Q1:通过正则获得url中的参数简单实例
url界面
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<a href="script05.html?name=zhang&age=12&sex=男">点击事件</a>
</body>
</html>
js中
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<script>
//console.log(location.href);
//console.log(location.search.substr(1));
//name=zhang&age=12&sex=男
/*通过正则获取url中的参数*/
function getUrlParam(name){
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r!=null)
return decodeURI(r[2]);
return null;
}
var name = getUrlParam("sex");
console.log(name);
</script>
</body>
</html>
结果
