推荐答案

鉴于：

var myWindow = open("foo.bar");

旧方法：更改窗口对象的名称 property：

Old method: Change the window object's name property:

myWindow.name = "...";
// in foo.bar:
setInterval(someFunctionToCheckForChangesInName, 100);

HTML5方法：调用window对象的 postMessage 方法：

HTML5 method: Call the window object's postMessage method:

myWindow.postMessage("...", "*");
// in foo.bar:
(window.addEventListener || window.attachEvent)(
  (window.attachEvent && "on" || "") + "message", function (evt) {
    var data = evt.data; // this is the data sent to the window
    // do stuff with data
  },
false);
