JavaScript常见兼容性问题
Returns the window itself, which is an array-like object, listing the direct sub-frames of the current window.
window.frames[0] is the same thing as document.getElementsByTagName("iframe")[0].contentWindow
2. window.event
在老版本IE或兼容模式中支持,可将方法的第一个参数设为event,如
function click(event) {
var e = event || window.event;
var element = e.target || e.srcElement;
....
}
<input type="button" onclick="click(event)" value="Hello Coco">
event.keyCode -> event.key
3. document.getElementById()
在IE兼容模式中,如根据id找不到元素,将根据name查找。
4. window.showModalDialog
IE和firefox支持window.showModalDialog,chrome 37后不支持,请用window.open代替:
window.open("http://www.w3schools.com", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=500,left=500,width=400,height=400");
