NodesRef

Introduction

Node information.

Method Parameters

Method	Parameters	Description
boundingClientRect	Function callback	Adds a query request for the layout position of a node relative to the display area (unit: pixels). It functions similarly to getBoundingClientRect in the DOM. The return value is the selectorQuery corresponding to the nodesRef.
fields	Object fields, Function callback	Retrieves relevant information about a node, with specific fields to be obtained specified in the fields parameter. The return value is the selectorQuery corresponding to the nodesRef.
scrollOffset	Function callback	Adds a scroll position query request for a node (unit: pixels). The node must be a scroll-view or viewport. The return value is the selectorQuery corresponding to the nodesRef.

Sample Code

Page({
  onReady() {
    let node = dlt.createSelectorQuery();
    // Node's position information, for regular nodes
    node.select('node').boundingClientRect((rect) => {});
    // Node's relevant information, for regular nodes
    node.select('node').scrollOffset().exec();
    // Node's scroll position information, for special nodes
    node.select('node').fields().exec();
  },
});
