javascript - ExtJs 想在 Ext.onReady() 函数之后调用一些代码

Question

在 ExtJs 中，我们有一个名为 Ext.onReady() 的页面加载事件，它在 window.onload 之后被调用，因为它被注册到 onload 并被调用。所以基本上我们可以找到的最后一个事件是 Ext.onReady()。

问题是我有几个 Ext.onReady() 用于我们无法更改的业务需求。我有 ExtJs TabbedPanel，它被重新发送到页面的最后一个 Ext.onReady() 页面。

我想要的是在 TabbedPanel 呈现到页面后在其上注册一些事件。假设您无法控制 TabbedPanel 的呈现事件，并且您无法在页面的最后一个 onReady 之后创建 onReady。

Ext.require([
'Ext.window.MessageBox',
'Ext.tip.*'
 ]);

Ext.onReady(function(){
Ext.get('mb1').on('click', function(e){
    Ext.MessageBox.confirm('Confirm', 'Are you sure you want to do that?', showResult);
});

Ext.get('mb2').on('click', function(e){
    Ext.MessageBox.prompt('Name', 'Please enter your name:', showResultText);
});

Ext.get('mb3').on('click', function(e){
    Ext.MessageBox.show({
       title: 'Address',
       msg: 'Please enter your address:',
       width:300,
       buttons: Ext.MessageBox.OKCANCEL,
       multiline: true,
       fn: showResultText,
       animateTarget: 'mb3'
   });
});

Ext.get('mb4').on('click', function(e){
    Ext.MessageBox.show({
       title:'Save Changes?',
       msg: 'You are closing a tab that has unsaved changes. <br />Would you like to save your changes?',
       buttons: Ext.MessageBox.YESNOCANCEL,
       fn: showResult,
       animateTarget: 'mb4',
       icon: Ext.MessageBox.QUESTION
   });
});

Ext.get('mb6').on('click', function(){
    Ext.MessageBox.show({
       title: 'Please wait',
       msg: 'Loading items...',
       progressText: 'Initializing...',
       width:300,
       progress:true,
       closable:false,
       animateTarget: 'mb6'
   });

   // this hideous block creates the bogus progress
   var f = function(v){
        return function(){
            if(v == 12){
                Ext.MessageBox.hide();
                Ext.example.msg('Done', 'Your fake items were loaded!');
            }else{
                var i = v/11;
                Ext.MessageBox.updateProgress(i, Math.round(100*i)+'% completed');
            }
       };
   };
   for(var i = 1; i < 13; i++){
       setTimeout(f(i), i*500);
   }
});

Ext.get('mb7').on('click', function(){
    Ext.MessageBox.show({
       msg: 'Saving your data, please wait...',
       progressText: 'Saving...',
       width:300,
       wait:true,
       waitConfig: {interval:200},
       icon:'ext-mb-download', //custom class in msg-box.html
       animateTarget: 'mb7'
   });
    setTimeout(function(){
        //This simulates a long-running operation like a database save or XHR call.
        //In real code, this would be in a callback function.
        Ext.MessageBox.hide();
        Ext.example.msg('Done', 'Your fake data was saved!');
    }, 8000);
});

Ext.get('mb8').on('click', function(){
    Ext.MessageBox.alert('Status', 'Changes saved successfully.', showResult);
});

//Add these values dynamically so they aren't hard-coded in the html
Ext.fly('info').dom.value = Ext.MessageBox.INFO;
Ext.fly('question').dom.value = Ext.MessageBox.QUESTION;
Ext.fly('warning').dom.value = Ext.MessageBox.WARNING;
Ext.fly('error').dom.value = Ext.MessageBox.ERROR;

Ext.get('mb9').on('click', function(){
    Ext.MessageBox.show({
       title: 'Icon Support',
       msg: 'Here is a message with an icon!',
       buttons: Ext.MessageBox.OK,
       animateTarget: 'mb9',
       fn: showResult,
       icon: Ext.get('icons').dom.value
   });
});

function showResult(btn){
    Ext.example.msg('Button Click', 'You clicked the {0} button', btn);
};

function showResultText(btn, text){
    Ext.example.msg('Button Click', 'You clicked the {0} button and entered the text "{1}".', btn, text);
};
});
