angular-json-data v1.0.1

Introduction

This is a directive for easy loading of JSON directly from the HTML. With this directive you can include initial data in the HTML sent to the client instead of lazy-loading the data by doing one or more requests after the page has loaded to a webservice or such.

Usage

Below are some examples of how to use the directive.

First you need to include it in your app:

// Add 'json-data' as a dependency for your app
var app = angular.module("MyApp", ["json-data"]);

Then you can use it like this:

<!-- Use the 'model' attribute to store the data in a property on your controller -->
<json-data model="vm.movies">
    [
        { "title": "Warcraft: The Beginning", year: 2016 },
        { "title": "Star Trek: Beyond", year: 2016 }
    ]
</json-data>

You can use the callback attribute to be notified when the directive have been initialized and the data loaded.

The data variable will be substituted with the loaded data, but you don't have to include it.

<!-- Will call vm.onMovieLoaded() with the JSON object when initialized -->
<json-data callback="vm.onMovieLoaded(data)">
    {
        "title": "Warcraft: The Beginning",
        "year": 2016,
        "imdbScore": 7.5,
        "cast": [
            "Travis Fimmel",
            "Paula Patton",
            "Ben Foster",
            "Dominic Cooper"
        ],
        "director": "Duncan Jones"
    }
</json-data>

You can also combine the two if you want to.

<json-data model="vm.movies" callback="vm.onMoviesLoaded()">
    <!-- ... -->
</json-data>

All valid JSON can be used - objects, arrays and simple types.

<!-- You can store objects, arrays or simple types - all valid JSON can be used -->
<json-data model="vm.count">5</json-data>
<json-data model="vm.userName">"Krusen"</json-data>
<json-data model="vm.isAdmin">true</json-data>

<!-- 'when-all-initialized' attribute will be called when all surrounded json-data directives has been initialied -->
<json-data when-all-initialized="vm.onAllLoaded()">
    <json-data>
        <!-- ... -->
    </json-data>
    <json-data>
        <!-- ... -->
    </json-data>
</json-data>

By default the directive/element will be removed from the DOM after it has been initialized. If you do not want this behavior you can add a keep-element attribute.

<!-- This will stay in the DOM after being initialized -->
<json-data model="vm.data" keep-element>
    <!-- ... -->
</json-data>
