# Tabb i <textarea>

## #1 — Marcus, 2002-11-05T20:32Z

Hej

Någon som vet hur man gör så att tabbtangenten betyder tabb i en \<textarea\>? Jag vill alltså INTE hoppa till nästa objekt utan skapa en tabb. 

Tack på förhand

Jag vet inte om det går ...inte med HTML iaf.
Man skulle ju kunna använda **OnKeyUp** i JavaScript.....kanske ;)

Jag hittade följande funktioner som hjälpte bra...

```php
function CheckTab(el) {
	  if ((document.all) && (9==event.keyCode) && (event.ctrlKey)) {
		el.selection=document.selection.createRange(); 
		setTimeout("ProcessTab('" + el.id + "')",0)
	  }
	}

	function ProcessTab(id) {
	  document.all[id].selection.text=String.fromCharCode(9)
	  document.all[id].focus()
	}
```
