And interceptors have this function.: Visitors click on the Library button--and the background blocker intercepts the method--to determine i

I have been using window.open (URL) to open a new switch card loading page, and I found this situation when I used the Opera browser test today.The first thought was window.open () browser compatibility issues, so try a-tag click, Form form submission, and window.open () to add "_blank" parameter of the way not.Later, it might be a question of the AJAX request callback. Finally, Baidu told me a solution, as follows.Workaround:1, asynchronous to synchronous, that is: Async:false2. Point the new w

What is broadcastreceiver for? is an implementation of the observer pattern mechanism Broadcastreceiver is usually out of wait until the event it subscribes to is triggered As with Activity,contentprovider, you need to inherit broadcastreceiver and register in manifest How do I subscribe to events? How does the event issue a broadcast? What kind of broadcast do you use to express? Broadcast is divided into ordinary broadcast and orderly broadcast The system receives
