代码如下：
<script language="javascript"> function Quickpick() { var ball for( ball = 0; ball < 5; ball++) { this[ball] = parseInt((Math.random() * Math.pow(10,16)) % 49) + 1; for(var list = 0; list < ball; list++) { if(this[list] == this[ball]) { list = ball; ball--; } } } this[ball] = parseInt((Math.random() * Math.pow(10,16)) % 42) + 1; return this; } </script> <script language="javascript"> var idx; var powerball = new Array(6); powerball = this.Quickpick(); document.write("<center>"); document.write("体育彩票选号器"); document.write("<hr width=400><font size=+2>"); for(idx = 0; idx < 5; idx++) document.write(powerball[idx] + " - ") document.write("</font><font color=#D00000 size=+2>" + powerball[idx] + "</font>"); document.write("</center>"); </script>
