js中传递参数的方法总结（附代码）

<input type="hidden" name="tc_id" value="{{tc_id}}">

window['name'] = "the window object";

window.localStorage.setItem("name", "xiaoyueyue");
window.localStorage.getItem("name")

1、localStorage 是持久存储，不主动删除 一直存在  
         sessionStorage 是临时存储,关闭浏览器数据就没了
2、localStorage 可以多窗口共享
       sessionStorage 不能多窗口共享数据

function parseParam(url) {
  var paramArr = decodeURI(url).split("?")[1].split("&"),
    obj = {};
  for (var i = 0; i < paramArr.length; i++) {
    var item = paramArr[i];
    if (item.indexOf("=") != -1) {
      var tmp = item.split("=");
      obj[tmp[0]] = tmp[1];
    } else {
      obj[item] = true;
    }
  }
  return obj;

}

function GetQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if (r != null) return unescape(r[2]); return null;
}

<!--base-->
