问题
We want to build a webpage that requests permissions from an iphone user to change their default search provider. Is this possible with through mobile safari?
回答1:
The Window object in Mobile Safari on iOS has what appear to be three undocumented functions that make interaction with the default search engine possible:
window.canSetSearchEngine()
window.getSearchEngine()
window.setSearchEngine(string)
The Yahoo mobile search site uses these functions to throw a (very annoying) dialog box asking "Would you like to change your default search engine to Yahoo? y/n".
I haven't yet been able to make the setSearchEngine() function work because for some reason I don't have permission to do so (i.e., canSetSearchEngine() returns false).
I know the Yahoo code works so it appears that it must be possible to do. I wonder if the js file has to be hosted on a whitelisted domain related to the selected search engine. IOW - perhaps only js code served from a yahoo, google, or bing domain has permission to call the setSearchEngine() function.
Cheers!
