ready

static event

This event is fired when the FroalaCharts library is ready to be used. By the time this event is raised, the browser's DOM is ready to be interacted with, which corresponds to the DOMContentLoaded event of browsers. In older browsers, where DOMContentLoaded is not fired, the ready event corresponds to the load event of the page. In case the FroalaCharts library is included in the page when the DOMContentLoaded event is already fired (i.e. the script is loaded asyncronously using AJAX or by using script deferring methods) the ready event is still fired to ensure integrity of all the listeners.

In many ways the nature of this event is similar to the jQuery(document).ready function of the jQuery library and the Ext.onReady function of the ExtJS library. One should interact with the FroalaCharts framework (i.e. create new charts, set options, etc.) only after this event has been fired. This event also helps you to neatly write your code in separate script files and in the page <head> thus keeping scripts from being a part of your page <body>.

An alternate (and shorthand) method to subscribing the ready event is to use the ready function. One advantage that the ready function has over the ready event is that the event is fired only once during the life-cycle of a page while functions passed to the ready function are executed even when attached after the ready event has been fired.

This is a framework level event and as such can be only listened via the FroalaCharts object on the FroalaCharts class alone. It will not be fired if it is subscribed from individual chart instances.

Event Object Parameters

eventType

Type: string

Type (name) of the event triggered

eventId

Type: number

Unique ID associated with the event. Internally, it is an incrementing counter that can also be used to verify the order in which the event was triggered.

sender

Type: FroalaCharts

Instance of the FroalaCharts object that fired this event. Events that are fired by the framework (and not by individual charts) have the framework as this property.

cancelled

Type: boolean

Boolean attribute that indicates whether an event's propagation was cancelled; set to true when eventObj.stopPropagation() is called.

stopPropagation

Type: function

Function called from within a listener to prevent subsequent listeners from being executed.

defaultPrevented

Type: boolean

Boolean attribute that indicates whether the default action of the event was defaultPrevented; set to true when eventObj.preventDefault() is called.

preventDefault

Type: function

Function to prevent the default action of an event. For example, if the eventObj.preventDefault() function is called for the beforeResize event, the chart will not be resized and the resizeCancelled event will be triggered.

detached

Type: boolean

Boolean attribute that indicates whether a listener has been detached and will no longer be executed; set to true when eventObj.detachHandler() is called

detachHandler

Type: function

Function to allow the listener to remove itself rather than being called externally by the removeEventListener() method. It is useful for one-time event listening or for special situations when the event is no longer required to be listened when it has been triggered with a specific condition.

now

Type: boolean

Boolean attribute to indicate whether the event was triggered at the instant of the window.ondomcontentloaded event ( window.onload for older browsers) or whether the window was already loaded and the event was fired to maintain integrity

Example

<html>
	<head>
<script type="text/javascript" src="/froalacharts/js/froalacharts.js"></script>
<script type="text/javascript">

        renderAt: 'chart-container-div',
        dataFormat: 'json',
        dataSource: {
            chart: {
                caption: "Quarterly sales summary",
                numberPrefix: "$"
            }

            ]
        }
    });
    // Since we are in the `ready` block, the `chart-container-div`
    // element should be available by now.
    chart.render();
});
</script>
<body>
    <div id="chart-container-div">Chart loads here...</div>
</body>
</html>

beforeInitialize

static event

This pre-initialization event is triggered every time a new instance of the FroalaCharts object is created. It then triggers a number of modules that need to be setup on every instance of FroalaCharts; the event can be used to perform any actions required to be completed before the initialization of each chart.

Because this event is triggered upon instantiating a new FroalaCharts object, it is virtually impossible to listen to this event by adding an event listener to the chart. By the time the event listener is attached (using the addEventListener() method), the event is already fired.

However, there are alternate ways that can be used to listen to this event. You can listen to the FroalaCharts global events, using the addEventListener static method before even creating a new instance. (The required instance can be identified by the id of the chart using eventObject.sender.id.) You can also pass the event listener as a parameter of the FroalaCharts constructor.

rendered

The event is fired when the chart completes drawing, after the FroalaCharts#render() or the FroalaCharts#chartType() method is called. The chart renders if the data provided is correct; otherwise, an error message is rendered.A call to this event is made only once, even if new data may be supplied later. It can be used to invoke any further JavaScript methods on the chart or to change chart data.

If chart animation is enabled, this event is triggered before the animation process. In case you need to perform any action after the animation has completed, you will need to add an appropriate time delay in this event handler, for example, by using setTimeout .

ready

This event is fired when the FroalaCharts library is ready to be used. By the time this event is raised, the browser's DOM is ready to be interacted with, which corresponds to the DOMContentLoaded event of browsers. In older browsers, where DOMContentLoaded is not fired, the ready event corresponds to the load event of the page. In case the FroalaCharts library is included in the page when the DOMContentLoaded event is already fired (i.e. the script is loaded asynchronously using AJAX or by using script deferring methods) the ready event is still fired to ensure the integrity of all the listeners. In many ways the nature of this event is similar to the jQuery(document).ready function of the jQuery library and the Ext.onReady function of the ExtJS library. One should interact with Froala Charts (i.e. create new charts, set options, etc.) only after this event has been fired. This event also helps you to neatly write your code in separate script files and in the page <head> thus keeping scripts from being a part of your page <body> An alternate (and shorthand) method to subscribing the ready event is to use the FroalaCharts.ready function. One advantage that the ready function has over the ready event is that the event is fired only once during the life-cycle of a page while functions passed to the ready function are executed even when attached after the ready event has been fired. This is a library level event and as such can be only listened via the FroalaCharts object on the FroalaCharts class alone. It will not be fired if it is subscribed to from individual chart instances.

beforeInitialize

This pre-initialization event is fired every time a new instance of FroalaCharts is created. It then triggers a number of modules that need to be setup on every instance of FroalaCharts; the event can be used to perform any actions required to be completed before the initialization of each chart. Because this event is triggered upon instantiating a new FroalaCharts object, it is impossible to listen to this event by adding an event listener to the chart. By the time the event listener is attached (using the FroalaCharts#addEventListener method), the event will already have been already fired. However, there are alternate ways that can be used to listen to this event. You can listen to the FroalaCharts global events, using the FroalaCharts.addEventListener static method before even creating a new instance. The required instance of FroalaCharts can then be identified from within the event handler by using event.sender.id . You can also pass the event listener for the correct event within the events object when creating an instance of FroalaCharts

stopPropagation

Type: function

Function called from within a listener to prevent subsequent listeners from being executed

defaultPrevented

Type: boolean

Boolean attribute that indicates whether the default action of the event was prevented; set to true when eventObj.preventDefault() is called.

preventDefault

Type: function

function to prevent the default action of an event. For example, if the eventObj.preventDefault() function is called for the beforeResize event, the chart will not be resized and the resizeCancelled event will be triggered.

detached

Type: boolean

Boolean attribute that indicates whether a listener has been detached and will no longer be executed; set to true when eventObj.detachHandler() is called.

detachHandler

Type: function

Function to allow the listener to remove itself rather than being called externally by the removeEventListener() method. It is useful for one-time event listening or for special situations when the event is no longer required to be listened when it has been triggered with a specific condition.

disposed

Usually, this event is fired by the FroalaCharts#dispose() method. FroalaCharts also triggers it when an already rendered chart is re-rendered. Unused charts should always be disposed to avoid memory-leaks within an application or dashboard.
