Hello, it's been a while since i posted on here.

I was wondering if it is possible to get the element id by the tag of html.

So if i have a page like,

<div align="center"><tag>Test</tag><div>Test</div></div>

the javascript will only pick up the <tag> tags, correct?




my current code looks like this:

function toggleEditor(id) {
	var elm = document.getElementById(id);

	if (tinyMCE.getInstanceById(id) == null)
		tinyMCE.execCommand('mceAddControl', false, id);
	else
		tinyMCE.execCommand('mceRemoveControl', false, id);
}

i want to get all id's by there tag. So how?

You need to add an id to the element you want to find.
Your element "tag" have none here.

<div align="center">
  <tag id="thisIsMyId">Test</tag>
  <div>Test</div>
</div>

function toggleEditor(id) {
	var elm = document.getElementById('thisIsMyId');

	if (tinyMCE.getInstanceById(id) == null)
		tinyMCE.execCommand('mceAddControl', false, id);
	else
		tinyMCE.execCommand('mceRemoveControl', false, id);

}
Then only you can use an getElementById('thisIsMyId'); to get the reference to the element back.
Otherwise, you must ask the DOM to get every nodes of type "tag", and parse them in a loop to try to find the one you want, but it's way more complicated than using getElementById()....

no i don't want to use an id, thats what i am asking how to do. I want to get the element by its tag. Or can i get id by multiple id's like (firstid, secondid, thirdid)

Then you need to use the DOM.

What you'll need is getElementsByTagName().
It will return you an array of references to the tag you want, and you'll need to parse them.
http://developer.mozilla.org/en/docs...mentsByTagName

// check the alignment on a number of cells in a table.
var cells = document.getElementsByTagName("td");
for (var i = 0; i < cells.length; i++) {
status = cells[i].getAttribute("status");
if ( status == "open") {
// grab the data
}

}

Just get the total number of elements, then loop through them to get their corresponding ID's.

total = document.getElementById(formname).elements.length; //total elements

//suss out the form
for(x=0;x<total;x++){
    alert(document.getElementById(formname).elements[x].id); //display the ID for this element
    }
}

Cheers.
