JQuery :: Can't Select "dynamically" Created Element By Id

Apr 20, 2011

I'm creating some rows and cells in a table with javascript. I'm then trying to select these cells individually by id, but jquery can't seem to find them. It always returns length 0. The jquery code is, I believe, executing after the cell creation, so I would expect them to be in the DOM already. I can bind the click event to each cell by selecting the cell's class. Why can I select the class, but not the id? It would be nice to be able to do this rather than iterate through each cell in the class.

JQuery :: Dynamically Created Select Option Not Working?

Jun 24, 2011

I am creating a dynamo form but <select and <option does not show.

How do I make sure that they are created on the fly?

jQuery("#dump_data_box").append('<select id="thisid" name="value_name[]">');
and later
jQuery("#dump_data_box").append('<option');
///
if (v==k2) jQuery("#dump_data_box").append(' selected ');
//
jQuery("#dump_data_box").append(' value="'+k2+'">'+k2+'</option>');

But they do not show in the <div>.

Set Dom Element Class (if Element Was Dynamically Created)

Jan 25, 2006

hi everybody, didn't find this using the search :( this is my problem:
i create a dom element dynamically (<span>) and want to assign a class
attribute to it such that it has some css style, this works in ie, but
not in firefox :( here's the simple code:

<div id="somediv"></div>

var div = window.document.getElementById("somediv");
var span = window.document.createElement("span");
span.innerHTML = "span";
span.attributes.getNamedItem("class").nodeValue = "span_class";
div.appendChild(span);

so this works well in ie6, but firefox gives this error:
Error: span.attributes.getNamedItem("class") has no properties

if i run this code on a statically defined span (in the html file),
where a class attribute already is set:

<div id="somediv">
<span id="spanspan" class="">
</span>
</div>

changing the class to "span_class" works both in ie and firefox.

how can i fix my above code such that it works in both browsers? it
seems that on newly created dom elements the class attribute isn't even
there (to change it), how can i create it, and then change it?

JQuery :: Populating Dynamically Created Input Element Values Using Datepicker And .live Event Handler

Nov 15, 2010

I have a table with a date field in each row:

The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:

The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?

OPTION Elements Added To A Dynamically Created SELECT Box Via DOM Are Not Visible In IE

Sep 3, 2005

The code below works great in Mozilla.

In IE the selection box is created, and there is a drop-down box if I click
on the down arrow, but I can't see the OPTION text for each option. The
options are invisible, yet the box seems fully functional. I went into the
debugger and sure enough the selection box has "OPTION" child nodes with the
correct "value" and "text" attributes.

What could be wrong?:

Dynamically Add OnClick Event To Select Element

Feb 13, 2010

I have a function that dynamically creates a new div, part of the function looks like:
root = document.getElementById('rootbox2');
var oDiv=root.appendChild(document.createElement("div"));
with(oDiv){
id=ji;
className="workshopRow";
setAttribute("attending","");
setAttribute("attending_count","0");
}
var oText = oDiv.appendChild (document.createTextNode(""));
var oDiv1=oDiv.appendChild(document.createElement("div"));
with(oDiv1){
className="workshopName";
}
var oText = oDiv1.appendChild (document.createTextNode(""));
var oSelect=oDiv1.appendChild(document.createElement("select"));
with(oSelect){
name="select_"+ji;
id="select_"+ji;
className="workshop";
onchange="calc_subtotal("+ji+")";
}
var oText = oSelect.appendChild (document.createTextNode(""));
var oOption=oSelect.appendChild(document.createElement("option"));
with(oOption){
value="12";
setAttribute("price",10);
}
What I am looking to do is add an onchange event to the select element, not sure if i have programmed it correctly but it does not seem to work.

JQuery :: Hide Dynamically Created Content?

Jul 3, 2011

I have recently started exploring the world of jQuery and it looks incredibley rich and powerful! I am stuck on something, though. When I dynamically create a div

var divTag = document.createElement("div");
//Set the parameters
divTag.id = "divMaster";
//Create it and immediately hide it!

[Code].....

This is probably really obvious, but I cannot figure out why? Perhaps jQuery is looking for elements already in the original HTML, and my div tag was added to the DOM after loading the original elements?

JQuery :: Can't Access Dynamically Created Images By Their Id

Sep 13, 2010

The code below creates images based on a json feed, no problem. All images are created and the click function works perfectly, but... I can't access any of the images by their id's so I can't make thefunctionbehave as I wan't.

I first thought jQuery appended my image object as html and didn't insert it as a valid object in the dom, but as the click function is working that can't be it?

I found some other people had the same problem but they were using vanilla js, their solution was using .appendChild() but thatdoesn'twork in jQuery.

$.each(json.hotgames, function(i, item) {
var image = $('<img>')
.attr('id', item.uuid+':'+item.lane)
.attr('src', 'xxx')

JQuery :: Get A Reference For Elements That Are Created Dynamically?

I can see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.

JQuery :: Selecting Dynamically Created Elements?

Aug 18, 2010

Previously when developing my own modal windows I have been creating a "mask" div directly in my markup, in the CSS setting it to be display:none and then setting it to show() by jQuery when a button is clicked.

I'm sure there is a better way to do this but i'm getting a little stuck.

I tried adding the "mask" div and its content to the body using prepend() when my button is clicked but i found i then can't select any of the added elements in jQuery.

How can you select elements you have added to a page by jQuery?? Also if this is the right approach whats the best way to insert a block of html to a page??

JQuery :: Check Dynamically Created Input Values

Oct 8, 2010

When submitting a form, I would like to check the values of some fields first. These fields are dynamically generated by javascript after the page has loaded (that is, a user selected a value from a dropdown between 1 and 10, if 2 is selected, 2 inputs are generated, if 7 is selected, 7 inputs are generated etc). I think I understand that Jquery isn't aware of these items because they were created after the DOM was scanned. Is there any way I can 'refresh' jquery to make it aware of these new items?
