Coldfusion - 如何循环遍历结构数组并动态打印出所有键值? [英] Coldfusion - How to loop through an Array of Structure and print out dynamically all KEY values?

问题描述

给出下面的结构数组:

我可以通过以下方式打印出所有字段中的所有值:

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

现在我正在尝试遍历所有字段，这样我就不必实际编写每个字段的名称.我如何动态地做到这一点?比如:

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 人，只是帮助朋友，ColdFusion 的语法与 .Net 非常不同 :-)

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，应该更容易上手.

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]);
  }
}
