jquery 的val()值复加怎么弄

var hdcval = $("#hdelsecount").val();
                        hdcval += icount + ",";
                        $("#hdelsecount").val(hdcval);

往一个隐藏域里追加值。。
原始是0
icount 是传来的数字
想是

$("#hdelsecount").val(icount+","）；

以为能重复追加值，如1,2,3,4,这样，可是val()这个方法是覆盖的。不是在值里追加字符额。。那个方法是追加的呢？？

$("#hdelsecount").val($("#hdelsecount").val() + icount+","）
