微信小程序：选择从本地相册选择图片或使用相机拍照

先弹出操作菜单，选择拍照还是从相册选择。根据用户选择进行相应操作。如图所示

代码如下：

browse:function(){let that = this;wx.showActionSheet({itemList: ['从相册中选择', '拍照'],itemColor: "#00ff20",success: function(res) {if (!res.cancel) {if (res.tapIndex == 0) {that.chooseWxImage('album');} else if (res.tapIndex == 1) {that.chooseWxImage('camera');}}}})},/*打开相册、相机 */chooseWxImage: function(type) {let that = this;wx.chooseImage({count: that.data.countIndex,sizeType: ['original', 'compressed'],sourceType: [type],success: function(res) {// 选择图片后的完成确认操作that.setData({aimgurl: res.tempFilePaths});console.log(that.data.aimgurl);}})}
