Easyui parser and easyui parser
When writing code, it is found that if the html code is not written on the page, but the corresponding component is added when a method is executed after the page is loaded, after being added, easyui will not initialize this component for you.

This article quoted: http://www.ibm.com/developerworks/cn/java/j-lo-compose/ Ward Cunningham once said that clean code clearly expresses what the code writer wants to express, while the graceful code is a step further, and the graceful code looks like it exists specifically for the problem to be solved. In this article, we will show a modular parser design, implementation process, the final code is graceful, very extensible, like to parse a particular
Recently reading the prestigious "Dragon book", read the section of the grammatical analysis, about the compiler of the grammatical Analysis section, Dragon book mainly on the top-down grammar analysis and bottom-up analysis of two types of parsing methods, top-down grammar analysis mainly corresponds to ll grammar, and the bottom-up of the grammatical analysis mainly corresponds to the LR grammar, The details of the grammar are not discussed here. This paper mainly discusses the advantages and
