Hello,
I need to know how to create closing tag elements when using DOM to add in form elements to a page.
Here is the code...the <div> I am adding to the page is called dropDownList (for legacy reasons...it isnt really a drop down list!).
I need to put in closing td tags...
I tried this: - var tdClose = document.createElement(/td);
and this: - var td = document.createElement('/td');
but when I try and add them e.g. - document.getElementById('dropDownList').appendChild(tdClose);
I get errors.
Help ! - function addRaresToList(number){
-
var species = document.getElementById('addSpecies').value;
-
alert ("ADD " + species + " to " + number);
-
-
var td = document.createElement(td);
-
-
// add hidden index
-
var i = document.createElement('input');
-
i.type = 'hidden';
-
i.name = 'observation.index';
-
i.value = 'number';
-
document.getElementById('dropDownList').appendChild(i);
-
-
// add hidden comment
-
var i = document.createElement('input');
-
i.type = 'hidden';
-
i.name = 'observation.number.comment';
-
i.id = 'observation.number.comment';
-
document.getElementById('dropDownList').appendChild(i);
-
-
// add hidden breeding code
-
var i = document.createElement('input');
-
i.type = 'hidden';
-
i.name = 'observation.number.breedingCode';
-
i.id = 'observation.number.breedingCode';
-
document.getElementById('dropDownList').appendChild(i);
-
-
// add species name
-
document.getElementById('dropDownList').appendChild(td);
-
var txt = document.createTextNode(species);
-
document.getElementById('dropDownList').appendChild(txt);
-
-
-
// add checkbox
-
document.getElementById('dropDownList').appendChild(td);
-
var i = document.createElement('input');
-
i.type = 'checkbox';
-
i.name = 'observation.number.species';
-
var d = document.getElementById( 'dropDownList' );
-
d.appendChild( i );
-
-
// add textbox
-
document.getElementById('dropDownList').appendChild(td);
-
var i = document.createElement('input');
-
i.type = 'text';
-
i.name = 'observation.number.speciesCode';
-
i.size = '7';
-
i.maxlength = '7';
-
var d = document.getElementById( 'dropDownList' );
-
d.appendChild( i );
-
-
}
-

You don't need a closing tag. The object is created and you can append it to the row and append elements/items to it.

I am still a bit confused..
Do I need to make a table in my javascript ?
At the moment all the elements I am adding in are going into just one cell of a table (I am adding my <div> to an existing table). I want each element (text, checkbox, input text) to go into a separate cell.
Surely to do that I need to put a </td> in somewhere...and I can't do this: - var tdClose= document.createElement('/td');
-
document.getElementById('dropDownList').appendChild(tdClose);
by 'the object is created' do you mean the var d = document.getEle mentById( 'dropDownList' ); object ? Sorry to be so dim, I am very new to this !
thanks for your input

hi ...
nope ... when using createElement it creates a valid node for you. when you append another node to it, it will be a childNode of it ... so you don't need to create a closing tag. you are not creating tags! but nodes with this dom-method.
kind regards
ps: may be the following small graph is of help ... imagine a document as a tree: - html - root node (starts with <html> and ends with </html>)
-
|_ head
-
|_ body
-
|_ div1
-
|_ div2
-
|_ whatever nodes ...

Gits is right, i think you might have confused document.write and document.create Element.

Hi,
Got a litte problem here. I'm trying to create a XSLT file that will do
a transformation from WordML format (MS Word XML format, see
http://rep.oio.dk/Microsoft.com/officeschemas/welcome.htm) to a
reasonably clean (X)HTML format.
(The reason being that, combined with some PHP scripting it should be
possible to store the embedded images, which is pretty neat).

I've done some research online and turned up with results that did not sit well with me. I’m using the System.Xml.XslCompiledTransform class as recommended by MS; however, it’s creating self-closing tags that I don’t want, example:

* Using the XslCompiledTransform class I get: <script language="javascript" src="client_scripts/VehInInv.js"/> -- notice...

Hello all, I have been trying to implement a script using which when
the user clicks on one of the two span tags, its text is highlighted
while the same happens when the user clicks on the second one, except

code doesn't work.

Hi,
I have a VB.NET (VS2005, .NET 2.0) application producing an XML file which
is then used by a third-party product. It turns out the latter doesn't like
self-closing tags (i.e. it would rather see <CardNo></CardNothan <CardNo
/>).
Is there a simple way to tell the XMLDocument to use the "traditional" way
of showing an empty tag instead of always saving self-closing tags?

I am using the System.Web.UI.HtmlTextWriter, and would like to create tags
that are self-closing (such as <tagname />). The RenderBeginTag method does
not offer the option of making a self-closing tag (I think it should have an
optional boolean parameter to specify whether it is self-closing, but it
doesn't). I know how to make self-closing tags using the Write methods, but
this requires calling a write method for every attribute and style,...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
