在jQuery中直接提交表单后怎么获取返回值

Answer 1

定义一个：
<iframe id="file_upload_return" hidden="true" name="file_upload_return"></iframe> <!-- 提交表单处理iframe框架 -->
<form id="fileOperationsForm" name="fileOperationsForm" target="file_upload_return" enctype="multipart/form-data" method="post">
$("#file_upload_return").load(function(){//获取iframe中的内容
var body = $(window.frames['file_upload_return'].document.body);
var data = eval('(' + body[0].textContent + ')');
});

Answer 2

$('#myForm').ajaxForm(function(data) {
alert(data);//弹出ajax请求后的回调结果
});
