do not open the modal box by giving a node data-target ='- sharpModal10'
in the following way 

if(input){    // 
 $('-sharpModal10').modal('show');
}

$('- sharpModal10'). Modal ('hide');

show.bs.modal : This event fires immediately when the show instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the event.

the show.bs.modal event is triggered before the modal is displayed, so try blocking the event e.preventDefault (); or calling $('- sharpModal10'). Modal ('hide');

$('- sharpModal10'). On ('show.bs.modal', function (e) {

)

/ / $('- sharpModal10'). Modal ('hide'); 

or

/ / e.preventDefault ();

}) 

//
function addYZ(){
            var number = $("-sharpnumber").val();
            if(number == "" || number.replace(/\s*/g, "") == "") {
                alert("");
                $("-sharpbtn_upload8").attr("disabled", "disabled")
            } else {
                $("-sharpbtn_upload8").removeAttr("disabled")
                }              
            names=$("-sharpyzName").html();
            var data={
                        id:id,
                        name:names
               }                         
                };
        //        
                $("-sharpnumber").change(function() {
                    var number = $("-sharpnumber").val();
                    if(number == "" || number.replace(/\s*/g, "") == "") {
