javascript中的验证在多个if else语句中不起作用

下面是我的javascript代码-每当单击代理单选按钮时，它会进入第一个验证部分，而不检查其他部分:

function validate(form1) 
    {
        var agent1=document.getElementById('agent');
        var confirm=document.getElementById('confirm');
        var holding=document.getElementById('holding');
        var confirm=form1.confirm.value;
        var book_by=form1.bookby.value;
        var bkother=form1.bookbyother.value;
        var agntphn=form1.phone1.value;
        var gstnam=form1.guest_name.value;
        var gstphn=form1.guest_no.value;
        var adlts=form1.no_adults.value;
        var children=form1.no_child.value;
        var infants=form1.no_infants.value;
        var check_in=form1.checkin.value;
        var check_out=form1.checkout.value;
        var nfd1=form1.no_of_days.value;
        var rc=form1.roomtype.value;
        var rpd=form1.rp_day.value;
        var rpb=form1.extrarate.value;
        var tamt=form1.totalamount.value;
        var advamt=form1.advance_amount.value;
        if ((agent1.checked == true))
        {
            if(!(book_by || bkother))
            {
                alert('Choose the valid agent')
            }
            else if(agntphn =="")
            {
                alert('Enter the agent phone number')
            }
        }
        else if (gstnam=="") {
            alert("Enter a valid Name ");
            document.getElementById('guest_name').focus();
            return false;
            //errors[errors.length] = "Enter valid Name ";
        }
        else if (!ck_Mobileno.test(gstphn)) {
            alert("Enter a valid Mobile Number with 10 digits");
            document.getElementById('guest_no').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if ((adlts=="") &&( children=="" )&&( infants=="")) {
            alert("Enter a valid No of persons");
            document.getElementById('no_adults').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(check_in)) {
            alert("Enter a valid Checkin Date");
            document.getElementById('checkin').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(check_out)) {
            alert("Enter a valid  check_out date");
            document.getElementById('checkout').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(nfd1)) {
            alert("Click to the box to get the no of days");
            document.getElementById('no_of_days').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(rc)) {
            alert("Select the room type");
            document.getElementById('roomtype').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(rpd)) {
            alert("Enter the Rate Per Day");
            document.getElementById('rp_day').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(rpb)) {
            alert("Enter the Rate Per Bed");
            document.getElementById('extrarate').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(tamt)) {
            alert("Click on the box to get the total amount");
            document.getElementById('totalamount').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
        else if (!(advamt)) {
            alert("Enter the advance amount");
            document.getElementById('advance_amount').focus();
            return false;
            //errors[errors.length] = "Enter valid mobileno ";
        }
    }
</script>

检查jfiddle

一旦确认单选按钮被点击，所有禁用元素显示…
