get height of jQuery popup when it shows up -

-

i want geht height of popup when loaded can set left/top value , make sure not out of viewport. @ first time popup toggled, there's hight of static div available, not including content ajax.


$(".td_id").click(function(e) {     var leftval = e.pagex+10;     var topval  = e.pagey;     var bodytop = document.documentelement.scrolltop;     topval     -= bodytop;     win         = $(window).height();     wincenter   = win / 2;     $.post("ajax.php",{do:'load_data'},function(table){                             $(".popup tbody").html(table);                         }     );     $(".popup").toggle();     popup = $(".popup").height();     if (topval > wincenter) topval -= popup;     if ((topval+popup) > (win + 10)) topval = win-10-popup;     if (topval < 10) topval = 10;     $(".popup").css({left:leftval,top:topval}); });




how height after content received , added popup div?

the popup seems getting content ajax post, , trying calculate height outside post callback (before popup gets content ajax post), hence height not calculated proper. try replacing height calculation code inside ajax post success callback function, as:

... $.post("ajax.php",{do:'load_data'},function(table){     $(".popup tbody").html(table);      $(".popup").toggle();     popup = $(".popup").height();     if (topval > wincenter) topval -= popup;     if ((topval+popup) > (win + 10)) topval = win-10-popup;     if (topval < 10) topval = 10;     $(".popup").css({left:leftval,top:topval}); }); ...
