要完成此效果把如下代码加入到<body>区域中 <Script LANGUAGE="JavaScript"> <-- Hide from non-JavaScript browsers function random(maxValue) { day = new Date(); hour = day.getHours(); min = day.getMinutes(); sec = day.getSeconds(); return (((hour + 1) * (min + 1) * sec) % maxValue) + 1; } function pickSuit() { suit = random(4); if(suit == 1) return "Spades"; if(suit == 2) return "Clubs"; if(suit == 3) return "Diamonds"; return "Hearts"; } function cardName(card) { if(card == 1) return "Ace"; if(card == 11) return "Jack"; if(card == 12) return "Queen"; if(card == 13) return "King"; return "" + card; } function cardValue(card) { if(card == 1) return 11; if(card > 10) return 10; return card; } function PickACard(strWho) { card = random(13); suit = pickSuit(); //alert(strWho + " picked the " + cardName(card) + " of " + suit); return cardValue(card); } function NewHand(form) { form.dealer.value = 0; form.you.value = 0; form.dealer.value = eval(form.dealer.value) + PickACard("Dealer"); form.you.value = eval(form.you.value) + PickACard("You"); } function Dealer(form) { while(form.dealer.value < 17) { form.dealer.value = eval(form.dealer.value) + PickACard("Dealer"); } } function User(form) { form.you.value = eval(form.you.value) + PickACard("You"); if(form.you.value > 21) { alert("不好意思，你爆了!"); } } function LookAtHands(form) { if(form.dealer.value > 21) { alert("庄家爆了，你赢!"); } else if(form.you.value > form.dealer.value) { alert("你赢了!"); } else if(form.dealer.value == form.you.value) { alert("Push!"); } else { alert("庄家赢了!"); } } //--> </Script> <FORM> <TABLE BORDER=3> <TR> <TD>庄家有</TD> <TD><INPUT TYPE=TEXT NAME=dealer>点</TD> </TR> <TR> <TD>你有</TD> <TD><INPUT TYPE=TEXT NAME=you>点</TD> </TR> </TABLE> <INPUT TYPE=BUTTON VALUE="再要一张" onClick=User(this.form)> <INPUT TYPE=BUTTON VALUE="亮牌" onClick="Dealer(this.form);LookAtHands(this.form);"> <INPUT TYPE=BUTTON VALUE="重新发牌" onClick=NewHand(this.form)> 特别说明：如网页特效代码中有引用图片文件等，请自己下载到本地调试！
