从外部javascript文件中调用位于iframe中的javascript函数

Question

我在iframe中打开了一个html。在那里定义了一个javaScript函数说getSomething（）。现在在父页面中我有一个外部javaScript文件。是否可以从外部javaScript文件访问getSomething（）？

Answer 1

As long as both URLs are from the same domain, you can do it. Try calling something similar to the following from the external script file:

document.getElementByID("ReferringiFrame").getSomething();
