微信小程序 长按事件 删除图片

1：页面代码

<view class="uploader__files">

<block wx:for="{{images}}" wx:key="{{item.id}}" >

<view class="uploader__file" bindlongpress="deleteImage" data-index="{{index}}">

<image mode="aspectFill" class="uploader__img" src="{{item}}" />

</view>

</block>

</view>

 

2：js代码 

deleteImage: function (e) {
    var that = this;
    var images = that.data.images;
    var index = e.currentTarget.dataset.index;//获取当前长按图片下标
    wx.showModal({
      title: '提示',
      content: '确定要删除此图片吗？',
      success: function (res) {
        if (res.confirm) {
          console.log('点击确定了');
          images.splice(index, 1);
        } else if (res.cancel) {
          console.log('点击取消了');
          return false;
        }
        that.setData({
          images
        });
      }
    })
  }

要点：

1：长按事件是用bindlongpress(不会跟点击事件bindtap冲突);
