easyui换主题，并记录在cookie

easyui换皮肤本身实现了，可是下次打开浏览器的时候，上次选中的皮肤又变回默认皮肤了，怎样让浏览器记住本身所选的皮肤。这里我给出个人解决方案。

注：引入JS的顺序jquery>cookie>easyuicss>changeEasyUITheme.js

首先将easyui的样式文件加入一个ID，这里命名为easyuiTheme，而后在样式文件下面加入一个JS文件

<script type="text/javascript" charset="UTF-8" src="jslib/jquery-easyui-1.2.5/jquery-1.7.1.min.js"></script>

<script type="text/javascript" charset="UTF-8" src="jslib/jquery.cookie.js"></script>

<link id="easyuiTheme" rel="stylesheet" type="text/css" href="jslib/jquery-easyui-1.2.5/themes/gray/easyui.css">
<script type="text/javascript" charset="UTF-8" src="jslib/changeEasyuiTheme.js"></script>
<link rel="stylesheet" type="text/css" href="jslib/jquery-easyui-1.2.5/themes/icon.css">
<script type="text/javascript" charset="UTF-8" src="jslib/jquery-easyui-1.2.5/jquery.easyui.min.js"></script>
<script type="text/javascript" charset="UTF-8" src="jslib/jquery-easyui-1.2.5/locale/easyui-lang-zh_CN.js"></script>

changeEasyuiTheme.js文件的内容是

function changeThemeFun(themeName) {/* 更换主题 */

var $easyuiTheme = $('#easyuiTheme');

var url = $easyuiTheme.attr('href');

var href = url.substring(0, url.indexOf('themes')) + 'themes/' + themeName + '/easyui.css';

$easyuiTheme.attr('href', href);

var $iframe = $('iframe');

if ($iframe.length > 0) {

for ( var i = 0; i < $iframe.length; i++) {

var ifr = $iframe[i];

$(ifr).contents().find('#easyuiTheme').attr('href', href);

}

}

$.cookie('easyuiThemeName', themeName, {

expires : 7

});

};

if ($.cookie('easyuiThemeName')) {

changeThemeFun($.cookie('easyuiThemeName'));

}

jquery.cookie.js的内容是

jQuery.cookie = function (key, value, options) {

    // key and value given, set cookie...

    if (arguments.length > 1 && (value === null || typeof value !== "object")) {

        options = jQuery.extend({}, options);

        if (value === null) {

            options.expires = -1;

        }

        if (typeof options.expires === 'number') {

            var days = options.expires, t = options.expires = new Date();

            t.setDate(t.getDate() + days);

        }

        return (document.cookie = [

            encodeURIComponent(key), '=',

            options.raw ? String(value) : encodeURIComponent(String(value)),

            options.expires ? '; expires=' + options.expires.toUTCString() : '', // use expires attribute, max-age is not supported by IE

            options.path ? '; path=' + options.path : '',

            options.domain ? '; domain=' + options.domain : '',

            options.secure ? '; secure' : ''

        ].join(''));

    }

    // key and possibly options given, get cookie...

    options = value || {};

    var result, decode = options.raw ? function (s) { return s; } : decodeURIComponent;

    return (result = new RegExp('(?:^|; )' + encodeURIComponent(key) + '=([^;]*)').exec(document.cookie)) ? decode(result[1]) : null;

};

使用的时候

changeThemeFun('default');

changeThemeFun('gray');
