Ezdz is a jQuery plugin to turn any standard input type file into a nice drag & drop zone with validators and previews.

Ezdz uses HTML5 File, Drag and Drop API, so it works properly on modern browsers only. I've tested it on last version of Chrome, Firefox and Safari on MacOSX and IOS7 safari mobile only. Feedbacks are welcomed.

Ezdz is in an early stage of development. Some demos are coming... Meanwhile please check a quick demo on Codepen. Here is a screenshot — Hey! Don't drag/drop files below, it's just a screenshot!

Include jQuery.

<script src="jquery.min.js"></script>

Include Ezdz styles.

<link rel="stylesheet" href="ezdz/dist/jquery.ezdz.min.css">

Include Ezdz script.

<script src="ezdz/dist/jquery.ezdz.min.js"></script>

And apply Ezdz to your inputs type file.

$('input[type="file"]').ezdz();

Add a custom class to the container. By default none.

Set the dropzone text. By default "drop a file".

Set if a image preview is displayed when an image is dropped. By default "true".

Set a link to a previously uploaded file. By default none. This value can also be set in the element.

<input type="file" name="file" data-value="img/previously-uploaded-logo.png" />

Ezdz classes. By default they are:

{ classes: {
        main:   'ezdz-dropzone',
        enter:  'ezdz-enter',
        reject: 'ezdz-reject',
        accept: 'ezdz-accept',
        focus:  'ezdz-focus'
    }
}

Ezdz allowed validators. By default they are:

{ validators: {
        maxSize:   null,
        width:     null,
        maxWidth:  null,
        minWidth:  null,
        height:    null,
        maxHeight: null,
        minHeight: null
    }
}

Self-explanatory I guess.

$('[type="file"]').ezdz({
    validators: {
        maxWidth: 600,
        maxHeight: 400,
        maxSize: 1000000
    }
});

Allowed mime-types are defined in the input tag with a standard acceptattribute.

<input type="file" name="logo" accept="image/png, image/jpeg" />

Called when the dropzone is built.

Called when the dropzone is entered by the mouse.

Called when the dropzone is leaved by the mouse.

Called when a dropped/added file is added and accepted by validators.

{   accept: function(file) {
        alert('The file "' + file.name + '" is ok.');
    }
}

Called when a dropped/added file is rejected by validators.

{   reject: function(file, errors) {
        if (errors.maxWidth || errors.maxHeight) {
            alert('The file "' + file.name + '" is too big.');
        }
    }
}

Called before displaying the filename in the preview.

{   format: function(filename) {
        return filename.uppercase();
    }
}

Settings can be set for all instances.

$.ezdz.default = {
    validators: {
        maxWidth: 600,
        maxHeight: 400,
        maxSize: 1000000
    }
}

Inject a preview in the dropzone.

$('[type="file"]').ezdz('preview', 'img/previously-uploaded-logo.png');

Set to null the preview is removed.

$('[type="file"]').ezdz('preview', null);

Get or set the settings.

As a getter:

var options = $('[type="file"]').ezdz('options');

As a setter:

$('[type="file"]').ezdz('options', {
    validators: {
        maxSize: 10000
    }
});

Remove Ezdz from the input and get back to normal.

$('[type="file"]').ezdz('destroy');

Check if the browser is compatible with HTML5 api needed by Ezdz.

if ($.ezdz.isBrowserCompatible() === false) {
    console.log('No ezdz for this browser. Standard input file only.');
}
