Add OnClick Event Handler To Each Banner
Feb 11, 2009
I've successfully used the Random-Order javascript on my site for years to shuffle around a number of banners on my main page.I now want to add an onClick event handler to each banner so that I can use Google Analytics to track those exit links, but I can't get the script to work when adding the onClick; the banners just don't show up on the webpage then. I'm pretty sure that some coding needs to happen in the function area below the content section, that just putting the onClick in each item won't do it, but I don't write this stuff, so I have no clue what to do to make it work right. Here's the script WITH the onClick code I would like to add in red. If you were to remove everything in red, the remaining code would be exactly as it currently appears on my site and works properly.

i have registered a validation function as the onclick event handler. It runs for the first time but does not run when i click on the button the second time. ( this is because i have put an aert box in the validation function and it does not show up when i click on the submit button for the second time)
here is the code
Code:
<input type="submit" value="Submit" action="submit.php " onClick="return validate('add_item_form');">
Code:
function validate(form_name){
validate=1;
string="";
[Code]....
when i leave all the fields of the form blank then the error message is displayed. But when i click on the submit button again then the validation function does not run.

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?

I have a button on a page that is created with the <input> statement - this statement also contains the event handler onClick. The button displays correctly on the page but the event handler is not working - I know this as I put a simple alert at the beginning of the function PrcsBtn1.
<script type="text/javascript" language="javascript">
function PrcsBtn1()
{
var data2 = new Array();
[Code]....

I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons:
<input
id
="btnUpdate21"
type
="submit"
value
="Approve"
synchId
="21"
/>
<input
id
="btnUpdate22"
type
="submit"
value
="Approve"
synchId
="22"
/> .....
Following is my selector that I use to bind the buttons to my click event:
<script
type
="text/javascript"
charset
="utf-8"
>
$(document).ready(function
() {
$('input[id^="btnUpdate"]'
).click(promptForSynchDate);
});
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes)
function promptForSynchDate() {
$(document).ready(
function () {
var test1 = $(this).attr('id');
alert(
'test1 is : ' + test1);
$(
'#approve-synch').dialog({ .....

Is it possible to set an html element's (created through HTML DOM's createElement() method) 'onclick' attribute's value to a Javascript function which requires a parameter, passing a variable to it at the same time?
I have the following Javascript code:
var parentDiv = document.getElementById("subscribers");
var stubSpan = document.createElement("span");
stubSpan.id = "opentok_subscriber_" + stream.streamId;
stubSpan.onclick = showStreamInFullScreenMode(stream);
parentDiv.appendChild(stubSpan);
'stream' in the bolded line is a parameter variable of the function that the above code is in, and I'm trying to pass it to another function using an onclick event.

I'm finishing up the front-end of an events management application, but I'm running into a problem with my javascript.
Here's the scenario: I have the php application returning all event details into a JSON object.
The object structure looks like this:
Code:
Each event title listing on the calendar grid is assigned "#" plus the event's ID for it's link, just for testing purposes--no problems.
Eventually, I want the user to get a yui container (modal) with the event details, but when I add the onclick handler to the links, the id that gets passed for each of the links is the same, 60 (which is the ID of the last iteration in the loop).
Here is my code:
Code:
I've tried using the var keyword to localize the id, but that produced the same problem.

I am trying to use DOM to create a UI for editing info pulled from a database. The info pulled are the locations of a given company. So, company A might have 2 locations (address, city, zip), and this is the info I want to present.
The way I have it now I use dom to parse the returned XML file and display the location info for each location on a seperate line. At the end of each line I want a button that the user can click which will then replace the current line (just text) with 3 input boxes populated with the values for address, city, zip.
Another button (UPDATE) will then be used to call a function which will update the db with the new location information. This is all no problem, but the part I cannot fathom is how do I associate the "location id" (from the database) with the UPDATE button on a given line, so that when the UPDATE button is clicked the function it activates will know which location (ie row) in the db to update. Code:

I have a web page that tracks clicks on certain hyperlinks. I am using
attachEvent() to attach to the document onClick handler, for IE browsers.
It works fine, except that for about 1 out of every 6 clicks, I get 2 to 4
click events for a single click. I know this because each time the
hyperlink is clicked, I write a record to a MySQL database. I write the
record to the database by setting the SRC property of an IFRAME on the page,
to a tracking script.
If I look at the database, for 1 out of every 6 clicks, I see 2 to 4 records
for the same click event (occassionally as many as 6 records). They are at
least 1 second and at most 7 seconds apart from each other.

I need to pass the selected option of a <select> tag into a query
string, so that the page is reloaded with the selected option already
chosen. This will occur with the onclick() event hander, and the query
string will be processed using a server-side technology. I'm just not
sure how to word the "onclick" handler. Here's what I have:
<select id="StartMonth" name="StartMonth" onchange="location.href =
'thispage.cfm?StartMonth=_______'">
What is the correct wording to set the underlined portion to whatever
was selected? I know it has to be done with JavaScript, since the
decision is made on the client-side.

I'm seeing surprising behavior, consistent across Opera, Firefox, and IE.
An event handler is changing the value of an element, and there is apparently
no Change event being generated for the element. A simple illustration is,
make an INPUT element with an onchange; type in a new value, the Change
event handler is called. But make a button whose Click handler changes the
value, and the Change handler does not get called.
It appears that events are not generated while an event handler is running.
Can this be true?

How can I interrupt the enter key so it won't trigger unwanted events on my
web page? I have tried this:
var defaultEventHandler = obj.getEvent("onkeydown");
var myEventHandler = function(event){
if(event.keyCode==13){
alert(obj.getProperty("selection/index"));
}
else{
defaultEventHandler.call(this, event);
}
}
obj.setEvent("onkeydown", myEventHandler);
But it won't even enter the function.

I got following document:
When you click the main button, will one of the six images get a background image, and you can then press the image with the background image, and get your "reflextime".
But it won't work. When I press the image, were the new background image has shown, you can click on it and get your time - why?'

I try to add a function to be triggered also within an event (which already has a function). I coded it, unfortunatelly one line of the code should be different for IE and Moz. I try to find a common way without using a browser detector... Any ideea? The red line works for Mozilla, the blue one for IE:
function addFunc(){
var e = document.getElementsByTagName('*');
for(var i=0;i<e.length;i++){
if(e[i].getAttribute('onclick')||e[i].getAttribute('onclick')!=null){// Moz || IE
//var f = new Function(e[i].getAttribute('onclick'));
var f = e[i].getAttribute('onclick');
e[i].onclick=function(){f();otherFunction()}
}}} Code:

I modified a particular page in the following way:
I ran an init function on window.onload, which iterated thorugh the checkboxes on the page and assigned an event handler function - let's call it validate() to each checkbox.
I tested it in the big 5 browsers and ran into a strange issue in I.E. only -
let's say there are the following checkboxes code...
When I click on "box1" the function is not called. When check "box2" the function is called but by "box1", when I click on "box3" the function is called by "box2" and so forth...

I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.

I have a form with a text box. As you know, if a user has previously entered data into that text box from the same machine, then a dropdown list appears in the browser showing previously entered values. That's fine; however I have an OnKeyUp event on this box so if a user selects from the dropdown list then the event isn't triggered. Is there any way to recognise this action as an event? None of the normal event handlers appear to do it.

I am working on a project that takes links on a page (Not all, depends on if they are Merchandise links or partner links), and passes some parameters to a tracking js call.The problem is, I don't want to put 'onclicks" on every href as there could be a hundred on a page and many of the links are dynamically generated on the backend.So, I was thinking of creating a function that took in parameters from each of the links that are pressed. we have two links (there will be many more, but for an example sake).
<a href="somelink.html" id="linka">link a</a>
<javascript>
var cu = new Linktracker({
[code]...
Should I use just "bind" or "bindAsEventListener"?Since each link on the page is unique and will pass different values, what is the best way to do this without putting "onclicks" on every link?
