The example in this article describes the plug-in for jQuery to operate cookie. To share for your reference, the details are as follows:
jQuery.cookie = function(name, value, options) {
if (typeof value != 'undefined') { // name and value given, set cookie
options = options || {};
if (value === null) {
value = '';
options.expires = -1;
}
var expires = '';
if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {
var date;
if (typeof options.expires == 'number') {
date = new Date();
date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));
} else {
date = options.expires;
}
expires = '; expires=' + date.toUTCString();
}
var path = options.path ? '; path=' + (options.path) : '';
var domain = options.domain ? '; domain=' + (options.domain) : '';
var secure = options.secure ? '; secure': '';
document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');
} else {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
};
The call is also convenient:
// How to use it is as follows :
// Set up the cookie The key/value pair
//$.cookie('name', ' value');
// Set up the cookie Keyvalue pairs, expiration dates, paths, fields, security
//$.cookie('name', ' value', {expires: 7, path: ' /', domain: ' jquery.com', secure: true});
// new 1 a cookie Including expiration date The path Domain name etc.
// read cookie The value of the
//var account= $.cookie('name');
// delete 1 a cookie
//example $.cookie('name', null);
I hope this article has been helpful in jQuery programming.
