There is no direct way to convert an ArrayList to javascript array, you can loop through the ArrayList and add each element to javascript array. try this

javascript:

var jsArray = [];
<%for(int i=0;i<arrayList.size();i++){%>
    jsArray.push("<%= arrayList.get(i)%>");
<%}%>

You need to use javascript array and create the array using values from the server

var myArray=new Array("Value1","Value2","Value3");//condensed array
var myArray=["Value1","Value2","Value3"];//literal array

You can also use the JSON format to get the literal from the server.
