how can assemble var in javascript during runtime without eval?

var lc = $('.bezeichnung-1').length; (var lt = 1; lt <= lc; lt++) {     eval("var neuerwert"+lt+"=0;"); // works don't want use because read eval bad }   var lc = $('.bezeichnung-1').length; (var lt = 1; lt <= lc; lt++) {     window["var neuerwert"+lt] = 0; // not work }

you don't, can make property of something.

if these @ global scope, they're properties:

var lc = $('.bezeichnung-1').length; (var lt = 1; lt <= lc; lt++) {     window["neuerwert"+lt] = 0;     // -----^ no `var` keyword } 

if they're not @ global scope (good you!), make them properties of object, e.g.:

var neuerwert = {     1: /*...value here...*/,     2: /*....value here...*/ }; 

or array

var neuerwert = [     /*...value here...*/,     /*....value here...*/ ]; 

and then

var lc = $('.bezeichnung-1').length; (var lt = 1; lt <= lc; lt++) {     neuerwert[lt] = 0; } 

note array indexes start @ 0, may have adjust lt if you're using array.
