Abstract

The invention discloses a focus query method for an embedded browser. The focus query method comprises the following steps of determining a DOM (document object model) tree corresponding to a current node according to the current node; determining a rectangular range in which the current node is positioned according to the position information of the current node in a rendering tree corresponding to the DOM tree; traversing the DOM tree according to the rectangular range so as to obtain a first candidate node; continuously traversing the DOM tree, inquiring residual nodes in the DOM tree, and determining a target node; moving step length N according to a preset focus so as to determine a target focus when the target node is one of effective nodes except the current node. According to the focus query method for the embedded browser, the manipulation of webpages of an intelligent television effectively becomes simpler and more convenient, so that the user experience degree is greatly improved.

Description

technical field [0001] The invention relates to embedded browser technology, in particular to an embedded browser focus query method. Background technique [0002] As an open source browser engine, Webkit has a clear source code structure, extremely fast rendering speed, high efficiency, stability, and good compatibility. Currently, most embedded devices use this engine. However, its original design was aimed at PC terminals and touch-screen mobile terminals, and did not make a separate design for the remote control control page. [0003] Because on PC devices, users generally use a mouse or trackball to operate pages, but smart TVs generally use remote controls. Currently, when simply using keyboards or remote control buttons for navigation operations, normal movement of the focus cannot be achieved. Even from the perspective of a computer keyboard, the navigation function of simply using the Tab key still has great limitations. Although a focus processing framework is de...
