- Insert variable in command

[arfa]

I am modifying a small online text editor.
I have a series of dynamically generated fields: sub0 sub1 sub2 etc.

I get stuck feeding the modified data back.
subX.selection.setContent() - where X is the field number.

how can I set X as a variable?

[Padonak]

var s='sub'+X;
s.selection.setContent();

may be this way?

Thanks for the quick reply.
may be this way?
Yes.... and no.

the command subX.selection.setContent(); is a feed to the text editor js and subX seems not to be a variable but a literal string.
I tried: var test = 'sub0';
test.selection.setContent(); and it failed.

I tried 'test'.selection.setContent(); and it failed.
various other quote, bracket combinations - failed.

I will continue poking the dog.

you'd better show the whole code

If you show the precise HTML, I can be more precise, but one of the following:

document.getElementsByName("sub"+X).sel/*...*/; // probably
formName["sub"+X].sel/* ... */; // I haven't used this in a while, I think formName.inputName is valid.

FIRST - loop and create the buttons for each field that launch the picker.

the sub$i.selection.getText(); is text editor code.
sub$i is the bogey (in jscolor.js) we are trying to fix. see: "SECOND"

the hidden input is part of my (not yet successful) attempt to transfer the field# to jscolor.js
the second input is part of the color picker

<a class=pu onmousedown=\"document.getElementById('myColtx"; echo $i; 
	echo "').color.showPicker();sub$i.selection.getText();return false;\">
				<input type=hidden id=subnum value=\"$i\">
		<img style='padding:1 3 0 3' src=punymce/img/TXT_fill.gif id=txtfill$i></a>
	<input class=\"color {pickerClosable:true,required:false,styleElement:'txtfill"; echo $i; echo "'}\" 
		style=position:relative;top:14px;left:-9;width:2px;height:2px;border:2px;color:red id=myColtx$i value=''>

____________________
SECOND - in jscolor.js

p.btn.onmousedown = function () { // on clicking picker 'OK' button
// start my code
			var test = 'sub0';
		//	alert(test); // OK
				var punySEL = sub0.selection.getText(); // OK - BUT NEEDS '0' AS A VARIABLE???
						if (punySEL != '') {
				var txtcolor = document.getElementById('myColtx0').color; // '0' AS A VARIABLE???
	sub0.selection.setContent('<span style=color:#'+txtcolor+'>'+punySEL+'</span>'); } // '0' AS A VARIABLE???
// end my code
				THIS.hidePicker();

Yes, this works - - and it moves to my other question...

how to get the variable 'X' from the button code into the picker code?

in jscolor.js...
var X = document.getElementById('sub'+???).value;
I need the variable to get the variable.
