Onclick Defined Variable - Print Variable Some Place In Document
May 28, 2007
i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

I am currently working with a cms system that doesnt keep within the correct name conventions (pre defined).Within a form, I simply want to set a date to todays date:
<script type="text/javascript">
function initdt(mf) {
var t = new Date;
[code]...
This works perfect on a form I create, but sadly I must use a form within a pre defined system that uses "01-date" Is there a way around this? A simple way of setting 01-date to t.getDate();

My site is run on wordpress, but I'd like to customise the menu so that if the user is logged in the menu displays "Logged In" and if they are not it displays "Log In".Normally I would just use an if statement in PHP to output the required html, but as I can't use PHP code in the menu item I need to use Javascript. :mad:So, the way I figured this would work is:1) PHP code in the header checks to see whether the user is logged in2) This code then outputs JS to define a variable (varCheckLogin)3) JS within the menu checks varCheckLogin and outputs the html i wantThis sounds good hopefully. :DUnfortunately this isn't working at the moment. The code I have is:HEADER: (I know this works as the variable is being output correctly in the source code)
<?php if (is_user_logged_in()) {
echo '<script type="text/javascript"> varLoginCheck = "Yes"; </script>';
} else {
[code]....

I've been writing a new layout for part of my web page.
The java script is not creating the list. When I check Firebug I get an error:
QuoteMovies[movctr] is undefined [Break On This Error] MovieList+= Movies[movctr][2]
If I take out the var MovieList and just have it print the text "MovieList" instead of the contents of MovieList the code tries to run. I'm not sure why it won't copy the content of the var MovieList.
Live test version of my movie page
Here is my code:
It's also weird that is says that Movie[] is undefined instead of Movie[][].

I've a picture gallery with the images stored as variables in a javascript file like this:
var a100image10 = new mypicture("album1/a100image10.jpg");
var a100image11 = new mypicture("album1/a100image11.jpg");
I've a "next" button to show those images (one by one) in a div with this code:
document.getElementById('image').innerHTML = "<img src=images/gallery/"+eval(album+"image"+next+".getPath()")+"></img>";
where the eval function returns the path of the pictures.This works fine! but in IE I get an error saying a100image12 not defined (and image13, image14, etc), because that image is not in the javascript file.So, how can I test in advance if a variable exists in the file?? Note that I take the name of the next picture based on the current one.I mean,I take the current picture from the div, lets say a100image10, I add one, and I try to look in the file for the variable a100image11.

Using a while loop in a function, I am trying to test an input character against a stored string of characters. I want the function to return the input character only if it is not in the stored string of characters. The code I've prepared is as follows:
<SCRIPT language = "JavaScript">
var storedLetters = 'sideways';
function requestLetters(aString)
{
var validLetter ='';
[Code]...
The code works fine if I remove it from the function wrapper but if the function is called I keep getting an error message that the variable validLetter is not defined. :confused: Can anyone see why this is the case?

I'm trying to select a class (.home) and an ID (#something) at the same time,
normally I'd use:
$(".home,#something")
but in this instance, the ID is already stored in a variable called "newpage" - I'm trying the following:
$(newpage,".home")
(note, selecting the id on it's own with just$(newpage) does work, so I know the issue isn't with my variable, it's just a matter getting both the class and the variable stored ID selected at the same time)

I've got this:
Code:
var noteCount = "";
jsonRequest('media.getFiles', params,
function(result) { noteCount = result['totalCount']},
function(exception) { noteCount = "0"},
true
);
The console returns results['totalCount'] with a value of 2 (that's correct).
When I call noteCount for display, it shows nothing. Neither the var set by result or exception.

In the function 'formToArray' the variable 'max' is causing a conflict in my application. The reason being that max is not explicitly defined as a var so it becomes a global variable.So IMHO:
#520 - var i,j,n,v,el;
for(i=0, max=els.length; i < max; i++) {
should be changed to
#520 - var i,j,n,v,el, max;
for(i=0, max=els.length; i < max; i++) {

I have a function that takes parameters of what the form name and the form object name is and then modifies the form accordingly. Now I can make it work fine if i make a separate function for each form object, but that seems very cumbersome. This is what I have
document.formName.formCat.selectedIndex;
i want formName and formCat to be variables so I can specify in the parameters which part of the form to deal with, but i get an erorr. Is this possible?

Basically, I have a form with some text fields, and I want to put a button next to each text field, so that when a user clicks on the button, it increments the value in the field by 1. I know how to do it if I know the id of the text field, but what if the id of the text field is a variable? How do I do it? Here's my code:
<script language=javascript>
function process(v){
document.getElementById('order_item' + v + '_quantity').value++;
[code]....
My issue is with my onclick statement:
<input type="button" value="Add +" onclick="javascript:process(0)">
This works fine for my first field, but I need to have one for every text field, so how do I pass my counter variable (which determines the id of the appropriate text field) to the process function?

I am building a site where I want all links to partial page reload using xmlhttprequest and innerhtml. I have done this before, butI always had to have a seperate xmlhttprequest function for each link. So this time I am trying to write just one function, and have the onClick change which document the request is getting. It is not working and I appear to novice to figure out why. Here is the code, i have bolded some relevant lines:
<script type="text/javascript">
function ChangeContent()
{
var whichPHP;
[Code]....
Also, if I use the innerhtml function to write another of these hrefs, will that link be able to access the function if it is in the header, or should I put the entire function in a .js file on the server? The point of all this would be that the entire page never reloads and all the text content is swapped out on demand.

I am trying to use an onclick statement to go to an alternate web page displaying a different version of tha file being displayed in the current page.
In the HEAD section of the current page I have a global variable named currentfile that contains a file name. This function is also in the HEAD section immediately below the variable's declaration
I have tried every combination I can think of in the onclick code to get it to work but, no joy. here is an example:
I just can't get the next page to load.

I have a form, that when the user click Submit, I need a php variable to be echoed to the page. This is for an upload page. So when they are waiting for the file to upload, it will say "Uploading..." until the upload is complete.
All I know so far is I need to create a javascript function and include it in the submit button. This is all I have so far in the submit button tag:
onClick="Transferring();"
