#getElementById()

#Introduction

getElementById is a method for finding elements' reference based on a specified id in the current page. This method takes an id selector as the parameter and returns a reference to the corresponding element's reference. Please note that this reference does not allow background threads to hold the elements; background threads can only use this reference to inter thread call element methods across threads, and this reference does not affect the element's lifecycle.

#Syntax

let element = lynx.getElementById(id);

#Parameter

#id

A String type, the id selector of the element to be obtained.

#Return Value

Returns a NodeRef: If the corresponding element is found, a reference to the element is returned; if no corresponding element is found, null is returned.

#Example

let ele = lynx.getElementById('id');
