获取地址栏传过来的参数

//获取地址栏参数，name:参数名称
 function getUrlParms(name){
   var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)");
   var r = window.location.search.substr(1).match(reg);
   if(r!=null)
   return unescape(r[2]);
   return null;
   }
var id = getUrlParms("id");
上述方法可以获取地址栏传过来的id，还可以这样写
function getRequest() {
  var url = window.location.search; //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]]=decodeURI(strs[i].split("=")[1]);
      
    }
  }
  return theRequest;
}
var id= getRequest().id;

第二种可以取出中文：

function getParams() {
    var url = location.search; //获取url中"?"符后的字串
    var obj= {};
    if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for (var i = 0; i < strs.length; i++) {
            obj[strs[i].split("=")[0]] = (strs[i].split("=")[1]);
        }
    }
    return obj;
}
　

function getParams(){
    var obj = {};
    var keyvalue = [];
    var key = "",value = "";
    var url=window.location.href;
    var paraString = url.substring(url.indexOf("?") + 1, url.length).split("&");
    for (var i in paraString) {
        keyvalue = paraString[i].split("=");
        key = keyvalue[0];
        value = keyvalue[1];
        obj[key] = value;
    }
    return obj;
}
