分享功能可以利用插件share.js插件，也可以自己定义。只要知道各平台的分享地址及相应的参数赋值就可以了。
//第一种方法
//引入插件
<script src="../libs/jquery/jquery/dist/jquery.share.min.js"></script>
//分享功能
$scope.sharePoster = function(platform){
//获取需要分享的图片地址
var posterUrl=angular.element("#myPoster").attr("src");
if(!posterUrl){
var layer=document.createElement("div");
layer.id="layer";
layer.innerHTML="请先上传图片再分享哦！"
var style=
{
background:"#000000",
color:"#ffffff",
position:"absolute",
zIndex:10,
width:"484px",
height:"62px",
lineHeight:"61px",
textAlign:"center",
fontSize:"18px",
borderRadius:"10px",
opacity: 0.75,
left:"38%",
top:"45%"
}
for(var i in style)
layer.style[i]=style[i];
if(document.getElementById("layer")==null)
{
document.body.appendChild(layer);
setTimeout("document.body.removeChild(layer)",2000)
}
return
}
var link = '填入当前页面路径';
var image = posterUrl;
var title = '好好学习天天向上';
$('#shareposter').share({
url: link,
title: shareTitle,
description: shareTitle,
image: image,
sites: ['weibo','qq','qzone','douban']
});
var shareLink = $('#shareposter').find('.icon-'+platform).attr('href');
window.open(shareLink,'_blank');
}
