javascript에서 파라미터만 잘라서 사용 할 때 사용

<script>
    var test = location.search;
    console.log('test',test);

    function getParameterByName(name) {
        name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
        var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
            results = regex.exec(location.search);
        return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
    }

    var patId = getParameterByName('id'); // 1060192
    console.log('patId',patId);

</script>
