我正在使用Sencha Touch 2创建登录系统。提交表格时出现问题。它没有从服务器获取响应数据。下面是我的代码
Controller:
Ext.define("MyMobile.controller.LoginController", {
extend: "Ext.app.Controller",
views: ['LoginView'],
config: {
refs: {
loginForm: "#loginFormPanel"
},
control: {
'button[action=login]': {
tap: "authenticateUser"
}
}
},
authenticateUser: function (button) {
this.getLoginForm().submit({
url: 'login/authenticate',
method: 'POST',
success: function (form, result) {
debugger; //This block of code is not executing even after JSON response
var jsonoutput = Ext.decode(result); // json parsing
Ext.MessageBox.alert('Error', "Success");
},
failure: function (form, result) {//This block of code is not executing even after JSON response
Ext.MessageBox.alert('Error', "Invalid username/password");
}
});
}
});
查看
Ext.define("MyMobile.view.LoginView", {
extend: "Ext.form.FormPanel",
alias: "widget.mylogin",
id: 'loginFormPanel',
config: {
margin: '0 auto',
name: 'loginform',
frame: true,
url: 'login/Authenticate',
title: 'Login',
items: [
{
xtype: 'fieldset',
itemId: 'LoginFieldset',
margin: '10 auto 0 auto ',
title: '',
items: [
{
xtype: 'textfield',
label: 'User Name',
name: 'my-username',
required: true,
placeHolder: 'Username'
},
{
xtype: 'emailfield',
label: 'Email',
name: 'Email'
},
{
xtype: 'passwordfield',
label: 'Password',
name: 'my-password',
required: true,
placeHolder: 'Password'
}
]
},
{
xtype: 'button',
id: 'loginButton',
margin: '25 auto 0 auto ',
style: '',
maxWidth: 200,
ui: 'action',
width: '',
iconCls: 'user',
iconMask: true,
text: 'Login',
action: 'login'
}
]
}
});
App.JS
Ext.application({
name: "MyMobile",
appFolder: "myapp",
controllers: ["LoginController"],
views: ['LoginView'],
launch: function () {
var loginPanel= Ext.create('Ext.Panel', {
layout: 'fit',
items: [
{
xtype: 'mylogin'
}
]
});
Ext.Viewport.add(loginPanel);
}
});
有人可以找出问题所在吗?
下面是我从服务器获得的JSON响应。
{“ UserName”:“ Murali”,“ isAdmin”:true,“ isAuthenticated”:true}
即使获得JSON和200 OK的结果,我的代码表单提交功能也会进入失败回调。在失败回调函数failure:function(form,result)中,我将结果参数作为JSON。但是为什么它失败了?
让您的服务器返回如下所示的JSON响应:
如果成功:
{
"success":true,
"UserName":"Murali",
"isAdmin":true,
"isAuthenticated":true
}
如果失败:
{
"success":false
}
