用js实现的十进制的颜色值转换成十六进制的代码_javascript技巧

<script type="text/javascript"> function MyColor(name,r,g,b){ this.name=name; this.red=r; this.green=g; this.blue=b; } MyColor.prototype.hexValue=function(){ var hR=this.red.toString(16); var hG=this.green.toString(16); var hB=this.blue.toString(16); return "#"+(this.red<16?("0"+hR):hR)+(this.green<16?("0"+hG):hG)+(this.blue<16?("0"+hB):hB); }; var CnLeiColor=new MyColor("red",255,0,0); alert(CnLeiColor.hexValue()); </script>
