如何在中继器中用组名设置3单选按钮

repeater radio-button asp.net c#

Kenzo_Gilead · 技术社区 · 6 年前

我最好的方法是:

<asp:Repeater runat="server" ID="repeaterImages" OnItemDataBound="repeaterImages_ItemDataBound">
  <ItemTemplate>
    <span>
          <asp:RadioButton runat="server" ID="rbLogoSeleccionado" Text='Logo 0' GroupName="nombreLogo" /><br />
          <asp:RadioButton runat="server" ID="rbLogoSeleccionadoApp" Text='Logo 1' GroupName="nombreLogoApp" /><br />
          <asp:RadioButton runat="server" ID="rbLogoSeleccionadoAppBlanco" Text='Logo 2' GroupName="nombreLogoAppBlanco" />
   </span>
 </ItemTemplate>
</asp:Repeater>

JS公司

<script>
    function SetUniqueRadioButton(nameregex, current) {

        for (i = 0; i < document.forms[0].elements.length; i++) {

            elm = document.forms[0].elements[i]

            if (elm.type == 'radio') {

                elm.checked = false;
            }
        }
        current.checked = true;
    }
</script>

protected void repeaterImages_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    try
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            RadioButton rbLogoSeleccionado = (RadioButton)e.Item.FindControl("rbLogoSeleccionado");
            RadioButton rbLogoSeleccionadoApp = (RadioButton)e.Item.FindControl("rbLogoSeleccionadoApp");
            RadioButton rbLogoSeleccionadoAppBlanco = (RadioButton)e.Item.FindControl("rbLogoSeleccionadoAppBlanco");

            string script = "SetUniqueRadioButton('repeaterImages.*nombreLogo',this)";
            string scriptApp = "SetUniqueRadioButton('repeaterImages.*nombreLogoApp',this)";
            string scriptAppBlanco = "SetUniqueRadioButton('repeaterImages.*nombreLogoAppBlanco',this)";

            rbLogoSeleccionado.Attributes.Add("onclick", script);
            rbLogoSeleccionadoApp.Attributes.Add("onclick", scriptApp);
            rbLogoSeleccionadoAppBlanco.Attributes.Add("onclick", scriptAppBlanco);
        }
    }

    catch (Exception ex)
    {
        PIPEvo.Log.Log.RegistrarError(ex);
        throw;
    }
}

小菜一碟。证明我在JS有多新。我张贴的解决方案,因为是一个经常性的问题,在asp编程和这个错误是已知的。除此之外,我找不到解决某些单选按钮。

<script>
    function SetUniqueRadioButton(text, current) {
        for (i = 0; i < document.forms[0].elements.length; i++) {

            elm = document.forms[0].elements[i]

            if ((elm.type == 'radio') && (elm.value == text)) {
                elm.checked = false;
            }
        }
        current.checked = true;
    }
</script>
