本文執行個體講述了JS繪製產生花瓣效果的方法。分享給大家供大家參考。具體如下：
這裡使用JS繪製產生花瓣效果，純JS產生的圖形繪製效果，想研究一下JavaScript圖形繪畫方面知識的，不妨參考一下這個小程式，我覺得還是挺不錯的。
運行效果如下圖所示：
具體代碼如下：
<html ><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>Js繪製產生花瓣效果</title></head><body><script Language="javascript">function a(x,y,color){document.write("<img border='0' style='position: absolute; left: "+(x+300)+"; top: "+(y+200)+";background-color: "+color+"' src='px.gif' width=1 height=1>")}</script><script>for(t=1;t<=360;t++){lo=200 * Math.sin(2 * (Math.PI / 180) * t);x = lo * Math.cos((Math.PI / 180) * t);y = lo * Math.sin((Math.PI / 180) * t); a(x,y,"#000000");lo=200 * Math.cos(2 * (Math.PI / 180) * t);x = lo * Math.cos((Math.PI / 180) * t);y = lo * Math.sin((Math.PI / 180) * t); a(x,y,"#ff0000");}</script></body></html>
希望本文所述對大家的javascript程式設計有所協助。
