Han*_*ach 6 javascript forms cookies
我正在尝试使用用户对Web表单的输入来创建用户名cookie.然而,它不起作用,我不知道为什么.你知道问题是什么吗？
<form>
<input type="text" value="Enter Your Nickname" id="nameBox">
<input type="button" value="Go!" id="submit" onClick="putCookie">
<form>
<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();
}
//this should set the UserName cookie to the proper value;
function storeValues(form){
setCookie("userName", form.submit.value);
return true;
}
</script>
</body>
您可以查看以下代码,它可能会对您有所帮助.
<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,你可以这样做:putCookie(document.getElementsByTagName('form'));
在函数定义中,cookie值可以从下面的表单中获取:setCookie("userName",form [0] .usrname.value);
表单元素应该具有以下属性:name ='usrname'
它肯定会使用表单元素为您的用户名设置cookie.
