javascript - Repeating fadein on news feed -
a page of website has news feed use ajax return each day 1 @ time , display it. want each days news appear fade in.
the problem fade in repeats, each day return
html
<div id='newsdiv' class='newsdiv'></div> javascript ajax call
document.getelementbyid('newsdiv').innerhtml += xmlhttp.responsetext;  css
@keyframes fadein {     { opacity: 0; }       { opacity: 1; } } /* firefox < 16 */ @-moz-keyframes fadein {     { opacity: 0; }       { opacity: 1; } } /* safari, chrome , opera > 12.1 */ @-webkit-keyframes fadein {     { opacity: 0; }       { opacity: 1; } } /* internet explorer */ @-ms-keyframes fadein {     { opacity: 0; }       { opacity: 1; } } /* opera < 12.1 */  @-o-keyframes fadein {     { opacity: 0; }       { opacity: 1; } }  .divfadein, .centrescreen, .tbl_houseform {     -webkit-animation: fadein 3s; /* safari, chrome , opera > 12.1 */        -moz-animation: fadein 3s; /* firefox < 16 */         -ms-animation: fadein 3s; /* internet explorer */          -o-animation: fadein 3s; /* opera < 12.1 */             animation: fadein 3s;      -webkit-animation-iteration-count: 1;        -moz-animation-iteration-count: 1;         -ms-animation-iteration-count: 1;          -o-animation-iteration-count: 1;             animation-iteration-count: 1;  -webkit-animation-fill-mode: forwards;    -moz-animation-fill-mode: forwards;     -ms-animation-fill-mode: forwards;      -o-animation-fill-mode: forwards;         animation-fill-mode: forwards;  } if put fade in parent new feed, it'll fade in when first day returned, not of following days.
if put fade in on child div, it'll fade in when each , every day returned (i.e. repeating fade in when next day returned).
how stop happening? how stop each day fading in more once?
i understand each day fading in because div "divnews" being re-populated. understanding doesn't solve problem.
you should append new element in parent div instead of updating whole content.
you can return json ajax call , create new element on fly returned data on callback function.
a simple example using jquery :
$.get('your_url',function(data){    var el = $('<div></div>').addclass('animation_class').html(data.key);   $('#newsdiv').append(el);  });
