<分区>
对不起,我的英语不是很好。我希望我的容器元素调整大小以始终包含其子元素。
访问jsfiddle.net/datakolay/LakYy/
$(document).ready(function() {
var
$document = $(document),
$parent = $("#parent"),
$container = $(".container", $parent),
offset = $container.offset(),
scrollbarSafety = 15;
$container.height($document.height() - offset.top - scrollbarSafety);
$("#eleman,#eleman2")
.draggable(
{
containment: $container,
drag:
function(event, ui)
{
var
$draggee = $(this),
draggeePosition = $draggee.position(),
shouldHeight = draggeePosition.top + $draggee.height() + 15;
if($parent.height() < shouldHeight)
{
$parent.height(shouldHeight);
}
if($parent.height() > shouldHeight)
{
$parent.height(shouldHeight);
}
}
}
);
});
