订单的增加代码还有别的方法吗？

Question

<script type="text/javascript">

$(function(){

$("#save").click(function(){

var flag=$("#standardForm").form('validate');

if(flag){

var formData=$("#standardForm").serializeJSON()

$.post("../../stanstandardAction_save.action",formData,function(data){

if(data.success){

$("#standardWindow").window('close');          $("#grid").datagrid('reload'); }

$.messager.alert("提示",data.message);

},"json");

}});

});

</script>
