Return Value

Examples

The following example demonstrates how to create and dispatch a custom event that bubbles and cannot be canceled.

var evt = document.createEvent("Event");
evt.initEvent("custom", true, false);
document.getElementById('target').dispatchEvent(evt);

To respond to the custom event created previously, the following example adds an event handler that interacts with the event by setting a expando property named detail.

function reportEvent(evt) {
    evt.detail = "Success.";
}
var p = document.getElementById('target');
p.addEventListener("custom", reportEvent, false);

Notes

If the event object is to be dispatched with dispatchEvent, the appropriate event initialization method must be called. For example, after creating an event of type UIEvent, call initUIEvent to initialize the event object’s values. **Security Warning: **For security reasons, events generated with createEvent are untrusted and have a isTrusted value of false.
