Problems solved by technology

However, since IE8 and browsers below IE8 do not support the object.defineProperty attribute, they cannot monitor the get / set attribute of variables, and cannot assign values ​​to variables through conventional '=' to achieve the effect of changing the view. Therefore, it is impossible Realize two-way data binding of browsers of IE8 and versions below IE8

Abstract

The present application provides a method and device for bidirectional binding of data, a terminal and a storage medium. the processing module receives the data change notification sent by the subscription module, updates the data according to the data change notification and sends the view update instruction to the view update module, the view update module updates the view related to the data according to the view update instruction; The monitoring module monitors the user interaction event and sends the data change triggered by the interaction event to the processing module, The processingmodule updates the data according to the data change triggered by the interactive event and sends a view update instruction to the view update module. The view update module updates views related to the data according to the view update instruction. The method can realize the data bidirectional binding of the browsers of the IE8 and below versions.

Description

technical field [0001] The present application relates to the technical field of web front-end and visualization, and in particular to a method, device, terminal and storage medium for two-way data binding. Background technique [0002] Two-way binding, that is, two-way binding between the data model (Model) and the UI view (View), specifically manifested in that the user's modification on the view will be automatically synchronized to the data model. Similarly, if the value in the data model If there is a change, it will be synchronized to the view immediately. The most common application scenario is the operation of the form. When the user completes the input or click on the front-end page, the data is automatically stored in the data model without any operation. At present, the commonly used methods for two-way data binding include dirty check mechanism and data hijacking. The dirty check mechanism is used in the Angular framework, but the Angular reference is large, and...
