JQuery :: Dynamic List - Remove Function Works Wrong
Aug 30, 2011
I'm working on dynamic list with jQuery. I've appended hundreds of <li> elements with for loop to make very long list. When user scroll down again, remove older ones and append new ones at last of the list. I used$('li:lt(50)').remove() to remove first 5 elements from the list. At first, it works. But, for the second time, it always delete half of '50'. When I enter 100, only 50 elements deleted. How can it be? Could you check the ':lt(n)' selector and remove function? My HTML is very simple. only <UL> <LI> tags in the body. Tested on latest Chrome(ver.13.0.782), jQuery 1.6.2.

This is an example of what I currently have. There is also a button which adds more rows. It wasn't too hard to get it working using CSS and innerHTML:
<div id="main container">
<div id="row-1">
<input.....
</div>
<div id="row-2">
<input.....
</div>
etc
However, due to mass css headaches with the layout, I' like to see if it can be done it tables instead and using the DOM methods (nodes, createElement etc)
so far, the examples I've seen either don't allow the same functionality or don't work across IE5+(win), and modern versions of FFox, Safari and Netscape (MAC + WIN)
Does anyone know of a good class/example/tutorial?

I am having difficulties to deal with a simple remove function.
I have an item list with "listitem" css class. I placed a button on each item to delete it. I am now trying to use the remove function to erase it from the page. I thought $(this).remove(); will work but it doesn't. I also tried something like this: $(this).parent('.listitem').remove(); but it didn't work.
When I write $('.listitem').remove(); it erased all the items of the list. I m just trying to be able to erase just the one clicked.

I've been beating my head against a wall for a few days trying to get this working. I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:

I'm having trouble passing data in an array to a javascript function. I dynamically create a list with edit links on each row and pass the array to the function on each link. Of course, the function only gets the data from the last row, regardless of which link is pressed. Here's the code:

I have links in my tab panels. Those links are broken because (from what I can figure) the remote tab section in the ui.tabs.js file adds #ui-tabs-(some number) to those links.
var id = self.tabId(a);
a.href = '#' + id;
What can I put in my tab function:
jQuery(document).ready(
function() {
jQuery("#tabs").tabs();

I am creating dynamic questions and question's choices (radiobuttons or checkboxes) from database when runtime..after users answer the question, press next button to pass the next questions
For example
1) Question definition
a)choice definition
b)choice definition
c)....
Users have to choose any choices..if not, my system is giving alert, Actually my problem is about checkboxes. I created hidden textboxes, if question choices' type is checkbox. So the last choice definition is name "Other". If user checks the other choice, the hidden textbox is going to be visible. It is all okay until here. I want to give a error alert if user checks the other choice and doesn't fill the textbox when press next question. I don't validate this. How can i do it.

I have a table that has parts with multiple characteristics. Part Number, Height, Width, Capacity, Price, Etc. I would like to have a drop downs for all of these values, when a user selects one of these values it will filter the results into a list. Ex. user selects a part that has a Height of 6 and width of 10 it will only list those parts. As I said earlier, I have a script that will give me all the parts, however I am not able to make the onchange list parts with multiple values.

I'm trying to allow users to add the text from a text input into a list, and then have the option of removing this list item. So far I have the code below which allows me to add a styled list item with a link in it which I would like to close the box when clicked but at the moment when I click it nothing is happening. I'm not sure if I'm approaching it correctly or if there is an error in my code.
jQuery(function(){
$('#addTask').click(function() {
var Task = $("#jobTasks").val();
if (Task == '') {

The following code works fine in FF and Chrome for getting a radio selections value but not IE8.
$('input[name="search[gender]"]').change(function()
{
var check = $('input[name="search[gender]"]:checked').val();
Inputs are below:
<input type="radio" name="search[gender]" value="1" class="v_middle" />Male
<input type="radio" name="search[gender]" value="2" class="v_middle" />Female
<input type="radio" name="search[gender]" value="3" class="v_middle" />Couple
<input type="radio" name="search[gender]" value="4" class="v_middle" />tv
<input type="radio" name="search[gender]" value="" checked="checked" class="v_middle" />All
The first time you click a radio button in IE8, no value is returned at all (tested with document.write of the 'check' value), with an error "'null' is null or not an object". The second (and rest of the times) you click any of the checkboxes the wrong value is returned, it returns the value of the currently checked button (which we checked a moment ago) rather than the one we have checked the second time. Does Internet Explorer have issues with this onchange function method? Or is something wrong with my code?

I would like to achieve the following... I have the following list:
<ul class="menu">
<li><a href="something.html">First main</a></li>
<li><a href="something.html">Second main</a>
<ul class="sub-menu">
[Code].....
Now, I'd like to remove the link from the "Second main" because it has a submenu. I know that I can get that exact item using $("ul.sub-menu").parent() but how do I unwrap the link in it?

I am relatively new to js, but I did think I was starting to get the
hang of it. Then this happened...
I have a form with an onsubmit event handler:
<form id="uploadForm" method="post" action="..."
onSubmit="checkDates()">
The event handler does some minor validation, then returns true or
false:
function checkDates(y, m, d) {
if (endDate.getTime() >= startDate.getTime())
return true;
alert("Start date must precede end date");
return false;
}
(The arguments to the function are used when it is called elsewhere,
not as onsubmit.)
I also have a library class which needs to process the form submit, so
it hooks onsubmit like this:
MyClass.setOnSubmit = function(listId) {
var list = document.getElementById(listId);
var form = list.form;
var f = form.onsubmit;
if (typeof f == "function") {
form.oldOnSubmit = f;
form.onsubmit = function(){
var ok = this.oldOnSubmit();
if (ok)
return MyClass.onsubmit(listId);
else
return false;
};
}
else
form.onsubmit = function(){MyClass.onsubmit(listId);};
}
My problem is that the value returned from oldOnSubmit and stored in ok
appears as 'void'. This happens in IE 6 and in FireFox 1.07. Can anyone
explain what's happening?

I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?
function wait(time) {
while(1){
setTimeout("break;",time);
}
}
function wait(time) {
var flag=0;
while(flag=0){
setTimeout("flag=1;",time);
}
}

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in Google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
When you run the code, the first alert will show all the values that a were passed to the function. The second and third will show what was written to the document.
If you try clicking the next button after the code loads, the values that result will be unusual.
<script>

I am doing a Validation for Form "Text input". If the user leaves the input empty, a function is starting to run. If the field is bigger than 1 - so it doesn't get into the function.
The problem is: The first time, the user left the input empty, function ran, and I got the alert - that's OK. Second time, The user added 10 in the AGE input - And again he gets the Alert - But he should not.
Note: Age input value, returns from a different function (calc) to a var called: result.

I am using the vertical scrollable by Flowplayer. There is one aspect of the set-up I can't get to work.
I have Scrollable working on a dynamically generated category list in Wordpress. There could be as many as 15 items in the list, but I only want to display five at a time. In order for Scrollable to work properly, each batch of five list items needs to be wrapped in a div (see example below). I'm pretty sure this is something I should be able to do in jQuery, but can't figure out how to do it.
Ideally, it should also work if there are only 12 items in the list by ignoring the missing three to make a multiple of five.

I'm loading another html file full of list items. What I would like to do is hide() the content right after it's loaded, and then fadeIn(0 each individual list item one at a time.
The problem is, it's loading all the list items at once. I don't know what to do. I could code the chain manually, but only if I knew the number of items in the list would never change. I'd really rather set it up to fadeIn any number of items dynamically.
Here's my code, which I know doesn't work, but maybe you could see what I am trying to do:
function loadContent(location) {
$('#content').load("assets/content/"+ location).hide();
var x = $('li#content').size();
var y = x - 1;
