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?
View 1 RepliesIs there a way to call a javascript function in a meta refresh statement? I'm refreshing my page but if I have data in my fields I don't want to loose them. If I can call using a JS function then in that function I can call the Submit function and save my data in the called script.
My syntax below doesn't fire the JS function:
<meta http-equiv="refresh" content="30;url=javascript:auto_refresh();">
I have this javascript code which I would like to call the refresh method in my init function but I can't seems to be able to call it. What is the proper way of doing this?

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 try to make something where you add elements, and can delete elements later by calling a simple function. I simplyfied it right here: It works only to add the paragraphs, but the delete function doesn't work. Tried already to debug with an alert message after each rule... but the problem is with this rule I guess:

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:

I can't use the value returned by $.post() method out of the scope of success function.
For instance in below example myvar alerted as empty even though var is alerted with a value. Besides, hide does not work in the scope of success function.
<button onClick="return popup('<span onClick='selectShape(1, 1, 1)'>test<span>');" tabindex=Ɖ' onFocus="setFocusColor(0,3)">....</button>
This will work perfectly, but as soon as I need to pass Strings inside the selectShape function, I get stuck.
So the question is, how can I create the following and have it working

I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?
* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global
* A local variable that is declared inside a function is local to the
whole function, regardless of where it is declared, e.g.:
function blah() {
for(var i ... ) {
var j ...
}}
i and j will both be visible within blah() after their declaration.
* the notion of "function" in this context also applies for this kind
of construct:
var myHandler =
{
onClickDo: function()
{
in the sense that whatever one declares inside onClickDo with "var"
will only be visible inside onClickDo. What else, am I missing anything?

View 2 Replies View RelatedI'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.
I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.
I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

Not sure if this is possible, but I have an external script that creates an object, and I want to overwrite some of its functionality, but keep the scope.
Here is a basic example:
Code:
<script>
Obj = function (userConfig) {
this._init(userConfig);
[Code]....
I want it to log two Objects, but instead I get two window elements. Is this because I am declaring the functions in the global scope, and not from within the object?
Anyway I can keep the scope of the object, whilst still overwriting the function?
I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.Why is an object reference assigned to what was previously a string?
View 6 Replies View RelatedOne 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:

I have a document that can contain any number of iframes which have
further copies of the same document (and so on). In practice, we
shouldn't ever have frames within frames, but I'd like to make the
implementation a general case.
Various of the functions in the parent document need to call themselves
in the child documents with the same parameters as they've just been
passed.
Now, I can stick a loop in each function that goes throught the
window.frames array and calls the function for each frame, but for I'd
like to write a function to do this.
It's at this point that my brain explodes. If I limit it to a single
parameter we can do:
I'm in the middle of a JavaScript class, and I've run into a problem with one assignment. ^^; I've been given a pre-written script and HTML code to work with, and am required to modify it. Here's one thing I have to do, via my instructor:
Add an "email" field to this form. This field should also validate as a valid email address. (Hint: after adding the form field to the form itself, your next step will be to expand the function named submitIt() by adding a second if statement to confirm the contents of the email field. You will want to paste into the header and use the validEmail() function which you will find in Script 7.15, highlighted in red on pages 192-3 of your textbook.)
I know how to write the code to validate an email address, but I can't figure out how to call the validEmail() function in the submitIt() function. The code I have now just blanks out all the fields when I hit "submit." Here's the part of the script with the email validation:
window.onload = loadDoc;
function loadDoc() {
resetForm(document.forms[0]);

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic.Now for the problem:When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page".
