我有一个包含两个项目的视口:身份验证表单和选项卡面板。 在此视口的initComponent方法中,我调用一个函数来检查用户是否输入了他的登录名和密码。
如果没有,则会显示身份验证表单,当他点击登录按钮时,会显示选项卡面板。
但如果有存储的凭据,我希望应用程序自动切换到选项卡面板。
这就是我想要的方式:
app.views.Viewport = function (config) {
Ext.apply(this, config);
this.user = null; // Setter par le checkLogin !
this.bottomTabs = new Ext.TabPanel({
tabBar: {
dock: 'bottom',
layout: { pack: 'center' }
},
items:[...],
layout: 'fit',
cardSwitchAnimation: false,
});
this.userLogin = new app.views.UserLogin();
//constructor
app.views.Viewport.superclass.constructor.call(this, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'fade',
items: [
this.userLogin,
this.bottomTabs
]
});
};
Ext.extend(app.views.Viewport, Ext.Panel, {
initComponent: function () {
app.views.Viewport.superclass.initComponent.call(this);
this.initialCheck();
},
initialCheck: function(){
console.log('init');
var credentials = window.localStorage.getItem("neroApp_credentials");
if (credentials == null || credentials == "reset") {
console.log('no creds');
this.setActiveItem(this.userLogin); // ***
}
else {
console.log('creds');
Ext.Ajax.defaultHeaders = {'Authorization':"Basic " + credentials};
this.checkLogin();
}
},
checkLogin: function () {
console.log('checkLogin');
Ext.Ajax.request({
url: app.stores.baseAjaxURL + '&jspPage=%2Fajax%2FgetUser.jsp',
scope: this,
success: function(response, opts) {
console.log('success');
var user = Ext.decode(response.responseText);
this.user = user;
this.actualites.actualitesList.refreshActu(this.user, parseInt(window.localStorage.getItem("newsPerLoad")));
this.setActiveItem(this.bottomTabs, { type: 'fade', duration: 500 });
},
failure: function(response, opts) {
console.log('failure');
}
});
},
resetLogin: function() {
window.localStorage.setItem("neroApp_credentials", "reset");
Ext.Ajax.defaultHeaders = {'Authorization':"Basic RESET_Credentials"};
}
});
但由于 * 行,我在启动时遇到了白屏。我猜它太早了,可能因为checkLogin函数中的setActiveItem工作正常。
任何人都知道为什么这个setActiveItem会触发错误?

好吧,我没有发现问题是什么,即使我猜测在initComponent中触发setActiveItem并不是一个好习惯,但我终于通过设置活动项来实现它:
initialCheck: function(){
console.log('init');
var credentials = window.localStorage.getItem("neroApp_credentials");
if (credentials == null || credentials == "reset") {
this.activeItem = this.userLogin;
}
else {
this.activeItem = this.bottomTabs;
Ext.Ajax.defaultHeaders = {'Authorization':"Basic " + credentials};
this.checkLogin();
}
},
