将网站分享到第三方，如下：
1.引入jquery
2.js插件，代码如下：
(function (global, doc, factoryFn) {var factory = factoryFn(global, doc);if (!(typeof (ChePC) === 'object')) {ChePC = {};}ChePC.sharePage = ChePC.sharePage || factory;window.define && define(function (require, exports, module) {return factory;});})(this, document, function (window, document) {var sharePage = function (options) {var that = this,defaultOpts = {config: {shareUrl: window.location.href,shareTitle: document.title ?

3.用法：
这种调用方式 分享的title自动获取的是页面tittle 描述是页面的description，分享地址是当前页面url 分享的图片是当前页面第一张图
var shareFun=new ChePC.sharePage();
如需定制这些分享信息
需用以下方式调用
var shareFun=new ChePC.sharePage({config:{shareUrl:"url地址", //选填 分享地址 默认为当前页面地址shareTitle:"分享标题",//选填 分享标题 默认为当前页面titleshareDescription:"分享描述",shareImg:"分享图片地址" //选填 分享图片 默认为当前页面第一张图片}});
4.效果如下：
