I am trying to passe an array from ejs to JavaScript. I can get to the values inside ejs but not from JavaScript. all the time i get undefined because the contents of the variable test is a string is not an array.

<script>



var test = '<%- level_tab %>';

alert(test);



function level(s1,s2){

            var s1 = document.getElementById(s1);

            var s2 = document.getElementById(s2);

            s2.innerHTML = ;

            if(s1.value == level_0){

                var optionArray = test;

            }

            else if(s1.value == level_1){

                var optionArray = [test|test01, test0|test02];

            }

 for(var option in optionArray){

                var pair = optionArray[option].split(|);

                var newOption = document.createElement(option);

                newOption.value = pair[0];

                newOption.innerHTML = pair[1];

                s2.options.add(newOption);

            }

        }

</script>
