copied!<p><strike>As you don't know which div elements to remove, the only way is removing them all then adding those you get from the AJAX response.</p> <p>To remove them all, use the class that you already have:</p> <pre><code>$(".char").remove(); </code></pre> <p>Add this line to the <code>success</code> function, before iterating over the lines.</strike></p> <p>OK, you can save the ID values returned by the AJAX call in array then remove any that does not exist in the array. Revised function code:</p> <pre><code>success: function(data) { var str = data; var chars = str.split("<br />"); var arrDivIDs = new Array(); for(var i = chars.length - 1; i >= 0 ;i-- ) { chars[i] = chars[i].split('/'); arrDivIDs[chars[i][0]] = true; var o = document.getElementById(chars[i][0]); var aimt = i; if (!o) { if (aimt!=chars.length -1) { $('#gracze').html('<div id="'+chars[aimt][0]+'" class="char"><div id="char_name" style="left:-'+(((chars[aimt][3].length*9)/2)-16)+'px;width:'+(chars[aimt][3].length*9)+'px;">'+chars[aimt][3]+'</div></div>'+$('#gracze').html()); $('#'+chars[aimt][0]).css("top", chars[aimt][2]*32-16+"px"); $('#'+chars[aimt][0]).css("left", chars[aimt][1]*32+"px"); $('#'+chars[aimt][0]).css("z-index", chars[aimt][2]+1); } } else { $('#'+chars[aimt][0]).animate({ "top": chars[aimt][2]*32-16+"px", "left": chars[aimt][1]*32+"px" }, { duration: 300}); $('#'+chars[aimt][0]).css("z-index", chars[aimt][2]); } } $(".char").each(function(index) { if (!arrDivIDs[$(this).attr("id")]) $(this).remove(); }); } </code></pre>
