I have a list of documents and different actions performed for each records. To delete the record i need the id to pass to the controller. I use JQuery to perform deletion. In it I need to Id of the record. The Following is my view:

<script type="text/javascript">
    $(function() {
        $(".delete_link").live("click", function(e) {
            alert("Hi");
            e.preventDefault();
            if (confirm("Are you sure you want to delete?")) {

               $.post("/BuildDocument/DeleteBuildDocument", {need to pass id here..});
            }
            else {
                $.post("/BuildDocument/IndexBuildDocument");
            }
        });
    });
</script>

$.post("/BuildDocument/DeleteBuildDocument", {need to pass id here..});  

need the id(BldDocId). How can i get it?

Any help will be appreciated.

        $(".delete_link").live("click", function(e) {
            var $link = $(this);
            alert("Hi");
            e.preventDefault();
            if (confirm("Are you sure you want to delete?")) {

               $.post("/BuildDocument/DeleteBuildDocument", { var id = $link.attr('bldDocId'); });
            }
            else {
                $.post("/BuildDocument/IndexBuildDocument");
            }
        });

I don't know asp.net. But it seems the class name is "delete-link", from

new {@class ="delete-link"}

If my mistake, ignore me.
