Declare Variables Once And Use Them In Multiple HTML Files?
Jan 7, 2011
I have been working on a few budget scripts that I can access from the web in using HTML. My problem is that when variable values change I need to change these values in all of the HTML files on the server. I know that there is a way to declare global variables in a single file and use those values in another file but I have not been able to find any information that tells me exactly how to do this. I have tried to put it together on my own using what little informaiton I have been able to find but have not been able to get this to work. Is there a more detailed referance that I can find somewhere or does anyone know what steps I need to take to make this happen?

What is the correct way to work with multiple language JavaScript files? So how to use your PHP language variables in your JavaScript files? The way I do it now is create JavaScript files like 'script_js.php' like this:

I prefer to keep all my scripts in an external '.js' file. I am currently loading the external '.js' file from the header. Problem is I would like to declare a global variable in the external file, but I keep getting an error about the object does not exist.
Can someone tell me where or how to declare a global variable in an external file that is available after the page is loaded.

can anybody put forward a sensible argument javascript's behaviour of
creating a new global variable whenever I assign to a previously undeclared
variable. I can't beleive this is just for the sake of convenience (surely
we learned this much from basic).
here's my proposal: all "global" (document scope) variables must be declared
by 'var' outside a function block.
failing that, does anyone know any patterns or tricks I can use to make sure
I don't create a new global variable when I accidentally misspell a variable
name?

I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.

I am familiar with the user built addEvent function used to load multiple functions in the window.onload property. However, I am curious as to the best way to do this across multiple JavaScript files. I thought I had seen somewhere code similar to the addEvent function was native to JavaScript now but I can't seem to find that anywhere.
Just to clarify, suppose I have 3 JavaScript files:
Code:
function foo() {
// do something here
}
fileB
[Code]....
note that it is not feasible to combine those functions into one file as they aren't always loaded together. What's the best way to load them all as a window.load?

I would like to use a compiler to minifier my JS code. The JS code is separated over multiple files. For example, I have a language file (lang object), init.js files, common function files, ... here and there I even use global variables. I would like to use a compiler which also renames variable names to reduce JS file size. However, when the variables are separated over multiple JS files, and you compile each JS file one by one, the same short variable names will be attached given errors in the whole application.

Is there a way I can use JavaScript to compile a list of checkboxes with the value of the url of the file I wish to upload from my computer.And then with that checklist PHP can grab the files from my computer and upload them to the server. Doesn't have the be checkboxes but basically a list of locations so the files can be uploaded one after another. Much like Facebook's ability to upload multiple files. I can't find out how to select multiple files, so I figured just compile a list.

Im building a simple portfolio site for myself and I am trying to use the .hide() and .show() methods to hide and show the various sections and subsections. I have one file panels.js which is working fine on its own to hide and show the main sections. But a second file gallery.js, which is supposed to control the subsections, never gets read. I can see the contents of the file in firebug, but nothing inside gets executed. If I take the contents of gallery.js and try to place them into the panels.js file. the whole thing stops working. So Im assuming its something off with the scripts in gallery.js. Heres the site so far: [URL]
At this point I am only working on the "ARTWORK" section, so that is the only section that should be working, please don't bother clicking on the other sections. What should be happening is that all the entries that say "Image Title" with some lorem ipsum should all be hidden at first, and only the first sentence at the top should show, but at this point all of it just stacks up and none of it is hidden. heres the contents of gallery.js
//hide all the subsections and show the intro
$(".current_panel .image_area").removeClass("current_area");
$(".current_panel .image_area").hide();
[code]....

I have a simple FLV player that I would like to use in an online video store. I would like it set up so that every time a user clicks on a video to preview, the video plays in the player that will be on the side. How can I set this up so that the player will play an opening video when one enters the site, and then whenever someone clicks a video, it will play in the same player without loading a new page. Can someone show me how to do this using Javascript?

As I use some external js library and code (swfobject, jquery, fancyzoom, ...) and that, having alot of file requested can slow down a site, I want to know if it is a good idea to merge all those js file into a big one, so it is loaded 1 time, then is in cache. I think it can be good for server request but, is there any bug possibilities to do this?

The application I'm debugging is throwing a very general jquery error (H is undefined) based on my obfuscated js file. There are jquery methods in this file. The file has been tested and is used successfully in other applications. I noticed the application that throws the error is loading two versions of jquery:
jquery-1.4.2.js and jquery-obf-1.4.2.cache.js
Typically our applications only load the obfuscated version of jquery. if loading 2 versions of JQuery into a page could cause the confliction I'm seeing?

I was on HTMLDrive.net looking for some cool effects for my site, and when I tried to put two of them in a page together it would not work properly. I can get only one to work at a time. It seems that they somehow interfere with each other, but I don't know how. Now have a little experience with JavaScript and jquery, but nothing I tried would work. Here is what I have in my page header right now:
[Code]...
The first one is an accordion navigation panel and it comes with a JavaScript file to link to in the header. Other than that there is no more JavaScript involved with it. Here is the link to it: Accordion Navigation The other one is a image slide show that uses jquery. it has the jquery script, a script file of it own, and some JavaScript right in the page header. Here is the link to this one:

This is an example of an html page I am trying to create.
When it is run "as is" (with the function subCall in a .js file in the same directory as the .html file, only the first alert shows. But, comment that line out and uncomment the function definition, it works file.
Of course, this works locally, but when I put it onto the server, it doesn't.
I'm new to scripting so I'm hoping there is an easy fix to this. Code:

Does anybody knows a good jQuery multiple file uploader? The idea is when somebody click on the Upload link some kind of popup box needs to appear. Something like the media uploader in WordPress. The background of the website becomes grey, and only a upload box appear. It would be cool that only if you have selected one file, the next input for a new upload appear with a max of 9 uploads at a time ...
