Javascript comparison operator but IGNORE case-sensitivity?

[monaya]

I'm comparing two textfields with something like

if (document.form1.code.value != "FRNretrt83473")

Can the comparison be fixed to ignore case sensitivity.

Thanks.

have you tried the toLowercase() method?

I agree with you thenajsays this is the right function to use.

I would change the function like this for clarity.

var fieldvalue= document.form1.code.value.toLowerCase();
if (fieldvalue != "frnretrt83473") {

String.prototype.equalTo = function( str )
{
  return this.toLowerCase() === str.toLowerCase();
}


if( document.form1.code.value.equalTo( "FRNretrt83473" ) )
