How can I disable the div using jquery before button submit ?

How can I disable the div using jquery before button submit ?

I have two divs called "Yes" and "No"

<div id="object">
    <div class="object-content">
        I'd say
        <div class="confirm" id="btnYes" runat ="server" >Yes</div>
    </div>
    <div class="object-content" style="float: right">
        I'd say
        <div class="confirm" style="color: red"  id="btnNo" runat="server">No</div>
    </div>
</div>


And one Comment button called "Post"


<asp:Button ID="btnPostUrComment" OnClick="btnPostUrComment_Click" runat="server" Text="Post Your Comment" Height="33px" class="ppig" />


When I directly click on the "Post" I alert "Please select Yes or NO by clicking on them"
And click on the "yes" or "no" div I alert "You said "Yes" or "no" "

Now the problem is , after all this If I click "yes" div then the "no" div will be disable not hide before click on "Post" button and vice versa . 

I am trying some script. Please guide me.


<script>
$(document).ready(function () {
    var IsPostComment = false;
    var clickedElement = "";

    $('.confirm').click(function () {
        IsPostComment = true;
        clickedElement = $(this).text();
    });

    $('#<%=btnPostUrComment.ClientID %>').click(function () {
        if (IsPostComment) {
            alert("You Said " + clickedElement);
            
        } else {
            alert("Please select Yes or NO by clicking on them")
            return false;
        }
    });
});
</script>
