Use A Variable Inside A CDATA Block?
Feb 3, 2011
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.

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'm receiving XML data via AJAX and the XML includes some CDATA values. The XML needs to be added to the page and then later scraped from the page and sent back as XML via AJAX.
Simple Example:
I receive -
And want to end up with:
And then send back as XML
99% of this is easy except the handling of the CDATA tag.
If I treat the XML as HTML, the CDATA tags get commented out automatically by JQuery.
So .html() returns <!--<![CDATA[Hello World]]>--> and .text() returns an null value (which is correct for a node containing only a comment).
If I treat the XML as XML, then .html() doesn't work making it impossible to insert the data (with its XML tags) into my page.
The only way around this I can see is to create a function that loops through the XML creating a HTML duplicate somehow and converting the CDATA nodes. When I want to send it back I have to reverse the process.
This seems a very long winded process when all I want to do is treat the XML as HTML except for the CDATA which needs to converted appropriately.
So two questions:
1) Am I missing some easy way to do all this using JQuery or other tools?
2) If I do need to manually convert the XML into HTML and vice versa, how do I do it?

I have an XML document that is returned which has an element named html. Inside of that element is a block of HTML wrapped with CDATA tags. I can alert the html variable that i create and see it has all of the data inside of it. So I want to parse through and grab certain things now. I'm just trying to get the element to return it's id to me, even though I know it ... because I kept getting the following error with other code.[code]

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?

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'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.

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?
