Question

此处的情况是我已将dynamic row添加到包含tds为textbox和span标记的表格中，

现在我在演示中做一些计算，你会看到一个多因素文本框，在更改时会将我的表更新到最后一列，即（提供的计算区域），

我遇到的问题是我需要获取最后一列（四轮车）的更新计算值，我能够更新跨度但不能更新文本框

JS代码：

$("#apnd_tr").on('click',function(){
$(".Total_result").parents('tr').before(row_1cnt);
    $(".Total_result").parents('tr').before(row_2cnt);
});



var arrParkingRowIds = new Array();
        $("#myMultipleFactor").on('input', function () {

            var get_factorValue = $(this).val();
            var counter = 0;
            $("#myTable [class*=id_]").each(function () {
                counter++;
                if (counter == 4) {
                    var da = $(this).attr('class');
                    var fourWhlrValue = $("." + da).find("#txtprovidedNoParfetch").val();
                    var setResultProvidedParking = Number(fourWhlrValue) * Number(get_factorValue);
                    $("." + da).find("#txtprovidedPAfetch").next().html(setResultProvidedParking.toFixed(2));
                    $("." + da).find("#txtprovidedPAfetch").val(setResultProvidedParking);
                    counter = 0;
                    arrParkingRowIds.push(da);
                }
            });
        });

        $("#mValue").on('click', function () {
            for (var i = 0; i < arrParkingRowIds.length; i++) {
                var gData = arrParkingRowIds[i];
                alert($("." + gData).find('td:eq(7)').html());
            }
        });

在一些R＆amp; d之后我发现了导致问题的原因..它的文本输入html是display：none和一些禁用的地方，它没有得到更新或者不能保持可编辑（可能是jquery bug）。

Fiddle demo

有两种方法可以解决它..

快速简便的解决方法是使用element.attr("value" , "yourvalue")而不是element.val()。
将类型文本更改为隐藏的替代修复方法（所有方法仅将其设置为例如。）

 <input type="text" value="2323232323" tabindex="1" style="margin-bottom: 0px; width: 80% ! important; display: none;" id="TextTitleFetch" class="prk_txt_style" />

<input type="hidden" value="2323232323" tabindex="1"  id="TextTitleFetch" class="prk_txt_style" />

据我所知，这些输入主要用于表单数据或内部使用，因此您可以将它们保留为隐藏类型。

更新了输入demo

设置动态添加的文本框值在Jquery中具有display：none属性
