对话框模式中的 Gridview onclick 与 asp.net 中的引导程序将值返回到模式父页面 webforms

Question

我整天都在尝试和搜索如何在模式弹出窗口内的网格视图中连续单击并将这些值返回到模式弹出窗口的“父亲”上的标签/文本框，我已经在使用 javascript打开和关闭模式。 return 可以放在 closeModal() 中。我只需要一个例子，我查看了很多论坛和页面，但没有找到这样的。谢谢你的帮助

这是 ASP.NET 代码

<script>
    function openModal() {
        $('#myModal').modal('show')
    };

    function closeModal() {
        console.log("Sai")
        $('#myModal').modal('hide')
        document.getElementById('<%= lblTeste.ClientID %>').innerHTML = 'Your new value';
        console.log("valor mudado")
    };

  function sendTex(texto) {
        document.getElementById('<%= txtExample.ClientID %>') = texto;
    }
</script>

<asp:Label id="lblSelected" runat="server"></asp:Label>

<div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">
    <!-- Modal content-->
        <div class="modal-content" runat="server">
            <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title">Modal Header</h4>
            </div>
            <div class="modal-body">
                <asp:TextBox ID="txtBusca" runat="server"></asp:TextBox>
                <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                    <ContentTemplate>
                        <asp:GridView ID="gvBusca"  OnRowDataBound="OnRowDataBound"
                        OnSelectedIndexChanged="OnSelectedIndexChanged" DataKeyNames="id" 
                        runat="server" GridLines="Horizontal" 
                        BorderStyle="None" CssClass="table table-striped table-hover ">
                        </asp:GridView>
                        <asp:Button ID="btnBusca" runat="server" Text="Button" />
                        <asp:Label id="lblValor" runat="server" Text=""></asp:Label>
                    </ContentTemplate>                       
                </asp:UpdatePanel>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" onclick="closeModal()">Close</button>
            </div>

        </div>
    </div>
</div>

这是后面的代码：

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs) Handles gvBusca.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        e.Row.Attributes("onclick") = Page.ClientScript.GetPostBackClientHyperlink(gvBusca, "Select$" & e.Row.RowIndex)
        e.Row.Attributes("style") = "cursor:pointer"
    End If
End Sub


Protected Sub OnSelectedIndexChanged(sender As Object, e As EventArgs) Handles gvBusca.SelectedIndexChanged
    Dim index As Integer = gvBusca.SelectedRow.RowIndex
    Dim name As String = gvBusca.SelectedRow.Cells(0).Text
    Dim country As String = gvBusca.SelectedRow.Cells(1).Text
    Dim message As String = "Row Index: " & index & "\nName: " & name + "\nCountry: " & country
    ClientScript.RegisterStartupScript(Page.GetType(), "Desc", "sendText('" + name + "');", True)
End Sub

Answer 1

document.getElementById('<%= txtExample.ClientID %>').value = texto;

我想你忘了在上面的声明中添加.value。
