Using A Loop Variable In Function Call?
Apr 6, 2011i'm having trouble with some of my codes.i've been trying to put variables in function calls parameters, but it just does not work.
for example, if I try to do sth like this:
Code:
//a function that creates page numbers based on number of pictures that can be shown on the page
function MenuBar() {
pageSpan = [document.createElement('span')];[code]....
when i try to run it, it won't work.what i'm trying to do is that every time the loop runs, the "onclick" event of the created span will be the value of the loops "x" variable -1, and the value of x variable.meaning, for every new span, the parameters in the showImage() function are different.
Code:
pageSpan[1].onclick = function () { showImages(0, 1) };
pageSpan[2].onclick = function () { showImages(1, 2) };
pageSpan[3].onclick = function () { showImages(2, 3) };
pageSpan[4].onclick = function () { showImages(3, 4) };
pageSpan[5].onclick = function () { showImages(4, 5) };

Declare A Variable Inside A Function - Returns White Space - Not Variable Value
Aug 17, 2010I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

View 8 Replies View RelatedUsing Onchange To Call PHP Include And Set Php Variable?
May 14, 2010I'm building a form in PHP. One of the fields needs to generate information based on another selected input. The first input is for "phase" and based on that I need to count how many entries there are in the database for that phase, then display posible positions(ie 1 per entry including the entry being edited/added). I know that this can't be done with only PHP.
I don't work with Javascript normally so I am struggling. I have read many similar topics, but can't find the answer I am looking for.
I thought that the solution could be to call an include file when a selection for phase is made, but I don't know how to pass the information to the PHP script.
I'd prefer not to have to reload the page or form.
Here's the code that I have so far:
Code:
<html>
<head>
<body>
<form action="edit-category.php?id=<?php echo $id; ?>" method="post"

Call A Variable From Pieced Together String?
Jun 23, 2011I'm sure it's just a syntax problem. You can ignore most of this function because most of it works. The part I'm asking about is the "coordinates" variable 4th line from the bottom. The "office3" variable is a dynamically populated office number. I have the office numbers all defined as variables somewhere else but since I can't just name the variables as numbers I had to put a $ in front of them. Basically I'm trying to call the office number variable, $1656 for example. So "coordinates" is meant to be equal to "$+the chosen office number".[code]...

JQuery :: Call Variable Number Of Times With Different Parameters?
Jun 17, 2011I have a function that I call a variable number of times and I need to know when the calls have *all* been completed. How would I build that? As I understand the deferreds, the $.when syntax is as follows:
$.when(dfrd_func1('a'), dfrd_func2('b'),
dfrd_func3('c')).done( function() {
console.log("All Done");} );
will send "All done" to the console once each of the functions are complete.
So, I have the *same* function that I need to call a variable number of times with different parameters, i.e. :
$.when(dfrd_func('a'), dfrd_func('b'), dfrd_func('c'), ...).done(function() {console.log("All Done")});
So, is my approach wrong? Is there some way to build an array of functions that could be executed?
Call Variable Content Via Image Maps And OnMouseOver?
Jun 14, 2010I'm developing a multi-layered diagram as a web-page. The layers show versions of a network as it grows, with various components. I have created an image map on each layer. At the side, there is a panel where I want to display info about each component as I mouse over each element.
As a test, I used getElementbyID and inner.Html with a Javascript called writeText to display text in the side panel. However, as there are 6 layers and 20 - 30 images on each layer, I don't want to embed the text in each image map as it will make updating content a hassle and long home page.My idea is to use the ID of each image map as a variable and call the associated content from a separate page (XML maybe?) by naming the content section the same as the ID of the image map. I need to write some script that would work something like:
onMouseOver="writeText(call content with name="imagemapID")

JQuery :: Cross-Browser On Variable Change Call Back
Jul 1, 2011I want to bind a hook to objects member variable change event i.e. lets say I have object:
var obj { var1 : 1,
var2 : 2,
var3 : 3
};
I want to call "Magical" function like this:
onVariableChange(obj, "var1", function(obj, varname, old, new) {
alert("Variable " + varname + " changed from " + old + " to " + new);});
And after this function call every time obj.var1 is set to some value have my callback function called
I found something in internet: [URL]. Its cool but:
-It is changing Object-s prototype
-It is not working under IE 5, 6, 7, 8, 9, 10, 11, 12....
I've changed it a little bit and instead of adding to Object class prototype I'm adding it as member to any object which needs this hook. But IE still doesn't work. Is there any known cross-browser solution for this? I remember there was a jQuery upcoming project which would allow users to bind object to form and by changing one other will change automatically I wonder whats that project name and how they change input value when object member value changed.
Function To Call A Function In All Child Frames
Oct 16, 2006I 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:
