Question

To avoid typing multiple spaces in text area I’m calling a function on onCLick, on keyup and written the code below

var val = document.getelemntByID('trmp');
val.value = val .value.replace(/ +(?= )/g,'');

this is working fine in Firefox, in IE7 it’s working, but causing some other problem, like select a word and delete it will delete entire text area content

Answer 1

Use the regex only for space.Add a keycode condition.
