[转] JavaScript APIs you’ve never heard of (and some you have)
分享自玉伯也叫射雕的微博, 幻灯片在 SlideShare 上, 估计要翻下... 我在 VPS 上放了一个备份, pptx 格式的... 幻灯片里讲了许多很有意思的 API, 比如:
child= list.lastElementChild;
child = child.nextElementSibling;
menu.insertAdjacentHTML("beforebegin",
"<p>Hello world!</p>");
xhr.upload.onprogress = function(event) {
var percentage = event.loaded/event.total * 100;
updateProgress(percentage);
if (element.matchesSelector("body .bar")) {
//do something
}
