I would like to know how can I load a page in a iframe but with some added things to it (like scripts, header, etc). Suppose I have this example :
which alerts you when you click the right mouse button. And now, suppose I have the following iframe :
alert("You clicked the right mouse button!")
<p>Right button alert. </p>
My question is how to "inject" into the iframe source the script I've talked about, and the declaration :
<iframe src="http://google.com" name="show" height = "400" width = "400">
so that the script can be used. Considering that the pages that will be displayed in the iframe (in the example, google.com) aren't editable, how can I do this thing ?
