I have an external js file used by an html page but I want to use global variables defined in the html page in the js file. for example...
<html>
<head>
<SCRIPT type="text/javascript"
var test = "1";
</SCRIPT>
<SCRIPT type="text/javascript" src="jscript.js">
</SCRIPT>
</head>
So I have var test which is defined in my .html but my jscript.js also uses the variable. I am doing it this way because I have a lot of pages that are simular using the jscript.js functions but each page has different quantities and values of variables used.
How can I have global variables and global arrays whose value(s) can be modified and accessed by all the Javascript functions in my HTML document as well as by the HTML code?
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?
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++) {
function openWindow(windowName){ timeStamp = new Date(); var timeStamp = timeStamp.getTime(); document.getElementById(window).style.display = 'block' }
blahblahblah . . . openWindow('order'); // calls openWindow function and sets timeStamp variable. alert(timeStamp);
then I get error: timeStamp is undefined. Why? I defined it as a global variable within openWindow. Am I just doing this wrong?
I`m building a site with html and GIF files on one server and audio files on another. That means I have to use absolute references to the audio files.
Problem is, the site will probably dwell some day in other server(s), and may also use a different audio format. I like to be able to globally change url strings and suffixes of the referenced files.
I think I can`t use "base href" because relative references (to files that are on the local server) would be affected.
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.
Is there a way to "pass" an XMLHttpRequest object to the callback function for onreadystatechange? Or a way to access it from onreadystatechange? I would like to avoid the use of a global variable...
Example:
/* How do I get rid of this global variable? */ xmlHttp = new XMLHttpRequest();
function myFunc() { ... xmlHttp.onreadystatechange = myCallBack; ... }
function myCallBack() { if (xmlHttp.readyState != 4) { return; }
//document.write("Test"); //Declare arrays stats = new Array(6); statMods = new Array(6); /* //Populate stat and statMod arrays
[Code]...
without first calling the other function that actually assigns values, it still works. As I said, though, if I assign values outside that function, then it all falls apart.
I've googled this and found a few different explanations that (as a PHP developer) are making absolutely no sense to me. I'm a total beginner with Javascript (not just jQuery) so a little help would go a long
i am having two global variables and i m setting their values on calling some function. After setting the values, i call a function in an object ...
if MyHint is an object and i am calling the function in it, but i am getting the values of global variables as undefined in the function of object MyHint. Is there any way to access the value of the global variables.
I'm new to javascript, but I need help and really hoping for a reply. I was trying to find an answer in Google but no result. So I have two table containing images, at the beginning only first table is displayed. Then when one of the images in the first table is clicked, a second table should appear, and user should click one of the images on that table. And that image should replace the one that was clicked originally in the first table.
So the question is, when the user clicks an image in the second table, how do I know what was originally clicked in the first one? I tried to use global variable but that doesn't work.
I've got some text that I want to change what it says:(63%) on RRP (£80.00) The percentage value and RRP Price will change dependant on the product and its discount. All I want to change with jquery is the text:
I cannot findout how I can write to global variables in a a JQUERY function. <script type="text/javascript"> function checkusername (username ) { $.post("[URL]", { action: 5, username: username }, function(xml) { result = $("apot", xml).text(); //<-- this variable is not global... why ?? message = $("message", xml).text(); //<-- this variable is not global... why ?? alert(message); //<--here variables are shown ok alert(result); }); alert(message); //<--here variable is NULL !! alert(result); //<--here variable is NULL !! } </sctipt>
I'm having trouble letting functions I defined in jquery read javascript global variables I defined elsewhere.. for example I have a function defined within my jquery
$(document).ready(function(){ function performTabSlide() { // do something with currentPosition;
i have this problem in passing values to a variable in a jquery function.
i have a js variable that accepts a certain value and then i want to pass this variable in the jquery function.
For example, this is my script: var autoScrollBool = "true" var autoScroolInt = "10" (seconds) stepcarousel.setup({
[Code].....
i want to replace the value of autostep: {enable:true to enable: utoScrollBool(the variable i created) , when i tried to assign it as is, its not working.
I have an HTML page which loads another page inside an IFrame. Each of the two pages has its own javascript code.
I would like to be able to define one global variable which will be accessed from functions in both scripts. The variable must be single. That means that if a script in one of the pages changes it, the change will be seen by the scripts in the other page.
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 need help getting variables in an external js file to transfer to the html page that uses them. I have an html page that lists verses to memorize, which, when the mouse hovers over a particular verse, a small popup reveals the book reference for that verse, thus giving a check to see if the user has accurately referenced that verse for its source.
I have an external js file (VERSES.js) that houses the verses and popup references sequentially as elements in an array and then writes them to the html document. A simplifed version of what I am using, with only a few verses listed here as an example, and that works beautifully, is given below: Code:
Does anybody know how I can have a global variable in an HTML file? for instance, I have a fuction (called aFunction() here) and during a mousedown or up event the function is going to be called.
The third passing arugment or parameter is myGlobarVar. How can I make this work? since myGlobalVar is defined in a different block of javascript within the HTML file?
I have some JavaScript which is splitting out the different variable elements from the URL.Now, how do I set the internal variables?Then I want to set the variable ScriptHeading to be Change and the variable ScriptType to be NewThread.I keep finding all sorts of lovely code showing how to split out the various sections in many different ways, but I can't find anything on how to actually set these variables.
