我有一个从链接启动的引导模式。大约 3 秒钟,它只是空白,而 AJAX 查询从数据库中获取数据。如何实现某种加载指示器?twitter bootstrap 是否默认提供此功能?
编辑:模态的 JS 代码
<script type="text/javascript">
$('#myModal').modal('hide');
$('div.divBox a').click(function(){
var vendor = $(this).text();
$('#myModal').off('show');
$('#myModal').on('show', function(){
$.ajax({
type: "GET",
url: "ip.php",
data: "id=" + vendor,
success: function(html){
$("#modal-body").html(html);
$(".modal-header h3").html(vendor);
$('.countstable1').dataTable({
"sDom": "T<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span6'i><'span6'p>>",
"sPaginationType": "bootstrap",
"oLanguage": {
"sLengthMenu": "_MENU_ records per page"
},
"aaSorting":[[0, "desc"]],
"iDisplayLength": 10,
"oTableTools": {
"sSwfPath": "swf/copy_csv_xls_pdf.swf",
"aButtons": ["csv", "pdf"]
}
});
}
});
});
});
$('#myModal').on('hide', function () {
$("#modal-body").empty();
});
</script>
