DefaultButton不支持将该属性与LinkButton. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.panel.defaultbutton.aspx

最简单的解决方案是在页面上包含一个虚拟按钮style="display:none"，将其设置为默认按钮，并为其提供与 LinkBut​​ton 相同的事件处理程序。

I had this kind of issue with FF3 and ASP.NET linkbuttons. This seems to be a bug with FF3 (not sure), but the script that fixed is given below:

var __defaultFired = false;

function WebForm_FireDefaultButton(event, target) {
    var element = event.target || event.srcElement;

    if (!__defaultFired && event.keyCode == 13 && !(element && (element.tagName.toLowerCase() == "textarea"))) {
        var defaultButton;

        if (__nonMSDOMBrowser)
            defaultButton = document.getElementById(target);
        else
            defaultButton = document.all[target];

        if (defaultButton) {
            if(typeof(defaultButton.click) != "undefined")
                defaultButton.click();
            else
                eval(unescape(defaultButton.href.replace("javascript:", "")));

            event.cancelBubble = true;

            if (event.stopPropagation) event.stopPropagation();
            return false;
        }
    }
    return true;
}

Keep it at the end of the page so that it overrides the WebForm_FireDefaultButton method rendered by ASP.NET.

我的第一篇 Stack Overflow 写的，哇 :-)

ASP.NET：

<asp:Panel runat="server" DefaultButton="lbHello">
    First name: <asp:TextBox runat="server" ID="txtFirstName" />
    <asp:LinkButton ID="lbHello" Cssclass="button" runat="server" Text="Click me" OnClick="lbHello_Click" />
</asp:Panel>

js：

$(document).ready(function () { $('.button').eventClick(); });

$.fn.eventClick = function() {
    function eventClick(a) { 
            if (a && typeof (a.click) == 'undefined') {
                a.click = function () {
                    var result = true;
                    if (a.onclick) result = a.onclick();
                    if (typeof (result) == 'undefined' || result) {
                        eval(a.getAttribute('href'));
                    }
                }
            }
        }
        return eventClick($(this).get(0));
}

我认为它非常简单，只需添加需要回发的文本框的 onkeypress js 事件。

txtUserName.Attributes.Add("onKeyPress", "javascript:if (event.keyCode == 13)
 __doPostBack('" + btnLogin.UniqueID + "','')");

希望这会有所帮助。

仅在我们第一次在文本框中按 Enter 时起作用。在文本框中添加一些文本然后按 enter 后，默认按钮将不会触发。
