<button onclick="showModal()">点击弹出模态框</button>

<div class='modal-body' id='modal-body-alert'>

<div class='modal-footer boxFooter' id='modal-footer'>
<button type='button' class='btn btn-default boxButton' data-dismiss='modal'>关闭</button>
<button type='button' class='btn btn-primary boxButton'>保存</button>

</div>
<script src="./js/jquery/jquery-1.11.2.js"></script>
<script src="./js/bootstrap/js/bootstrap.min.js"></script>
<script src="./js/jquery-ui/jquery-ui.min.js"></script>
<script>
var clearFlag = 0;
var count = 3;//设置3秒后自动消失
var showModal = function(){
$("#my-modal-alert").toggle();//显示模态框
$("#my-modal-alert").draggable({//设置模态框可拖动（需要引入jquery-ui.min.js）
handle: ".modal-header"
});
clearFlag = self.setInterval("autoClose()",1000);//每过一秒调用一次autoClose方法
}
var autoClose = function(){
if(count>0){
$("#num").html(count + "秒后窗口将自动关闭");
count--;
}else if(count<=0){
window.clearInterval(clearFlag);
$("#num").html("");
$("#my-modal-alert").fadeOut("slow");
count = 3;
$("#my-modal-alert").toggle();
}
}
</script>
</body>
</html>
注意：1、bootstrap依赖于jquery,引入bootstrap前需要引入jquery
