子级请求父级窗口元素的OnChange请求

Question

So I have this in my child iframe has this code running with in it. 因此，我的孩子在iframe中拥有此代码，并在其中运行了此代码。

window.parent.document.getElementById("cs_0000").onchange = function () {
    alert('Worked');
};

For what ever reason it's not working. 无论出于什么原因，它都不起作用。

I can run this code: 我可以运行以下代码：

window.parent.document.getElementById("cs_0000").value;

and it will return the value of that element but the on change event doesn't work. 并且它将返回该元素的值，但是on change事件不起作用。

Answer 1

The result was because the hidden fields don't trigger change events. 结果是因为隐藏字段不会触发更改事件。

So after using: 因此，使用后：

.trigger("change");

I was able to catch the event using: 我能够使用以下方法捕获事件：

window.parent.jQuery('#something').on('change', function(){
    // Put stuff here
});
