I think without seeing your array example, you mean splitting the data in the array into two lists?
<cfset selectList1 = listAppend(selectList1, listFirst(i,':')) >
<cfset selectList2 = listAppend(selectList2, listLast(i,':')) >
Frage
Can I split an array into two separated ones with each element in the original array separated by a ":"? The text before the ":" goes to array1, the text after ":" goes to array2
<cfset tempArr = DeserializeJSON(URL.data) />
<cfset selectList = "" />
<cfloop array=#tempArr# index="i">
<cfset selectList = listappend(selectList,i) />
</cfloop>
Right now this code grabs the whole element and not separately.
Edit
A sample string would be:
first_name:Bob
first_name goes into selectList1 Bob goes into selectList2
The grand scheme of things would have other fields likewise:
first_name:Bob
last_name:Shmo
age:27
etc...
EDIT: Answer
Problem was solved by using the code
<!---Variables--->
<cfset temp1 = "" />
<cfset temp2 = "" />
<cfset selectList1 = "" /><!---Holds column names for tables--->
<cfset selectList2 = "" /><!---Holds query parameters for column names. Ie,
values for use in the WHERE clause--->
<cfloop array=#tempArr# index="i"><!---Loop through contents of the array--->
<cfset temp1 = GetToken(i,1,":")/><!---Store the column name--->
<cfset temp2 = GetToken(i,2,":")/><!---Query parameter--->
<cfset selectList1 = listAppend(selectList1, temp1)/><!---Adds to list of column names--->
<cfset selectList2 = listAppend(selectList2, temp2)/><!---Adds to the list of query parameters--->
</cfloop>

why not convert the array in a list
<cfset list = arraytolist(array,",")>
and then use regex for getting the first chunk of elements, e.g. half the len of the array or whatever you like chunk size.
<cfset chunksize = int(listlen(list)/2)+1>
and then do a new array with a listpart (chunK) in each element:
<cfscript>
function ListSplit(list, chunkysize, delim)
{
var result = ArrayNew(1);
var re = "";
var start = 1;
while(1) {
re = REFind("((?:[^#delim#]+#delim#){1,#chunkysize#})", list & delim, start, "true");
if( re.len[1] eq 0 ) break;
ArrayAppend(result, Mid(list,re.pos[1],re.len[1]-len(delim)));
start = re.pos[1] + re.len[1];
if(start gte len(list)) break;
}
return result;
}
</cfscript>
<cfset newarray = ListSplit(list, chunksize, ",")>
e.g. list is 1,2,3,5,10,11,22,33,44,55,60,61,62,63,64 and you want split the list in 2 chunks then chunksize will be 8 the array will be result[1] = "1,2,3,5,10,11,22,33" result[2] = "44,55,60,61,62,63,64"
or get 3 chunks with gives you result[1] = "1,2,3,5,10" result[2] = "11,22,33,44,55" result[3] = "60,61,62,63,64"
etc.
I found the script from Nathan Youngman https://gist.github.com/nathany/742242 its very useful for dividing long lists or array in chunks of a given size
