Node interception method, system and equipment based on rich text and storage medium

Abstract

The invention belongs to the technical field of text interception, and particularly discloses a node interception method based on a rich text. The method comprises the following steps: acquiring a DOM node of an original rich text; generating an object tree by serializing DOM nodes; calculating the number of texts through a recursive node object tree, and traversing a node object tree array; when counting meets the expected number of intercepted texts, intercepting the text content, jumping out of circulation, and intercepting the remaining DOM object tree; deserializing the DOM object tree into DOM nodes, and traversing the DOM object tree; calling an innerHTML method of the DOM node to generate a rich text with a reserved style; uploading the rich text with the reserved style to a server side; and after the user side obtains the rich text, directly setting an innerHTML method of the DOM to render, so accurate interception can be completed. Through the method for serializing the DOM tree, the rich text can be intercepted according to the word number, and the style can be reserved.

Description

technical field [0001] The invention belongs to the technical field of text interception, in particular to a rich text-based node interception method, system, device and storage medium. Background technique [0002] Modern article editing is basically based on rich text editors, rich text editors, Rich Text Editor, RTE for short, is a text editor that can be embedded in a browser, what you see is what you get. It is a text editor that solves the problem that ordinary users can use different HTML and other web page tags but need to set font color, size, style and other information on the web page. [0003] With the popularity of scenarios such as paid knowledge articles, most paid articles are based on the interception of rich text paragraphs, such as get, WeChat paid articles, get paid reading and other applications. But the problems encountered in the interception based on paragraph in the prior art are as follows: [0004] 1. It is impossible to accurately capture the sp...

AI Technical Summary

Problems solved by technology

[0004] 1. It is not possible to accurately intercept the specific amount of text, and can only be intercepted according to paragraphs

[0005] 2. The style and text are separated, and the front end needs to be processed separately

[0006] 3. The background editing page, back-end storage, and user display all need to be modified to varying degrees
