ColdFusion的 - 如何通过结构并打印出动态的所有关键值的数组循环？ [英] Coldfusion - How to loop through an Array of Structure and print out dynamically all KEY values?

问题描述

捐赠以下结构的数组：

我能够做打印出来自各个领域的所有值：

 ＆LT; CFSET COLUMNNAMES = structKeyArray（ApiData [1]）＆GT;
    ＆LT; CFSET ColumnLength = ArrayLen（COLUMNNAMES）GT;    ＆LT;从=1=＃ArrayLen（ApiData）＃指数=我＆GT CFLOOP;
       ＆LT; cfdump VAR =＃ApiData [I] .Created＃＆GT;
       ＆LT; cfdump VAR =＃ApiData [I] .Name点＃＆GT;
               ...等等
 

现在，我通过各个领域的尝试循环，这样我不必实际写入
命名每个字段。如何动态地做到这一点？
是这样的：

 ＆LT;从=1=＃ArrayLen（ApiData）＃指数=我＆GT CFLOOP;
      ＆LT; CFLOOP从=1=＃ColumnLength＃指数=我＆GT;
              ＆LT;！ - ＆LT; cfdump VAR =＃ApiData [1]。 +#ColumnNames [I]＃+＃＆GT; ---＆GT;
              ＆LT;！ - ＆LT; cfdump VAR =＃ApiData [I] .ColumnNames [I]＃＆GT;＆--- GT;
      ＆LT; / CFLOOP＆GT;
    ＆LT; / CFLOOP＆GT;
 

我不是一个ColdFusion的家伙，只是帮助好友和ColdFusion的语法与净很大的不同： - ）

感谢您的帮助。

解决方案

 ＆LT; CFLOOP从=1=＃arrayLen（ApiData）＃指数=我＆GT ;
  ＆LT; CFSET数据= ApiData [I]＆GT;
  ＆LT; CFLOOP集合=＃数据＃项=键＆GT;
    ＃键＃：＃数据[关键]＃
  ＆LT; / CFLOOP＆GT;
＆LT; / CFLOOP＆GT;
 

或者可以使用CFSCRIPT，这应该是很容易回升。

 为（D IN ApiData）// for-in循环数组
{
  对（在D键）// for-in循环的结构
  {
     writeOutput（钥匙＆安培;：和D [关键]）;
  }
}

Giving the Array of Structure below:

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

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>

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

Thank you for your help

解决方案

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

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]);
  }
}
