在wx.showActionSheet内使用wx.chooseImage时, 异常
我想实现的需求: 点击按钮弹出actionsheet, 点击其中一项, 执行wx.chooseImage, 在相册中选择照片;
实际表现: 点击按钮弹出actionsheet, 点击其中一项, wx.chooseImage没有执行, 而是又__重新弹出了一遍actionsheet__, 再次点击其中一项, wx.chooseImage可正常执行;
代码:
chooseImageActionNow: function (e){
var that = this;
wx.showActionSheet({
itemList: [‘拍照’, ‘从手机相册选择’],
success(res){
if (res.tapIndex == 0){
}
else if (res.tapIndex == 1){
that.chooseImageFromPhotoAlbum();
}
},
})
}
chooseImageFromPhotoAlbum()
{
var that = this;
wx.chooseImage({
count: 3 - that.data.uploaderNum, // 默认9
sizeType: [‘original’, ‘compressed’], // 可以指定是原图还是压缩图，默认二者都有
sourceType: [‘album’, ‘camera’], // 可以指定来源是相册还是相机，默认二者都有
success: function (res)
{
let tempFilePaths = res.tempFilePaths;
let uploaderList = that.data.uploaderList.concat(tempFilePaths);
}
that.setData({
uploaderList: uploaderList,
uploaderNum: uploaderList.length,
})
},
})
},
