#__SetEvents

#Introduction

Sets event listeners for a specific Element node.

#Syntax

__SetEvents(element: Element, listeners: Array<Record<string, any>>) : void;

#Parameters

• type: A case-sensitive string representing the event type to listen for.
• name: A case-sensitive string representing the event name to listen for.
• function: The function can be a case-sensitive string or null/undefined.
  • When the function is a case-sensitive string, the Lynx SDK will send the current Element's parentComponentUniqueID, function, and event to the background thread to call the corresponding entry function when the event is triggered.
  • When the function is null or undefined, the Lynx SDK will remove the corresponding listener based on the type and name from the Element object's listeners.

#Return Value

No return value.

#Example

The frontend framework can generate render instructions as follows.

<view src="xxx" bindtap="onTap" />

// main-thread.js
let element = __CreateElement('view', 0, {});
__SetAttribute(element, 'src', 'xx');

__SetEvents(element, [{ type: 'bindEvent', name: 'tap', function: 'onTap' }]);
