Access A Sub Function From An Onclick Event?
Oct 11, 2011
I am working a project for school in which I am trying to make a simple math game. When the user clicks the start button it will bring display a question and ask for an answer. What I want to to is when the user clicks the start button it will swap the button for to other buttons to move to the next question and one to restart the game. Which works fine, the problem is after the buttons are swapped.
How would I access a sub function from a buttons onclick event? I currently have onclick="return MathGame.resetForm();" but that throws an exception and I can't see where. What is the best way to go about this. Also this is my first attempt at using javascript in this manner so I'm probably going about it the wrong way.[code]...

I have this script
Code HTML4Strict:
<head>
<style type="text/css">
.correct_field
[Code]....
Which does not work, what I am trying to acomplish is set the class of an object, if I do the whole thing inside a function it all works, however if I create another function that calls a second function it does not, how could I use the object that fired the event in the numbers() function?

I have a small portal website with some ads around. I'm in the process of creating an ads manager script with php and mysql and would like to know when an ad was clicked. I'm confused on how to do this but, the only way I can think of is by adding an onclick even to every ad img:
HTML Code:
<a onclick="callfunction('ad_id');" href="ad url"><img src="path"></a>
Now, how would I call a php function with onclick? I guess that can be done with ajax but, don't know much on how to use it?

The following coding works in Konqueror 3.5.10 on Ubuntu 8.04.3 LTS but not on Firefox 3.0.10 Linux/3.5.7 XP, Opera 10.10 Linux or IE8 XP.I can't see why but it may be to do with the recursion (showtable calls onclick calls addit which calls showtable).Somehow it is not seeing the addit routine the second time round.It is meant just to add a line. Eventually it needs to be a complex table but this is for illustration. There are other ways to solve this but this would be the simplest - if it worked!What happens is that one line is added OK but then it chokes. This is what makes me think it is the recursion but I can't see otherwise how to make it write the updated text. I realise I should have a document.close() in it as well and I have tried adding <![CDATA[ ... ]]> as well.Other than in Konqueror, it gives an error message saying object not found (in IE8) or more explicitly:[code]

Does anyone know how to create a link (<a> . . . </a>) with some piece
of javascript code that has the onClick event set for some function that I also wrote (not a build-in function).
I can find all sorts of samples in these disc.groups but none of them
seems to work for me.
I am focussed on Firefox, but some code that also works for IE, would
be appreciated.
BTW I know how to create elements in the html document, that is not the
problem. The problem is that I seem not te be able to set the onClick event for some created element. I tried for both a link and also for a text-element.
I can set the onClick for some built-in function like alert('Nice Day').
There are loads of examples to be found for that, and they indeed work.

I need to run a PHP function call through an onClick which through my research I have found that I need to use AJAX. Let me explain better what I am trying to do. I am currently using Simplepie PHP to pull various RSS feeds, I have an HTML DIV tag that loads the titles of the feeds and I want to get to the point where each title is clickable (im assuming this is through onClick) to run a simplepie PHP function to pull the content into a seperate DIV (on the same page).

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.

What I need is simple. Here I created 3 links and after that I want to add dinamically an onclick event to alert the number of the link. The problem is I can't find the way to pass the variable.Obviouslly this is not the actual function, but I need to solve this problem to apply the solution into a more complex script.

I have a few buttons on a page I'm developing and I want the onclick event to call a javascript function in an external file and execute it. I would like to be able to pass a parameter to that function and then either have the function take the user to a new URL or make changes to the webpage content.
Initially (just to test) I had inline javascript that caused an alert to popup. That worked fine. Next I took the inline code and put it in a function in an external javascript file that was referenced in the HTML:

I want to make it so that when I click on something, it changes what document.onclick does.
This is a simplified version of what I'm trying to do:
Code:
<div id="clickme" onclick="document.onclick = function(){ alert ('This should not be alerted on the first click'); }">Click here</div>
However, as you'll notice, the alert box shows up on the first click as well. The only way I have been able to get around this behaviour is to have the first onclick execute a timer that will then set the document.onclick after 1ms, however this seems very messy to me.

currently on our site we have and expanding <div> that responds to both the onmouseover and onmouseout events. It works wonderfully.
The UX people now would like the expanding <div> to open with the onclick event and then as soon as the mouse leaves the expanded div, it would close. I have tried using the onmouseout event in conjunction the onclick event but it does not work (the div persists).

I have a JS method register in a TD element as below:
Below is the Js Method:
The JS method works fine in IE but in mozilla throws an error that event is undefined.
I cant pass the event object from HTML while registering the method as HTML is written by someone else and I cannot change that. All I can change is the JS method.
How can i access the event object in JS method.

I have code which is created from a content mamagement system. It places
some handlers on tags with in-line registration:
<tag... onmousedown="mousedownHandler(this);" ...>
I want to modified the handler and access the event. Here's an example of
such (very contrived example):
fucntion mousedownHandler(obj) {
if (!e) e = window.event;
this.style.top = e.clientY +'px'
}
This works in Safari as it knows the event as e and I can get it for M$IE
with the window.event. How do I go about accessing it in Firefox?

If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like:
remoteWindow.onload = goToPage(url);

I've worked with them on many occasions, but my question if an HTML tag currently has an onclick event and I need to add another, can I just simply add another onclick? Example
<a href="/files/Registration_Form.doc" onClick="javascript: pageTracker._trackPageview('/downloads/Registration_Form_Universal'); onclick="javascript:this.form-just a sample">here</a>

My name is juan and recently started html programming. I have a web page with a drop box with the name of states.
<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.
<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?
