ios - 暂停事件在 PhoneGap iPhone 中无法正常工作？

Question

这是我的代码

    //This is an event that fires when a PhoneGap application is put into the background.
    document.addEventListener("pause", onPause, false);

    //This is an event that fires when a PhoneGap application is retrieved from the background.
    document.addEventListener("resume", onResume, false);

    // Handle the pause event
    function onPause(){
    console.log("pause : app is put into background");
    }


    // Handle the resume event
    function onResume() {
    console.log("resume : app is put into foreground");
    }

当我按下主页按钮时，控制台中没有日志，但是当我单击该应用程序(将其置于前台)时，我的日志是

2011-11-22 12:11:37.206 Event[644:207] [INFO] pause : app is put into background
2011-11-22 12:11:37.206 Event[644:207] [INFO] resume : app is put into foreground

不知道为什么前台来的时候会调用pause函数。
我做错了什么吗？

In the pause handler, any calls that go through Objective-C will not work, nor will any calls that are interactive, like alerts. This means that you cannot call console.log (and its variants), or any calls from Plugins or the PhoneGap API. These will only be processed when the app resumes (processed on the next run-loop).
