如何在按钮的处理程序中添加if / else条件。因此,如果条件为真,我将按钮指向某个函数(提交),否则指向另一个函数(submit1)。
var btn_submitform = Ext.create('Ext.Button', {
width:75,
height:30,
text:'Submit',
id:"btn_submitform",
handler: submit
});

只需在处理程序中检查该条件:
onSubmit: function(button, event, eOpts) {
if(true) {
this.function1();
//
this.fireEvent('event1', [button, event, eOpts]);
}
else {
this.function2();
//
this.fireEvent('event2', [button, event, eOpts]);
}
或基于该条件绑定处理程序(例如在控制器中):
var button = Ext.ComponentQuery.query('button[id=btn_submitform]')[0];
if(true) {
button.on('click', 'function1');
}
else {
button.on('click', 'function2');
}
或创建委托:
var form = Ext.ComponentQuery.query('form')[0];
form.addListener({
// Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
delegate: 'button',
click: function(button, event, eOpts) {
if (button.id === 'btn_submitform') {
alert('Submit button tapped!');
}
else {
alert('Other button tapped!');
}
}
});
