小程序--图片添加、删除

 首先在data定义一个存放图片的数组

例：img[]

然后在wxml 用wx.for循环出img的数据即可

scImg: function () {

var that = this;

wx.chooseImage({

count: 6,

success: function (res) {

var tempFilePaths = res.tempFilePaths;

var imgList = that.data.img;

for (var iin tempFilePaths){

imgList.push(tempFilePaths[i])

}

that.setData({

img: imgList

})

}

})

},

delImg: function (e) {

var index = e.currentTarget.dataset.index;

var Img = this.data.img;

var that = this;

wx.showModal({

title: '提示',

content: '确定要删除此商品吗？',

success: function (res) {

if (res.confirm) {

console.log('用户点击确定')

Img.splice(index, 1);

} else if (res.cancel) {

return false

console.log('用户点击取消')

}

that.setData({

img: Img

});

}

})

},
