//规则模型，方便序列化 var ruleModel = { Name: id, Type: "GridLookup", Value: value } showRule.push(ruleModel); }) var json = JSON.stringify(showRule); //json序列化 var rule = encodeURI(json); //url加密 //创建form var temp = document.createElement("form"); temp.action = "View.aspx?Bm=" + bm; temp.method = "post"; //创建隐藏域 var myInput = document.createElement("input"); myInput.setAttribute("name", "Value"); myInput.setAttribute("value", rule); myInput.setAttribute("type", "hidden"); temp.appendChild(myInput);
document.body.appendChild(temp); temp.submit(); //提交表单 document.body.removeChild(temp); //移除Form
//$.post("View.aspx?Bm=" + bm, { Value: rule }); //JQpost 异步 无刷新 } 注：JQ的 get post ajax 方法
