注意使用modal的时候最外层多套了一个div，因为如果一个页面定义两个modal时，另一个弹不出来，原因不明。
js显示弹窗

$("#listModal").modal({backdrop:false});

html定义弹窗

<!-- 模态框（Modal） -->
    <div>
        <div class="modal fade" id="editModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">
