一、在页面中加入如下代码
<div class="modal fade" tabindex="-1" role="dialog" id="waitingModal"><div class="modal-dialog" role="document"><div class="modal-content"><div class="modal-header"><h4 class="modal-title">正在操作中...</h4></div><div class="modal-body"><div class="progress"><div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="45" aria-valuemin="0" aria-valuemax="100" style="width: 100%"><span class="sr-only">100%</span></div></div></div><div class="modal-footer"><button type="button" disabled class="btn btn-default" data-dismiss="modal">正在操作，请勿关闭或刷新页面！</button></div></div></div></div>
<script>
function showWaiting() {
$('#waitingModal').modal({
keyboard: false,
backdrop: 'static',
show: true
});
}
function hideWaiting() {
$('#waitingModal').modal('hide');
}
</script>
二、使用的地方
显示：showWaiting()
隐藏：hideWaiting()
三、效果
