Analysis of jquery read/write cookie operation instances,
This document analyzes the jquery read/write cookie operations. We will share this with you for your reference. The details are as follows:
Jquery cookie requires the following script file:
jQuery.cookie = function(name, value, options) {if (typeof value != 'undefined') { options = options || {}; if (value === null) { value = ''; options = $.extend({}, options); 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;}};
You only need to import this file when calling the page.
$. Cookie ("name"); // obtain the cookie value based on the cookie name $. cookie ("name", "value"); // set the cookie name, value $. cookie ("name", value, {expires: 7}); // set attributes such as cookie name, value, and lifecycle $. cookie ("name", null); // remove the cookie Based on the cookie name
