我正在开发一个简单的登录页面,其中我需要将任何用户在用户名字段中输入的值与单击“登录按钮”时的 json 数据存储进行比较。我的问题是,我们可以从数组中的 json 存储中获取用户名列表并与文本字段值进行比较吗?如果是这样,怎么做?
我的 nSpaceIndex.html
<html>
<head>
<title>nSpace | Expense / Project Solutions</title>
<link rel="stylesheet" type="text/css" href="extjs/resources/css/ext-all.css">
<script type="text/javascript" src="extjs/ext-debug.js"></script>
<script type="text/javascript" src="app.js"></script>
</head>
<body>
</body>
</html>
应用程序.js:
Ext.application({
requires: ['Ext.container.Viewport'],
name: 'nSpace',
controllers: [
'nSpaceController'
],
appFolder: 'app',
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'fit',
items: {
xtype: 'loginView'
}
});
}
});
我的 nSpaceController.js:
Ext.define('nSpace.controller.nSpaceController', {
extend: 'Ext.app.Controller',
stores: [
'Users'
],
views: [
'login.loginView'
],
model: 'loginModel',
init: function() {
this.control({
"#loginButton": {
click: this.onLoginButtonClick
}
});
},
onLoginButtonClick: function(){
//var jsonArray = store.Users.data.items
//console.log(jsonArray);
// I NEED TO GET THE REFERENCE OF MY STORE: USERS TO COMPARE
var logUserName = Ext.getCmp('getUserName').getValue();
var logPassword = Ext.getCmp('getPassword').getValue();
if(logUserName == 'user01' && logPassword == 'password01'){
Ext.MessageBox.show({title: 'Success', msg: 'You will be redirected to the home page in few moments...', icon:Ext.MessageBox.INFO});
}
else if(logUserName == 'user02' && logPassword == 'password02'){
Ext.MessageBox.show({title: 'Success', msg: 'You will be redirected to the home page in few moments...', icon:Ext.MessageBox.INFO});
}
else{
Ext.MessageBox.show({title: 'OOPS!!!', msg: 'Please Enter Valid Details', icon:Ext.MessageBox.WARNING});
}
},
});
我的 loginModel.js:
Ext.define('nSpace.model.loginModel', {
extend: 'Ext.data.Model',
fields: ['loginusername', 'password']
});
用户.js:
Ext.define('nSpace.store.Users', {
extend: 'Ext.data.Store',
model: 'nSpace.model.loginModel',
autoLoad : true,
proxy: {
type: 'ajax',
url: 'data/users.json',
reader: {
type: 'json',
root: 'users',
successProperty: 'success'
}
}
});
登录视图.js:
Ext.define('nSpace.view.login.loginView' ,{
extend: 'Ext.form.Panel',
alias: 'widget.loginView',
store: 'Users',
title: 'nSpace | Login',
frame:true,
bodyPadding: 5,
width: 350,
layout: 'anchor',
defaults: {
anchor: '100%'
},
defaultType: 'textfield',
items: [{
fieldLabel: 'User Name',
name: 'loginusername',
id: 'getUserName',
allowBlank: false
},{
fieldLabel: 'Password',
inputType: 'password',
id: 'getPassword',
name: 'password',
allowBlank: false
}],
// Reset and Submit buttons
buttons: [{
text: 'Sign Up',
handler: function() {
// location.href = 'signUp.html';
}
},{
text: 'Reset',
handler: function() {
this.up('form').getForm().reset();
}
}, {
text: 'Login',
id:'loginButton',
formBind: true, //only enabled once the form is valid
disabled: true,
}],
renderTo: Ext.getBody()
});
用户.json:
{
"success": true,
"users": [
{"loginusername": 'user01', "password": 'password01'},
{"loginusername": 'user02', "password": 'password02'}
]
}
