帮忙补一下预览图片接口的JS代码
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="http://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>
<script src="jquery-3.2.1.min.js"></script>
<script>
wx.previewImage({
current: ,
urls:
});
</script>
</head>
<body>
<img src="" />
<img src="" />
</body>
</html>
config注入成功了。研究previewImage了半天没成功，麻烦给个示例。
