Question

I’m adding some javascript validation to a form. The form has fields that currently look like:

<input name="Employee Full Name" value="" type="text" id="Employee Full Name" size="30" maxlength="50" style="width:300px;">

I am trying to access the values of the fields, but I seem to be doing it incorrectly with the spaces in the input name, is there a way to escape?

if (theForm.Employee Full Name.value == ""){   
   alert("Please enter a value for the \"Employee Full Name\" field.");     
   theForm.Employee Full Name.focus();   
   return (false);   
}

You can use the bracket notation for objects as well as arrays:

theForm['Employee Full Name'].value == ""

This allows you to access attributes where the names are invalid in a . notation syntax:

foo.1 //foo['1']
foo.this-is-wrong //foo['this-is-wrong']
foo.bar.baz //although this looks correct, it's wrong if you actually wanted foo['bar.baz']
