Javascript problem?

[Evan]

This script is suppose to check to see if a date is correctly entered. It doesnt work.

Anyone see how to fix it?

if (tempobj.name.substring(0,7)=="reqdate") {
            if (tempobj.type=='text') {
                var splitted = tempobj.value.match("/\[\d{1,4}\.\d{1,4}\.\d{1,4}\]$/");
                if(splitted == null) {
                    pass=false;
                }
            break;
            }
        }
