我创建了几个查询，根据一组略有不同的变量生成相同的数据：

Hi, I have created several queries which produce the same data based on a slightly difference set of variables:

展开 | 选择 | Wrap | 行号 推荐答案

这可能是一个JavaScript问题，但您可以使用< cfif>来使用相同的查询。决定使用哪个额定功率。 你想一次只显示一个数字集，还是全部都要显示？此外，更改是否必须立即发生，还是页面卸载/重新加载不是问题？ This would be more of a JavaScript question, but you could use the same query using <cfif> to decide which power rating to use. Do you want only one number set to be displayed at a time, or would the whole lot do? Also, does the change have to happen instantly or is a page unload/reload not a problem?

hi Acoder， 我将如何实现这个？我只希望它一次显示一个数字变化，但显然想让用户选择更改它（无论是点击数字还是从下拉列表框中选择标准）。 我需要立即更新。 hi Acoder, how would I achieve this? i only want it to display one number change at a time, but obviously want to give the user the choice of changing it (whether clicking on the number or selecting the criteria from a drop down list box). I need instantaneous update really.

您至少有两个选择： 1.加载所有数据进入JavaScript数据结构，例如用于更新表的数组。使用Coldfusion生成JavaScript代码。 2.使用Ajax。向Coldfusion页面发出一个Http请求，该页面获取传递参数的正确数据。 哪一个你会更舒服？ 注意：Coldfusion 8有一些Ajax标签，但我个人还没有真正研究过它们，因为我对JavaScript / Ajax很满意。 You have at least two choices: 1. Load all the data into JavaScript data structures, e.g. arrays to use to update the table. Use Coldfusion to generate the JavaScript code. 2. Use Ajax. Make a Http request to a Coldfusion page which gets the correct data for the passed parameter. Which one would you be more comfortable with? Note: Coldfusion 8 has a few Ajax tags, but I personally haven''t really looked into them, because I''m quite comfortable with JavaScript/Ajax.
