JS解析URL參數並返回參數名字和參數值組成的JS對象

function sys_getUrlkey(url) {
  var params = {};
  try{
    var urls = url.split("?");                  console.log('1_分割url:', urls)
    var arr = urls[1].split("&");               console.log('2_分割urls[1]:', arr)
    for (var i = 0, l = arr.length; i < l; i++) {
      var a = arr[i].split("=");                console.log('3_遍歷 arr 並分割後賦值給a:', a[0], a[1])
      params[a[0]] = a[1];                      console.log('4_a給params對象賦值:', params)
    }
                                            console.log('5_結果:', params)
  }catch(e){}
  return params;
