As far as I know,
I wrote this code, İt worked in Firefox.
<script type="text/javascript">
var projects = [
{id: "t123",label: "Burger King",desc: "Burger King Dallas, TX 75233"},
{id: "t234",label: "Chic Fila",desc: "Chic Fila Chicago, IL 12255"},
{id: "t345",label: "Chipotle",desc: "Chipotle Terrell TX 85211"}
];
alert(projects[0].id); // t123
alert(projects.toSource());
projects[3] = { id: "t103", label:"The Time Through Ages", desc:"In the Name of Allah, Most Gracious, Most Merciful. 1. By the Time, 2. Verily Man is in loss, 3. Except such as have Faith, and do righteous deeds, and (join together) in the mutual enjoining of Truth, and of Patience and Constancy."};
alert(projects[3].id); // t103
alert(projects[3].label); // The Time Through Ages
alert(projects[3].desc); // In the Name of Allah, Most Gracious, Most Merciful. 1. By the Time, 2. Verily Man is in loss, 3. Except such as have Faith, and do righteous deeds, and (join together) in the mutual enjoining of Truth, and of Patience and Constancy.
