我是HTML新手。我写了下面的代码来从其中一个选项中进行选择。选择其中一个单选按钮并单击提交按钮后,用户应该被重定向到考试页面,其中候选类型来自于在必须在下一页上提取的URL中传递的radiobutton值。
有人可以帮我解决这个问题,传递价值并在下一页提取。
<html>
<head>
<title>Online Examination Portal</title>
<h1>Online Examination</h1>
<script type="text/javascript">
function get_action(form) {
form.action = document.querySelector('input[name = "candidateType"]:checked').value;
}
</script>
</head>
<body>
<div>Select candidate type from below option:<br><br>
<div>
<input type="radio" name="candidateType" value="student">Student
<br>
<input type="radio" name="candidateType" value="professional">Professional
<br><br>
<form action="ExamPage.html" method="get"><input type="submit" value="Submit" onclick="get_action(this);"></form>
<br><br>
<form action="RegistrationPage.html" method=post name="form2"><input type="submit" value="Register"></form>
</div>
</div>
</body>
</html>

您可以使用Cookie或LocalStorage
,LocalStorage
更容易实施,但需要最新的浏览器,用户可能出于隐私原因禁用Cookie。
<强>缓存强>
function setCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function getCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
// First Page
setCookie("myinputvalue", document.getElementsByName("candidateType")[0].value, 10);
// Second Page
getCookie("myinputvalue");
<强> localStorage的强>
if (typeof(Storage) !== "undefined") {
// First Page
localStorage.setItem("myinputvalue", document.getElementsByName("candidateType")[0].value);
// Second Page
localStorage.getItem("myinputvalue");
} else {
// Sorry! No Web Storage support..
// Use the above cookie method.
}
