while-loop problem

Question

Hey Guys, I have a problem with the following code:
var x = document.getElementById('Auswahl').value;
var activeElements = document.querySelectorAll('#class1').length;
while(activeElements < x){
document.getElementsByClassName("wrapper")[0].appendChild(cln);
activeElements = document.querySelectorAll('#class1').length;
if(activeElements == x){
break;
}
}
In this loop my input is 3. The loop should run until i have 3 Elements named #class1. But the loop never stops. It works with the input 2 but not with 3 or 4. Can anybody help me out?

Answer 1

@Rithea Sreng after some debbuging i found out that this line "document.getElementsByClassName("wrapper")[0].appendChild(cln);" is only executet 1 time, After that this line does not work anymore. at the beginning i have tried it with activeElements++ but it didn't work.

Answer 2

NVM I found the problem

Answer 3

How did you solve it?

Answer 4

document.getElementsByClassName("wrapper")[0].appendChild(cln);
This line is like Strg+V but only works one time. So i put two code lines (which are not included in the code above) into the while loop and then i could copy it infinite times.
