There 开发者_JAVA技巧is a certain page (say, named "TargetPage.html" in which I inject the Javascript code below by means of a Firefox extension:
<!-- TargetPage.html -->
unsafeWindow.document.getElementById("target-element").click();
I want to embed this page into another page (say, named "AnotherPage.php") by using the HTML tag "iframe". Like below:
<!-- AnotherPage.php -->
<iframe src="TargetPage.html"></iframe>
Now that I embedded it via "iframe", there is no way to inject any JavaScript code with a browser extension.
Is there any way of running this code in the embedded page?
Only if both pages are in the same domain.
Otherwise is considered cross-domain scripts, and it's a big no-no, for browsers to allow it.
However, there are ways to achieve such communication between domains.
