推荐答案
您可以检查以下代码，可能会对您有所帮助.
You can check below code, it might help you.
<html>
<head>
<script>
var today = new Date();
var expiry = new Date(today.getTime() + 30 * 24 * 3600 * 1000); // plus 30 days
function setCookie(name, value)
{
document.cookie=name + "=" + escape(value) + "; path=/; expires=" + expiry.toGMTString();
}
function putCookie(form)
//this should set the UserName cookie to the proper value;
{
setCookie("userName", form[0].usrname.value);
return true;
}
</script>
</head>
<body>
<form>
<input type="text" value="Enter Your Nickname" id="nameBox" name='usrname'>
<input type="button" value="Go!" id="submit" onclick="putCookie(document.getElementsByTagName('form'));">
</form>
</body>
</html>
虽然定义的函数名称应该是putCookies而不是storeValues和函数调用，但是您可以这样做:putCookie(document.getElementsByTagName('form'));
While defined function name should be putCookies instead of storeValues and function call you can do this way: putCookie(document.getElementsByTagName('form'));
在函数定义中，cookie值可以从以下表格中获取:setCookie("userName"，form [0] .usrname.value);
Inside the function definition cookie values can be get from the form as below: setCookie("userName", form[0].usrname.value);
表单元素应具有属性:name ='usrname'
Form element should have attribute : name='usrname'
它肯定会使用表单元素为您的用户名设置Cookie.
It will surely set cookies for your username with form element.
