提取url字段
获取浏览器地址:var url = window.location.href;
判断地址中是否存在某字段:
例如:http://localhost:36666/ChooseClientView?key=A8D2DB67-952B-4BB2-A0F1-4BB083CFB55B&search=上海
window.location结构:
var url = window.location.href; if (url.indexOf("search") != -1) { var params = (function () { var search = location.search; var params = {}; if (search != "") { search.slice(1).split("&").forEach( function (val) { var arr = val.split("="); params[arr[0]] = arr[1]; } ); } return decodeURI(params.search); })();
if (url.indexOf("search") != -1) //如果url中存在search
var search = location.search; //?key=A8D2DB67-952B-4BB2-A0F1-4BB083CFB55B&search=%E4%B8%8A%E6%B5%B7
search.slice(1)//截取字符串,结果为key=A8D2DB67-952B-4BB2-A0F1-4BB083CFB55B&search=%E4%B8%8A%E6%B5%B7
search.slice(1).split("&")//用于把一个字符串分割成字符串数组。结果为:["key=A8D2DB67-952B-4BB2-A0F1-4BB083CFB55B", "search=%E4%B8%8A%E6%B5%B7"]
search.slice(1).split("&").forEach(
function (val) {
var arr = val.split("=");
params[arr[0]] = arr[1];
}
);
//结果为{key: "A8D2DB67-952B-4BB2-A0F1-4BB083CFB55B", search: "%E4%B8%8A%E6%B5%B7"}
return decodeURI(params.search);//将乱码转为汉字结果为 上海
