Document.createElement() In XHTML
Nov 25, 2006
I try the following in Firefox and other modern browsers:
window.addEventListener('load', function() {
document.title = CSS.getClass('fontSize');
var div = document.createElement('div');
document.getElementsByTagName('body')[0].appendChild(div);
alert(div);
alert(div.style)
}, true);
It works fine in normal HTML mode (Content-type: text/html), but in
XHTML mode it alerts "[object Element]" instead of "[object
HTMLDivElement]" and the second alert shows "undefined" instead of
"[object CSSStyleDeclaration]". So I can't reach the style declaration
which is important for me. Strict mode makes trouble again and again,
the biggest bug: document.write does not work:

I've been creating a script that dynamic loads js files.
but after creating that script, (and i use
document.createElement('script');) in that function.. i've realise that
the code that shows up in the browser is:
<script type="text/javascript">
should it be
<script type="text/javascript" />
or
<script type="text/javascript"></script>

I have a page which uses JavaScript to create form elements using
document.createElement('input'), etc.. Both Firefox and IE have no
problem accomplishing this and when the form is submitted all the
information is passed correctly.
I am now trying to validate the form using JavaScript when the page is
submitted. Firefox has no problems with this but IE returns
'document.form1.*THE FORM FIELD*.value is null or not an object' for
the elements that were created using document.createElement when I try
get their value using 'document.form1.*THE FORM FIELD*.value'. How do
I get the value of the form elements that were created using
JavaSCript?

I'm experimenting with creating SVG dynamically and am finding that document.createElement is changing the case of the tags I input. This is breaking because, apparently SVG tags are case sensitive. For example, when I try to create a linear gradient element like so:var grad = document.createElement('linearGradient');what appears in the view source is:<lineargradient ...> (Note the lowercase "g")The tag doesn't work if the "G" is lowercase. Is there any way to specify in the <html> tag (or somewhere else) that the document should preserve tag case?

So i'm trying to create an onchange within a createElement of a textfield and it doesnt work, this is what i'm trying:
Code:
inputEl.onchange=function(){this.value=$('ship_pueblo').innerHTML = $('stateSelect').value || '';};
My entire working code without the onchange i'm trying to pull of is:
Code:
// Create the Input Field
var inputEl = document.createElement("<INPUT TYPE='text' NAME='state'>")
inputEl.setAttribute("id", "stateSelect");
inputEl.setAttribute("type", "text");
[Code]...

Why doesn't the following code work:
<script type='text/javascript'>
var canvas = document.createElement('canvas');
canvas.width = 1400;
canvas.height = 700;
var context = canvas.getContext('2d');
context.strokeRect(10, 10, 50, 50);
context.stroke();
</script>

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)

How can I make an XHTML-compliant form of an expression in this
format:
document.write("<scr"+"ipt type='text/javascript' src='path/to/file.js'>"+"</scr"+"ipt>");
this turns out to be a non-trivial exercise. inserting '<' and
'>' causes the browser to write the text to the page as literal
text rather than as the intended script element. Using escape codes
seemed to work (makes it standard compliant) but the text is not
written to the page.
The point is to have a conditional branch in which, when a certain
condition is true, a script tag will be generated that will call a
JS include that responds to the specific condition.
This procedure works in the present implementation -- but fails XHTML
compliance testing. Now, we would like to have both.

I am attempting to create an element (to be added later to the document DOM) using createElement.My test case is just:document.createElement("<p>Hello World</p>");My error console shows the following error:

I've written the following small feature test.
[Code].....
I want to remove 'div' before returning the function. Testing in IE something like div.parentNode.removeChild(div); will fail. If I look in the dom 'div's parentNode is null, so that explains that. It needs to be appended to something first I guess.

MSIE 6.0 apparently does not support protyping with objects created
with document.createElement, while Firefox does.
I tested it by typing it into the adress bar, but it also appears to be
the case for code embedded in a HTML document. Here's a simple segment
of code to demonstrate the difference:
javascript: function myObj(){};myObj.prototype =
document.createElement('a'); var x = document.createElement('a'); var
y=new myObj(); var z= new Object(); alert(x.href) /*blank in both FF &
MSIE6 */; alert(y.href) /* blank in FF but 'undefined' in MSIE6 */;
alert(z.href) /* 'undefined' in both FF & MSIE6 */;
I wonder why that is (apart from the fact that MSIE implements JScript
and not javascript), and can anyone tell me which of both browsers is
complient with W3C standards?

The document object has a method called createElement. Can I use this
method to create a new Drop/down list, like:
var sel = document.createElement('SELECT');
I have seen it used like this:
opt = document.createElement('OPTION');
which means that opt now holds an option that can be appended to an already
existing select object.
Are there any restrictions for which arguments createElement can be called
with? I have seen: var what is "LI"? Where do I need to look to find valid arguments for createElement??

I have a snippet of code below that creates a new input element for a
checkbox and sets some attributes.
var observationCheckbox = document.createElement('input');
observationCheckbox.setAttribute('type', 'checkbox');
observationCheckbox.setAttribute('id', 'observation.' + runningCount +
'.species');
observationCheckbox.setAttribute('name', 'observation.' + runningCount +
'.species');
observationCheckbox.setAttribute('value', 's' + speciesCode);
Question: Is it possible to set this checkbox to be 'checked' when it is
created? I'm not sure if this constitutes an attribute or not.

<table id="test" style="width:200px;border: thin solid blue;">
<tr>
<td>
Test row 1
</td>
</tr>
</table>
I have a table like above and want to use document.createElement to insert a new row at the end of the table before the close table tag, is this possible?
My efforts so far have resulted in the following html:
<table id="test" style="width:200px;border: thin solid blue;">
<tr>
<td>
Test row 1
</td>
</tr>
</TBODY>
<TR>
<TD>Test row 2</TD>
</TR>
Which doesn't display properly as table has already been closed
This is the code I've knocked up for the test so far:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Untitled</title>
</head>
<script>
function test(tableObj)
{
alert(tableObj.innerHTML);
//var newTable = document.createElement("table");
var newRow = document.createElement("tr");
var newCol = document.createElement("td");
newCol.innerText = "Test row 2";
newRow.insertBefore(newCol);
tableObj.appendChild(newRow)
alert(tableObj.innerHTML);
}
</script>
<body onload="test(document.all.test)">
<table id="test" style="width:200px;border: thin solid blue;">
<tr>
<td>
Test row 1
</td>
</tr>
</table>
</body>
</html>

this works perfectly in firefox - but in internet explorer it just creates the first lable and the input field, although it creates the input field as a regular text field instead of for files. the caption label and text field aren't created at all. any ideas? Code:

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"?

I'm having trouble parsing through a table in I.E. Of course it works fine in firefox and chrome. I'm pulling html off of a txt doc and storing it in a temporary div made with createElement so I can go through and parse out the data. Code is below:
[
Code:
var tempdiv = document.createElement("div"); //create temporary element to store html content in
tempdiv.innerHTML = html; //dump html content into new element
[Code]....
It returns 0 for rows and and cols. If I use a getElementsById and grab a table already on the page it works fine.

I am trying to include and xml document inside my xhtml document. There
are a number of reasons for this including portability, multiple
interface generation, and scalability of information.
My problem is that javascript is understanding the nodes in my xml
document as html elements.
<xml>
<book>
<title>Lord of the Rings</title>
</book>
</xml>
If I parse this, the title element cannot be extracted and the page
title(in the browser) becomes "Lord of the Rings".
Is there a way to exclude this xml node from the xhtml rules?

Maybe you can answer a question for me: I'm reading the preview for XML web development (sitepoint book) and it clearly shows IE rendering XML (the author states IE5 and above); does that mean that IE's problem with XHTML is CDATA and not XML universally? If that's true then IE could render an albeit gimped XHTML page which would explain why HTML 4.01 and XHTML are virtually synonymous in IE 6.
Is there a workaround for this in JavaScript, if the above is true?

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 trying to integrate PayPal's MiniCart on my site, and I don't have much javascript experience. I did however find that this little blip of code is what's used to position where the cart is placed on the HTML page that contains the script. Here's my problem - I want to be able to create this element inside a div that already exists on the HTML page. Is this possible?
Code:
var container_pp = createElement('div', cart, {
id: 'PPMiniCart',
style: {position: 'absolute', top:'690px', left:'100px', zIndex: '999', textAlign: 'left' }
}, document.body);

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.
