前端笔记——获取url里面的参数值

备注

var url=window.location.href;//获取地址栏 url 
var index=url.indexOf('#');//获取#的位置 
var paramVal=url.substr(index,url.length);//获取 # 后面所有字符串

html

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
	<title>无标题</title>
</head>
<body>
	<script type="text/javascript" src="js/jquery-1.12.1.min.js"></script>
	<script type="text/javascript">
		$(function(){

			var a = 'https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Data_structures?userName=mona&pwd=3';

			var b = a.split('/');

			console.log(a);

			function parseParmStr(parmStr){

				if(parmStr.indexOf("?")!=-1){
					var index = parmStr.indexOf('?');
					var parms = {};					
					    parmStr = parmStr.substr(index+1);					
					    strs = parmStr.split('&'); //["userName=mona", "pwd=3"]

					for(var i=0;i<strs.length; i++){
							parms[strs[i].split('=')[0]] = strs[i].split('=')[1];
					}
				}
				

				return parms;
			}

			
			console.log(parseParmStr(a));

		})
