if ( re.ignoreCase ) {
document.write("Test1-ignoreCase property is set");
} else {
document.write("Test1-ignoreCase property is not set");
}
re = new RegExp( "string", "i" );
if ( re.ignoreCase ) {
document.write("<br/>Test2-ignoreCase property is set");
} else {
document.write("<br/>Test2-ignoreCase property is not set");
}
</script>
</body>
