Definition and Usage

The source property is used to return the text used for pattern matching.

The returned text is everything except the forward slashes and any flags.

Syntax

RegExpObject.source

In the following example we will get the text used for pattern matching:

<script type="text/javascript">
var str = "Visit W3Schools";
var patt1 = new RegExp("W3S","g");

document.write("The regular expression is: " + patt1.source);
</script>
