JQuery :: Looping Through Arrays - Attribute Value
Sep 13, 2010
I have a list of inputs
<div id="divID">
<input title="foo" type="text">
<input title="bar" type="text">
</div>
Then I'm trying to use jQuery to cycle through each input and ascribe ".attr("value") to each respective <input>. So far I've been using something along these lines:
var input = $('#divID input')
input.each(function(i) {
var title = input[i].attr("title");
input[i].attr("value", title);
}
If I remove the "[i]", it fills in every box with the title of the first <input>. If I leave it there, it fills in the first input, and then upon looping, says input[i].attr is not a function. So, if I type console.log(input[1]), firebug returns the correct <input> tag, but as soon as I add the .attr(); function, it blows up.

1. I have this list of 3 products/items that is created and displayed automatically through a for-loop. By changing the number in this loop, I can either add or subtract items of this list. More and more items are supposed to be added to list on a regular basis.
2. For each item, a number of customer-comments should be displayed and looped. I accomplish this using Arrays, where I can easily add new comments for each individual item to the loop.
3. Each item may have a different number of comments.
My goal is to have a system that effeciently allows me to add new comments at a minimum effort from my part.The comments loops fine, as long as I only choose to loop them for one item at the time. As soon as I try loop comments for two or more items at once, trouble ensue.
Below is my code:
Code:
<SCRIPT LANGUAGE="JavaScript"><!--
//SBC verdicts
verds_sbc = new Array(new Array("Great Game!","Good game!","I love this!"),new Array("AVGN","CurlysWorldof SOftware","ANGRY JOE"),new Array("www.cinemassacre.com","www.curlyswordsofsoftware.com","www.angryjoe.com"));

I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way?

i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
$("<div/>",{
id: 'tooltip-'+rand,
class: 'dock-tooltip',
[code]....
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....

I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.

I'm learning jQuery with XML. I'm familiar with other query languages such as XPath. I'm having a little bit of difficulty wrapping my brain around how jQuery works but I think I can make the leap if I see a solution to a problem I know how to solve with other methods Given the following XML, please share a jQuery solution to finding the value of attribute B in elements named bar where attribute A has the value 30:

I'll trying to tell the difference between the following three cases:
<img alt="text string" />
<img alt="" />
<img />
I can do this in Firefox with the following code, where elem is the
HTMLElement representing each image, but IE doesn't seem to
differentiate between empty string and undefined.
var alt = elem.getAttribute('alt');
alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really
difficult time trying to figure out what's going on...

I have 5 buttons all using the same code:
$(".but1").mouseenter(function(){
$(".but1>.launch").animate({ left: "10px"}, 250 );
});
$(".but1").mouseleave(function(){
$(".but1>.launch").animate({ left: "0px"}, 250 );
});
$(".but2").mouseenter(function(){
$(".but2>.launch").animate({ left: "10px"}, 250 );
});
$(".but2").mouseleave(function(){
$(".but2>.launch").animate({ left: "0px"}, 250 );
});
$(".but3").mouseenter(function(){
$(".but3>.launch").animate({ left: "10px"}, 250 );
});
$(".but3").mouseleave(function(){
$(".but3>.launch").animate({ left: "0px"}, 250 );
});
$(".but4").mouseenter(function(){
$(".but4>.launch").animate({ left: "10px"}, 250 );
});
$(".but4").mouseleave(function(){
$(".but4>.launch").animate({ left: "0px"}, 250 );
});
$(".but5").mouseenter(function(){
$(".but5>.launch").animate({ left: "10px"}, 250 );
});
$(".but5").mouseleave(function(){
$(".but5>.launch").animate({ left: "0px"}, 250 );
});
Is there a way to do this in fewer lines of code?

I have a function which is executed whenever someone clicks a checkbox on the page. There are lots of checkboxes on the page. I want the function to be performed on only the unchecked boxes. I've tried this two ways, neither of which has worked. Here are the two methods I've tried.
Method #1
$(".item input:unchecked").each(
function() {
if ($(this).val() > diff) {
[Code]....
Where diff is an integer and the values of the checkboxes are all integers. The problem is the function ends up getting run on all checkboxes, even boxes that have been checked.

I have a problem with a function i created. I want an image to move from a to b and then start from a again. Without parameters this works really fine, but now that I have got more images I use parameters but I have no clue how to call the funtion again.
[Code]...
I tried to replace show(100,flo) with show(100,flo(zahl,r_g)) but then the divs only move from a to b but even will not come back to a again. I think the solution should be pretty simple but i cant figure it out.

I'm having an issue with looping a set of divs that are positioned on top of each other. When a link is clicked, the second div should fade in as the top div fades out, which coincides with another div changing background colour.As you'll notice, when the link is clicked for a third time, it loops back to the beginning by using the rel tag to keep track of what div is showing. The problem is that when it loops to the beginning the animation is not in sync with the second div changing colour.The code for all three is exactly the same and it doesn't matter how many coloured divs you have, it's always the last one fading out that causes the issue. The '#second' colour change fires after the box changes, not synchronised like the previous clicks.This is a basic example that I'm using on a site elsewhere so the concept of the second div fading in and then the first fading out is important - I can't switch so the first fades out then the second fades in.

I was wondering if there way a way to loop through elements that contain a data key applied by data(). I couldn't find a selector for data keys.
This for instance, I would like to give me the value of 'foo' for where ever it has been applied.
$(document).ready(function() {
$('body').data('foo', 52);
$('head').data('foo', 32);
});

I want to loop thru all the hidden fields on the page, that have an ID which starts with "general_" and ends in "_10". Eg IDs:
id = "general_name_10"

How can I do such a loop in jQuery?

I would like to loop through elements that are NOT disabled. So far my code is:
$("#addlivestock :input").each(function(){
if($(this).find().attr('disabled','disabled'))
{
var getAttr = $(this).attr("name");
[Code]....
When I click a button that code fires. When that code fires all the elements that aren't disabled get disabled. My code does NOT work as expected and I found the problem, which is if($(this).find().attr('disabled','disabled')). how to loop through form elements that are NOT disabled.

I have a quandary of sorts here dealing with a list of checkboxes and the hiding/showing of a few divs associated with the checkbox selection. Here's basically what I need to do: Hide the lower div if no checkbox is selected. If any one of the first 6 checkboxes are selected, and NOT any of the remaining 6, then show the div. If at any time during selection one of the remaining 6 checkboxes are selected, then hide the associated div. Note this code doesn't really do much. I'm still trying to architect a solution that's best.
var aThroughf = false;
var gThroughl = false;
$('[name="'+q2030.name+'"]')).live('click', function() {

take a look at following link and let me know how I can add a loop to my script in order to repeat the animate() function for example for every 30 seconds?
[URL]
as you can see the animate function just runs for one time but I would like to repeat it for every 30 seconds. I also would like to add a function to stop the animation when user mouse over on the Logo div.
Here is the code
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Moving Div</title>

The SELECTor shows up in the document but it's not MULTIPLE, no ALT text, no CLICK event handler.

I don' t know what I'm missing here..
$("div#carousel a").each(function(i) {
$(this).click(function(e) {
e.preventDefault();
console.log(myArray[i]);
});
});
it doesn't loop, it always prints the first item in the array (there are 18 <a>'s inside div#carousel, and 18 items in the array...)
