Question

我试图从基于搜索字符串的coldfusion中的多维数组中删除元素（位置1与我的搜索字符串匹配时的完整数组）。我想出了以下内容，它可以工作（此处数组中的第二个元素被删除），但是它出错了，因为它弄乱了索引 - 当数组的长度为n-1时，它会尝试检查第n个元素删除。

<cfset Profiles  =
[ 
    ["aaa",     "xdg",   "123",   "xyz",  "ggg"   ],
    ["bbb",     "xwa",   "234",   "xyz",  "fff"   ],
    ["ccc",     "xed",   "567",   "xyz",  "eee"   ],
    ["ddd",     "xae",   "789",   "xyz",  "hhh"   ],
    ["eee",     "xsr",   "901",   "xyz",  "bbb"   ],
    ["fff",     "xdg",   "902",   "xyz",  "jjj"   ]
]/>

<cfset CheckFor = "bbb" />
<cfset Position = 1 /> 
<cfloop array="#Profiles#" index="arrayIndex"   >

    ArrayFind: #arrayFind( arrayIndex, CheckFor  )#<br />

    <cfif #arrayFind( arrayIndex, CheckFor  )# eq 1 > 
        #arrayDeleteAt( Profiles, Position )#
    </cfif>

    <cfset Position++ /> 

</cfloop>

<cfdump var="#DocumentProfiles#" />

Answer 1

改变这个：

  <cfif #arrayFind( arrayIndex, CheckFor  )# eq 1 > 
        #arrayDeleteAt( Profiles, Position )#
    </cfif>

    <cfset Position++ />

到此：

<cfif #arrayFind( arrayIndex, CheckFor  )# eq 1 > 
        #arrayDeleteAt( Profiles, Position )#
<cfelse>
    <cfset Position++ /> 
</cfif>

如果你是ACF10 +，而不是显式循环，你可以这样做：

<cfscript>

Profiles = [
    ["aaa","bbb","asdf"]
  , ["bbb","asdf","asdfasfs"]
  , ["ccc","dfhgasdfg","bbb"]
  , ["bbb","asdfasdf","Aasdfa"]
] ;

checkfor = "bbb" ;

//// FROM HERE ////    
arrayEach(
  Profiles,
  function(obj){
    obj[1]==checkfor?arrayDelete(Profiles,obj):'';
  }
);
//// TO HERE ////

WriteDump(Profiles);

</cfscript>

编辑：或者更好，没有循环。仍然是ACF10 +，但也适用于Lucee。

p2 = arrayFilter( Profiles, function(obj){ return obj[1] != checkfor ; } );

如何最好地从coldfusion
