Retrieving IFrame content using javascript

[borispio]

I have already received javascript code from this very website.\[code\]alert(window.frames['sc_frame'].document.getElementsByTagName('body')[0].innerHTML);\[/code\]or\[code\]alert(window.frames['sc_frame'].document.getElementsByTagName('body')[0].innerText);\[/code\]The problem is I am having this error.\[code\]Unsafe JavaScript attempt to access frame with URL http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxx from frame with URL http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Domains, protocols and ports must match.(anonymous function)InjectedScript._evaluateOnInjectedScript._evaluateAndWrapInjectedScript.evaluateTypeError: Cannot call method 'getElementsByTagName' of undefinedarguments: Array[2]get message: function () { [native code] }get stack: function () { [native code] }set message: function () { [native code] }set stack: function () { [native code] }type: "non_object_property_call"__proto__: Error\[/code\]I also understand the cause as my \[code\]IFrame\[/code\] is calling to another domain.\[code\]<iframe id="sc_frame" src="http://example1.com"></iframe>\[/code\]I use the above code from \[code\]http://example.com\[/code\].
