I've created buttons to pop in a standardized url format for a link....

function ussellerlink() {
	var text = getText();
		AddTxt="http://www.ebay.com/sch/m.html?_nkw=&_sop=10&_ssn=";
		AddText(AddTxt);
	}		


It works great with one little nuisance. The curser always end up in the middle of the inserted link. Can I do something to the js to force the cursor to the end?

TIA.

The AddText() js function is the function that actually does the inserting. Can we take a look at that?

Ah. Interesting, didn't realize that. I may have to clone it then and rename it. I don't want it affecting everything else.


   function AddText(text) {

	var crtScrollTop;
	var crtScrollLeft;
	try {
		var tarea = document.PostTopic.Message;
		if (typeof tarea.scrollTop != 'undefined') {
			crtScrollTop = tarea.scrollTop;
			crtScrollLeft = tarea.scrollLeft;
		}
	} catch (e) {};

	var tarea = document.PostTopic.Message;
	if (typeof tarea.selectionStart != 'undefined')
	{ // if it supports DOM2
		start = tarea.selectionStart;
		end = tarea.selectionEnd;
		tarea.value = tarea.value.substr(0,tarea.selectionStart)
			+ text + tarea.value.substr(tarea.selectionEnd);
		tarea.focus();

		if (start === end )
		{
			res = text.split("/");
			if (res.length > 1)
			{
				tarea.selectionStart = start + (text.length) / 2;
				tarea.selectionEnd = tarea.selectionStart;
			}
			
		}
		else
		{
			tarea.selectionStart = ((start - end) == 0) ? start + text.length : start;
			tarea.selectionEnd = start + text.length;
		}
	} 
	else 
	{
		if (tarea.createTextRange && tarea.caretPos) {
			var caretPos = tarea.caretPos;
			caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ?   text + ' ' : text;
		}
		else {
			tarea.value += text;
		}
		tarea.focus(caretPos);
	}

	try {
		var tarea = document.PostTopic.Message;
		if (typeof tarea.scrollTop != 'undefined') {
			tarea.scrollTop = crtScrollTop;
			tarea.scrollLeft = crtScrollLeft;
		}
	} catch (e) {}; 
}



Or maybe come up with a new function just for this?

Your AddText function is slightly different to the default AddText the behaviour of which I'm pretty certain places the cursor after the inserted text.

Do you know what MOD you installed that changed your AddText function?

Honestly Hu, it could be any of dozens of things we've changed. We are incredibly modded.

Maybe I'll grab it from a fresh download and rename it, then see if that works.

yep, would be worth it, just give the original function a different name and call that one from your code see if it works

Works like a charm.

It's much smaller than my current one.

Thanks!
