Javascript equalsIgnoreCase Function

This week's code sample is JAVASCRIPT based. I found this while researching user validation routines. This function is a javascript version of a common Java function. We have replicated the calling syntax as a java programmer would expect to use it by effectively appending it as a method of the javascript String Object.

For more great scripts: http://www.apriori-it.co.uk

Important Note: Works with IE and FireFox

  
//The first line assigns the MatchIgnoreCase function as
//an equalsIgnoreCase method of the String object
String.prototype.equalsIgnoreCase=MatchIgnoreCase;

function MatchIgnoreCase(strTerm, strToSearch)
{
strToSearch = strToSearch.toLowerCase(); strTerm = strTerm.toLowerCase();
if(strToSearch==strTerm)
{
return true;
}
else
{
return false;
}
}
