How to pass value from HTML Anchor to JavaScript function

I want to pass a value from listview layout template  to javascript function.

<asp:ListView ID="ListviewInnerComent" runat="server" DataKeyNames="ID"                                                               OnItemDataBound="ListviewInnerComent_ItemDataBound" OnItemCommand="ListviewInnerComent_ItemCommand">
    <LayoutTemplate>
                                                                
     <ul id="itemPlaceholderContainer"runat="server">
       <li  id="itemPlaceholder" runat="server">
                                                                                
         </li></ul>
