JQuery :: Clone() Is Too Slow If The Elements Are Inside A <form>?
Aug 28, 2011
Hereyou can find the whole example. By clicking onClick to Addyou will clone 100 times the elementtrackOn; then it will be append to the tabletracklistOn. Unfortunatly, if these elements are inside aformyou can see that the time is very high before the process is finish.If I remove the form, is quite immediate. Why this behaviour? How can I fix this problem? P.S. I don't know why, but I can't paste the whole code here. So follow the jsFiddle link please :)

I have a FORM with many elements, and some of them have names like "name1[]", "name2[]", etc..
I would like to create a button that, once clicked, will clone all the elements whose names end in "[]" (including labels, and select's options), giving them the same name (and possibly a different ID, but it's not important).
I am completely new to jQuery and almost new to javascript.
I came up with this code to clone the entire form:
<script type="text/javascript">
$(function(){
$('input.cloneMe').live('click',function(){
var f=$(this).closest('form').clone(true);
[Code]....
But how can i tell him to only clone the elements whose name ends in '[]' ?
i need to us instead of closest, but i really don't know what.

I have a block of HTML that I am cloning, as I want to manipulate it to remove an element, so that I can then append that new HTML somewhere else on the page.
[Code]....
Then in the jQuery, I have tried many different ways of removing stuff from that clone, but with no luck. E.g.
var cont = $('#container').clone();
$(cont).remove("copy_btn").appendTo("body");
There are no errors showing up in Firebug, but the html added to the bodu still contains the link with the id "copy_btn". Is this even possible? The api says that remove() will remove matched selectors from the DOM, so as this is just a set of elements is that the reason? If so, is there a way to achieve this, or would I have to append it somewhere on my page and then perform the manipulation?

I'm having trouble using jQuery to find get select box values by element name. At the moment the code is in a for loop and it gets 8 different form values and puts it into an array. Currently this takes 1.5 seconds to execute which is far too slow as the user has to wait for it to finish. Here's the code which is inside the loop:
[Code]...
This when run executes instantly with no time delay. Why is the jQuery way so much slower? I'm all for saving 2 lines of code but not when it's 10x slower. Also I shouldn't need to put an id on the select box element to make finding it faster, the name value is already unique because I require the specific value once the form has been submitted.

'When my form is submitted, I have onsubmit pointed to the following
code snippet. But, the button is not actually set to disabled and the
style.visibility changes are not made for several seconds. It appears
that it goes into validateForm and doing the rest of this snippet
before the browser makes the changes.
How can I get the browser to immediately make the UI change?
function submitForm(servleturl) {
var submitbuttonelem = document.getElementById("submit");
submitbuttonelem.disabled = true;
document.getElementById("modgradeform").style.visibility="hidden";
var mydiv = document.getElementById("contentarea");
mydiv.innerHTML = "Validating the form.";
mydiv.style.visibility="visible";
var ret = validateForm();

Recently submitting forms (specifically forms which have javascript attached
to them with the submit function) has become very slow. The browser appears
to sit there for seveal seconds doing nothing (the page also becomes non
responsive) and then suddely loads quickly. This happens on all of my
computers... What's happened to javascript? Is there some setting that's
been turned on that I'm missing?

I am trying to use the remove() jquery function.
I appended elements inside this div. But I want it where if a check box is checked then that element which is an a tag html element that will be removed.
The problem... when lets say append 3 <a> tag elements. when I remove all 3. Then append like 4.. I see like gaps. like I want it where if I delete the element it will float upwards. what that means that if I got 3 elements and I delete all 3 and then append 1 new one... then that new one should be shown at the top of the div. Not displayed a little bit lower then where the 3rd element we removed was located at.
It seems like that html code that is appended still stays there for some reason.

I am having troubles manipulating DOM elements inside a variable. I have the following code:
var
$content =
pages[pageId].page;
$('.widget_inline'
[Code]....
Inside this html string there are multiple id's that I have to change. The .each finds the rightelements and the manipulation seems to work when I do a console.log onwidgetElement.However the actual $content remains unchanged. I probably made a very obvious mistake but I can't find it.

Let's say I have this paragraph..<p>My dog is brown.</p I would like to accomplish this.. <p>My <span class="animal">dog</span> is brown.</p> So, I want to use JavaScript to find all "dog" strings inside the paragraph and wrap them in a SPAN element of a given class. I would love to have a plug-in that does that... like this: $("p").findAndWrap("dog", "<span class='animal' />"); I know this can be done in JS, but I'm not particularlyexperiencedin JS string manipulation, so it would take a while until I would accomplish this...Is there a plug-in that does this?

i am working on a custom drop down list that has hidden #options DIV which is shown when the user clicks on a button. the problem i am having is that the click event does not seem to be attached to the LI elements since they are hidden when the page first loads. if i show the #options DIV when the page loads everything is working as expected.i've tried to attach the click event after i show the hidden UL but that didn't work either.what can i do to make sure the LI click event fires? i tried to put A tag inside of LI and attach click to that but to no avail.
<style type="text/css">
.gbtn-options {

I'm using the $ function to get an element using ID:
function $(e){return document.getElementById(e)}
I'm trying to extend this function to use it like this:
$("myID").s("div");
In order to get all the elements that are DIV inside element ID "myID". So I wrote this:
$.s=function(es) {return document.getElementsByTagName(es);}
But that's not working.
What did I do wrong?
Also, Is it possible to to somehow extend it to use with endless number of inside tag/id? like: $("a").$("b").s("div").$("c") ?

I was wondering how to split the elements inside each other, so that each of them has its own background color. What I'm trying to do is to highlight background of each element onmouseover. Up till now I haven't managed to do it properly - for example, I have a table cell with a hyperlink inside it. When I point to the cell - background changes, however, pointing to the hyperlink leaves the cell coloured - which is what I don't want. I'm trying to use this code:
HTML Code:
onMouseOver="this.style.backgroundColor='yellow';" onMouseOut="this.style.backgroundColor='white';"

I have a fieldset with a bunch of input's inside.
I am wanting to put all of these elements inside the fieldset into an array.
Then once I have that array use a for loop to iterate through each of the elements values and display them with alert.
This is what I have tried, but am expecting to be a fair bit off the mark.

I'm working on an exercise I need to have finished pretty soon. The concept is simple: online bookstore with cart etc. It's written on php, using JS and mysql.
Each time I view a book's details, I can add it to my cart, where I can also alter it's quantity.
The code for my cart is this:
PHP Code:
As you can see, each time I choose a book to add it to my cart, a new span will be created, to hold the info of this book. What I need to do with the ManageItem js function, is to update the total cost at the bottom of the page, but I can't seem to be getting anywhere.
Here is what I've done so far:

I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?
