JS配置代码

<script type="text/javascript" src='http://res.wx.qq.com/open/js/jweixin-1.0.0.js'></script>
 <script type="text/javascript">
 wx.config({
 debug: false,
 appId: '{$signPackage["appId"]}',
 timestamp: '{$signPackage["timestamp"]}',
 nonceStr: '{$signPackage["nonceStr"]}',
 signature: '{$signPackage["signature"]}',
 jsApiList: [
  // 所有要调用的 API 都要加到这个列表中
  'checkJsApi',
  'onMenuShareTimeline',
  'onMenuShareAppMessage',
  'onMenuShareQQ',
  'onMenuShareWeibo',
  'onMenuShareQZone'
 ]
 });
 </script>
 <script type="text/javascript" src='http://203.195.235.76/jssdk/js/zepto.min.js'></script>

JS分享代码：

<script type="text/javascript">
  //完成wx.config，执行这里
   wx.ready(function () {
    //分享到朋友圈
    wx.onMenuShareTimeline({
     title: '1111111', // 分享标题
     link:window.location.href,
     imgUrl: "{pigcms:$res['pic']}", // 分享图标
     success: function () {
		 // 分享成功执行此回调函数
     alert('success');
     },
     cancel: function () {
     alert('cancel');
     }
    });

    //分享给朋友
    wx.onMenuShareAppMessage({
     title: '22222', // 分享标题
     desc: '22222',
     link:window.location.href,
     imgUrl: "{pigcms:$res['pic']}", // 分享图标
     trigger: function (res) {
      // 不要尝试在trigger中使用ajax异步请求修改本次分享的内容，因为客户端分享操作是一个同步操作，这时候使用ajax的回包会还没有返回
     },
     success: function (res) {
		  // 分享成功执行此回调函数
      alert('已分享');
     },
     cancel: function (res) {
      alert('已取消');
     },
     fail: function (res) {
      alert(JSON.stringify(res));
     }
    });
   });
