var url = window.location.href; //获取当前窗口的Url; 结果:http://localhost:61768/Home/Index?id=2&age=18 var host = window.location.host;//获取当前窗口的主机名; 结果:localhost:61768 var port = window.location.port; //获取当前窗口的端口; 结果:61768 var pathname = window.location.pathname;//获取当前窗口的路径 ; 结果:/Home/Index var URL = document.URL;//获取当前文档的Url;结果:http://localhost:61768/Home/Index?id=2&age=18 var search = window.location.search;//获取参数;结果:?id=2&age=18
分割url提取参数
var search = window.location.search; var age = getSearchString('age', search); //结果:18 var id = getSearchString('id', search); //结果:2 //key(需要检索的键) url(传入的需要分割的url地址,例:?id=2&age=18) function getSearchString(key, Url) { var str = Url; str = str.substring(1, str.length); // 获取URL中?之后的字符(去掉第一位的问号) // 以&分隔字符串,获得类似name=xiaoli这样的元素数组 var arr = str.split("&"); var obj = new Object(); // 将每一个数组元素以=分隔并赋给obj对象 for (var i = 0; i < arr.length; i++) { var tmp_arr = arr[i].split("="); obj[decodeURIComponent(tmp_arr[0])] = decodeURIComponent(tmp_arr[1]); } return obj[key]; }
