好了.可以繼續(xù)了.
接下來(lái)調(diào)用方法.<br />
===========================================================<br />
popHint(Element, Hint, {Type, Event});<br />
===========================================================<br />
Element：彈出對(duì)象。根據(jù)它來(lái)定位的。<br />
Hint：彈出的信息。<br />
Type：彈出類型。其實(shí)說(shuō)類型是不對(duì)的。只是定義個(gè)圖標(biāo)而已...(可自己在樣式里加很多很多"類型")<br />
Event：關(guān)閉觸發(fā)事件。(默認(rèn)click=document.onmousedown,blur=Element.onblur) 一樣可以自己定義很多事件.
