About boostrap’s modal hidden problem (front-end framework)

Modal (modal box)

First, introduce the file environment of boostrap and Jquery:

    <link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css">
    <script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script>
    <script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>

Usually a button or link triggers the modal

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">开始演示模态框</button><!-- 模态框（Modal） -->

First add a large div, fade: fade in and fade out effect aria- hidden is to hide the modal box

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true")

Then under modal-content, insert modal-header, modal-body, modal-footer

<div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
                <h4 class="modal-title" id="myModalLabel">模态框（Modal）标题</h4>
            </div>
            <div class="modal-body">在这里添加一些文本</div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
                <button type="button" class="btn btn-primary">提交更改</button>
            </div>
        </div><!-- /.modal-content -->

× which is the symbol of X, Click Close or x or click "Ese" to exit the modal box

<button type="button" class="btn btn-primary" onclick="user_del()" id="user-change">提交更改</button>

 function user_del(){
    $("#user").modal('hide');
