Can't Grab Value From Dynamically Added Form Element?

May 1, 2011

I am selecting an image as part of a html form. Once selected, jQuery assigns a user-defined attribute of the image to a hidden form variable and passes it to form handler. Problem is when I dynamically add images that can be selected. I am using live function to ensure that the dynamically added image is highlighted when clicked - but the user-defined attribute is not being grabbed by jQuery.

I think that when the page is first loaded, all the existing image attributes are loaded into the DOM, but when extra images are added with ajax, the DOM doesn't have the new attribute values, despite them appearing in the html on the page. I don't think I can use the live function in this instance, because an attribute is not an event. Out of ideas now. HTML/PHP, with jQuery:

JQuery :: Get Value Of A Dynamically Added Element?

May 11, 2010

I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.

Oh and that textbox is part of an array of textboxes, all of whose values i need.

JQuery :: Retrieve Id Of Dynamically Added Element?

Jun 14, 2011

I have the following html:

<div id = "container"></div>
<div id = 'containerItemTmplt' class = "ui-widget-content">
<div class='contentHdr' onclick="test(this)" />
</div>

i then use jquery to clone 'containerItemTmplt' and add it to 'container':

var copiedElem = $('#containerItemTmplt').clone(true).
.attr('id', 'paneI1')
.appendTo('#container');


This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.

However in my test method, when i inspect the element that was copied, the id attribute is an empty string:

function test(elem)
{
var parentItem= $(elem).closest('div')[0];
alert(parentItem.id); //<--this displays an empty string despite
}

JQuery :: Dynamically Added Element Cannot Be Removed / Solve This?

Oct 26, 2011

In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events. Does anyone now how I can solve this?

JQuery :: Get Form Elements Added Dynamically To Be Included In The Form?

Oct 13, 2010

I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"

Example
var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"};
$("#list1").addRowData(boxNo,myRow);

JQuery :: Loading Files - Script Element Is Dynamically Added To The Head Section Of Html

Feb 6, 2010

I came up with some code to load javascript files dynamically. But I've got problems..

When the script element is dynamically added to the head section of html, i think that the document.ready event fires once again and therefore the code sort of runs twice.

In the html page I call this method:

In the script test.js I have the function SayHi():

The SayHi method never gets called and alert('begin') & alert('getScript') get called twice in this sequence:begin begin getScript getScript.

Can't Dynamically Grab Script Object Properties / Make It Possible?

Jun 20, 2010

I've got a javascript object is "is" that has dynamically populated properties. I make an ajax call to my database to grab usernames associated with unique ID's and populate the javascript. I can call a property directly like this: aler (is.softUser1) or alert(is.softUser2) and show the corresponding values. However since what is being returned from the database is dynamic I may need to call is.softUser5 or is.softUser8 so I need to do that call dynamically. code...

and that obviously doesn't work.

Is there a way that I can dynamically call that property based on whatever value "user" is?

JQuery :: Grab Element Created With Append Function

Jul 27, 2011

I am not completely new to JQuery, but not a beginner either. Anyway, I want to do some advanced stuff like creating everything dynamically with JQuery. So here's the rough concept:
Step 1: Information get's collected
Step 2: Information will be written in divs, the divs will get an ID and will be displayed with .append()
Step 3: Setting css-propertys with the div's ID.
I can't grab the div which I created with .append.

Actually I can't access anything which was created with .append - for example if I want to get an .attr() - I can't do it with these elements. Is there a workaround or am I wrong:
$("#site").append("<div class='container' id=' " + containerId + "'>" + containerId + "</div>");
$("#" + containerId).css({
"left" : positionX + "px",
"top" : positionY + "px",
"background-color" : "#F000FA"});

JQuery :: Get ID Of Dynamically Added HTML Elements?

Aug 16, 2010

I am generating HTML based on user actions (in this case, populating a table with the result from AJAX calls).

In my context, I have a link where there is a Quantity field, which I would like to be editable. When I create the html, I give a unique ID to each row, (to reference to a JSON object), however I am unable to get the ID for said row, seeing as the DOM tree is parsed on the pageload and doesn't seem to update when I add elements to the page.

This means that $(this).parent('tr').attr('id') is not returning anything at all.

How would I make it so I can retrieve the ID of my row (which was created/added to the page after it was parsed)?

Populating Dynamically Added Drop-down Menus

Sep 16, 2010

I've got a database written in MySQL with a bunch of PHP interfacing with it. What I want to do is populate drop down menus on a form from this database.

The way I went around solving my problem is as follows.

Code:

Which calls the function from the search.js file, which performs the following operation:

Code:

With element2 being the appropriate preemtied dropdown box, and addOption defined as follows:

Code:

So far so good. This works and produces the correct list of elements in the first dropdown box if the first dropdown box is the target. Here is where things begin to go wrong: On this form I have an add more elements button which is defined as follows:

Code:

And addElement being defined as such:

Code:

While this does successfully create all the cells I want it to create, when I attempt to select Country from the resulting dropdown, I get an empty drop down wit only the "Search For" present in it.

Firebug then proceeds to flag array in selectorfunc above:

Code:

What i believe is going on is that for SOME reason the newly created drop downs aren't being passed js_countries correctly. Unfortunately I don't know how to fix it.

JQuery :: Cannot Remove Dynamically Added Elements / Sort It?

Oct 26, 2011

When the user select an option in a dropdownlist, new dropdownlist elements are added dynamically using jquery. When a user clicks on a new option i the first dropdown, I want all the dynamically added events to be removed so that I can render new ones. But it seems the dynamically added events haven't been added to the DOM, so they cannot be removed. Is it possible to remove them? In that case, how? I've read a lot about .Live(), but my problem is not regarding an event - I just need to reach an element(?).

JQuery :: Dynamically Added Image Not Appearing Consistently?

Nov 4, 2011

I have links that, when clicked, open up a larger image. If the link has the class of "sold selected" then a semitransparent "sold" image should dynamically load as well. What I'm noticing is that it seems to appear on every other click, and I don't know why.

I've created experimental files so as not to disrupt the functioning site. [URL]

I added the variable "linkClass" on line 18; value assigned on line 53 as part of the linker.click anonymous function IF statement on lines 106-108 at bottom

I also have an alert on line 105 just to prove to myself that linkClass was appropriately setting (it is). Images 4-12 should all have the "sold" banner attached, but no matter which of those I click first, the clicking previous/next makes the banner appear/disappear.
