How to disable current Date Picker's Calender icon using JQuery

[Rajneesh]

Hi,
I have three radio buttons and three Date Picker's based on that i want to enable and disable Calender Icon to prevent selection.
I was able to make dtp read only and Calender Image hide when it was only one place but now if i use show/hide Calender image its reflecting for all three Date Picker's.
See code:

function toggleInput(selectedCondition) {
        if (selectedCondition == "byDays") {
            $("#txtDays").removeAttr("readonly");
            $("#dtpDateRange").attr("readonly", "true");
            $("#dtpFromDate").attr("readonly", "true");
            $("#dtpToDate").attr("readonly", "true");
            $(".t-icon-calendar").hide();
            $("#dtpDateRange").val("");
            $("#dtpFromDate").val("");
            $("#dtpToDate").val("");
        }
        else if (selectedCondition == "byDateRange") {
            $("#dtpDateRange").attr("readonly", "true");
            $("#dtpDateRange").val("");
            $("#dtpFromDate").removeAttr("readonly");
            $("#dtpToDate").removeAttr("readonly");
            $("#txtDays").attr("readonly", "true");
            $(".t-icon-calendar").show();
            $("#txtDays").val("0");
        }
        else {
            $("#dtpDateRange").removeAttr("readonly");
            $("#dtpFromDate").attr("readonly", "true");
            $("#dtpFromDate").val("");
            $("#dtpToDate").attr("readonly", "true");
            $("#dtpToDate").val("");
            $("#txtDays").attr("readonly", "true");
            $(".t-icon-calendar").show();
            $("#txtDays").val("0");
        }
    }

What i want now is, Either i am able to Show/Hide Calender Image for associated Date Picker's or i am able to enable/disable perticular Date Picker control using JQuery.
Hope i am able to justify my question. See the attached image.
