微信开发-缩略图插件

这个主要是实现从手机浏览器打开网页从获取微信好友栏权限到分享的过程，可以分享到微信朋友圈和微信好友列表，是jQuery插件

首先在当前需要分享的页面引入jQuery和一个js（下面会有）文件，点击事件触发从而实现分享功能

当前页面引入部分---------------------------------------------------------------------------------------------------------------------------------------------
<script type="text/javascript" src="assets/app/js/jquery.min.js"></script>
<script type="text/javascript" src="assets/app/js/nativeShare.js"></script>//可以自定义名称

$("#toshare").bind("click", function() {
var config = {
url: "https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx12e89e49926d870f&redirect_uri=http%3a%2f%2fx3ivy8.natappfree.cc%2fwxInfo%2fgetUserInfo%3forderId%3d"+orderid+"&response_type=code&scope=snsapi_userinfo&state=#wechat_redirect", //分享url
title: '生命地图游学|一年一度,梅里雪山勇者徒步之旅,再次集结!', //内容标题
desc: 'hhahah', //描述
img: '', //分享的图片
img_title: '', //图片名称
from: '' //来源
};
var share_obj = new nativeShare('nativeShare', config);
$(".am-share").addClass("am-modal-active");
if ($(".sharebg").length > 0) {
$(".sharebg").addClass("sharebg-active");
} else {
$("body").append('<div class="sharebg"></div>');
$(".sharebg").addClass("sharebg-active");
}
$(".sharebg-active,.share_btn").click(function() {
$(".am-share").removeClass("am-modal-active");
setTimeout(function() {
$(".sharebg-active").removeClass("sharebg-active");
$(".sharebg").remove();
}, 300);
})
});

//在config里的url可以联系后端做一个重定向进行微信公众号配置进而获取微信用户信息，获取的是点击缩略图的用户信息

上面引入的JS文件代码部分-------------------------------------------------------------------------------------------------------------------
