Call A Php Function With Onclick Event?
Mar 23, 2011
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?

I have a button that I wish to call a predefined function (Go()) shown below, but, I wish part of the URL that is sent to the function be inputted by the user.
function Go(URL)
{
window.location = URL;
}
Here is the code I have for the button, but I am getting a syntax error. What do I need to do?
<input type="button" value="Duplicate" onclick="Go(CustomerMailingList-duplicate.asp?ID=<%=rs(strPrimaryKeyFieldRecordset)%>&CustNum=prompt('Enter New Cust #', '0')">

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 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:

Does anybody have an idea how to call CGI on a onclick event when link
is clicked. This is a sample that works in some situations but
sometimes new page loading is to fast.
<a href="http://www.google.com" onclick="new Image().src='http://
www.example.com/process.cgi?p=1'">

I'm using a script (with inner HTML), to swap currencies. My onClick event calls two scripts to change the content of two cells. It works fine in IE, but Firefox... Nothing. I've run firebug, the error returned is "illegal character".

I'm wanting a table cell click event to remove and replace the table it was clicked on, however I'm finding that as it's deleting the original table object the actual running event code is being replaced and the function is bailing.how I can call the delete/refresh function from outside the event's function scope?

I am trying to create an image viewer with javascript and CSS. Unfortunately however, the onclick events in my image tags seem to work every once in a while for a few page loads then for some reason they just stop working completely and seemingly for no reason at all (i.e. I dont change any code). I've been messing around with this for at least a couple of weeks now and cant figure it out, so it is time to hit up the forums.
Below is the code I am trying to use:
Code:
<div class="nav"><img src="images/downblue.png" name="down" height="20px" width="20px" onClick="down();" /></div>
<script type="text/javascript" language="JavaScript">
function down() {
[Code]....
there is also an onload part in this script that doesn't execute. If I put an actual alert statement in the onclick part of the tag that will execute.

I have a web page a lot of thumbnail images arranged in a table. I would like the user to be able to click on the thumbnail to open a window with a larger view of the image.
So I wrote a JS function to accept a URL as the argument and open a new pop-up window with the given parameters. I need this function to potentially run multiple times from multiple links (in this case images) on the same page. However, after the first time I click the link, the function runs, and I close the pop-up, the function will not run again if I click the same or another link on the page. If I refresh the page, the function will work once and then not again. Is there a buffer I need to clear or something to reset to allow multiple links to work?
I have tried the function call in a whole slew of ways. Here's my current code (I "..."'ed out the URLs for brevity):
<script type="text/javascript">
function zoomWindow(url)
{
zoomWindow=window.open(url,"", "toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=no, height=645px, width=550px");
[Code]....

I have an html input and when a button is clicked, that input's value is passed to a function. However, the value becomes undefined when execution gets inside the function despite NOT being undefined inside the event handler! See below code...

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]...

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).

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 need to make a $.post call on the beforeSend event of another $.ajax call.I read the documentation and I see that if the beforeSend return false the ajax call will be interrupt.So I made this code but doesn't work, because the real value of the beforesend function isn't true or false, is the value of the post.I have to do this because when you click on a link I need to verify before if you are able to do this via db permission of my webapp.I think you don't understand...This is the code:
$.ajax({
async: true,
beforeSend: function(){[code]....
});I see always the alert of success event, so the return of the beforesend is not correctly done.

One of the problems with IE's attachEvent is that "this" will still refer to the window, as opposed to the object that called the function. Example:
Code:
function alertName() {
alert(this);

I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.
The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.
I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.
Sample code (IE 8 on Windows 7 computer):
script:
HTML:
