c# - 获取所有控件的值

Question

我正在尝试像这样获取控件的值:

 function ConfirmWithUser() 
        {
            var nodeText = '';
            $('.mytreeview input[@type=checkbox]:checked').each(function() {
                nodeText += $(this).next('a').text() + '\r';


            });
            var confirmationMessage;
            confirmationMessage = "Please review the data before submitting:" + "\r"
            + "Sample Received Date: " + document.getElementById(received_dateTextbox).Value + "\r"
            + "Site of Ocurrence: " + document.getElementById(site_of_occurrenceTextBox).Value + "\r"
            + "Occurrence Date: " + document.getElementById(occurrence_dateTextBox).Value + "\r"
            + "Report Date: " + document.getElementById(report_byTextBox).Value + "\r"
            + "Specimen ID: " + document.getElementById(spec_idTextBox).Value + "\r"
            + "Batch ID: " + document.getElementById(batch_idTextBox).Value + "\r\n"
            + "Report Initiated By: " + document.getElementById(report_byTextBox).Value + "\r\n"
            + "Problem Identified By: " + $("input[@name=RadioButtonList1]:checked").val() + "\r\n"
            + "Problem List: " + nodeText;

            HiddenFieldConfirmation.Value = confirmationMessage;

            if (confirm(document.getElementById('HiddenFieldConfirmation').value) == true)
            { return true; }
            else
            { return false; }
        }

而且 CONFIRM 框根本没有触发!我没有得到任何弹出。

我尝试使用 firefox 进行调试，一旦它转到这一行:

confirmationMessage = "Please review the data before submitting:" + "\r"
                + "Sample Received Date: " + document.getElementById(re.......

它跳出函数

我做错了什么？如何获取所有控件的值？

Answer 1

您需要为 value 使用小写字母“v”并引用您的元素 ID。例如:

document.getElementById("received_dateTextbox").value

因为看起来您已经在使用 jQuery，所以您可以让您的代码更简洁一些。所以 document.getElementById("received_dateTextbox").value 变成:

$("#received_dateTextbox").val()
