js創建post請求

/**js提交post請求：隱藏請求參數**/
function postDetail(URL, PARAMTERS) {
    //創建form表單
    var temp_form = document.createElement("form");
    temp_form.action = URL;
    //如需打開新窗口，form的target屬性要設置為'_blank'
    temp_form.target = "_blank";
    temp_form.method = "post";
    temp_form.style.display = "none";
    //添加參數
    for (var item in PARAMTERS) {
      var opt = document.createElement("textarea");
      opt.name = PARAMTERS[item].name;
      opt.value = PARAMTERS[item].value;
      temp_form.appendChild(opt);
    }
    document.body.appendChild(temp_form);
    //提交數據
    temp_form.submit();
  }

//調用

//var param = new Array();
//param.push({ "name":"id","value":"id123"});

//var serverUrl = "/a/save";
//postDetail(serverUrl,param);
