jQuery（或任何Web工具）嵌套表达式生成器 [英] jQuery (or any web tool) Nested Expression Builder

问题描述

我想将一个功能添加到我正在开发的Web应用程序中，以允许用户使用表达式构建器创建规则。例如Magento中使用的图片（下面的链接中的图片）。

代码： https://github.com/chrisjpowers/business-rules

I would like to add a feature to a web app I am developing to allow the user to create rules with an expression builder. Such as the one used in Magento (picture in link below).

I want to allows them to be able to create the expressions or if statements using column names from a table in a Database, then be able to do comparisons and what not. The expression built in the user interface would then evaluate to code that would be evaluated by a PHP script or Javascript or Perl

I searched the web for things like this that are javascript (ajax) based. I figures there has to be a module or something out on the internet somewhere for jQuery or something similar, but I haven't been able to find anything. I am also not quite sure what something like this is called besides "Expression Builder". If there is something like this out there it would save me a lot of time compared to writing it from scratch.
