本文實例分析了jquery讀寫cookie操作。分享給大家供大家參考,具體如下:
jquery cookie需要腳本文件如下:
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;}};
頁面調用只要引進這個文件
$.cookie("name"); //根據(jù)cookie名字取到cookie值$.cookie("name", "value");//設置cookie 名字,值$.cookie("name", value, { expires: 7 }); //設置cookie 名字,值,生命周期等屬性$.cookie("name", null); //根據(jù)cookie名移除cookie
希望本文所述對大家jQuery程序設計有所幫助。
