Problems solved by technology

[0002] In the prior art, the software for drawing chemical small molecules embedded in Web applications is usually an Applet program developed based on Java. This type of software is bulky and slow, and requires users to install third-party programs
However, many Javascript-based lightweight Web small molecule drawing software developed abroad can only draw accurate molecular structures with simple query functions, but cannot draw molecular structures with complex query functions, and the functions are not perfect; and usually they are not fully compatible. For old browsers, such as Internet Explorer 6.0, and the market share of this type of browser in my country reaches 30%

Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 It is a schematic flowchart of the JavaScript-based method for drawing chemical small molecules on the Web of the present invention. Such as figure 1 As shown, the JavaScript-based method for drawing chemical small molecules on the Web of the present invention specifically includes the following steps:

[0035] S11: Capture the user's molecular drawing action on the drawing interface;

[0036] In this step, the capture method and the drawing interface of the molecular drawing action are compatible with current mainstream browsers; for IE series browsers, the drawing interface is displayed using VML (Vector Markup Language, Vector Markup Language) vector markup language, The capture and positioning method of the molecular drawing action adopts the unique coordinate calculation method of IE; for other standard browsers, the di...

Abstract

The invention discloses a method for drawing chemical micro molecules on Web based on Java Script. The method includes the following steps: S11 capturing molecule drawing action of a user on a drawing interface; S12 analyzing the captured molecule drawing action into characteristic attribute of a molecule image to be displayed on the drawing interface; S13 analyzing the characteristic attribute of the molecule image to be displayed on the drawing interface and calculating a route coordinate and the rendering style of the molecule image to be mapped based on chemical reasonability; S14 generating scalable vector graphic (SVG) or vector markup language (VML) character strings required by page display according to the obtained route coordinate and the rendering style and displaying the molecule image on the drawing interface; S15 exporting the molecule image displayed on the drawing interface into a text of a machine-oriented language (MOL) format. A system for drawing the chemical micro molecules on the Web based on the Java Script is further disclosed.

Description

technical field [0001] The invention belongs to the field of chemical informatics, in particular to a JavaScript (Java scripting language)-based method and system for drawing small chemical molecules on the Web (web page). Background technique [0002] In the prior art, the software for drawing small chemical molecules embedded in the Web application is usually an Applet program developed based on Java. This type of software is bulky and slow, and requires users to install third-party programs. However, many Javascript-based lightweight Web small molecule drawing software developed abroad can only draw accurate molecular structures with simple query functions, but cannot draw molecular structures with complex query functions, and the functions are not perfect; and usually they are not fully compatible. For old browsers, such as Internet Explorer 6.0, and the market share of this type of browser in our country has reached 30%. Contents of the invention [0003] The technic...
