Is it possible to append an event handler to a tag dynamically.
<input type="button" id="cmdNext" value="Next Page">
i want to be able to programatically loop through the buttons on a page and then add the onClick event. So my finally result will be the following:
<input type="button" id="cmdNext" value="Next Page" onClick="CheckValues()">
I am analyzing header tags for submitting forms online in order to better understand how htmlhttp forms work- signing in to gmail, yahoo mail, and amazon, using the network tab of google developer tools, to view the http headers of requests and responses, and learn where they come from. I am seeing very peculiar behavior in my browser's (chrome)request headers when signing into amazon. The form data, always has the following two header names appended to the second and third to last places of the form data query: x=(some random number), and y=(some random number).
There are no input tags getting dynamically generated,since when i tell google chrome to break on all subtree modifications, the site still sends off the post with the added parameters before anything gets modified, BEFORE crashing. There also is NO ajax call which is causing dynamically added data to be appended to the form post.My question is this: is there any way, using javascript, to instruct a browser, to append data as data, to a form post, WITHOUT the use of dynamically appended input elements, or ajax?
Trying to add new HTML elements to the document using the jQuery append() function it seems it doesn't add event handlers to the newly created elements.jQuery only seems to add these in Internet Explorer:
<a href="#" onclick="alert('...'); return false;">Test</a>
In Opera, Safari and Google, all my hyperlinks look something like this:
<a href="#">Test</a>
This code is similar to what I have written:
body.append('
<a
href="#" onclick="alert('...'); return false;">Test</a>');
I tried to append a table row to a table by clicking on a button. And inside the table, I put a link so i can click that and remove the row. I was using jquery.flydom plugin, by the way. [code]...

I found the bug ticket with similar problem: [URL] but it was closed as invalid. The problem still exists for me. I have the following live event: $("a:not([onclick])").live('click', ajaxLinkHandler); It's not applying to content loaded via $.ajax(...).responseXML which I used to append in the following way:
// withing ajaxLinkHandler
var content = $(loadedDocument).find("[component='"+ id +"']");
$(this.contentContainer).empty().append(content);
I got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.
I need to capture the click event, edit form action then re-submit the form with the captured input value appended to the end of the action. I would like the end url action to be google.com/tada

I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
Currently I am doing this:
What I'm actually doing is inserting the current time into an existing DIV and updating it every second. THAT all works.
What I want to do is also set an event for that div.... something like this:
Of course, the above doesn't work... and I'm not even sure what to ask for doing a Google search... because I get no hits (or maybe it's not possible).
I really don't want to edit the code itself (where that div is) because it's part of another app that may change as they update it and I don't want to have to re-patch every new release.
I have a form in which i have multiple textboxes and radio buttons.
The form is dynamic in that if certain selections are made fields appear/disappear.
This is controlled client side by javascript. The whole form is set up correctly.
However these forms then read off an oracle database. This populates the form. (in effect selecting certain options)
i would like to be able to recurse through the document, selecting which elements are checked and then run the associated onclick method.
So far i have this whacky non-functioning code: (it finds the correct elements, but how do i run the onclick method?)
function load() {
var tags = document.getElementsByTagName("input")
for (var i=0;i<tags.length;i++) {
if (tags(i).type=="radio" && tags(i).checked==true) {

The following is a very simple example of what I want to do take an
elements oncontextmenu and changing it dynamically onclick of that
same element. The code below will fail unless you change the line
document.getElementById('div1').setAttribute('onco ntextmenu',
someText);
to
document.getElementById('div1').setAttribute('onco ntextmenu',
function(){alert('World World');return false;});

I have a small script which dynamically creates select tags (they are placed within divs). Each select has a + and - sign next to it, and if you click the + it adds another select below that one, or if you click the -, it removes that current select.
I've made it so that if there is only one select, it can't be removed. So i made it like this, when i create a select, the remove button is inactive. When i click to add another select button, it becomes active. The problem is that the onclick event is not working with any browser except Opera. This is the code:

I have a form with many, many, many 'input type="text"' elements in it. I'd like to be able to dynamically add an 'onKeyDown' event listener. Here's what I've got, so far (I know it's wrong.)
Code:
function addEventToElement(formName,tagName,typeName,eventName,eventAction) {
thisForm = (typeof formName == 'string') ? document.getElementById(formName) : '' ;
thisTag = (typeof tagName == 'string') ? tagName : '' ;
thisType = (typeof typeName == 'string') ? typeName : '' ;
thisEvent = (typeof eventName == 'string') ? eventName : '' ;
thisAction = (typeof eventAction == 'string') ? eventAction : '' ;
if(thisForm != "") { // If elements are in a form, make sure ONLY those elements are affected
elem = new Array(); elem = thisForm.getElementsByTagName(thisTag); // array of all items of [tag]
alert(elem.length);
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
else { // Otherwise, any/all elements in a document/body will be affected
elem = new Array(); elem = document.getElementsByTagName(thisTag); // array of all items of [tag]
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
if((thisEvent != "") && (thisAction != "")) {
for(i=0;i<elem.length;i++) { // All elements are picked - let's apply some attributes
document.getElementById(elem[i].id).addEventListener(thisEvent,thisAction,false)
}
}
}
HTML Code:
addEventToElement('form_name','input','text','keydown','return numbersOnly(event,this);');
I hope I got the title right, anyway, I have a button element as shown below;
//Edit Image (Edit the current Item)
$("img[title='Edit']").click(function(){
var ajaxTranId=$(this).attr("id");
[code]....
for (x=0;x<=10;x++) {
var tempID = 'elementName' + x;
$(jq_escape(tempID)).bind('dblclick',function(event) {

How does one use the onResize() event to dynamically resize a web page according to the size of the user's viewport?
View 10 Replies View RelatedI have a function that dynamically creates a new div, part of the function looks like:

I have a <div> containing 3 buttons. The buttons have id's like this:
Button 1: btnFoo
Button 2: btnBar
Button 3: btnBaz
I'd like to add an click event to each button to call a function named [button ID]_click():
i.e.
btnFoo_click()
btnBar_click()
btnBaz_click()
So far I have this:
$("#divButtons button").each(function() {.
$( this ).bind("click",function(){
eval(($(this)[0].id) + '_click()');
});
});
This works but is there a way without having to use eval and still utilizing the lovely .each function?

Now my problem is that the above function gets called even when the cell has not been clicked, hope am clear enough,
I'm making an ajax call to my server and then, with the information I get back,ynamically creating HTML with jQuery, then appending it to my desired div. This part works excellently. The issue I'm having trouble with is I'm only returning five records, so I'm creating a span at the bottom labeled "see all", but even if I give that span a class,it's clearly not registering in the DOM because when I click it, my jQuery code doesn't even know it's there.My question: How do I get those dynamically generated elements to register in my DOM so they can be called by a jQuery click event?I realize that I can just do an inline javascript call to my function and that works fine(ish). The problem is, however, I want specific information about the particular span that I click, and if I call it inline, it doesn't send $(this) to my function... it recognizes $(this) as $(window), not as $(span that I clicked)
View 2 Replies View RelatedI would like to be able to tween an image dynamically from it's current position on a mouse over event. A good example of what I want can be found here. (the nav cloud) I haven't been able to find anything on jquery or anywhere else, so here's what I've come up with so far:

in the below code I am trying to dynamically add a button and an event listener to it.
Code:
<html>
<head>
[code]....
I'm trying to load dynamically some content and I'd like to fire a function when all the newly added content (including images, iframes and scripts in it) are loaded:
var htmlStr='html string including images, iframes and scripts';
$("#contents").html(htmlStr).load(function(){
alert("all images, scripts and iframes are fully loaded, you can continue");
})
According tohttp:[url]....(at least how I understand it) this should work: Theloadevent is sent to an element when it and all sub-elements have been completely loaded. This event can be sent to any element associated with a URL,images, scripts, frames, iframes, and the windowobject.Unfortunatelly my function is never called. For the meantime I found a workaround:
var html=$('html string including images, iframes and scripts');
var elements=html.find("img,script,iframe,frame");
var loadCounter = elemets.length;[code]....
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?
I have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function
LoadDestinationTable() {
$("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.
