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'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); :
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 want a page with a hyperlink that passes a variable to another 'pop-up' page (in this case a name, its just an example) and new pop-up page prints a message followed by the variable thats passed.
Here is the code as it is right now
<html> <head> <script language="javascript" type="text/javascript"> function popitup(a)
[Code]....
In short, I just want the pop-up page to print 'Hello there Toby' or whatever name I choose to pass across. The 'testpopup.html' url is just the initial webpage.
I have a vague idea of what might be going wrong but I have no idea what I should be doing instead. Here is what I'm trying to do: User inputs X and Y coordinates into form validate that they are numbers do a little bit of maths redirect to a php script with a single variable tacked onto the end of the url Here is the form code:
//part of a larger php script to make the form echo "<form name='gotoForm' onsubmit='return coordCalc()'> <fieldset> <legend>Go to Square</legend> X <input type='text' id='X' size='1' maxlength='3'/> Y <input type='text' id='Y' size='1' maxlength='3'/> <input type='submit' [Code]...
First off I didn't know whether to post this here or in the PHP section since it deals with both, but mostly JS. I have a PHP scraper that scrapes the job title, company name and location from a website and stores them in separate arrays. These values are then extracted out one at a time from the array and stored into a string, that is then passed to a Google Maps API.
I can make this successfully happen once, the thing is I need to do it multiple times. I have an idea on what I should do but don't really know how to implement it (correctly). The idea I had was to create a function in the JavaScript section that accepts three values from PHP. This function would be called in my PHP for loop that extracts the values from the array into a string. The thing that confuses me is that the Map function is called via <body onLoad="initialize()">. Here's the link to my code (http://pastebin.com/rTfzJM16)
I'm looking for some help, as I've been going crazy trying to wrap my head around the step I am missing here. I have a function that generates a table of predefined row/column size, and which sets each <td> element's ID to "x ,y" where x and y are the horizontal/vertical coordinates within the table. It's intended for use in running a simple game.What I'd like to do is take it one step further and have the script generate onclick assignments for each <td>, giving them all an onclick function with unique arguments defining the <td>'s grid location. My problem is that I can't figure out how to pass the variables defining the coordinates to the onclick function created in the loop, as an argument.The syntax I'm using for assigning the onclick function:PHP Code:
cell[countx].onclick = function() {clickTile(''+countx+','+county+'')}; Variables countx and county are local to the original function. Here it is in context: PHP Code:
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 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;
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 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 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");
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 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.
This probably seems pretty trivial to you experts but I just don't know why it doesn't work and would like a nudge in the right direction please.I have a sllide and fade that works great - no problems. I am firing it with a function call from the HTML like so;<a href='#' onClick='sfade('#s1'); return false;>as you see I am passing the div to be faded(and slid) as a variable. Works great. The receiving function is:
var str=''; function sfade(str){ $(str).slideFadeToggle(1000);
