Calling A Variable Inside A Command?
Mar 31, 2010
im not sure now to word it, or how to do it, im a php coder not a javascript -.-but here it is, basicly i have one ajax file and wish to use it for everypage,i tryed to do it so i can just call one function for all ajax uses, but forms seem to be thowing me off when i call it, i stat if its a form or a element,
function ajax(str, b, c) {
a = b;
type = c;
if (type === 'form') {
[code].....
in this, the variable a is set as the id of the elemnt/form, it works fine for elemnts, but not for forms,i think this is because its thinking a is the id, not the variable,

I have an embarrassingly similar problem to the last time I was here. I have a google map that generates links and checkboxes from an xml file and puts them in a sidebar. The links open infowindows and the checkboxes show or hide lines on the map.
Which all works ok. But (like last time) I have another function that puts arrowheads along those lines to indicate directionality.
The code which turns the lines off and on looks like this:
function togglePoly(poly_num) {
if (document.getElementById('poly'+poly_num)) {
if (document.getElementById('poly'+poly_num).checked) {
gpolys[poly_num].show();
[Code]...

consider the next code:
var obj = {};
with(obj) {
var x = 10;
}
print(x);
print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the
value 10. But it's not the case, because variable declarations are
placed at the start of function code (or global code), so the
previous code is equivalent with:
var obj;
var x;
obj = {};
with(obj) {
x = 10;
}
print(x);
print(obj.x);
You can clearly see now that x is placed in the outer context. But
consider the next:
var obj = {};
with(obj) {
eval("var x = 10;");
}
print(x);
print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it
gives the same output as the previous code. I tested it with
spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could
not find anything that describes that behaviour. Code:

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

i guess this isn't really jQuery specific rather than it is a global JS-thing, but I tried general solutions for this and they all did not work so I figured this might be because I'm trying to do this with the $ function.
What I wanna do is this: I have a document with an iFrame. From inside that iFrame I wanna call the $-function of the original (parent) document. I tried so many things like
parent.$
top.$
window.parent / top.$
the stuff above with .document.$
and other stuff but none of that works. So, how do you call $ of the real document from inside an iFrame?

I have a huge form with a lot of data.
There is a table that data in it I need to display on a print screen (of course this data isn't being displayed in the regular table).
So, I put the display text in a span tag.
So, this is how each item will look:
I need a way to grab all spans on the page that have the attributte of "printData" and grab that text inside that attribute and print it out.

This is probably more of a basic javascript question than a specificjquery function.I have this jQuery function named validateSubmit()which calls two other regular javascript functions. When using IE,both createCharts() and getDirectorIDs get called but when usingFireFox, only createCharts() gets called and never makes it togetDirectorIDs() and I'm not sure why this occurs.
<script type="text/javascript">
// make sure at least one checkbox is checked
function validateSubmit() {

I am calling a program using $.getJSON() inside of a for loop. The problem is that the second callback doesn't wait for the first program to finish before it executes. Is it possible to ensure that the second iteration of the loop doesn't happen until the first one is finished?
$('#dialog-form').dialog({
buttons: {
"Import": function() {
var ids = $("#itemsGrid").jqGrid('getGridParam','selarrrow');

I am trying to call a function from a link or button like the example below, however I would like to call the function whilst passing a variable along (not a string).
This isn't my code, it is a simple way of explaining what I am trying to do.
<html>
<head>
<script type="text/javascript">
function myfunction(txt){
[Code]....
So instead of 'java too!' I would have a variable named "category" which could contain different data each time the button is pressed.

I am using a javafunction (onclick in select) in which i am calling a
function in php (thats why i send this to both php and javascript
newsgroups).
in the onclick i call the function "Place_Selected" with the value from the
select (naam_keuze.value)
in the function the value becomes the $zoek_id and searches in the database
for the record with the id of $zoek_id
the naam_keuze.value does not give the value to $zoek_id When i replace naam_keuze.value for a number (15) i works great.
WHAT AM I DOING WRONG? Code:

The code below is the relevant part to an autosuggest feature. The variable that isn't being passed is "firstValidIndex". It is being set appropriately, but when it is used in "sortArray()", its value is 0.
// here we must check to see if where the string matched was at the beginning of a string inside this.aNames
// firstValidIndex is the first index where the char is at the beginning of a string

I've looked extensively for the answer to this but suspect my inexperience means I'm using the wrong "keywords" in searches, or the answer involves jquery beyond my comprehension.
I have script experience and have plug-in galleryView working but have no jQuery experience which is the problem.
The script:
<script type="text/javascript">
name
= getValue("name");
$(document).ready(function(){
[Code]....
Variable name contains data stripped from the page URL (www.url.com?name=3). I want to use this variable in the jquery array/list passed into the galleryView instead of the number 3. How can this be achieved? I suspect this could be done entirely in jquery (if I had the experience) or via the getdata script used above?

I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?
* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global
* A local variable that is declared inside a function is local to the
whole function, regardless of where it is declared, e.g.:
function blah() {
for(var i ... ) {
var j ...
}}
i and j will both be visible within blah() after their declaration.
* the notion of "function" in this context also applies for this kind
of construct:
var myHandler =
{
onClickDo: function()
{
in the sense that whatever one declares inside onClickDo with "var"
will only be visible inside onClickDo. What else, am I missing anything?

I'm using the following to sequentially change the background color of some list items. It works, but is there a direct way of putting a variable inside the n-th child parentheses, instead of concatenating? Second question, more CSSey, though. The highlight goes all the way across the page since the CSS bounding box is 100% for the li items. The lines are various lengths so I can't just set the bounding box to, say, fifty percent. Is there a way to use jQuery to make the bounding box, or background color only go to the end of the text?

I'm making a project which creates tabs with a class. I don't really know how to explain it better but this is how it works:
<a href="#" id="tbs_tabs">Create</a>
<script type="text/javascript">
var tbs = new Tabs('tbs_tabs');
tbs.theme = 'classic'
tbs.create_option('abc','#');
tbs.create_option('abz','#');
tbs.create_option('abf','#');
tbs.create();
</script>
It first creates the new class and tells it the id, then it creates as many options as you want and creates it.
My problem is with this line:
for(i=0;i<this.option_values.length;i++)
{
li = document.createElement("LI");
li.appendChild(document.createTextNode(this.option_values[i]));
addEvent(li,"click",function(){oThis.select_option(i); return false;};
ul.appendChild(li);
}
What I was trying to do here is add an event to the LI element that refers to the current tab class but doesn't use the CURRENT i value but the value that was when the event was first created.
For example.. If my i value is currently 2 and I add the function, then I want that when I call the function, the value will still be 2 and not the current i value. What happens now is when I call the function the value is something like 5 or 6.

CDATA-blocks work great for coding large blocks of HTML, or CSS, into strings. But, I can't figure out how to use a variable-value within one.For example, consider this JavaScript code:
var FullName = "Friedrich Hayek";
var ProfileCode = (<><![CDATA[
<div id="BigHonkingChunkO_HTML">
[code]...
How do I get $FullName$ to render as "Friedrich Hayek" instead of "$FullName$"? Note that there is more than one variable and each variable can be used a few times in the CDATA block. Alternate code sample:
var UserColorPref = "red";
var UI_CSS = (<><![CDATA[
body {
[code]....
Looking to set the color attribute to red.

I have a set or icons that which over time I replace with a different icon and and add a onclick event to them. This is my code
function updateStatusIcons(retText) {
updatingStatuses = true;
var updates = retText.split("|");
for (z=0; z<updates.length; z++) {
[Code]....
Everything works fine except for the onclick event. In the hover message of the icon, the correct project ID is displayed in the message, hoever in the function, the onclick funtion always loads the page with the last set project id. How can I pass the project id into the onclick function and make it stay fixed and not be the value of that it was last set to?
