What advantage does adding elements via document.createElement have over writing markup naturally with innerHTML?
[Code]...
The latter method has much more overhead and is considerably more difficult to write with. However, there must be an advantage of some sort to doing it this way, but it's not exactly clear to me why.
This is driving me insane. I'm trying to use createElement inside a loop to make some <divs>, each of which has an onclick event. I threw together this test page to demonstrate it:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
[Code]....
When I click on any of the boxes it alerts "5", the final value of x after the loop ends, instead of what the value of x was when the loop executed and created the element ("0", "1", "2", etc.). This is happening if FF and ie.
I also noticed in Firebug if I put a breakpoint on the "yay.onclick=function(){alert(x)}" line that it will break everytime I click on one of the boxes. Very strange...
How can I put in a variable on the yay.onclick=function(){alert(x)} line and have it "stick"?
In IE6 and below, when using createElement and appendChild to add a new select element to the page, it automatically selects the first option.
the page relies on using the onchange event of the select element, and if there is only one option and it is selected, there is no possible way to fire the onchange event.
To get around this, i've had to use innerHTML to build the select element, which I feel is dirty so I want to clean it up.
Any idea's? I have already tried setting each option's selected value to false, etc but nothing other than using innerHTML seems to of worked,.
I'm using the document.createElement method to add dynamic table and from elements to a page, but I'm running into a problem where I'm adding 2 objects to 1 cell. The two of them combined are not wider than the cell, but they won't display next to each other, they're always on their own lines and I can't figure out why...
HTML Code:
var hiddenElement = document.createElement('input');
hiddenElement.setAttribute('type', 'text');
hiddenElement.style.cssText = 'width: 100%; display: none;';
[Code]....
The text input (hiddenElement) should fill 1 line of the cell, but then the two buttons (createButton and cancelButton) should both sit on the line below it, but the cancelButton insists on siting on it's own line below the creatButton, and I can't figure out why.
(I know they have their display set to none, that's being set to block by a function, which is how I know they're all on their own line)
I am having trouble with adding a dynamic form to a DIV through innerHTML.It is a Paypal BuyNow button where the values change according to the thumbnail previously selected.I imagine the syntax is wrong... Is this something even possible?

I am adding drop down boxes to a div using javascript on a user action, if these boxes are assigned a value by the user then the user adds more boxes the values previously selected are cleared.
It does not happen if an option is selected in the HTML when the page is loaded.
I want to insert html/php content into my existing html. I've put together the following code, which works except for the first line:
div.innerHTML = '<param name="userId" value="<' + '?php echo $_SESSION["userId"] ?' + '>">
<param name="id" value="' + id + '">
<param name="title" value="' + title + '">
<param name="type" value="rfq">';
The first line incorrectly comes out as:
<param name="userId" value="<?php echo $_SESSION[" userId="" ]="" ?="">" />
I want it to come out as (after being parsed by php):
<param name="userId" value="user123">
I'm a student and am trying to write some very simple code. My problem is I use innerHTML in my script file to send some text to a div in my html. When it's sent it renders and then quickly disappears. I've attached my code.There are two separate "files" .html & .js:

I have two problems that I suspect will be bread-and-butter problems for the
more experienced guys on here, but I'm not the greatest with js.
NB: Code snippets at the bottom
The first problem is that after a bit of fiddling I'm getting am 'Object
Expected' error when I click on the Depot dropdown which I can't seem to get
round. The code I had was working OK but then I cut it all out, tidied it
all up, and put it back in and now it doesnt work.
The second problem is a 'How do I...'. I'm using an XML data island to
retrieve some data without submitting the form. In the first example, when
the user selects a Customer, the Depot list is updated with all the depots
for that customer; This all works fine. What I want to do now is retrieve
some more data when the Depot is selected.
I have the XML bits working; the js code snippet correctly output a series
of msgboxes with the correct value in (or at least it did until I introduced
the Object Expect error!).
However, I'm unsure as to how to display this information on the page. The
XML contains a series of Part No's and Quantities, which I'd like to display
in a table towards the bottom of the screen. The problem is that I don't
know how to dynamically create and populate this table.
The only caveat is that I dont want to show the table if no values are
returned from the query....
I'm trying to find a way to add an attribute inside an anchor. I want to do this is because that attribute is required by a script I have running on the page, but it is not valid.Just so it makes more sense the code looks pretty much like this:<a id="previous" control="-6" href="#"></a> and I would like to add control="-6" inside <a> via jQuery, only I don't know how.

$(document).ready(function(){
$('#holder').html('<a href="#" id="foo">Hey!</div>');
$('#foo').click(function(){
[code]....
I sometime find it useful to add my own attribute to a HTML tag so that my javascript can access those elements.
For instance, new_attribute in the following anchor tag:
<a href="#" class="someclass" new_attribute="some_value">Click Me</a>
When trying to validate this page, however, it doesn't pass. Some of the below questions likely do not make sense, but I hope you get the idea what I am looking for:Is what I am doing bad practice?Is there another way to allow javascript to specifically select just some elements and not others? Should I instead apply multiple classes to the element, and use some of the classes not to modify appearance, but to allow just them to be selected?If using custom attributes, should they somehow be defined so they pass validation?
I have a table as follows:
<table>
<tr>
<td>col 1</td><td>col2</td>
</tr>
[code]....
You see it doesn't want to output the I have specified. The actual script is a lot more complex and so unfortunately manually adding each using an appendChild or similar function would be far too time consuming and probably rather resource intensive. Is there anyway I can just add a 'chunk of html' to this table row and in this chunk define the table columns?
I'm trying to add a certain number of row in one click via javascript. So far I could manage to add one row but is there a way to add multiple row in one click? Also can I add colspan to it?

I'm trying to create a function which shows a hidden response when a button is clicked on.I also want to add the response to a variable which lists all the users responses.Here is my code now...
$(".yes").click(function () {var feedback = feedback + $(this).html();
$(this).parent().next("p").show("fast"); });
$(".no").click(function () { $(this).parent().next("p").next("p").show("fast"); });
$("#email").click(function () { alert(feedback) });
The bolded line is the part which isn't working.
I am using a dialog box plugin. I need to add a button so I use html statement like below:
'<input id="myButton" type="button" value="test" />'
This renders just fine but I don't know how add an event for the button or even add this button to the DOM.
I use .prepend to add html contents in an existing html tag. When i view the source in IE i can't see the added content. I tried it with Chrome and it's working and see the contents immediately.

I have a table that displays a list of groups. You can add, modify, or remove the group. I have three functions in my JS:
[Code]...
Using AJAX, PHP, and jQuery, when I add a group, it posts to an "addgroup.php" file, and then returns that data in JSON format, and I then tell jQuery to display that data in HTML. Here's the problem now... The table does not render properly. There is no padding/margins. Even worse, if I Add a group, and then click the "X" to delete the group (without refreshing the page), the data posts, and returns (i get a response in my console confirming the removal), but the entry that I just added does not disappear (as it should) unless I refresh the page. When I add a group, and then view my page source and inspect the element, all of the appropriate HTML is there, but it just doesn't seem to be rendering right.
I'm not new to JS, or the web and it's various other technologies, but I ran into a problem. I'm trying to add an event handler for a click on all HTML span tags. Trouble is, getElementByTags() doesn't work and neither does getElementByTagNames(). Strangely, adding an id to the span tags and getting their id's do trigger the handler.
Code:
document.getElementsByTagName('span').addEventListener('click',doSomething,false);
function doSomething() {
alert(this);
I am writing a web application and had a question regarding the best was to append values to an HTTP Post.
For my get requests, I am using jQuery to append auxiliary data using .load as indicated here:
As you can see I am sending along extra value's with my get requests that controller Servlet uses to send back the right data.
In addition to the get requests, I would like to add some extra data to my forms so that I can have Servlet controller perform the appropriate tasks.
Is the best way to do this by adding a hidden field to HTML?

I have a pretty basic HTML form, it doesn't go to a database or anything, it just gets emailed directly to the owner of the website with their customer query.However, the owner has now asked that each query be assigned a random reference number of no more than 16 digits which must also be visible to the customer.I presume this will be relatively easy but I'm a complete beginner with Javascript which I assumed would be necessary for generating the number. I've sort of figured out how to generate the number but I can't figure out how to get that number into a read-only field on the form so that it will be both visible to the client and sent with the rest of the data on the form to the owner.I've had a number of attempts but this is what I'm trying at the moment:

Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
I am putting the finishing touches to a custom written (pHp) article editor to allow users to publish content on a website.I have basically finished the project, and I am putting the finishing touches in with jquery widgets, such as a word counter. I would also like people to be able to highlight a section of text, then have some custom tags wrap the text (much like on this forum when you highlight a word in the message box and hit the wrap button).I would like my own custom tags to be used, such as <span class='someclass'>some entered text</span> rather than predefined ones.
