Adding An Event To A New Element
Nov 22, 2005
I am trying to display a notice to users whose browser does not support a method for adding an event. However, I want this notice to appear in a DIV rather than in an annoying alert box each time the page loads. I would also like this DIV to go away if it is clicked on. However, I can't get anything into the onClick attribute in Firefox 1.5 or Internet Explorer 6.
var alert_element = document.createElement('div');
alert_element.style.color = 'darkred'
alert_element.style.border = ƈpx solid darkred'
alert_element.style.padding = Ƌpx'
alert_element.style.cursor = 'pointer'
alert_element.innerHTML = '<b>Your browser does not support the addition of event listeners!</b>'
/* Remove the alert element when clicked. */
alert_element.onClick = "parent_element.parentNode.removeChild(this)";
/* Create the temporary status message element. */
parent_element.parentNode.insertBefore(alert_element, parent_element.nextSibling);
The "parent_element" is already declared before this is reached. There are no errors displayed and the new DIV element shows up just as expected. However, clicking on the DIV does nothing.

As far as I understood, stopPropagation() is supposed to stop events bubbling 'up' though the element tree (through parent elements). Eg. If I use stopPropagation() on a click event on an anchor element in a list, the event would not be triggered on the list. In my code I have a popup div, that needs to have stopPropagation(), as a click on the document (everywhere other than the popup) will hide it. When I add an element to the popup that has a live click event, the live click event is never called, even though it is a child element of the popup. Shouldn't the live click get called first? If I remove the stopPropagation all is well.. some code:
$('#a_test_link').live("click", function(e){
e.preventDefault();
alert('done!');
});

In a loop, I add some Div block and different event on each of them. But it was always the same event ???
for (var i=0;i<obj.length; i++){
var c = obj[i];
var $line = $(document.createElement('DIV'));
$line.html(c["name"] + " (" +c["cp"] + ")");
$($line)
.appendTo("#ville-selector")

I wanted to add a onclick event handler to an image in a loop cos I have a dynamic number of images. The problem is I also need to pass a parameter. This works in Opera 8, but doesn't work in IE:
document.images[i].onclick = "javscript: ShowDesc(" + i + ");";
What am I missing?

I have a situation on my website similar to this:
<ul id="menu1" class="menu">
<li>
<a href='javascript:myFunction(0)'>Hello</a>
</li>
</ul>
This makes a link that calls myFunction(0) when I click it. Now I want to add a popup whenever the user clicks the link (but I can't add it to myFunction for some reason), so I add an event listener to this <a> in the $(document).ready() function:
$('ul.menu li a').click(
function() {
alert("hi");
});
Now the the popup does appear, but it doesn't execute myFunction(0) anymore.
So finally my question: is there a way to pass my <a>'s href to this click-function and makes it execute? Or is there a better way?

This should be simple, but I can't figure it out.
I have the below external js file:
I need to add an onclick handler to the checkbox fields:
The form is being created dynamically through a database, so I can't add the onclick event to the fields themselves.
How would I add the onclick function to the script instead?

I can't seem to add an onclick event to an image. I'm sure I am doing something wrong as I am very new to Javascript.
This is a part of my javascript code that is in the head and body of my HTML file:
The image that is displayed is not clickable, and therefore the function redClick cannot be called.

I am trying to add an onclick event to a div from within javascript. Basically i have 2 divs containing arrows ("<<" and ">>"), used to toggle the week of a calendar. At the moment the ajax communication and handling of the response is working fine. After i processed this, i want to switch the arrows, basically add onclick to the previously non-active arrow and then nullify the previously active arrow. How do i go about doing this? Below is my attempt at solving it, with no luck. Code:

My name is juan and recently started html programming. I have a web page with a drop box with the name of states.
Code:
<option value="">Alabama</option>
<option value="">Alaska</option>
I can add a onclick="code here" to the tag so that when the drop box alabama is selected it triggers the onclick event. Im using Ibox in order to have a image of the state open.
Code:
<a href="images/large/image_1b.jpg" rel="ibox" title="alabama at 1024x450!"><img
src="images/small/image_1.jpg" alt=""/></a>
the above is a <a> link tag correct? How do I go bout adding the above code into the onclick event?

In IE6 and below, when using createElement and appendChild to add a new select element to the page, it automatically selects the first option.
the page relies on using the onchange event of the select element, and if there is only one option and it is selected, there is no possible way to fire the onchange event.
To get around this, i've had to use innerHTML to build the select element, which I feel is dirty so I want to clean it up.
Any idea's? I have already tried setting each option's selected value to false, etc but nothing other than using innerHTML seems to of worked,.

I have a setting where I construct an image reference which I then append somewhere in the DOM, like so for instance:
var one = "<img src = "test.jpg" ";
var two = "/>";
var my_img = one + two;
and then I add it to DOM using after() function. It works fine. However, I also need to add a click event to it. I tried to do this:
my_img.click(function(){
});
and then append it using after(), but it doesn't seem to work. One thing I can think of is append it after a certain ID, then look for it as a child of that ID and add click to it this way. I haven't tried this, but it'll probably work.

Im trying to develop an AJAX application which updates a <select> list with a series of <option> tags when the user makes an entry in a field.
Therefore, my ajax application needs to dynamically create <option> tags and append them to the <select> list on the form. I have got this working in all browsers. However, i do not know how to add an "onclick" event handler to each <option> tag that is dynamically created in my javascript code.
Code:
As you can see, i create an option javascript object for each new <option> tag and add it to the <select> list. This works. But how can i also add an "onclick" event handler in the javascript code?
