Question

我正在尝试获取控件的值，如下所示：

 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; }
        }

并且CONFIRM框根本没有开火！我没有弹出任何东西。

我尝试使用firefox进行调试，并且一旦进入此行：

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

它逃脱了函数

我在做错了什么？我怎样才能获得所有控件的值？

Answer 1

您需要为value使用小写“v”并引用您的元素ID。例如：

document.getElementById("received_dateTextbox").value

由于您似乎已经在使用jQuery，因此您可以使代码更简洁。所以document.getElementById("received_dateTextbox").value变为：

$("#received_dateTextbox").val()

Answer 2

没有名为spec_idTextBox的变量您可能想要传递一个字符串文字。

修复后，您需要使用小写的.value

Answer 3

如果您使用的是动态客户端ID，则必须内联呈现ID或将其传递给您的函数：

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