height: auto;

}

},

imageLoad: function (e) {//获取图片真实宽度

var imgwidth = e.detail.width,

imgheight = e.detail.height,

//宽高比

ratio = imgwidth / imgheight;

console.log(imgwidth, imgheight)

//计算的高度值

var viewHeight = 750 / ratio;

var imgheight = viewHeight;

var imgheights = this.data.imgheights;

//把每一张图片的对应的高度记录到数组里

})

},
