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(?).
Is there something stopping this working, i'm dynamically adding a row to a table, then if they click the new row (or any row in the table) it should disappear...but it isnt working?
$('.addtocart').click(function(){ var omPartNo = $(this).next().text(); var supPartNo = $(this).next().next().text(); var cat = $(this).next().next().next().text();
I will be adding 3 additional <div class="slide"></div> after the first one dynamically on $(document).ready(). In the DOM, it looks like this. code...
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)?
I'm using the following plugin to include pagination functionality in my application In a nutshell I'm developing a map-based application using Google Maps. The markers that I display on the map and the corresponding information windows (infowindows) that are displayed when clicking on a marker are dynamically rendered from records in a database as the user moves around the map. So basically these DOM elements are dynamically removed and added throughout a user's sessionThe contents of these infowindows are what I need to paginate in cases where multiple markers are stacked on top of one another.
I call the paginate() function from the marker's click event handler if that marker's infowindow contains more than one DIV. It all works beautifully until the user triggers an event that causes the markers to redraw (e.g panning the map). Once the following happens the paginate() function mysteriously no longer works. 1. I click on a stacked marker that causes the paginate() function to execute 2. I then execute some event that causes the markers (and corresponding infowindow DOM elements) redraw3. I click on the same marker as was clicked in #1. No errors are generated and the paginate() function is definitely called but the pagination does not occur. I think it might have something to do with jQuery seeing the containing DIV's id as a duplicate ID? Could I be on to something there?
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.
I have cleated a bit of code that will dynamicly add a new line to a form so the use can add an infinat number of entires for this element.The code adds the form elemetns in IE and FF ok but when i click the submit button it does not submit the information from the dynamicly added elements in FF.Oddly enough IE works fine!Here is the code:
I am trying to insert and remove form element dynamically. What I was doing was some sort of recipe program where a user can prefer to add for elements as he/she is done inputting a recipe. He/She can also remove the ingredient if he/she opts to. Here is the link: [URL]
I already solved the problem but I am not sure if what I did is an efficient one. The thing I did was clone the first child of the form. But I realized that if I would put text inside the first child of the for, the duplicate field will also contain the same text as the first child which I don't want to happen. This is why, I set the display of the first child of the form as none. I am not sure if this would cause some problem when I would submit the whole form so that the inputs will be saved in the database since the first child is empty. I was thinking that as the form will be submitted, I would just remove the first child.
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.
So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...
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);
I have a function that dynamically creates page (form) elements with the option to remove it.
Code: divcounter++; var element = document.createElement("input"); ... element.onclick = function() {removeElement('sel' + String(divcounter))}; [Code]...
For some reason divNum in removeElement() always returns the latest value of divcounter. So if I add 4 form elements, and I want to remove the 2nd item, item 4 is removed and above fuction returns an error when I want to remove another element afterwards because it is trying to remove the 4th element again.
var newID = 'proj_assoc_' + $pnum; var $newTr = $("<tr></tr>"); $newTr.attr( 'id', newID ); $newTr.html( $output ); $('#ti_associated_project_numbers_table').append($newTr);
($output is html defined above that) Works fine for adding it to the table. My code for removing a row does not work. Here's that code:
var $row = $('#proj_assoc_' + $pnum); if ( $row.length>0 ) { $row.remove(); }
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.
I have a page I am working and I am having some trouble with: I need to show and hide areas based on a radio selection. I initally started using the show / hide feature in Jquery but the problem is the elements need to be removed but then put back if the user selects the radio buttonagain as it has form elements that have validaion on them. The validation is still trying to validate the form elements becuase they are still on the page but just not showing. This is the radio group the user makes the selection from:
When I add a tab, whose content is a form. The form is loaded by ajax $.ajax('url'); On ajax complete, I add a custom method for validation, which is supposed to get called when the "Upload" button in the form is clicked, but it never get called. I have searched and tried multiple things for two days now, and nothing works.
<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 }
The requirement is, "save" operation should happen only when the form is "dirty". i.e., users should be able to save only when they modify something on the form.
For this, I'm using "dirty form plugin", which works fine even when new elements are added. It internally uses ".liveQuery()" for adding events to new elements but it is degrading the performance very badly, since our forms are very large. I'm trying to replace it with ".live" of jQuery 1.4.2, but have a problem.
When new elements are added, I want to store their initial values and on blur, i want to compare them with their latest values. I'm able to bind event handlers to new elements using ".live()", but I want to get notified when new elements are added, so that I can make the above check. Is there any way how I can check this?

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.
I'm new to jQuery and I'm using the autocomplete pluggin. So far itworks great, but I wonder how I can autocomplete a newly input addeddynamically by innerHTML. It seems this new input element is not beingrecognized as is not firing the event.
I've been having problems getting jqmodal modal dialogs to display on links added dynamically by client side code. I've demonstrated the problem at the following URL: [URL] jqModal plugin here - [URL]
I have a dynamic form with fields named using brackets ([]). Validation is working for fields that existed on the initial page load, but when I add append the code for a new field, the validation events are, of course, not attached to the new DOM elements. What's the best way to accomplish this?
I am using jquery to copy a DIV containing some form elements. The copy is appended to the DIV in another DIV to allow an unlimited number of form elements to be sent. The problem is that none of the copy DIVs are being sent by the browser Firefox. There is some chatter via google, but nothing conclusive. I see the DIVs show up in Firebug. Could this be jquery related?
