So, storing a Java String into a form hidden input value. I call said value via javascript and attempt to store it into a var. Strangely, I can display the value via alert but javascript crashes when I try to save it into a var.

The first line is from the initializing jsp file. It does some stuff that gets the string. The string is a list of ints that I plan on splitting in javascript for some stuff.

"<form id = \"listArrForm\"> <input id = \"listArr\" value = "+ output +" type = \"hidden\"></form>"

var listArr = document.getElementById("listArr").value; //Does work

alert(document.getElementById("listArr").value); //Does work

So yea, I’m guessing it has to do with the the type of value being retrieved?

    Well, both should work as you can see in this jsfiddle: http://jsfiddle.net/2eWja/

    What are you storing in the value that makes the script not work? Are you sure you’re not putting quotes in?
