问题描述

我想一个功能添加到Web应用程序，我正在开发允许用户与前pression建设者创建规则。如在Magento（图片下面链接）。用一个

我希望让他们能够创建前pressions或者如果数据库使用的列名从一个表的语句，然后可以做比较，什么不是。建在用户界面的EX pression然后将计算结果为code将由PHP脚本或JavaScript或Perl

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

我在网上搜索基于这样的事情是JavaScript的（阿贾克斯）。我人物必须有一个模块或东西在互联网某处的jQuery或类似的东西，但我一直没能找到任何东西。我也不太清楚这样的事情被称为除了前pression生成器。如果有这样的事情在那里它可以节省我很多时间相比，从头开始编写它。

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.
