在 ColdFusion 中使用表单数组? [英] Working with Form Arrays in ColdFusion?

问题描述

我不知道如何在 ColdFusion 9 中处理这个问题，我提交了一个带有元素复选框的表单 (POST)，称为 items[].

I have no idea how to handle this in ColdFusion 9, I have a form being submitted (POST) with element checkboxes, called items[].

当我执行 <cfdump var="#form#"/> 没有问题时，我会得到所有显示正确名称的项目，例如 items[] 例如:

When I do a <cfdump var="#form#" /> no-problem, I get all the items shown with the proper names like items[] eg:

struct 
ITEMS[] 13,14  
FIELDNAMES ITEMS[] 

但是执行 <cfdump var="#form.items[]#"/> 会导致错误.如何访问 CF9 字段值?以某种方式循环它?

however doing a <cfdump var="#form.items[]#" /> results in an error. How do I access the CF9 field values? Somehow loop through it?

我似乎无法对数组做任何事情来从中获取 id?想法?我有点难过，ColdFusion 并不是最容易在网上找到示例/参考的语言.;)

I cannot seem to do anything with the array to get the id's out of it? Thoughts? I'm kind of stumped and ColdFusion isn't the easiest language to find examples / references on the net. ;)

有没有正确的方法来处理这个问题?我需要从那里取出 ID，以便我可以参考在表单中检查了哪些行，以便我可以采取后续行动.

Is there a correct way to deal with this? I need to get the ID's out of there so I can reference what lines were checked in the form, so I can follow up with an action.

谢谢！

推荐答案

ColdFusion 中没有表单数组.以 '[]' 结尾并不能使其成为数组.您可以像这样从表单范围访问复选框值:

There's no Form Array’s in ColdFusion. Having '[]' at the end doesn't make it an array. You can access the checkbox values from form scope like this:

FORM["ITEMS[]"]

由于 '[]' 的原因，点表示法不起作用.请参阅:http://help.adobe.com/en_US/ColdFusion/9.0/开发中/WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html

Dot notation doesn't work 'cause of the '[]'. See: http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-7fb2.html

复选框中的值只是逗号分隔的值，在 ColdFusion 中是一个列表

Values from checkboxes are just comma separated values, which is a List in ColdFusion

要遍历它，请使用 cfloop list=:

To loop through it, use cfloop list=:

<cfoutput>
  <cfloop index="i" list="#FORM['ITEMS[]']#">    
    #i#
  </cfloop>
</cfoutput>

要将列表转换为数组，请使用 ListToArray().有 listGetAt() 之类的列表函数，但如果您要进行大量随机访问，最好先将列表转换为数组.

To convert a list to array, use ListToArray(). There are list functions like listGetAt(), but if you're doing lots of random access, it'd be smarter to convert the list into an array first.

想想，我有点难过Coldfusion 不是最简单的语言查找示例/参考净;)
