获取url中参数值

方法一：

function GetRequest() {
var url = window.location.href; //获取url中"?"符后的字串
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for (var i = 0; i < strs.length; i++) {
theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1]);
}
}
return theRequest;
}
var Request = new Object();
Request = GetRequest();

var c = Request["想要的参数"]
console.log(c)

方法二：

function getUrlVars(name) {
  var vars = {};
  window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function (m, key, value) {
    vars[key] = value;
  });
  return vars[name];
}
