我有一个带有几个视图的测试应用程序。我试图在我的按钮上调用一个简单的“点击”侦听器。即使控制器已实例化并启动,点击事件似乎也不会触发。
这是我的 app.js
Ext.application({
name: 'MyApp',
requires: [
'Ext.MessageBox',
'Ext.form.FormPanel',
'Ext.navigation.View'
],
views: [
'Main',
'Tasks'
],
controllers: [
'Main'
],
models: [
'Task',
'Schedule'
],
stores: [
'Tasks',
'Schedules'
],
launch: function() {
// Destroy the #appLoadingIndicator element
try{
Ext.fly('appLoadingIndicator').destroy();
}catch(err){
console.warn("[CUSTOMWARN]Could not destroy loading indicator because of -- \n"+err);
}
var DEBUG=false;
if(!DEBUG){
// Initialize the main view
Ext.Viewport.add(Ext.create('MyApp.view.Main'));
}
}
});
Main.js -- 控制器
Ext.define('MyApp.controller.Main', {
extend: 'Ext.app.Controller',
requires: [
'MyApp.view.Main'
],
init: function(){
// download and parse data from server here.
console.log('controller initiated!');
},
config: {
refs: {
loginBtn: 'button[action=login]'
},
control: {
loginBtn: {
tap: 'loginBtnHandler'
}
}
},
loginBtnHandler: function(){
this.callParent(arguments);
Ext.Msg.alert('here');
}
});
Main.js -- 查看
Ext.define('MyApp.view.Main', {
extend: 'Ext.navigation.View',
alias: 'customnavigationview',
requires: [
'MyApp.form.Login'
],
config: {
navigationBar: {
hidden: true
},
items: [
{
xtype: 'logincard',
flex: 1
}
],
}
});
Login.js -- 对于 xtype: 'logincard'
Ext.define('MyApp.form.Login', {
extend: 'Ext.form.Panel',
xtype: 'logincard',
requires: [
'Ext.field.Password',
'Ext.field.Email',
'Ext.form.FieldSet',
'Ext.field.Toggle',
'Ext.Label'
],
// id: 'loginForm',
config: {
items: [
{
xtype : 'label',
html : 'Login failed. Please enter correct credentials.',
itemId : 'signInFailedLabel',
hidden : true,
hideAnimation : 'fadeOut',
showAnimation : 'fadeIn',
style : 'color:#990000;',
margin : 10
},
{
title: 'Please log in',
xtype: 'fieldset',
items:[
{
xtype: 'textfield',
name : 'username',
label: 'UserName'
},
{
xtype: 'passwordfield',
name : 'password',
label: 'Password'
}
]
},
{
xtype: 'fieldset',
items: [
{
xtype : 'togglefield',
name : 'rememberLogin',
label : 'Remember Me '
}
]
},
{
xtype : 'button',
id : 'loginSubmitBtn',
itemId : 'loginSubmitItemBtn',
text : 'Login',
ui : 'action',
action : 'login',
margin : 10
}
]
}
});
任何帮助将不胜感激!
编辑:所以我尝试使用Ext.ComponentQuery.query("#loginSubmitBtn")
并在控制台上打印输出,我可以看到它指向正确的按钮。这是输出。
