JSON string not returned properly in JSP

String json1 = new Gson().toJson(list);
System.out.println(json1);
request.getSession().setAttribute("json1", json1);

I checked the logs it prints string like : ["090856","056986"]

In JSP I wrote something line below in script 

var n = '<%= session.getAttribute("json1") %>';
alert(n);

The alert displayed 090856,056986.

why such behaviour should not it display ["090856","056986"].

sometimes it also appears like this too

There is nothing wrong in your your code. alert is modifying the string while showing.

  1. Use console.log(n) to test your json string.

  2. Or use JSON.stringify function 

    alert(JSON.stringify(n));

It's normal behaviour.

You can try directly in chrome console.

  1. List item
  2. Go to chrome
  3. Press F12
  4. Go to Console tab
  5. Enter command : alert( ["090856","056986"]);
  6. As a result you have the following alert box
