微信jssdk上传图片，一张一张的上传 和 一次性传好几张

//html模板

<div class="zhaopin_3_2">
            <div id="bbb"></div>
            <img src="/Public/Home/images/jia.png" class="avatar-round1">
        </div>

此方法是一次可多张上传

//js控制

下面使用的方法都是一样的

//封装的方法
//我的是放在  function.php文件里

//下面这两个方法需要用到微信的配置

/**

 * @echo string $jssdk Jssdk_config
 * @author 5heAtMin9 <sheatming@foxmail.com>
 */

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

        debug: '.$debug.',

}




//控制器里需要用到此方法
