Javascript获取地址栏（URL）参数信息

1. 获取全部的参数信息

function(url) { //从给定的地址或者默认的地址栏中获取全部的参数

var vars = {},

hash;

var hashes = null;

if (!url)

url = window.location.search;

hashes = url.slice(url.indexOf('?') + 1).split('&');

for (var i = 0; i < hashes.length; i++) {

hash = hashes[i].split('=');

if (!!hash && hash[0].length > 0)

vars[hash[0]] = hash[1];

}

return vars;

}

2. 获取指定的参数信息

function(name) {//从浏览器的地址栏中获取指定的参数的值

name = name.replace(/[\[]/, '\\[').replace(/[\]]/, '\\]');

var regex = new RegExp('[\\?&]' + name + '=([^&#]*)');

var results = regex.exec(window.location.search);

return results === null ? '' : results[1].replace(/\+/g, ' ');

}
