如何在冷聚变中最好地从多维数组中查找和删除元素

Question

我正在尝试根据搜索字符串从 coldfusion 中的多维数组中删除一个元素(当位置 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，它有效(此处数组中的第二个元素被删除(，但它出错了，因为它弄乱了索引 - 当数组长度为 n-1 时，它会尝试检查第 n 个元素删除后。

<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

更改以下内容：

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

对此：

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

Answer 2

如果您是 ACF10+，而不是显式循环，您可以这样做：

<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：或者更好的是，没有循环。仍然是ACF10+，但也在Lucee工作。

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