Problems solved by technology

Instant messaging mainly transmits text and picture information. When exchanging existing information on the Internet, users need to perform operations such as copying and pasting, which is not convenient to use.
The co-browsing method can directly perform annotations and other operations on existing documents, but the current co-browsing mainly works in a "publish-subscribe" mode, which has poor real-time performance and is difficult to achieve instant communication

Embodiment Construction

[0027] Specific embodiments of the present invention are described below.

[0028] A kind of DOM-based and XMPP web page real-time cooperative browsing method of the present invention is concretely realized as follows:

[0029] 1 Acquisition of co-browsing information

[0030] a1. Node information acquisition

[0031] DOM is an API (Application Programming Interface) for HTML and XML documents. DOM depicts a hierarchical node tree, allowing developers to add, remove and modify a certain part of the page. And can gain access to the node. Such as Figure 1 shown.

[0032] When the user clicks on a certain position on the web page, an onclick event will be triggered on the node, and it will be triggered in turn along the DOM tree all the way up on each node on the path until it bubbles up to the document (Document) node. When the onclick event is triggered in a specific situation we stipulate, the nodes that are triggered sequentially will be stored in a stack. Since all v...

Abstract

The invention discloses a webpage instant collaborative browsing method based on a DOM (document object model) and an XMPP (extensible messaging and presence protocol). In the method, by organically combining the instant messaging and a collaborative browsing mode, the collaborative browsing information is transmitted in an instant messaging mode, a user can quickly realize instant collaborative browsing of webpage with another user while browsing the webpage, a dialogue box can be opened in any position of the webpage, and the webpage can be marked at will. In terms of collaborative browsing, the method extracts the collaboration information based on the DOM, has small information transmission quantity, is widely supported by the mainstream browsers and can adapt to different display terminals of the user to ensure the accuracy of the collaboration information; and in terms of instant messaging, the method transmits information based on an XMPP mode, wherein the XMPP is an open-source messaging protocol widely adopted by the Internet companies and can realize seamless interaction with the mainstream instant messaging networks of GTalk (Google Talk) and MSN (Microsoft service Network).

Description

technical field [0001] The invention relates to a real-time collaborative browsing technology capable of realizing the acquisition, transmission and restoration of webpage marked content and chat information. In particular, it relates to a web page instant collaborative browsing method based on DOM (Document Object Model) and XMPP (The Extensible Messaging and Presence Protocol). Background technique [0002] With the rapid development of Internet technology, the Internet has gradually become an indispensable part of people's lives. Various Internet applications have also sprung up. The Internet connects people together, whether it is online entertainment or network conferences, etc., it is often necessary to provide the ability to comment and interact with public information on the Internet. This interactive capability is currently mainly realized through instant messaging and collaborative browsing. [0003] Both approaches have advantages and disadvantages. Instant me...
