<head> <meta/> <title>i learning js now</title> <script type="text/javascript"> //函数少写大括号了 function haha(){ var mymessage = confirm("Do you like bone?") //'=='中间不能加空格 if (mymessage == ture) { document.write("i know,you are a puppy"); } else { document.write("be a lonely dog,come on"); } } </script> </head> <body> <form> <input type="button" value="haha" onclick="haha()"> </form> </body> </html>你的错误我都写在代码中了.望采纳!

function haha(){ var mymessage=confirm("Do you like bone?") if(mymessage==true){ document.write("i know,you are a puppy"); }else{ document.write("be a lonely dog,come on"); }}规范写法
