<h1>Advanced JSON Editor Example</h1>
<p>This example demonstrates the following:</p>
<ul>
<li>Loading external schemas via ajax (using $ref)</li>
<li>Setting the editor's value from javascript (try the Restore to Default button)</li>
<li>Validating the editor's contents (try setting name to an empty string)</li>
<li>Macro templates (try changing the city or state fields and watch the citystate field update automatically)</li>
<li>Enabling and disabling editor fields</li>
</ul>
<button id='submit'>Submit (console.log)</button>
<button id='restore'>Restore to Default</button>
<button id='enable_disable'>Disable/Enable Form</button>
<span id='valid_indicator'></span>
<div id='editor_holder'></div>
<script>
// This is the starting value for the editor
// We will use this to seed the initial editor
// and to provide a "Restore to Default" button.
var starting_value = [
{
name: "John Smith",
age: 35,
gender: "male",
location: {
city: "San Francisco",
state: "California",
citystate: ""
},
pets: [
{
name: "Spot",
type: "dog",
fixed: true
},
{
name: "Whiskers",
type: "cat",
fixed: false
}
]
}
];
// Initialize the editor
var editor = new JSONEditor(document.getElementById('editor_holder'),{
// Enable fetching schemas via ajax
ajax: true,
// The schema for the editor
schema: {
type: "array",
title: "People",
format: "tabs",
items: {
title: "Person",
headerTemplate: "{{i}} - {{self.name}}",
oneOf: [
{
$ref: "basic_person.json",
title: "Basic Person"
},
{
$ref: "person.json",
title: "Complex Person"
}
]
}
},
// Seed the form with a starting value
startval: starting_value,
// Disable additional properties
no_additional_properties: true,
// Require all properties by default
required_by_default: true
});
// Hook up the submit button to log to the console
document.getElementById('submit').addEventListener('click',function() {
// Get the value from the editor
console.log(editor.getValue());
});
// Hook up the Restore to Default button
document.getElementById('restore').addEventListener('click',function() {
editor.setValue(starting_value);
});
// Hook up the enable/disable button
document.getElementById('enable_disable').addEventListener('click',function() {
// Enable form
if(!editor.isEnabled()) {
editor.enable();
}
// Disable form
else {
editor.disable();
}
});
// Hook up the validation indicator to update its
// status whenever the editor changes
editor.on('change',function() {
// Get an array of errors from the validator
var errors = editor.validate();
var indicator = document.getElementById('valid_indicator');
// Not valid
if(errors.length) {
indicator.style.color = 'red';
indicator.textContent = "not valid";
}
// Valid
else {
indicator.style.color = 'green';
indicator.textContent = "valid";
}
});
