Problems solved by technology

However, not all browsers currently support the HTML5 standard. For example, IE6 and IE7 not only do not support HTML5, but also do not support this inter-domain message transmission mechanism.
Therefore, the postMessage message transmission mechanism cannot be used by IE6 and IE7, which account for a large market share, for cross-domain communication.

Abstract

Disclosed is a browser message transmitting device, comprising a standard message transmitter, a first determination unit, and a customized message transmitter; the standard message transmitter transmits a to-be-transmitted source webpage message to a target webpage in an inter-network-domain message transmitting manner; the first determination unit determines whether a browser supports an inter-network-domain message transmission mechanism; if yes, then transmitting the to-be-transmitted source webpage message to the standard message transmitter; if no, then transmitting the to-be-transmitted source webpage message to the customized message transmitter; and the customized message transmitter transmits the to-be-transmitted source webpage message to the target webpage by modifying the specific attribute value of the target webpage. Moreover, also provided is a message transmitting method. Correspondingly, also provided are a message receiving device and method, and a browser communication system and method.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a message sending device and method in a browser, a message receiving device and method, and a communication system and method in a browser. Background technique [0002] Today, in order to enhance the performance of Web pages, many browsers have begun to adopt HTML5 technology. HTML5 technology is a set of technology combinations including previous HTML, CSS and JavaScript. [0003] JavaScript is a front-end dynamic scripting technology often used in web development. In JavaScript, there is a very important security restriction called "Same-Origin Policy" (Same-Origin Policy). This strategy imposes important restrictions on the page content that JavaScript code can access, that is, JavaScript can only access content under the same domain as the document containing it. [0004] The security strategy of JavaScript is particularly important when performing multi-iframe ...
