问题描述

如何在javascript中问号后获取url值?

How can I get the url value after a question mark in javascript?

我想要以下行为:

if value is yes then 10+2 
else if value is no then 10.

我想输出警告消息.

<div class="col-xs-4 col-sm-4 col-md-4 text-center width100">
    <a href="piccal.html" class="btn btn-success" id="yes">PIC Grant Calculator</a>
</div>
<div class="col-xs-4 col-sm-4 col-md-4 text-center width100">
    <a href="piccal.html" class="btn btn-danger" id="no">PIC Grant Calculator</a>
</div>

<script> 
if (value == no) {
    alert('hello');
}
</script>

<script> 
if (value == yes) {
    alert('hi');
}
</script>

推荐答案

使用以下代码:

var a = location.href; 
var b = a.substring(a.indexOf("?")+1);
