Window.convertPointFromPageToNode - Web APIs 编辑

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Given a Point specified in the page's coordinate system, the Window method convertPointFromPageToNode() returns a Point object specifying the same location in the coordinate system of the specified DOM Node.

Please review the Browser compatibility section before using this method, as it's not widely supported (nor is the Point object it uses).

Syntax

Point = Window.convertPointFromPageToNode(node, pagePoint);

Parameters

node

The Node into whose coordinate system the point is to be converted.

pagePoint

A Point object specifying a point in the coordinate system of the page, which is to be converted into the node's coordinate system.

Return value

A Point object describing the specified location in the node's coordinate system.

Specifications

This method was specified in the defunct 20 March 2009 Working Draft of CSS 2D Transforms Module Level 3. It is not present in the current CSS Transforms Module Level 1 Working Draft.

Browser compatibility

BCD tables only load in the browser
