BG Color =
要完成此效果需要两个步骤 第一步：把如下代码加入到<head>区域中 <SCRIPT LANGUAGE="JavaScript"> <!-- color=new Array("0","3","6","9","C","F"); speed=250; document.bgColor="FFFFFF"; bg=new Array("FFFFFF","FFFFFF","FFFFFF"); function begin() { document.form.col1.value=" X "; document.form.col2.value=" X "; document.form.col3.value=" X "; i=0; roll(speed); } function roll(speedB) //轮子滚动 { if (document.form.col1.value==" X ") { document.form.c1.value=document.form.b1.value; document.form.b1.value=document.form.a1.value; document.form.a1.value= color[Math.round(Math.random()*10)%6]+ color[Math.round(Math.random()*10)%6]; //利用随机函数产生轮子上的颜色值 } if (document.form.col2.value==" X ") { document.form.c2.value=document.form.b2.value; document.form.b2.value=document.form.a2.value; document.form.a2.value= color[Math.round(Math.random()*10)%6]+ color[Math.round(Math.random()*10)%6]; } if (document.form.col3.value==" X ") { document.form.c3.value=document.form.b3.value; document.form.b3.value=document.form.a3.value; document.form.a3.value= color[Math.round(Math.random()*10)%6]+ color[Math.round(Math.random()*10)%6]; } setTimeout("roll("+speedB+")",speedB); } function stop(col) //轮子停止滚动 { if (col==1) {document.form.col1.value=" ";i++;} if (col==2) {document.form.col2.value=" ";i++;} if (col==3) {document.form.col3.value=" ";i++;} if (i==3) { bg[0]=document.form.a1.value+ document.form.a2.value+ document.form.a3.value; bg[1]=document.form.b1.value+ document.form.b2.value+ document.form.b3.value; bg[2]=document.form.c1.value+ document.form.c2.value+ document.form.c3.value; speedB=500000;roll(speedB); } } function view(letter) //颜色预览 { document.bgColor=bg[letter]; document.form.color.value="#"+bg[letter]; } --> </script> 第二步：把如下代码加入到<body>区域中 <form name="form"> <table cellpadding=2 border=1 align="center"> <tr><td align=center> <input type=text name="a1" size=3 onFocus="this.blur()" value=" "> <input type=text name="a2" size=3 onFocus="this.blur()" value=" "> <input type=text name="a3" size=3 onFocus="this.blur()" value=" "> <input type=button onClick="view(0)" value="预览"><br> <input type=text name="b1" size=3 onFocus="this.blur()" value=" "> <input type=text name="b2" size=3 onFocus="this.blur()" value=" "> <input type=text name="b3" size=3 onFocus="this.blur()" value=" "> <input type=button onClick="view(1)" value="预览"><br> <input type=text name="c1" size=3 onFocus="this.blur()" value=" "> <input type=text name="c2" size=3 onFocus="this.blur()" value=" "> <input type=text name="c3" size=3 onFocus="this.blur()" value=" "> <input type=button onClick="view(2)" value="预览"><br> <input type=button onClick="stop(1)" value=" X " name="col1"> <input type=button onClick="stop(2)" value=" X " name="col2"> <input type=button onClick="stop(3)" value=" X " name="col3"> </td> <td valign=middle align=center> <input type=button onClick="begin()" value="启动!"><p> <table bgcolor=FFFFFF border=1 cellspacing=0> <tr><td align=center valign=middle>按"X" 轮子停止转动...<p> BG Color = <input type=text size=7 value="#FFFFFF" name=color> </td></tr> </table> </td></tr> </table> </form> <p><center> <table class=30pt> <tr><td>颜色的随机产生 </tr><tr><td>按下启动按钮,右边的三排轮子开始滚动 </tr><tr><td>按下三个X按钮颜色值定下来 </tr><tr><td>按下预览按钮可看颜色效果 </tr> </table> <a href="http://www.7stk.com/">欢迎访问网页特效代码</a>
