Code
The script is really very simple. Text field must have unique identifier, this indentifier will be passed to the SelectAll() function. The function call only two methods: focus() and select().
<script type="text/javascript">
function SelectAll(id)
{
document.getElementById(id).focus();
document.getElementById(id).select();
}
</script>
Textarea:<br>
<textarea rows="3" id="txtarea" onClick="SelectAll('txtarea');" style="width:200px" >This text you can select all by clicking here </textarea>
Input TextBox:<br>
<input type="text" id="txtfld" onClick="SelectAll('txtfld');" style="width:200px" value = "This text you can select all" />
