ExtJS 4.1。
在Ext.button类上有类似Ext.button.click();方法吗？
是否可以通过一种方法以编程方式“点击”按钮？
答案 0 :(得分：24)
或者如果你有MVC结构，你可以触发按钮的click事件，如果你正在控制器中监听事件并且有一个相关的功能，它将被调用。
button.fireEvent('click', button);

此论坛上的最后一个答案可能会让您更深入地了解如何做到这一点 他们在这里 -
1)Create the event code in a function and call the function from both sides: btn.on("clic", ...) and from the code you want to simulate the click.
2)Use: btnView.btnEl.dom.click();

ExtJS 4.2.1
Ext.get('component-id-of-extjs-button').el.dom.click();
Ext.get('toggle-button2').el.dom.click();
适合我。

如果按钮使用处理程序，您可以直接调用按钮的功能。
考虑button是一个Ext JS组件，您可以使用：
button.handler(button);
或者如果您想要达到事件的功能，请点击＆＃39;：
button.listeners.click(button);
这也可以调用不同的按钮事件。

由于我需要很多按钮，因此更容易在按钮类上实现覆盖，这会增加一个点击功能：
Ext.define('Ext.override.Button',{
override:'Ext.button.Button',
click:function() {
this.getEl().dom.click();
}
})
将此覆盖添加到代码库后，以下内容就像魅力一样：
Ext.getCmp("MyButton").click()
与fireEvent或fireHandler不同，它适用于所有类型的按钮 - 无论它们是否具有单击事件或处理程序，还是它们都是切换按钮，其中单击的按钮也必须被标记为按下。
答案 5 :(得分：1)
如果你需要执行按钮的“处理程序”，只需运行它（使用ExtJS 4.2测试）
button.fireHandler()

如果您想在测试脚本中执行此操作，请查看我的Ext.ux.Test library。如果您需要其他东西，我建议您重新考虑您的方法。
答案 7 :(得分：0)
其他答案都没有对我有用，但我觉得我觉得有些简单：
var button=Ext.get('the_id_div');
button.dom.click();
