Research status of formula editor;

With the rapid development of the Internet, obtaining, publishing and enjoying information resources through the Internet has become the basic means of people's work, study, research and communication. Mathematics is the basic language of science and technology, and it is more urgent for education and scientific research to solve the problem of editing mathematical formulas based on web pages.

In fact, it has always been a major problem that people are committed to solving, and counterparts in various countries have also given some technical solutions. Taken together, it can be divided into three categories: the first category is mainly picture display; The second is based on MathML (Mathematical Markup Language) to mark mathematical formulas. The third category is editing and displaying based on HTML language.

1, based on image display

The first mode is divided into two types: ordinary static picture display and dynamic picture display. The former uses some software (such as Word, etc. ) make pictures of mathematical formulas and upload them to the network server. The main disadvantage of this method is that it takes up a lot of network resources and formula data cannot be reused.

The latter is that the server dynamically generates pictures after receiving the formula comment information and sends them to the network terminal. However, formula comment information can only be understood and used through in-depth study, which is very inconvenient for network interaction. It occupies a large number of network servers and network transmission resources, and cannot adapt to large concurrent network interactive applications.

In addition, the use of pictures will also bring other problems. For example, although high-quality pictures are clearly printed, they will affect network transmission, while low-quality pictures are not clearly displayed and printed.

2. Markup language based on mathematical formula.

The second way needs to be displayed in a browser that supports MathML, but the dominant IE browser in the market does not support MathML. According to the information collected on the website of the Internet Society (W3C), it is necessary to install additional software or plug-ins to realize the scheme of displaying and editing mathematical formulas in the mainstream IE browser.

3. Based on HTML language.

MathML is not widely used because it needs to install plug-ins. Then there is no need to install an online formula editor with plug-ins. This editor is represented by JMEditor.

JMEditor(JavaScript Math Editor) is a lightweight, open source, WYSIWYG online formula editor, based on components such as CKEditor, jQuery, MathQuill, etc., without any plug-ins.

CKEditor and jQuery are widely used, so I won't introduce them too much. What needs to be pointed out is MathQuill, who used HTML+CSS+JS to achieve the effect of formula editing, and he exerted the power of dom to the extreme.

However, MathQuill is not perfect, and it is implemented according to LaTeX grammar, but some complex effects are not realized, such as matrix.
