js獲取url，截取url參數，截取url後文件名

獲取當前:

var url = window.location.href;

 百度爲例：

var url=window.location.href;
console.info(url);
http://www.jspp.cn/testbin/apptest/app-site/explore.html;

split() 方法用於把一個字符串分割成字符串數組。 

先用split('?')把URL和參數分離： 

var url=window.location.href;
var urlArr = url.split('?');
　　console.info(urlArr);

["http://www.jspp.cn/testbin/apptest/app-site/explore.html"]

 

var url=window.location.href;var urlArr = url.split('?');
var k = urlArr[0], appU = k.split('/');
console.log(k);
console.log(appU);
獲得:
VM363:1 http://www.jspp.cn/testbin/apptest/app-site/explore.html
["http:", "", "www.jspp.cn", "testbin", "apptest", "app-site", "explore.html"]

0：」http:"
1:""
2:"www.jspp.cn"
3:"testbin"
4:"apptest"
5:"app-site"
6:"explore.html"
length:7

 直接那數組最後一個就是文件名：

var L = appU[appU.length - 1];

console.log(L);//拿到當前頁名稱 判斷傳遞參數獲得："explore.html"
