How can I add a list item in order using jQuery?

Question

Does anyone know how to add an item to a list but do it so it's ordered alphabetically using jQuery? I've got the following code that just adds an item from a dropdown to the end of the list:

$("#projectList").append(
    "<li>"
    + $("#Projects :selected").text()
    + " <span class='removeProject' projectId='" + $("#Projects").val() + "'>Remove</span>"
    + "</li>"
);

but I'd like to be able to insert it in its appropriate place instead of just appending to the end of the existing list.

Any help is greatly appreciated! Thanks!

Answer 1

I think this would work:

var new = $(
    "<li>"
    + $("#Projects :selected").text()
    + " <span class='removeProject' projectId='" + $("#Projects").val() + "'>Remove</span>"
    + "</li>"
);

var firstafteritem = $("#projectList").children().filter( function () {
    return ($(this).text() > $("#Projects :selected").text())
} ).eq(0);

if (firstafteritem.length > 0) firstafteritem.before(new);
else                           $("#projectList").append(new);

The value of firstafteritem will be the first list item that has a text value after the one you're adding. (Or none if it would be last.) Then the if/else would either insert it before that item or at the end of the list.

(This, of course, assumes that the values of your list are already in order.)

<script type="text/javascript">
     $(document).ready(function(){
     $("#doctype li:first").before("<li><a href='intranet/library'>All documents</a></li>");
     });
</script>
