My JQuery slide animation lags when sliding the #res div.
Any suggestions?
JQuery:
$(document).ready(function(){
$('select.first').change(function(){
$(this).prop('disabled', true);
var codata = $(this).val();
var page = 1;
$.ajax({
type:'POST',
url:'page.php',
dataType:'json',
data:{country:codata, page:page},
success: function(data) {
var result='';
$.each(data, function(i,e) {
result += "<div id='outer'>"+e.sDo+'</div>';
});
$('#res').html(result);
}
}).done(function(){$('#res').slideDown();});
});
});
CSS:
#res {
background-color:gainsboro;
border:1px solid gray;
width:100%;
display:none;
padding-top:10px;
}
#outer {
width:100px;
text-align:center;
border:1px dotted black;
margin:0 0 10px 10px;
display:inline-block;
height:40px;
}
To slideDown an element without it jumping, the element must have a fixed width. Here's a demo to demonstrate. http://jsfiddle.net/WtkUW/1/
The reason for this is jQuery calculates the target height of the element based on its width and its content. If its width is 100%, jQuery can't accurately calculate the height resulting in a jump. The larger the content, the larger the jump.
