代碼注釋已經盡可能的詳細了,也不多說了.
初步測試暫未發現大的BUG,總體來說不滿意的是鼠標移來移去不斷觸發氣泡時會出現XX為空或不是對象的問題,
雖然不影響效果,但看著IE左下角的黃色警告不爽,暫時不知道如何改進. 加了try/catch解決...
還有就是氣泡默認出現在觸發對象的正上方,當觸發對象在邊上時,氣泡會有一部分出現在窗口外面......也許這種情況可以讓氣泡顯示在左邊或是右邊,感覺可能會有些麻煩,就沒去弄了,比較懶......
越用jquery就越喜歡用它...
bubble.js:
代碼如下:
/*
* @date: 2010-5-30 11:57:22
* @author: 胡靈偉
* Depends:
* jquery.js
*
* function:氣泡提示效果
* use:$("selectors").bubble({fn:getdata, width:width, height:height});
* 對所有需要氣泡提示效果的對象使用bubble方法，
* fn為氣泡中顯示內容獲得方法,即fn中返回的數據會顯示在氣泡中
* 以樣式指代div則有:
* width\height為contents的width\height屬性
* 氣泡總width為left.width + contents.width + right.width
* 氣泡總height為top.height + contents.height + bottom.height
