Question

I can better explain it with Raw script.

<script>
    $(document).ready(function () {
        $("Div").  //lock div here

        var condition=$("#value").val();
        if(condition==true){unlock div here}
        else{do nothing}
    });
</script>

Is there any jquery widget i have to include?

By saying lock/unlock I mean Enable/Disable.

Answer 1

<script>
    $(document).ready(function () {
        $("Div").attr('disabled','true');  //lock div here


        var condition=$("#value").val();
        if(condition==true)
              $("Div").attr('disabled','false');//{unlock div here}
        else{do nothing}
    });
</script>
