Bootstrap Modals are created using custom Jquery plugins. It can be used to create modal windows to enrich user experience, or to add practical functions to users. You can use Popovers and Tooltips in Modals.

1. What is a modal window?

This is the effect:

2. Composition

Header (including title and close button)

Middle (main content)

Bottom (mainly for placing operation buttons)

The corresponding layout in the html code is: use the div container element, use the modal, modal-dialog, and modal-cotent styles respectively, and use three header, body, and footer of the pop-up window in the modal-content. Style: modal-header, modal-body, modal-footer, as shown below:

3. Implementation code

<style>
.modal {//该样式是做背景容器的，100%充满全屏，还有当内容很多时，k可以在modal里进行滚动操作
position: fixed;//固定布局的
top: 0;
right: 0; //设置上下左右都为0，表示充满全屏
bottom: 0;
left: 0;
z-index: 1050;//提升z-index，防止其他元素溢出
display: none;//默认不显示
overflow: hidden;
-webkit-overflow-scrolling: touch;//支持移动设备上，触摸进行移动
outline: 0;//消除虚边框
}
.modal-dialog {
position: relative;//相对与Modal元素，进行相对定位
width: auto;//宽度自适应
margin: 10px;//外边距10像素
}
.modal-content {主要对弹窗进行边框，边距，背景色，阴影的处理
position: relative;//
background-color: #fff;
-webkit-background-clip: padding-box;//背景的裁剪区域设置从padding区域向外
background-clip: padding-box;
border: 1px solid #999;
border: 1px solid rgba(0, 0, 0, .2);//透明度设置
border-radius: 6px;
outline: 0;//取消轮廓显示
-webkit-box-shadow: 0 3px 9px rgba(0, 0, 0, .5);
box-shadow: 0 3px 9px rgba(0, 0, 0, .5);
}
.modal-header {//弹窗的头部设置
min-height: 16.42857143px;//最小高度设置
padding: 15px;
border-bottom: 1px solid #e5e5e5;//底部设细线，与modal-body区分
}
.modal-header .close {//关闭按钮
margin-top: -2px;
}
.modal-title {
margin: 0;
line-height: 1.42857143;//头部内部的标题样式
}
.modal-body {//中间内容区域
position: relative;
padding: 15px;
}
.modal-footer {//底部设置
padding: 15px;
text-align: right;//居右对齐，一般都是按钮
border-top: 1px solid #e5e5e5;
}
</style>
<body>
<!-- <button data-toggle="modal" data-target="#popucss" class="btn btn-success" >单击弹出模态窗口</button> --><!-- //触发元素（使用声明式语法）
//弹窗主要内容 --><!-- //下面写id的是js使用方法（使用声明式语法）
//弹窗主要内容 -->
<button id="dianji" class="btn btn-success">单击弹出模态窗口</button>
<!-- 弹窗主要内容 -->
<div class="modal" id="dianjiji"><!-- 第一部分 -->
<div class="modal-dialog"><!-- 第二部分 -->
<div class="modal-content"><!-- 第三部分，主要部分 -->
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
<span aria-hidden="true">&times;</span> <span class="sr-only">Close</span>
</button>
<h2 id="登录系统">登录系统 </h2>
</div>
<div class="modal-body">
<p>弹窗里的具体内容,hhh ajbh </p>
</div>
<div class="modal-footer"> 
<button type="button" 
id="login" class="btn btn-success ">登录</button>
<button type="button" 
id="login" class="btn btn-success ">取消</button>
</div>
</div>
</div>
</div>
<script src="./bootstrap-3.3.5/dist/js/jquery.min.js"></script>
<script src="./bootstrap-3.3.5/dist/js/bootstrap.min.js"></script>
<script src="./bootstrap-3.3.5/dist/js/modal.js"></script>
<script>
$(function() {
$("#dianji").click(function() {
$("#dianjiji").modal("show");
});
})

Four. Usage in Js:

(1) Declarative syntax

data-toggle, data-target, set on the trigger element, the value of data-toggle must be modal, the value of dat-target is: css selector

(2) javascript usage:

1) Use attribute control: background Boolean value is true, then when the background (excluding the pop-up window itself) is clicked, the pop-up window will be closed, otherwise, vice versa.

keyboard 布尔值 值为true,则按esc时，关闭弹窗，否则反之。
$("#dianjiji").modal({
backdrop:true,
keyboard:false,
show:true;
})

2) Use parameter control: toggle $("#mymodal").modal("toggle"), when triggered, the status of the bounce window will be triggered,

Show $(“#mymodal”).modal(“show”), when triggered, displays the pop-up window
Hide $("#mymodal").modal("hide"), when triggered, close

3) Usage control:

Show.bs.modal 在show方法调用时立即触发
Shown.bs.modal 该事件在模态弹窗完全显示给用户之后，触发
Hide.bs.modal 在hide方法调用时，立即触发
Hiden.bs.modal 该事件在模态弹窗隐藏之后触发
使用方法
$(“#mymodal”).on(‘方法名',function(e){
//处理代码。。。
})
