Bootstrap dropdown a标签或者button 点击事件

$(function() {
    $("ul.dropdown-menu").on("click", "[data-stopPropagation]", function(e) {
　　 ////[data-stopPropagation]为选择器，li里面点击事件选择器

　　 e.stopPropagation(); 
}); 
});

定义属性值data-stopPropagation的元素点击时停止传播事件

<ul class="dropdown-menu">
    <li>
        <-- Do not close when clicking this link -->
        <a href="#" data-stopPropagation="true">
            ...
        </a>
    </li>
    <li>
        <-- Do not close when clicking this checkbox -->
        <input type="checkbox" data-stopPropagation="true" ... >
    </li>

    <-- Do not close when clicking anything in this LI -->
    <li data-stopPropagation="true">
        ...
    </li>
</ul>

之后需要时加上该属性即可。
