Implementation of Complex Formula Editor Based on Web

In the Web applications it is difficult to directly edit the complex mathematical formula online, which has greatly affected the full application of physics, mathematics. At present, there are some alternative solutions, but they have some kinds of flaws not to widely apply. In this paper, the mathematical formula editor of MSOFFICE WORD is called to combine with XML markup language to be fully compatible with the formula edited in the WORD. This method not only is intuitive and practical, but also can implement the function of inputting formula by handwriting online.
