网页上的射击游戏代码，需要先点击“开始”按钮后才能玩游戏，哈哈，界面比较简陋哦，没有使用外部的图片修饰，完全是用网页里固有的元素制作成的，想玩的就先试玩一下吧，可以学习一下JS技术吧。

<HTML><HEAD><TITLE>射击游戏代码</TITLE><META http-equiv=Content-Type content="text/html; charset=gb2312"></HEAD><BODY><SCRIPT language=JavaScript> function MakeArray( n){     this.length = n;     for (var i = 1; i <= n; i++) {         this[i] = 0     }     return this } var d0 = new Date(); var r0 = d0.getSeconds(); function poor_rand(){     d1 = new Date();     r0 = (r0 * r0 + r0 + d1.getSeconds()) % 3721 ;     return r0 % width_n; } var height_n = 8; var width_n =5; var enemy = new MakeArray( width_n); var wtime; var score; var gameover; document.write( "<FORM NAME='fm1'>"); document.write( "<INPUT TYPE='text' NAME='message' SIZE=20>"); document.write( "</FORM>"); document.write( "<FORM NAME='fm2'><TABLE>"); for( var i=0; i<height_n; i++){     document.write( "<TR>");     for( var j=0;j<width_n; j++){         document.write( "<TD><CENTER><INPUT TYPE='radio'></CENTER></TD>");     }     document.write( "</TR>"); } document.write( "<TR>"); for( var j=0;j<width_n; j++){     document.write( "<TD><INPUT TYPE='button' VALUE='射' onClick='fire("         + j + ")'></TD>"); } document.write( "</TR>"); document.write( "</TABLE>"); document.write( "<INPUT TYPE='button' VALUE='开始' onClick='game_start()'>"); document.write( "</FORM>"); function come(){     var n = poor_rand();     document.fm2.elements[ width_n * enemy[n+1] + n].checked = true;     enemy[n+1]++;     if( enemy[n+1] < height_n){         setTimeout("come()", wtime);     }else{       gameover = true;       document.fm1.message.value =  "游戏结束:" + score ;     } } function fire( n){     if( gameover ) return;     for( var i=0; i<enemy[n+1]; i++){         document.fm2.elements[ width_n * i + n].checked = false;     }     score += enemy[ n+1];     document.fm1.message.value = "分数:" + score;     enemy[ n+1] = 0;     if( wtime > 50){ wtime -= 10}; } function game_start(){    for( var n=0; n<width_n; n++){         for( var i=0; i<enemy[n+1]; i++){             document.fm2.elements[ width_n * i + n].checked = false;         }         enemy[n+1] = 0;     }     wtime = 150;     score = 0;     gameover = false;     document.fm1.message.value = "分数:" + score;     setTimeout("come()", wtime); }</SCRIPT></BODY></HTML>
