If jquery.cloudinary is loaded as an AMD withal, you need to initialize the Cloudinary fileupload fields e.g., past calling $("input.cloudinary-fileupload[type=file]").cloudinary_fileupload();

The following web log post details the process of setting upwardly a jQuery based file upload. http://cloudinary.com/web log/direct_image_uploads_from_the_browser_to_the_cloud_with_jquery
The Cloudinary Documentation can be institute at: http://cloudinary.com/documentation
Cloudinary JavaScript library
The Cloudinary JavaScript library API reference can be found at: https://cloudinary.github.io/pkg-cloudinary-jquery-file-upload
The Cloudinary JavaScript library provides several classes, defined under the "cloudinary" domain.
Configuration
Start by instantiating a new Cloudinary course:
Equally jQuery plugin
An example of the Cloudinary jQuery main class, CloudinaryJQuery, is instantiated every bit $.cloudinary.
$ . cloudinary . config ( { cloud_name: "demo" } ) ; Explicitly
var cl = cloudinary . CloudinaryJQuery . new ( { cloud_name: "demo" } ) ; Using the config function
// Using the config role var cl = cloudinary . CloudinaryJQuery . new ( ) ; cl . config ( "cloud_name" , "demo" ) ; From meta tags in the electric current HTML document
When using the library in a browser environment, you can use meta tags to define the configuration options.
The init() function is a convenience function that invokes both fromDocument() and fromEnvironment().
For case, add the following to the header tag:
< meta name="cloudinary_cloud_name" content="demo"> In your JavaScript source, invoke fromDocument():
var cl = cloudinary . Cloudinary . new ( ) ; cl . fromDocument ( ) ; // or cl . init ( ) ; From environment variables
When using the library in a backend environs such every bit NodeJS, you can utilise an surround variable to ascertain the configuration options.
Prepare the environment variable, for case:
export CLOUDINARY_URL=cloudinary://demo In your JavaScript source, invoke fromEnvironment():
var cl = cloudinary . Cloudinary . new ( ) ; cl . fromEnvironment ( ) ; // or cl . init ( ) ; URL generation
cl . url ( "sample" ) // "http://res.cloudinary.com/demo/image/upload/sample" cl . url ( "sample" , { width: 100 , crop: "fit" } ) // "http://res.cloudinary.com/demo/image/upload/c_fit,w_100/sample" HTML tag generation
You lot can generate HTML tags in several ways:
Cloudinary::image() generates a DOM tag, and prepares it for responsive functionality. This is the same functionality as $.cloudinary.prototype(). (When using the jQuery plugin, the src-cache data attribute is stored using jQuery'south information() method and so is not visible.)
produces:
< img src="http://res.cloudinary.com/demo/prototype/upload/sample"> You tin can generate an image Tag using the imageTag function:
var tag = cl . imageTag ( "sample" ) ; tag . toHtml ( ) ; which produces:
< img src="http://res.cloudinary.com/demo/epitome/upload/sample"> and:
tag . transformation ( ) . crop ( "fit" ) . width ( 100 ) . toHtml ( ) ; which produces:
< img src="http://res.cloudinary.com/demo/paradigm/upload/c_fit,w_100/sample"> You can likewise use ImageTag independently:
var tag = cloudinary . ImageTag . new ( "sample" , { cloud_name: "some_other_cloud" } ) ; tag . toHtml ( ) ; which produces:
< img src="http://res.cloudinary.com/some_other_cloud/image/upload/sample"> Transformation
In addition to using a apparently object to define transformations or using the builder methods (both described above), yous can ascertain transformations past using the Transformation course:
var tr = cloudinary . Transformation . new ( ) ; tr . crop ( "fit" ) . width ( 100 ) ; tr . serialize ( ) // "c_fit,w_100" You lot tin also chain transformations together:
var tr = cloudinary . Transformation . new ( ) ; tr . width ( 10 ) . crop ( 'fit' ) . concatenation ( ) . angle ( 15 ) . serialize ( ) // "c_fit,w_10/a_15" jQuery plugin
This Cloudinary jQuery plugin is fully astern compatible with the previous cloudinary_js version. When loaded, the new JavaScript library instantiates a CloudinaryJQuery object and attaches it to jQuery.
The post-obit listing includes a sample of the API provided by this library:
-
$.cloudinary.config(parameter_name, parameter_value)- Sets parameter_name's value to parameter_value. -
$.cloudinary.url(public_id, options)- Returns a cloudinary URL based on your configuration and the given options. -
$.cloudinary.image(public_id, options)- Returns an HTML image tag for the photo specified by public_id -
$.cloudinary.facebook_profile_image,$.cloudinary.twitter_profile_image,$.cloudinary.twitter_name_profile_image,$.cloudinary.gravatar_image,$.cloudinary.fetch_image- Same equallyprototypejust returns a specific type of image. -
$(jquery_selector).cloudinary(options)- Goes over the elements specified by the jQuery selector and changes all the images to be fetched using Cloudinary's CDN. Using options, you can likewise specify transformations to the images. Theoptionsparameters are similar across all cloudinary frameworks. Please refer to jQuery image manipulation for a more than consummate reference regarding the options.
