<HTML><HEAD> <Script Language="JavaScript"> function check() { var inst = "爱好："; if(document.myform.txt1.value=="") { alert("请输入姓名！"); } else { alert("姓名："+document.myform.txt1.value ); if(document.myform.sex[0].checked) alert("性别：男"); else alert("性别：女"); if(document.myform.inst[0].checked) inst += "游泳"; if(document.myform.inst[1].checked) inst += ",滑冰"; if(document.myform.inst[2].checked) inst += ",散步"; if(inst=="爱好：") alert("赶快培养一个爱好吧！"); else alert(inst); } } </Script></HEAD><BODY> <center> <form name="myform"> <p>请输入您的姓名： <input type="text" name="txt1" value=""> <p>请选择您的性别： <p>男<input type="radio" value="男" name="sex" checked> <p>女<input type="radio" value="女" name="sex"> <p>请选择您的爱好： <p>游泳<input type="checkbox" value="游泳" name="inst" checked> <p>滑冰<input type="checkbox" value="滑冰" name="inst"> <p>散步<input type="checkbox" value="散步" name="inst"> <p><input type="button" value="Click" OnClick="check()"> </form> </center></BODY></HTML>Solved, through BCompare software to compare the differences with the source code, it was found that if(document.myform.sex[0].checked) alert("Gender: Male"); inside the left bracket It’s Chinese parentheses, I’ll have to be more careful in the future.
