基于bootstrap模态框的日期选择器

近来由于工作需求，以bootstrap模态框+DIV+CSS+JS做了一个适用于移动端的日期选择器，能够满足多样的需求，目前处于第一个版本，后续可能会继续更新。废话不多说，直接进入制作过程。

首先，需要引入一些js文件,bootstrap.css和是模态框使用需要，bootstrap.min.js，而controll_selectdate.js是实现选择器所有功能的代码。

<link href="css/bootstrap.css" rel="stylesheet" type="text/css" />
<script src="js/bootstrap.min.js" type="text/javascript"></script>
<script src="js/controll_selectdate.js" type="text/javascript"></script>

下面是对模态框内的一些样式定义，这里的样式会影响到原有样式，请注意放置位置

.modal-footer .btn+.btn {
    min- 30%;
    margin-left: 0
}

.modal-footer .btn {
    min- 30%;
    margin-left: 0
}
.modal-date {
     15%;
    display: inline-block;
    text-align: center
}

.modal-year {
     49%;
    display: inline-block;
    text-align: center
}

.modal-month {
     23%;
    display: inline-block;
    text-align: center
}   
.modal-dialog {
    margin-top: 30%;
}

ul {
    display: inline-block;
    margin: 0 auto;
     49%;
    height: 126px;
    overflow: hidden;
    overflow-y: scroll;
    overflow-x: hidden;
}

.list-group-item {
    height: 42px;
    border: none;
    background-color: rgba(0, 0, 0, 0);
}
.selected {
    font-size: 20px;
    font-weight: 10px;
}

.modal {
     100%;
    z-index:999999999
}

.year {
    
}

.month {
    
}

.date {
    
}

下面则是controll_selectdate.js的内容

            var initday = initdate.getDate();
            $('#headBlock .selectedate').text(
                    (inityear - 7) + "年-" + inityear + "年")
        })
