I'm trying to pupulate a web page with javascript. I have 2 functions. One that runs on-load so I can populate a dropdown list. The second one to process the selection when the user selects an item from the list. I have a global variable in the top of my javascript that I use in the functions and as long as I set it in it's global scope, everything works fine. But what I really want to do is to pass this into the javascript running on this page via [URL]
I cannot get this to work. First here is what I have that works:
<script type="text/javascript">
weekNumber = "00"
function processSelection(sel) {.....
... [includes references to weekNumber]
.....}
I've got the code to gets the variable passed in properly:
var sGet = document.location.search;
sGet = sGet.substring(1); // Eliminate the leading "?"
var sGetPairs = sGet.split("&") //Get 1st pair
var sGetValue = sGetPairs[0].split("="); //Split it
var weekNumber= sGetValue[1]; //Save it
Where do I put this code so that I can use it to set the global variable "weekNumber"? I've tried putting this code in the populateList function. I've tried referencing it via window.weekNumber and this.weekNumber. I've spent far too many hours trying to understand this without success. Where to put this code so I can set the global variable weekNumber?
I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;
However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?
Here is the code for displayResults(imageArray); :
I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.
If I have a global variable in one <SCRIPT>...</script>, is it available in the 2nd <SCRIPT>...</script>. I do not know if "global" means the whole document or the whole <SCRIPT>...</script> only.
i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long
I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.This piece of code is working well . . . .
<?php
$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error()); mysql_select_db('mydatabase') or die('Could not select database');[code]......
I've created a site where the pages generally contain a table of contents (site map) down the left side. When each page loads, the first function is called. The second function populates a global var (array) of all the links.
I try to avoid using global variables, but I am stumped how to eliminate this one (TocLinks) because other functions need to iterate through it. I think the answer is to create a custom object that the other functions can access. But I need some pointers on how to proceed.
Here's the function that the pages call initially and the 2nd function that it calls:
I have a global variable which does not want to change : <header> .... <script type="text/javascript" language="JavaScript"> var i=1; function swap() { var window.i = 1 - window.i ; } ..... </script> .... <body>
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 a site that calls the function welcome() and displays a prompt. The same site also has an iframe that calls the next function, add_name(), but when the pages are loaded it says that "answer" is undefined.It says on the page, where the <p id="guest"></p> is, "Welcome undefined". How do I make it so that the value of answer, which is given onLoad of the 1st page with the prompt, is displayed as text in function add_name()?
[CODE] function welcome(){ var x = document.getElementById("body");
The value of startTime when called from display() is undefined. I'm not sure why, as I declared the variable outside the function. The variable should be accessible by all functions, right?
I have two pages. In one page I am changing the value of a variable called t, in the other I am outputting it. The problem I'm having is in changing its value.
I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: [url]
I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below:
1.How can I have the Jukebox cycle through all tunes and then start over from the beginning?
2.How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the users selection and then play all songs to the end. Then as in #1, start over from the beginning?
Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a playlist from the drop down.
Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to.
The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.

Jukebox utilizing an .m3u playlist:
Here is the .m3u playlist for the above code:
The following code is for the Jukebox that has a list of links in a dropdown list. If I go with this idea, I would like for the list not to be a dropdown list but just a list of tunes. The user should be able to click on any tune in the list and the player should start from that point, play all the remaining tunes in the list and then start from the beginning.

Another idea I found on the WEB also uses an .m3u playlist. The good thing about it is that it lists all the tunes in the playlist which the user can then select from. This jukebox calls up an entire Windows Media Player. If I was to use this idea I would like to be able to disable the left side of the player where the user has options such as burning to CD, Media Guide, Radio Tuner etc¦

I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?
function changePreference(pos,mt){ //mt does not reference mech2Num, I need it to. } changePreference(2,'my' + pos + 'Num');
var mech1Num=1|2|3|4|5|6; var mech2Num=1|2|3|4|5|6; var mech3Num=1|2|3|4|5|6;
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?
use this kind of syntax in an open source plugin.#varableName = someMethod(); that someMethod return an object instance.Then I can access that object outside that plugin. Is this a standard javascript global variable or some jQuery feature?

My question is. Where do I put this code so that I can use it to set the global variable "weekNumber"?
I've tried putting this code in the populateList function - NOPE! I've tried referencing it via window.weekNumber and this.weekNumber - NOPE. I'm stumped.
I've spent far too many hours trying to understand this without success. Can anyone help me figure out where to put this code so I can set the global variable weekNumber?
I have defined a global variable for a form, but it seems my functions can't access it. The error I get from the Firefox Javascript console tells me that my variable has no properties. Code:
var giftForm = document.forms.uploadGift;
function sendForm() { giftForm.target = 'main' giftForm.submit(); window.close(); }
Everything runs without a hitch if I declare the form variable inside the function.
The first time I enter the command n it should run the first if statement, when I enter n it should then run the second one as its in zone two. However this is just not happening..

I would like to store a variable then call it back later. I have a variable on line 198 www = ''+this._ad.clickUrl+''; And on line 321 I try document.write(www); I've tried so many different options, just won't work. I have even tried to call document.write(window.www);

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.
