associative array with two strings

Question

is it possible to loop a simple array with key and value with a string in the [key] part ?

#!/bin/bash -x

wget url://stringlist1
wget url://stringlist2

#cat/sed some stuff ....

declare -A targetarray

loop $resultfromstringlist1
in strlistarray1 # filled with ( aka1 kaka hu3hu blabla )

loop $resultfromstringlist2
in strlistarray2 # filled with ( Thoralf Mirkoslav Pjotr Jan )

i=0;
for e in strlistarray1
do
   targetarray[$e]="${strlistarray2[$i]}"
   ((++i))
done

#wanted output 
echo ${targetarray[aka1]}  -> Thoralf

exit

i hope now is more clear

$e stays on $e its not filled with the string from strlist1 array

with manual setting works but not with loop bash version is 4.3

#!/bin/bash

unset aaaa
declare -A aaaa

str1="hans"
str2="klaus"

aaaa[$str1]="online";
aaaa[$str2]="offline";

echo ${aaaa[$str1]}

This demonstrates how to populate and query an associative array targetarray with keys and values from two simple arrays strlistarray1 and strlistarray2:

#!/bin/bash

declare -a strlistarray1=( aka1 kaka hu3hu blabla )
declare -a strlistarray2=( Thoralf Mirkoslav Pjotr Jan )

declare -A targetarray

i=0
for e in "${strlistarray1[@]}"; do
    targetarray["$e"]="${strlistarray2[i]}";
    ((i++))
done

for e in "${!targetarray[@]}"; do 
    echo $e --- ${targetarray[$e]}
done

To fetch the contents of a file (assuming one entry per line), try

IFS=$'\n'
declare -a strlistarray1=($(< yourfile))
unset IFS

To fetch data from a URL, try

IFS=$'\n'
declare -a strlistarray1=($(wget -qO - 'http://yoururl'))
unset IFS

(Setting IFS is required to avoid problems with fetched data containing spaces. If you're sure your input data doesn't have spaces, as in your question, the two IFS statements can be omitted.)
