Window.get([window_object])

Window.get([window_object])

用途:获取指定window_object窗口(未指定时默认为当前窗口)的窗口对象

• window_object {DOM Window} (可选) DOM窗口对象
• Returns {Window} the native Window object

如果 window_object 是 iframe, 该方法将返回其顶层窗口的 Window 对象.

// 获取当前窗口的`Window`对象
var win = nw.Window.get();

/获取iframe的窗口
var iframeWin = nw.Window.get(iframe.contentWindow);

//返回true
console.log(iframeWin === win);

// 创建窗口并获取它的窗口对象
nw.Window.open('https://github.com/nwjs/nw.js', {}, function(new_win) {
  // do something with the newly created window
});
