effect of preventing input but still allowing users to delete inappropriate auto-generated tags.
I had the same question as original op.
But as the question is 2 and a half years old, and tag-it version is changed.
The accepted answer needs to be updated to the folowing in
tag-it.js around line 478:
from:
if (this.options.readOnly){
tag.addClass('tagit-choice-read-only');
}
To:
if (this.options.readOnly){
tag.addClass('tagit-choice-editable');
// Button for removing the tag.
var removeTagIcon = $('<span></span>')
.addClass('ui-icon ui-icon-close');
var removeTag = $('<a><span class="text-icon">\xd7</span></a>') // \xd7 is an X
.addClass('tagit-close')
.append(removeTagIcon)
.click(function(e) {
// Removes a tag when the little 'x' is clicked.
that.removeTag(tag);
});
tag.append(removeTag);
}
This is under the documentation of git repository having the documentation, under the Properties section:
$("#myTags").data("ui-tagit").tagInput.addClass("fancy"); //Obviously
if you want to do something with class...
This translates to the solution for this below, in my personal implementation style, and probably the only way I could get this to work:
$("#myTags").data("ui-tagit").tagInput.prop('disabled' , true);
This is if I understand your question correctly.
Note: ReadOnly does not make the tags un-editable.
As far as going through the tags, you could use ..
var x = $("#myTags").tagit("assignedTags");
Make it as an input field, and that ensures its "singleFieldNode" meaning tags are , (comma) separated. That way you can parse through it (split for commas(,) into an object, or however you want to do it)
PS: To apply any of the snippets above, simply change to the "id" of the HTML element that contains TagIt, and your code would work correctly.
