Get JSON specific value using jQuery

Question

I have a json which is generated through php and i assigned it to a JS variable like below,

var jsonObj =  {
    "ATF":["FLV"],
    "Limecase":["FLV"],
    "RCF":["FLV","HTTP","PALM","MOBILE","3GP","H263","F263","WMV"],
    "Wave":["FLV","IPHONE","MOBILE"]
}

And also i have a selectbox in html as below,

<select id="selectbox" data-rel="chosen"> 
    <option value='ATF'>ATF</option>
    <option value='Limespace'>Limespace</option>
    <option value='RCF'>RCF</option>
    <option value='Wave'>Wave</option>
</select>

On changing, i am getting the selected value and passing it as below,

alert(jsonObj.selVal); but alert throws "undefined"

But if i give direct value jsonObj.ATF, it gives FLV.

Please suggest me on this.

why it is throwing undefined?, if i try like jsonObj.selVal. – Raja Aug 30 '13 at 07:51
@Yadheendran Because it looks for a property "selVal". This does not exist. – Tobias Golbs Aug 30 '13 at 07:57
