两个特别常用的JS函数

 //对象追加到url作为参数

function queryString(url, query) {
  let str = []
  for (let key in query) {
    str.push(key + '=' + query[key])
  }
  let paramStr = str.join('&')
  return paramStr ? `${url}?${paramStr}` : url
}

例如：

queryString('http://192.168.1.32:3638/checkout',{abc:123,fd:"dffd",fd:2121})

//获取url中"?"符后的字串转对象

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

例如：

GetRequest("http://192.168.1.32:3638/checkout?abc=123&fd=2121")
