本文實例講述了JS使用cookie設置樣式的方法。分享給大家供大家參考，具體如下：
var styleShow = ["blackgreen", "purple"];var path = "/";var StyleSwitch = { //設置樣式setStyleSheet: function (StyleName) { var i, a, main; for (i = 0; (a = document.getElementsByTagName("link")[i]); i++) { if (a.getAttribute("rel").indexOf("Style") != -1 && a.getAttribute("title")) { a.disabled = true; if (a.getAttribute("title") == StyleName) { a.disabled = false; this.setCookie("Style", StyleName); } } } }, //獲取當前使用樣式getStyleSheet: function () { var i, a; for (i = 0; (a = document.getElementsByTagName("link")[i]); i++) { if (a.getAttribute("rel").indexOf("Style") != -1 && a.getAttribute("title") && !a.disabled) { return a.getAttribute("title"); } } return null; }, //獲取默認樣式getPreferredStyleSheet: function () { var i, a; for (i = 0; (a = document.getElementsByTagName("link")[i]); i++) { if (a.getAttribute("rel").indexOf("Style") != -1 && a.getAttribute("rel").indexOf("alt") == -1 && a.getAttribute("title") ) { return a.getAttribute("title"); } } return null; }, //獲取cookie getCookie: function (name) { var cookieName = encodeURIComponent(name) + "=", cookieStart = document.cookie.indexOf(cookieName), cookieValue = null; if (cookieStart > -1) { var cookieEnd = document.cookie.indexOf(";", cookieStart); if (cookieStart == -1) { alert(-2); cookieEnd = document.cookie.length; } cookieValue = decodeURIComponent(document.cookie.substring(cookieStart + cookieName.length, cookieEnd)); } for (var i = 0; i < styleShow.length; i++) { if (cookieValue == styleShow[i]) { alert(styleShow[i]); return styleShow[i]; } } return styleShow[0]; }, //生成cookie //name cookie名//value 值//expires 過期時間//path 路徑setCookie: function (name, value, expires, path, domain, secure) { var cookieText = encodeURIComponent(name) + "=" + encodeURIComponent(value) + ";"; if (expires instanceof Date) { cookieText += "expires=" + expires.toGMTString(); } if (path) { cookieText += ";path=" + path; } if (domain) { cookieText += ";domain=" + domain; } if (secure) { cookieText += ";secure"; } document.cookie = cookieText; }, //重置cookie unsetCookie: function (name, path, domain, secure) { this.set(name, "", new Date(0), path, domain, screen); }};更多關於JavaScript相關內容感興趣的讀者可查看本站專題：《JavaScript中json操作技巧總結》、《JavaScript切換特效與技巧總結》、《JavaScript查找算法技巧總結》、《JavaScript動畫特效與技巧匯總》、《JavaScript錯誤與調試技巧總結》、《JavaScript數據結構與算法技巧總結》、《JavaScript遍曆算法與技巧總結》及《JavaScript數學運算用法總結》
