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);

View 2 Replies View RelatedHow do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!
View 16 Replies View RelatedI 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?

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.

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 was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
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.
I have a dinky ajaxSubmit plugin which causes a form submit action to submit that form via AJAX along w/ some validation. Currently, in a global.js file which is included by every page, I have:
$(function() {
$("form.ajaxsubmit").ajaxSubmti();
});
Sort of a global onload event. The plugin uses the live() method to bind so that future forms added via any callbacks would be wired up as well. Question is: is this a best practice w/ jQuery? Is there a better way to wire up plug-ins for DOM events w/o using this sorta global onload event?
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):

I have a .js file that receives a value from an html page. I'd like this
value to be a global variable that all functions in the .js file can use. I
have tried just declaring a var at the top of my .js file, but when the
value comes into the function and gets assigned to that variable, it is not
global.
I have been working on a function which makes it easier for me to pull
variables from the URL. So far I have:
<script language="JavaScript">
var variablesInUrl;
var vArray = new Array();
function loadUrlVariables()
{
varString = location.search;
//removes ? from varString
varString = varString.substring(1,varString.length);
//split into array containing variable=value
variableArray = varString.split('&');
variablesInUrl = variableArray.length-1
for (i=0; i<= variablesInUrl ; i++)
{ ....
