错误：FORM中未定义元素HIDETXT。请告诉我如何纠正这个

当我单击第一个名称的单元格时，我需要对名字进行排序。我得到这个错误如何获取“form.hidetxt”值。此页面名称为“display_report.cfm”

Answer 1

#HIDETXT的值为空，因为

<input type="hidden" name="hidetxt" *value=""* id="hidetxt">

默认为空且

loadval()

不会设置此值..此外

function fnsort(firstname)
{
            alert("hi")
            alert(  $('#hidetxt').val().length); // #hidetxt is nul
            if($('#hidetxt').val().length ==0 )
            {
                $("#hidetxt").val("firstname Asc"); // here #hidetxt have to be "firstname Asc"
               // alert(    $('#hidetxt').val()); 
               loadval();
               alert("asc function")

            }
            else
            {
                var str="firstname Asc";
                var n=str.split(" ");
                if(n[0] == "firstname")
                {
                    $("#hidetxt").val("firstname Desc"); // here #hidetxt has to be "firstname Desc"
                    alert("desc function") // fix ;
                    $('#hidetxt').val("") // fix ; and #hidetxt will be ""
                }   
                else
                {
                    alert("Control is wrong")
                }
            }
        /*document.getElementById('form2').action="display_report.cfm"; 
            document.getElementById('form2').submit();  */
}

我认为你必须

console.log($('#hidetxt')

测试是否找到该元素..

之后尝试通过运行方法来使用值来启动它..

如何从同一页面获取隐藏值
