jquery .trigger() doesn't seem to work

This is my code :

$(document).ready(function () {
//alert("wa");
$("#wis").trigger('click');
$("#wis,#wib").click(function (){
    alert("clciked");
    if(!$(this).hasClass("dealsb")) {

        $(".dealb").removeClass("dealsb");
        $(this).addClass("dealsb");
        var id=$(this).attr("id");
        $.post("deals.php",{'r开发者_开发知识库eq':id},function(data){
            //alert("works");
            $("#deals").html(data);});


        }

    }); 
});
</script>
<div id='wib' class='dealb'>What I've Purchased</div><div id='wis' class='dealb'>What I've Sold</div>
<div id="deals" style='position:absolute;left:0px;top:100px;width:600px;height:300px'></div>

Here $("#wis").trigger('click'); doesn't seem to work. When I click #wis or #wib though, the alert gets fired off and everything runs perfectly.

You're triggering it before you add the click handler, so the behavior you're seeing makes perfect sense. Move the trigger to the end of your <script> tag and you should be set.
