JQuery :: Binding Events To Dynamically Created Elements That Do Don't Exist At All On Page Load
Jul 26, 2010
In the examples for live() and delegate(), the selectors match at least one element that already exists. Will either of these commands work on elements for which there is no match at all on page load?
In my case, I want to bind a keyup event to the textareas that jeditable creates. I could probably create custom plug-in (to the plug-in :) to do the job, but I'd like to use live or delegate if they would work.
I have a page with a div that contains other divs. In the outer div, I have links that add new divs inside. I also have a link outside the outer div that adds more of those outer divs to the page (with an inner div, and the same links to add more). This works on the div that is hard coded on the page, but when I use the link to add additional container divs the links inside there to add more inner divs does not function.
while creating this i am attaching the change event using live() function. On changing the above option i am recreating the above dropdown again. This dropdown in under a div .For eg:it has an id=1. During the time of recreating the above dropdown,i am dettaching the event handlers using die() and after that i remove the div with id=1.Again i will create a div with id=1 and a dropdown.
The problem now is that when i try to change the option two change events are triggered.I think the die() method haven't worked. Is it because i have created the dropdown under the div with same id?
I've come across an issue where I've got a dynamically created popup class that despite appearing to be bound according to Visual Event does not fire on clicking the closebutton attached to it. I'm not getting any errors in firebug and by setting breakpoints I've verified we are not reaching the code to execute. Ruling out the usual suspects such as obvious spelling mistakes/ swapping out jquery versions 1.3/1.4/1.5 doesn't make any difference.where else I can look?Here is the original function:
$this.find(".close").live('click', function() { var $this = $(this); $this.parents("." + sets.popupClass).remove();
This is my first time here so I hope I'm not posting to the wrong forum. If this has been answered before, please direct me to the corrent post.I've created several dynamic checkboxes with with following code:
<code> var pnl = document.getElementById("pnlSalesPeople"); for (i = 0; i < sales.length; i++)
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.
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??
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 am sure this question has been raised and answered before, but I can't seem to find an answer that works for me. I hope I will get an exact response here. Here's my issue - I have my index.html that has its own $(document).ready method and everything pretty much works within it. I am trying to dynamically load a page to replace part of index.html (let' say the #inner_content ID) -
I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++) { var newDiv = document.createElement("div"); newDiv.setAttribute("id", tables[i].name); newDiv.setAttribute("name", tables[i].name); newDiv.setAttribute("class", "hidden");
I am creating textboxes dynamically using the following code:
[Code]...
I want to have a function that will remove textboxes and the newline that is created. I have the following function to remove the text boxes but I cant remove the new lines that were created so an empty space is left on the page.function RemoveElement() {
var d = document.getElementById('spanManualInput'); var oldbox = document.getElementById('Value'+i); d.removeChild(oldbox); d.removeChild('br'); }
I'm created a set amount of dynamic elements based on some elements in another form to try to submit them when the current form is submitted and this just doesnt work. It creates all the elements succesfully and puts in their proper names and values, but on the next page they are not available in $_POST in php.Here's the exact javascript I'm using, I tried appendChild and innerHTML,
Code: var elem = document.getElementById('submission_options').elements; for(var k = 0; k < elem.length; k++) {[code].....
Question: I need a few good idea on the best way to save a webpage (even better a node of a webpage) in which a user has created new elements. (via javascript?)
Concept: User creates elements on a canvas (via Javascript) then has the option to save the layout of those elements. upon pushing save the Javascript packages the created and/or changed elements and sends then to the server to be processed by PHP and saved.
Hurdles: saved data must include style attibutes, text, child nodes and so on. The when other users view the page PHP will build the elements from the original user saved file.
What I have Done:I have managed to use Xmlserializer to output the "canvas" element in firefox and safri I have used .outputHTML in IE to complish the same thing.Of course there are a few differences when comparing the two strings, mainly having to do with commas.IE does not surround id's in commas and FF does. This has me thinking there has to be a better way more consistant way. on other ways to save dynamic elements using Javascript, and PHP.
I have a series of images with an animation bound to mouseover and mouseleave events, and I'm trying to get my head around adding a click event that would prevent the mouseleave animation from occurring only for the image that was clicked, preserving everything else as is (until another image is clicked). I've discovered .stop() and I think I'm getting close, but some part of the logic is still escaping me.
I have a menu that I have constructed through HTML/CSS/JavaScript. Javascript handles the mouseover and mouseout events to set the background of the menu item/table element with an image. It works great. What my issue is right now is that when the user loads the Home page, I want that to have the background of the item already set. I had a function to do this with a switch clause in a separate javascript file. This function was called immediately (left it outside of any functions so it would execute first). But I'm getting an error because the actual element (a table) to set the background doesn't exist yet.
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.
My requirement is to submit html form with Attachment filesfor a web based email application.I have used javascript to achieve Attach more files functionality.When user clicks on ttach more files link, following HTML is dynamically generated using javascript:
<input type=file name=some_namesize=/>
The Javascript code is:
function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length;
I'd like to have a hyperlink on a page, that when clicked reveals some hidden text below the hyperlink AND at the same time opens a new browser window to a specified URL (which would have been declared in the HTML code NOT the jQuery bind code). There will be several of these 'Click here to reveal password and open site' hyperlinks on the page. Will this scenario cause a problem in the sense that if you click on one hyperlink then all of the reveals would be triggered and numerous windows would be opened?
I've noticed I can bind and trigger events on objects that are not DOM elements. However this appears to be an undocumented feature, as the docs explicitly refer to the "DOM element" when discussing things like event.currentTarget. Is it safe to depend on code like the example below working in future jQuery releases?
So the active tab is set in the HTML to Individual by default.The following jQuery sets the active depending on which one is clicked.
Code:
$('ul#coverTabs > li').live('click', function() { // Clickable tabs // Removes default class applied in HTML and onClick adds 'currentTab' class
[code]....
what i want to achieve is when a user clicks a tab we call the XML document. The appropriate tab name is fetched and subsequently when a user clicks on a column under that tab the appropriate level cost data is displayed on the page.
I have a link that has a UL drop down. When I click off of both the link and the UL I want the drop down to disappear. Right now it only disappears after I click off of the link.
I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.
Here is the javascript:
Code:
function add3<%=strGoalCount%><%=strObjCount%>() { var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>'); var numi = document.getElementById('theValue'); var num = (document.getElementById('theValue').value -1)+ 2;
I am trying to "ajaxify" my site. Now I have one problem:
$("#posts").children().remove(); $("#tag-sidebar").children().remove(); $.each(data.Tags_Sidebar, function (indexInArray, valueOfElement) { var insert = $("<li>");
[Code]......
Now when I click one of those links (href1, href2, href3) generated, the click event won't execute! What's the problem? Also, is it right that I have to transfer the valueOfElement over, like I did? What does stopEventPropagation do? Prevent the href from being navigated to? That's what I am trying to do.
I am learning jQuery now and have a big interest in this javascript framework. I am trying to bind an event to more than one element. I won't meet any problem if using selector. But now, I've created a function which I will pass the element. And I need within this function, to bind the code. This is my current code :
function updateDay(dayObj, monthObj, yearObj){ //I want to bind both monthObj and yearObj. yearObj.change(function(){ //do something }); monthObj.change(function(){yearObj.change()}); } $(document).ready(function(){ updateDay( $("#day"), $("#month"), $("#year")); });
As you can see, I must bind twice, once for yearObj, the other for monthObj. Is there anyway to bind the change() event only once? If there are some logic mistake in using function or such as feel free to point out, since I still haven't read all the documentation yet.
