下拉显示框显示不出来，为什么
<script type="text/javascript" src="jquery/jquery-3.1.0.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#search_input").bind('keyup',function(){
$("#search_suggest").show().css({
top:$("#search_form").offset().top,
left:$("#search_form").offset().left,
position:absolute;
})
})
})
</script>
