推荐答案

function filladult(nopersons)
    {

    alert("you are here :" + nopersons);
     document.getElementById(<%=txtadult.ClientID%>).value= nopersons;
    }

function filladult(nopersons)
    {

    alert("you are here :" + nopersons);
     document.getElementById(<%= txtadult.ClientID %>).value= nopersons;
    }

或

or

function filladult(nopersons)
    {

    alert("you are here :" + nopersons);

（＃txtadult） .val（）= nopersons;
}

("#txtadult").val()= nopersons; }
