Coldfusion - 如何循环通过结构数组，并动态打印所有KEY值？ [英] Coldfusion - How to loop through an Array of Structure and print out dynamically all KEY values?

问题描述

提供结构数组：

我可以通过执行以下操作打印所有字段的所有值：

I am able to print out all values from all fields by doing:

    <cfset ColumnNames  = structKeyArray(ApiData[1])>                       
    <cfset ColumnLength = ArrayLen(ColumnNames)>    

    <cfloop from="1" to="#ArrayLen(ApiData)#" index="i">            
       <cfdump var="#ApiData[i].Created#">              
       <cfdump var="#ApiData[i].Name#">
               ...and so on

现在我试图遍历所有字段我不必实际写入每个字段的
名称。我如何动态地这样做？
类似：

Now I am trying to loop through all fields so that I dont have to actually write the name of each field. How do I do this dynamically? Something like:

    <cfloop from="1" to="#ArrayLen(ApiData)#" index="i">    
      <cfloop from="1" to="#ColumnLength#" index="i">
              <!---<cfdump var="#ApiData[i]." + "#ColumnNames[i]#" + "#">--->
              <!---<cfdump var="#ApiData[i].ColumnNames[i]#">--->
      </cfloop>
    </cfloop>

我不是ColdFusion的家伙，只是帮助一个好友，ColdFusion语法与.Net ： - ）

I am not a ColdFusion guy, just helping a buddy and the ColdFusion syntax is very different from .Net :-)

感谢您的帮助

推荐答案

<cfloop from="1" to="#arrayLen(ApiData)#" index="i">
  <cfset data = ApiData[i]>
  <cfloop collection="#data#" item="key">
    #key#:#data[key]#
  </cfloop> 
</cfloop>

或者你可以使用CFScript，这应该更容易拿起。

Or you can use CFScript, which should be much easier to pick up.

for (d in ApiData)  // for-in loop for array
{
  for (key in d)  // for-in loop for struct
  {
     writeOutput(key & ":" & d[key]);
  }
}
