1.首先，html页面要链接

<script src="https://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>

2.判断是否为微信里浏览器打开？

//使用用微信打开
var checkPlat = {
    isAndroid: function (ua) {
        ua = ua || navigator.userAgent;
        return ua.toLowerCase().indexOf(‘android‘) > -1;
    },

    isIOS: function (platform) {
        if (navigator && navigator.platform) {
            platform = platform || navigator.platform;
            // return /iP(?:hone|od|ad)/.test(platform);
            return /iP(?:hone|od|ad)/.test(navigator.userAgent);
        } else {
            return false;
        }
    },

    isWeixin: function (ua) {
        ua = ua || navigator.userAgent.toLowerCase();
        if (ua.match(/MicroMessenger/i) == "micromessenger") {
            return true;
        } else {
            return false;
        }
    }
}

3.使用以下js:

function shareFn(returnObj, callback) {
    $.ajax({
        url: "/zm_bonus/getConfigInfo",
        type: "post",
        dataType: "json",
        async: false,
        data: {"url": window.location.href},
        success: function (r) {
            wx.config({
                //debug: true,  //开启调试模式
                appId: r.msg.appId, // 必填，公众号的唯一标识
                timestamp: r.msg.timestamp, // 必填，生成签名的时间戳
                nonceStr: r.msg.nonceStr, // 必填，生成签名的随机串
                signature: r.msg.signature,// 必填，签名，见附录1
                // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
                jsApiList: [
                    ‘checkJsApi‘,
                    ‘onMenuShareTimeline‘,
                    ‘onMenuShareAppMessage‘,
                    ‘onMenuShareQQ‘,
                    ‘onMenuShareWeibo‘,
                    ‘getNetworkType‘,
                    ‘previewImage‘,
                    ‘hideOptionMenu‘,
                    ‘showOptionMenu‘
                ]
            });

            wx.ready(function () {
                wx.showOptionMenu();
                var obj = returnObj.call(null, r);
                wx.onMenuShareAppMessage(obj);
                wx.onMenuShareTimeline(obj);
                wx.onMenuShareWeibo(obj);
                wx.onMenuShareQQ(obj);
                wx.showMenuItems({
                    menuList: [
                        "menuItem:share:appMessage",
                        "menuItem:share:timeline",
                        "menuItem:share:qq",
                        "menuItem:share:weiboApp",
                        "menuItem:share:QZone"
                    ]
                });
                callback.call(null);
            });
        },
        error: function () {
            alert("网络错误请重试");
        }
    });
}

shareFn(function (data) {
    // var _link = window.location.host + "/register.html?inviter=" + encodeURIComponent(r.msg.userName || "");
    var _link = window.location.href;
    return {
        title: "让爱传递",//分享的主题
        desc: "帮孩子实现梦想",//分享的内容
        link: _link,//分享后的跳转的页面链接
        imgUrl: "xxxxx/images/com-dev-share.png",//分享后显示的icon
        success: function () {

　　　　　　if (!checkPlat.isWeixin()) {return alert("请在微信客户端打开链接，邀请好友！");} 
　　　　　　else if (!checkPlat.isWeixin()) {return alert("请在微信客户端打开链接，立即分享！")；}
　　　　　　else if(checkPlat.isWeixin()){//成功后的提示alert(分享成功)；}

        },
        cancel: function () {
        },
        fail: function () {
            alert("邀请失败请重试！");
        }
    }
});
