为求助：为什么form提交一直执行faliure，而服务器返回的是{success:true}

服务器段代码执行了，执行这句：response.getWriter().println("{success:true,msg:'添加成功'}");

[clz2008wan]

回调函数怎么执行：
failure : function(form, action) {
Ext.MessageBox.alert('添加信息失败', action.result.msg);
form.reset();

}
而且action.result.msg也去不到值

[licip]

failure : function(form, action) {
Ext.MessageBox.alert('添加信息失败', action.result.msg);
form.reset();

}
显示的是这个吗？你的服务器端的代码有执行吗？

ajax连接出什么问题了，如果超时，是什么原因引起的，谢谢你解答

[豆虫]

回调走failure的情况是ajax连接出问题了 比如说超时这种情况等等 才会走到failure 否则都会走success 和后台返回的东西无关

把后台的代码贴出来一些

String address=request.getParameter("address");
if(number!=""){
response.getWriter().println("{success:true,msg:'添加成功'}");

}

response.getWriter().println("{success:false,msg:'添加失败'}");

if(number!=""){
response.getWriter().println("{success:true,msg:'添加成功'}");

}

response.getWriter().println("{success:false,msg:'添加失败'}");

问题在这里吧 可能表单里面别的字段有错误，而你只判断了number
