一个简单的html网页，但在浏览器上运行，却没有窗口弹出，实在找不出哪里出了问题了
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script>
function checkRealName()
{
var str = form1.realName.value;
if(str == "")
{
alert("请输入真实姓名");
form1.realName.focus();
return;
}
else
{
var objExp = /[\u4E00-\u9FA5]{2,}/;
if(objExp.test(str) == true)
{
alert("您输入的真实姓名正确");
}
}
else
{
alert("您输入的真实姓名不正确");
}
}
</script>
</head>
<body>
<form name = "form1" method = "post" action = "">
请输入真实姓名：<input name = "realName" type = "text" id = "realName" size = "40">
<br><br>
<input name = "Button" type = "button" class = "btn_grey" onclick = "checkRealName()" value = "检测">
</form>
</body>
</html>
