$.ajax({
                   type:"POST",
                   async:false,
                   contentType:"application/x-www-form-urlencoded",
                   url:"http://localhost/Test/Service/ServiceForJquery.asmx/HelloWorld",
                   data:"{str:'hahaha'}",
                   dataType:'json',
                   success:successFunction，
                   error:errorFunction

                });

});

改为：

$("#Button1").click(function(){
                typeValue=$("#Text1").val();
                $.ajax({
                   type:"POST",
                   async:false,
                   contentType:"application/x-www-form-urlencoded",
                   url:"http://localhost/Test/Service/ServiceForJquery.asmx/HelloWorld",
                   data:{str:'hahaha'},
                   dataType:'json',
                   success:successFunction，
                   error:errorFunction

                });
});
