Dojo是否等同于jQuery.trigger（）？ [英] Does Dojo have an equivalent to jQuery.trigger()?

问题描述

在jQuery中，您可以执行以下操作：

In jQuery, you can do this:

$('#myElement').trigger('change');

如何在Dojo中执行此操作？

How do I do that in Dojo?

推荐答案

我不认为Dojo有类似的功能，至少不如我知道/可以找到的。但是您可以使用以下代码复制此功能：

I don't think Dojo has similar functionality, at least as not as far as I know / can find. But you can use code like the following to replicate this functionality:

dojo.addOnLoad(function() {

    var button = dojo.byId("myButton");
    dojo.connect(button, "onclick", function() { alert("Clicked!"); });

    // IE does things differently
    if (dojo.isIE)
    {
        button.fireEvent("onclick");
    }
    else
    { // Not IE
        var event = document.createEvent("HTMLEvents");
        event.initEvent("click", false, true);
        console.debug(event);
        button.dispatchEvent(event);
    }
});

肯定会更详细一些，但您可以创建自己的Dojo版本的触发器（）与它。

A little more verbose, for sure, but you would be able to create your own Dojo version of trigger() with it.
