JQuery :: Put A Variable Inside The N-th Child?
Jan 18, 2010
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?

What is the syntax for accessing the children of a class, where the class is a variable?The html structure is multiple divs like this:
<div class="class1 class2 class3">
<p class="x"> lorem</p>
<p class="y"> ipsum</p>
<p class="z"> yadda</p>
</div>
(There's a structural reason for accessing the child <p> tags, rather than just the parent <div>s. Some <p> tags in some<div>swill have previously had a style change applied: if the changes are now applied only to the parents, some children won't change… at least not till they're hidden).Anyway: this code doesn't work, doesn't generate a FF error message, and doesn't stop subsequent chained functions from operating. So it can't be far off; and the syntax$(cl + ' > p') works ok in another function.

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 looking for a way to get a variable from a parent window in a child window. I'm aware that you can write the variable to a hidden field and then get the field's value in the child window, but I'm looking for a cleaner (all JS preferable) way of doing this.
Something like this, but I believe this is an out-dated solution code...

I have a list of most 17 recent entries from a db table and wanna use jquery/ajax to have a next button that loads the next 17 entries when you click it. It passes the 17 variable to the .load which works fine first time around (this is later used as mysql limit), but then I try to increase the start variable with 17 so that next time I click it would pass 34 to the .load (so it loads next 17 again) but this doesn't work, it simply loads same 17 again on 2nd, 3rd ect. click (so nothing changes). use global variables by setting it with var and using it without var inside the function.
<script>
var start = 17;
var loadUrl = '<?php echo site_url('welcome/battles'); ?>';
$("#latestbattlesnext").click(function () {
[code].....

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?

I'm having some problem with return value for a function. I'm trying to access google blogger's API to display blog entries on my site. I'm doing this through JQuery and requesting a JSON response. Everything seems to work ok, but I want to access the link for the blog entry. This is a subset of the "entry" object.
It's structured like this:
Entry:
title,
content,
link:
rel,
type,
href,
rel,
type,
href,
I want to get the link where the "link.rel == "self". To do this I have to loop through the link object (5 times). The loop and conditional statement works correctly, but I can't get the variable inside this loop back to my original function.
I have this code:
$.each(data.feed.entry, function(i, entry){
$.each(entry.link, function(j, link){
if(link.rel == "self"){
var postlink = link.href;
alert("link : " + postlink);
return postlink;
}});
alert(postlink);
});

so i wrote this slider with some help from an admin, everything works as I would like it to but I'm trying to make it a plugin so i need to tighten up a certain part of the code:
(function( $ ){
$.fn.jmSlider = function() {
// get total width of all li elements in the slider
var wrapWidth = 0;
[code]....
what i would like to do is instead of using "li:first" and "li:last", i would like to use first-child and last-child so the element doesn't need to be a li, in can be anything that is the direct child of the parent container.

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?

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.

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?
