You can also use FilteredTextBoxExtender control from AjaxControlToolkit. It will ease your application's maintenance if you need to change or add other forbidden characters some day.

See example here: FilteredTextBox Sample

    $('INPUT[type=text]').keypress(function(e) {

                   if (window.event) 
                       keycode = window.event.keyCode;
                   else if (e) 
                       keycode = e.which;
                   else return true;

                   if ((keycode == 32) ) //Space KeyCode
                   {
                       return false;
                   }
                   else {
                       return true;
                   }

               });

Use Javascript code as below:

<input type="text" name="myText" onKeypress="if (event.keyCode == 32) event.returnValue = false;"/>

tested in Internet Explorer
