Redirect to a URL and then run a function in the context of that newly loaded page when "DOM Ready"

Question

Is there some way for me do something like the following in Javascript? ( Specifacly I want to do this from Javascript running in an Iphone OS UIWebView)

create a function called RedirectAndExecuteFunctionOnDomReady(url, function)

1. Redirect to the HTML of the provided url
2. When the new HTML DOM is ready, execute the provided function (which will modify the DOM)
3. Finish loading/rendering the Page

Answer 1

No. Read up on the same origin policy (e.g. on Mozilla Developer Center or on Wikipedia).

However, the aside to your question about doing it in a UIWebView could open up some possibilities. I have no iPhone/Webkit/UIWebView experience, but does it support adding event handlers from your app itself? If so, you could add an event handler (not in JS, but in your iPhone app code) that gets triggered by the right domready event and adds the JS (again, from your app code) to the new document.
