jQuery實現帶漸顯效果的人物多級關系圖代碼
編輯：關於JavaScript
本文實例講述了jQuery實現帶漸顯效果的人物多級關系圖。分享給大家供大家參考。具體如下：
這裡演示jQuery實現帶漸顯效果的人物多級關系圖，setQuestPose:function中的n代表共幾個對象 r代表周長 i代表第幾個對象 w代表外面對象的寬帶 h代表外面對象的高度 d代表其實角度，測試時請注意，如果右下角提示有錯誤，請重新刷新頁面即可。
運行效果截圖如下：
具體代碼如下：

看不到效果，刷新一下就可以了；<br>
<div id="box"></div>
</body>

希望本文所述對大家的jQuery程序設計有所幫助。
