                var qjNum=$(“input[@name=qjNum]”).val();
                var toAscii=qjNum.charCodeAt();
                if(toAscii > 65295 && toAscii < 65306 && qjNum.length == 11)
                {
                    var toBack = 0;
                    var temp = 0;
                    var unite = “”;
                    for(var i=0;i < qjNum.length;i++)
                    {
                        toAscii=qjNum.charCodeAt(i);
                        toBack =toAscii-65248;
                        temp = String.fromCharCode(toBack);
                        unite = unite + temp ;
                    }
                    alert(unite);
