Handling a string with only blank space in required fields

[Martin Svensson]

When trying to submit a required textfield that just contains blank spaces. There comes an error message about invalid data that perhaps is difficult to understand for the common user. The message is: "Invalid use of null. The 'name' value cannot be set to null."

Perhaps a string with only spaces could be handled in the same way as an empty textfield/string.

I have added a JavaScript funtion to main library: Main.trimString() which trims a string from leading and trailing spaces.

Use like this:

if (Main.trimString(frm.name.value) == '')
{
   alert("You must enter a name");
   frm.name.focus();
   return false;
}
