query string help

[Navarone]

I am having trouble with query strings. In my menu I have a simple anchor tag


<a href="learn_more.aspx?isOn=2&isAt=2"><div class="learn_more" id="ab2"></div></a>


When I click on this link, the code should switch the class but it is not getting into my else if (qsParm['isOn']==2 && qsParm['isAt']==2) statement.

I don't know why it's not working. Any help greatly appreciated.


<!--this java script code checks the isOn state and switches the class to an selected sate-->

<script type="text/javascript">
var qsParm = new Array();
function qs() {
var query = window.location.search.substring(1);
var parms = query.split('&');
for (var i=0; i<parms.length; i++) {
var pos = parms[i].indexOf('=');
if (pos > 0) {
var key = parms[i].substring(0,pos);
var val = parms[i].substring(pos+1);
qsParm[key] = val;
}
}
}


qsParm['isOn'] = null;
qsParm['isAt'] = null;

qs();


if (qsParm['isOn']==2){
document.getElementById('ab2').className="learn_more_selected";

}else if (qsParm['isOn']==2 && qsParm['isAt']==2){
document.write('You selected ' + qsParm['isOn'] + qsParm['isAt'])
document.getElementById('ab2').className="learn_more_selected";
document.getElementById('Lm1').className="what_hemorrhoid_selected";

}else if (qsParm['isOn']==2 && qsParm['isAt']==3){
document.getElementById('ab2').className="learn_more_selected";
document.getElementById('Lm2').className="treatment_procedure_selected";

}else if (qsParm['isOn']==3){
document.getElementById('ab3').className="about_us_selected";

} else if (qsParm['isOn']==4){
document.getElementById('ab4').className="gutman_selected";

} else if (qsParm['isOn']==5){
document.getElementById('ab5').className="contact_selected";

}else {
document.getElementById('ab2').className="learn_more";
document.getElementById('ab3').className="about_us";
document.getElementById('ab4').className="gutman";
document.getElementById('ab5').className="contact";

document.getElementById('Lm1').className="what_hemorrhoid";
document.getElementById('Lm2').className="treatment_procedure";
}

</script>

I think I found my own solution. I am not exactly sure why but my isAt value needed to be a number instead of a string. ie, isAt=Lm1 (no go) but isAt=2, OK. Go figure!
