检查应用浏览器是否打开或关闭

您可以只创建一个简单的包装器来跟踪它是打开的还是关闭的,例如:

var iab_controller = (function(){
    var ref, isOpen = false;

    return {
        open: function(url){
            ref = cordova.InAppBrowser.open(url, '_blank', 'location=yes');
            isOpen = true;
            return ref;
        },
        close: function(){
            if(isOpen){
                ref.close();
                ref = null;
                isOpen = false;
            }
        },
        isOpen: function(){
            return isOpen;
        },
        isClosed: function(){
            return !isOpen;
        }
    };

})();

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

iab_controller.open('http://apache.org');

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

iab_controller.close();

console.log("isOpen: " + iab_controller.isOpen())
console.log("isClosed: " + iab_controller.isClosed())

var browserRef = cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes');
var isOpen = true;

browserRef.addEventListener('exit', function(event) {
  console.log('exit: event fires when the InAppBrowser window is closed.');
  isOpen = false;
});

为InAppBrowser中的退出事件添加侦听器。这将允许您执行逻辑或设置变量来管理状态。
