来自referrer的Regexp JS

Question

我需要检查推荐人是否有单词“profile”我需要将profile /(.*？）放在var中。我怎么能在js中做到这一点？

<script type="text/javascript">
var ref = document.referrer;
if( ~ref.indexOf("profile") ) {
  alert('coincidence found!');
}

 </script>

Answer 1

<script>
var str="Is this all there is?";
var patt1=/[^a-h]/g;
document.write(str.match(patt1));
</script>

结果：I，s，t，i，s ,, l，l，t，r ,, i，s，？

检查link The [^abc] expression is used to find any character not between the brackets.

这太过link

Answer 2

var ref = document.referrer;
ref.match(/(?:profile).+/,(match)=> {
    console.log(match)
})
