Question

我想创建一个小调查/调查问卷，询问用户他们是否年龄超过18岁。一旦按下Enter按钮，我想做两个选项。一：如果他们不超过18岁，它将把他们带到另一个网页。还有两个：如果他们超过18岁，它会将他们带到另一个网页。它让我想起了Java中的“if”“else”语句，但我知道这不是Java。我正在使用HTML（Dreamweaver），我无法弄明白。有人能指出我正确的方向吗？

我已经袒露了它：

<p></p>
<form name="input" action="#" method="get">
<input type="submit" value="Enter">

</html>

这是一个示例脚本，用于重定向用户，使用javascript检查在广播中选择的内容：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>WAIT!</title>
</head>
<script>
function redirect() {
    if(document.getElementById("m").checked == true)
    {
        window.open("http://www.codeforbrowser.com")
    }
    else {
        window.open("http://www.yahoo.com")

给你的表格一些id;

<form id="sex_form">
<input type="radio" name="sex" value="male">
younger than 18<br>
<input type="radio" name="sex" value="female">
18+
</form> 
<input type="submit" onclick="validate()" value="Enter">

    <script type="text/javascript">
        function validate(){
            var form = document.getElementById('sex_form');
            if(form.firstElementChild.checked){
            alert('to younger');
                            //window.open('younger');
            }
            else if(form.firstElementChild.nextElementSibling.nextElementSibling.checked){
                            //window.open('older');
            alert('to 18+');
           }
            else
            alert('none selected');
        }
