Retrive image Data URL from Image Component

[bahar.wadia]

In my App, I am taking pictures (using the camera) that I save to the Image Component (Data URL - format).

Next, I want to be able to retrieve the Data URL from the Image Component.

How do I do that?

Hello,

Not sure I understand correctly, do you save them to Database?
Here is how to retrieve objects from DB http://docs.appery.io/documentation/b...

When I capture a picture with a camera I directly save it to the Image Component. Now I want to get the Data URL that is stored in the Asset property of the Image Component, using JavaScript.

How do I do that?

Any updates?

Hi Bahar,

This code returns the image URL by its name, so you can use it:
preAppery.getImagePath("imagename");/pre
You can also try codeAppery('imagename').attr('src')/code to get the image URL.
If you upload image through image Assets you can use relative path: prebackground: url("../image/imagename.jpg");/pre
Here 'imagename' is a name of the image.

How do I get the 'Asset' property of an image component and store in local storage. I know how to do this using Events, but I want to do this with Javascript.

Thanks for your help.

Hello,

The image component doesn't have "Asset" attribute, but has "src".
You can store this value in local storage with Javascript: localStorage.setItem('src', Appery('imagename').attr('src'));

Hi,
In my app, the user can take pictures (using the camera) and save them in Cloudinary. (Cloudinary is an end-to-end image management solution for mobile apps).

With some help of Cloudinary support, I ́ve manage to upload the images.

The URL to one image taken with camera is like this

http://res.cloudinary.com//image/uplo...

I want to retrive the images previously uploaded by users, in another page...

This is what I did:

I created a REST service (but couldnt make it work)

1. In settings I add in the URL field:
   http://res.cloudinary.com//image/uplo...

2. method: get

3. Data type xml

   After that In the image field of the Test tab I put: ji5elmpuh3cpgbrgovcx.jpg

   The Test is successful, but cant created the service response..

   What Im doing wrong?
   How can I retrive those images?

   Regards

Hello Alex,

Sorry, could you please clarify, your link (http://res.cloudinary.com//image/uplo...) does not open, so I don't really understand is this the direct link to the picture or not?
