[英]Uncaught TypeError: undefined is not a function in extjs4?
I am working in extjs4 MVC, where I have a problem when I am storing data using a local storage, and I am going to change the proxy type dynamically from ajax to localStorage. 我正在extjs4 MVC中工作,当我使用本地存储存储数据时遇到问题,并且我打算将代理类型从ajax动态更改为localStorage。
After setting the data to localstorage I got a error Uncaught TypeError: undefined is not a function. 将数据设置为localstorage后,出现错误Uncaught TypeError:undefined不是函数。
My model: 我的模特:
Ext.define('Am.model.sn.UserModel',{
extend: 'Ext.data.Model',
//idproperty:'userId',//fields property first position pk.
fields: ['userId','firstName','middleName','lastName','languageId','primaryEmail','birthDate','password','securityQuestionId','securityQuestionAnswer','isMale','creationTime','ipAddress','confirmationCode','userStatusId']
});
My controller: 我的控制器:
Ext.define('Am.controller.sn.UserController1',
{
init:function()
{
console.log('Initialized Users! This happens before the Application launch function is called');
this.control(
{
...
});
},
remeberMe : function()
{
console.log("check box selected");
var email=this.getUserName().getValue();
var password=this.getPassword().getValue();
console.log("email="+email);
var objCheckBox=Ext.getCmp('checkbox');
if(objCheckBox.getValue()==true)
{
window.localStorage.clear();
// Here I am getting error Uncaught TypeError: undefined is not a function
var lsProxy = new Ext.data.proxy.LocalStorage({
id: 'localp',
type:'localstorage',
});
var modelObject = Ext.ModelManager.create(
{
primaryEmail:email,
password: password,
proxy:lsProxy
}, 'Balaee.model.sn.UserModel');
modelObject.setProxy(lsProxy);
modelObject.save();
} else {
console.log("check box is not selected");
}
},
});
Please give me suggestion... 请给我建议...
First off, if I understand your code correctly - you are loading the users and their passwords to the client side. 首先,如果我正确理解您的代码-您正在将用户及其密码加载到客户端。 This is a massive security risk as anyone can see this data (with a few mouse clicks).
这是一个巨大的安全风险,因为任何人都可以看到此数据(只需单击几下鼠标)。
Second, LocalStorage
doesn't have a type
config. 其次,
LocalStorage
没有type
配置。
Third, if you are really getting the error on this line (and not some sub line in the call stack): 第三,如果您确实在此行(而不是调用堆栈中的某些子行)中收到错误:
var lsProxy = new Ext.data.proxy.LocalStorage({
Than it can only be that the Ext.data.proxy
is not in scope. 只能是
Ext.data.proxy
不在范围内。
Try to add to your controller this config: 尝试将以下配置添加到您的控制器:
requires: ['Ext.data.proxy.LocalStorage'],
Let us know what happens. 让我们知道会发生什么。
