在不使用parent.someFunction（）的iframe中调用父函数？

Question

Is this possible?

The function someMethod is a member of the parent window.

iframe content:

<a href="" onclick="Something.call('someMethod', 'Some data'); ">Send some data</a>

Any way to call someMethod without doing...

<a href="" onclick="parent.Something.call('someMethod', 'Some data'); ">Send some data</a>

UPDATE:

Basically I have a presentation layer inside an iframe which has content that calls a metric api function to send a metric to the server. the iframe is in the parent window. The content (presentation) was previously developed without using a parent.SomeAPIMethod() call. How do I intercept the api call from the parent layer? Any way to do this without changing all the metric calls within the content?

Answer 1

You can use into a frame or iframe:

1. window.parent.someFunction(parameters) to call a function in a window up one level.
2. window.top.someFunction(parameters) to call a function the maximum level window. In others words, the container window of all.

For example, this is the JavaScript in the window container:

function someFunction(msg) {
    alert(msg +"!!!");
}

In the frame or iframe you can use with a button:

<button onclick="window.top.someFunction('message');">Trigger function</button>

However, if you want to use a "alias", then you can use this JavaScript:

var aliasFn = window.top.someFunction;

After, when you want to use it:

<button onclick="aliasFn('message');">Trigger function</button>

Hope that helps.
