[英]javascript function save to cookies
For now, i have a function macs, and i need to implement this function to save inside a cookie and have it stored in mysql.. 现在,我有一个功能Mac,我需要实现此功能以保存在cookie中,并将其存储在mysql中。
So how am i supposed to have this function together? 那么我应该如何一起具有此功能?
<script language="JavaScript">
function getMacAddress(){
document.macaddressapplet.setSep( "-" );
return (document.macaddressapplet.getMacAddress());
}
function setCookie(c_name,value,expiredays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+ "=" +escape(value)+ ((expiredays==null) ? "" : ";expires="+exdate.toGMTString());
}
setCookie('cookie_name','getMacAddress()','1');
</script>
<body>
<?php
//Defaults to 1
$javascript_cookie = isset($_COOKIE["cookie_name"]) ? $_COOKIE["cookie_name"] : 1;
echo "$javascript_cookie";
// db insert query
$dbhost = 'localhost';
$dbuser = 'root';
$dbname = 'registration';
mysql_connect($dbhost, $dbuser) or die("Could not connect database");
mysql_select_db($dbname);
$sql_query = mysql_query("SELECT * from user WHERE UserID ='".$_POST['newUserID']."'");
$sql = "INSERT INTO test(mac) VALUES ('".$javascript_cookie."')";
mysql_query($sql);
?>
Here are the two functions I use to handle cookies: 这是我用来处理Cookie的两个函数:
function writeCookie(name,value,days) {
var date, expires;
if (days) {
date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
expires = "; expires="+date.toGMTString();}
else{
expires = "";
}
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
var i, c, ca, nameEQ = name + "=";
ca = document.cookie.split(';');
for(i=0;i < ca.length;i++) {
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 '';
}
Well, for the JavaScript/setCookie part, if you replace 'Text3123234' with getMacAddress(), that should get you started. 好吧,对于JavaScript / setCookie部分,如果用getMacAddress()替换'Text3123234',那应该会让您入门。 So that line should look like: 因此,该行应如下所示:
setCookie('cookie_name', getMacAddress(), 1);
