Question

Please look at the following code. I can’t get my values to add up. The digit just adds itself to the back of the string. Wonder any way to go about it.

$("a[name='older_post']").click(function(){
    $("div.main_ads_div a[name='older_post']").remove().fadeOut();
    var last_td_id=parseInt($("table.main_ads_table:last").find("td.load_ads:last").attr("id"),10);
    alert(last_td_id);   //OUTPUTS 38
    $("div.main_ads_div").append('<table class="main_ads_table" col="7" row="7"><tr><td class="load_ads" id="'+last_td_id+1+'"></td><td class="load_ads" id="'+last_td_id+2+'"></td><td class="load_ads" id="'+last_td_id+3+'"></td><td class="load_ads priority" id="'+last_td_id+4+'"></td><td class="load_ads priority" id="'+last_td_id+5+'"></td><td class="load_ads" id="'+last_td_id+6+'"></td><td class="load_ads" id="'+last_td_id+7+'"></td><td class="load_ads" id="'+last_td_id+8+'"></td></tr></table>');
});

So what I’m trying to get here is for the each td that appends, I’m trying to get 39, 40, 41, 42... But I’m getting values such as 381, 382, 383,... etc etc.

Any help here appreciated.

Wrap the addition in parentheses:

 ... + (last_td_id + 7) + ...
