Question

In javascript i am building up a string like this…

var txt = "{authenticationToken: 1, authenticated: 2, authenticationTokenExpiry: 3,sessionTimeoutMinutes: 4,userName: " + userName + "}";

This is later put through and eval statement like this…

var obj = eval('(' + txt + ')');

When this happenings I get a reference error saying the the value of the username variable is undefined.

Does anyone know the reason for this? Is it something simple that I am missing?

Your missing quotes around the username variable:

var txt = "{authenticationToken: 1, authenticated: 2, authenticationTokenExpiry: 3,sessionTimeoutMinutes: 4,userName: '" + userName + "'}";

I assume you want to store the string value of the username in your userName variable. Since it wasn’t quoted it was treating the value of username as a variable. So for example if username was “testValue123” it would of been userName: testValue123 instead of userName: 'testValue123'
