You can do it using html5 data attributes like this:
您可以使用这样的 html5 数据属性来做到这一点：
<asp:LinkButton ID="lnkprogress" runat="server" class="label label-info" BackColor="#589FC2" data-bookingid='<%#Eval("BookingId")%>' CommandArgument='<%#Eval("BookingId")%>' OnClientClick="jk();" >In progress</asp:LinkButton>
Then retrieve it using some JavaScript like this:
然后使用一些 JavaScript 检索它，如下所示：
var lnkProgress = document.getElementById('<%= lnkProgress.ClientID %>');
var bookingID = lnkProgress.getAttribute("data-bookingid");
Although I'm assuming that your lnkProgress is going to be inside a naming container like one of the databound controls so it might not be as easy as getElementById('<%= lnkProgress.ClientID %>');to get a reference to it.
尽管我假设您的 lnkProgress 将位于一个命名容器内，如数据绑定控件之一，因此它可能不像getElementById('<%= lnkProgress.ClientID %>');获得对它的引用那么容易。

Add an html5 attribute as suggested by rtpHarry and send the control as a parameter in OnClientClick:
添加 rtpHarry 建议的 html5 属性，并将控件作为参数发送到 OnClientClick 中：
<asp:LinkButton ID="lnkprogress" runat="server" class="label label-info" `BackColor="#589FC2" data-bookingid='<%#Eval("BookingId")%>' CommandArgument='<%#Eval("BookingId")%>' OnClientClick="javascript: jk(this);" >In progress</asp:LinkButton>
In your function just reference the control attribute:
在您的函数中只需引用 control 属性：
function jk(ctrl) {
var id = ctrl.getAttribute("data-bookingid");
}
By sending the control as a parameter you don't have to worry if the linkbutton is inside another container, i.e. gridview.
通过将控件作为参数发送，您不必担心链接按钮是否在另一个容器内，即 gridview。
