Hi Frank, Use javascript method indexOf() as follow. <script type="text/javascript">
var str = "nice one code";
var substr = "nice";
var IsSubstringExists = false;
if (str.indexOf(substr) >= 0) {
IsSubstringExists = true;
} else {
IsSubstringExists = false;
}
alert(IsSubstringExists);
</script>
The indexOf() method returns the position of the first occurrence of a specified value in a string.
