Question

我已经花了整整一天的时间，已经阅读了有关该主题的几乎所有帖子，但仍然无法正常工作。我正在尝试使用js / ajax从asp.net中的javascript弹出窗口中的文本框（最好是复选框，但从文本框开始进行测试）捕获值，如下所示：

在Site.Master中：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.6/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>

HTML：

<script type="text/javascript">
    function openprojectCopyModal() {
        $("#projectCopyModal").modal('show');
    }
    function btnCopyConfirmClick() {
            $.ajax({
                url: "Member/ModalDetails",
                type: 'GET',
                contentType: "application/json; charset=utf-8",
                dataType: 'json',
                data: JSON.stringify({
                    txtTest: $("#txtTest").val()
                }),
                success: function (response) {
                    //
                },
                error: function (XMLHttpRequest, textStatus, errorThrown) {
                    //
                }
            });
        };      
</script> 

    <!--Modal Save confirmation-->
<div class="modal" id="projectCopyModal">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Copy Project Confirmation</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <p>Please select optional items to include when copying this project:</p>
            <div style="float: left;">
       <asp:TextBox ID="txtTest" CssClass="form-control" Width="250px" runat="server" />
            </div>
      </div>
      <div class="modal-footer">            
        <button id="btnCopyConfirm" type="button" class="btn btn-primary" onclick="btnCopyConfirmClick">Save</button>
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
      </div>
    </div>
  </div>
</div>

CodeBehind：

// Make a copy of project
protected void btnCopy_Click(object sender, EventArgs e)
{
    // Get ID of project to copy
    ListViewItem item = (sender as ImageButton).NamingContainer as ListViewItem;
    int iID_orig = Convert.ToInt16(ListView_Project.DataKeys[item.DataItemIndex].Values["ProjectID"]);
    this.Session["copyID"] = iID_orig;

    // Prompt to verify
    ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "openprojectCopyModal();", true);

}
    [WebMethod]
    [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
    public static string ModalDetails(string txtTest)
    {
        return txtTest;
    }

它将弹出对话框，仅此而已，它不会调用位于我的项目根文件夹Members中的WebMethod'ModalDetails'（已经尝试了'url'“〜/ Members / Member / ModalDetails”及其多次迭代谢谢

编辑： 我将功能更新为仍然无效：

$(function () {
            $('[id*=btnCopyConfirm]').click(function () {
                $.ajax({
                    url: "Member/ModalDetails",
                    type: 'POST',
                    contentType: "application/json; charset=utf-8",
                    dataType: 'json',
                    data: JSON.stringify({
                        txtTest: $("#txtTest").val()
                    }),
                    success: function (response) {
                        //
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                        //
                    }
                });
            });
        });

更新无论出于什么原因，我都无法使它正常工作，因此我针对那些可能有帮助的人，将其与jquery结合使用了asp按钮服务器端：

jquery：

function storevalue() {
        var str = $("#txtTest").val(); 
        alert(str);
        if (str=="") {
            return false;
        }
        else {
            document.getElementById("hfCopyOptions").value = str;
            return true;
        }

    }

html：

<asp:Button ID="btnCopyConfirm" runat="server" CssClass="btn btn-primary"  Text="Copy" OnClick="btnCopyConfirm_Click" OnClientClick="return storevalue();" />

在更新后的帖子的更新下使用了解决方案。

使用jquery / asp.net的ajax对话框中的值
