contentWindow
属性返回当前HTMLIFrameElement的Window对象. 你可以使用这个Window
对象去访问这个iframe的文档和它内部的DOM. 这个是可读属性, 但是它的属性像全局Window
一样是可以操作的.
关于contentWindow的示例
var x = document.getElementsByTagName("iframe")[0].contentWindow;
//x = window.frames[0];
x.document.getElementsByTagName("body")[0].style.backgroundColor = "blue";
// this would turn the 1st iframe in document blue.
