针对现有基于静态分析的JavaScript代码推荐技术准确度低且响应速度较慢的问题，提出一种基于动态分析的JavaScript代码提示方法，并设计基于Eclipse插件的代码推荐工具。采用事先建模的方法保存模拟运行环境，并且对上下文对象建立特征索引。同时在用户代码抽象语法树的基础上进行代码分块，按程序分块顺序对用户代码进行模拟执行，利用对象之间的相似度在用户运行时修正运行变量，并对模拟执行时产生的异常进行处理，实现针对用户代码的动态分析JavaScript代码提示。实验结果表明，与现有使用静态分析方法的JavaScript代码推荐技术相比，该方法具有更高的可推荐性和更快的响应速度。

Aiming at the problem of low precise and slow response in the state of JavaScript code recommendation technology,this paper introduces a JavaScript code recommendation method based on dynamic analysis and implements a code recommendation plug-in for Eclipse. This approach builds model offline for storing the simulated runtime environment,and creates indexes for all objects in the environment. It simulates executing user code, while applying abstract syntax tree of user code for blocking and updating undefined variables at runtime,to achieve a JavaScript code recommendation tool based on dynamic analysis. Compared with current code proposal tools with static analysis, experiments show the tool improves both the precise and response time.
