小程序之选择拍照或者本地相册

html

css

.img_list {
    width: 100vw;
    display: flex;
    display: -webkit-flex;
    padding: 0 20rpx;
    box-sizing: border-box;
    flex-wrap: wrap;
    -webkit-flex-wrap: wrap;
}

.img_list .img_li,
.addimg {
    width: 200rpx;
    height: 250rpx;
    border: 1px solid #999999;
    margin: 5rpx;
    flex-shrink: 0;
    -webkit-flex-shrink: 0;
}

.addimg image {
    width: 150rpx;
    height: 150rpx;
    margin: 50rpx 25rpx;
}

.img_list .img_li image {
    width: 100%;
    height: 100%;
}

只是一个弹框

 imglist: [
      "https://img.yzcdn.cn/vant/cat.jpeg",
      "https://img.yzcdn.cn/vant/cat.jpeg"
    ]
  img_w_show() {
    // 弹框 是相机拍照还是 从相册中选择的哈
    wx.showActionSheet({
      itemList: ["从手机相册选择", "拍照"],
      success: function(res) {

        
        console.log("选择的是 :", res.tapIndex);

        let sourceType = "camera";
        if (res.tapIndex == 0) {
          sourceType = "camera"; //相机
        } else if (res.tapIndex == 1) {
          sourceType = "album"; //相册
        }

      },
      fail: function(res) {
        console.log(res.errMsg);
      }
    });
  }

选择本地相册图片 或者是 相机拍照

  var _this = this;
    wx.showActionSheet({
      itemList: ["拍照", "从相册中选择"],
      success(res) {
        console.log("选择的是 :", res.tapIndex);
        let sourceType = "camera";
        if (res.tapIndex == 0) {
          sourceType = "camera"; //相机
        } else if (res.tapIndex == 1) {
          sourceType = "album"; //相册
        }

        wx.chooseImage({
          count: 9,
          sizeType: ["original", "compressed"], // 可以指定是原图还是压缩图，默认二者都有
          sourceType: [sourceType],
          success: function(res) {
            var tempFilePaths = res.tempFilePaths;
            console.log(tempFilePaths);//图片路径为 https
            _this.setData({
              imglist: _this.data.imglist.concat(tempFilePaths)
            });
          }
        });
      }
    });

点击加号直接拍照

  img_w_show() {
    var _this = this;
    // 只是单纯的嗲用是拍照 还是相册中选择弹框

    let sourceType = "camera";

    //  从本地相册选择图片或使用相机拍照。
    wx.chooseImage({
      count: 9,
      sizeType: ["original", "compressed"], // 可以指定是原图还是压缩图，默认二者都有
      sourceType: [sourceType],
      success: function(res) {
        var tempFilePaths = res.tempFilePaths;
        console.log(tempFilePaths); //图片路径为 https
        _this.setData({
          imglist: _this.data.imglist.concat(tempFilePaths)
        });
      }
    });
  },
