js弹窗 js弹出DIV,并使整个页面背景变暗

1.首先写一个遮罩层div,然后再写一个弹窗的div

<!-- 遮罩层 -->
<div id="cover" style="background: #000; position: absolute; left: 0px; top: 0px; width: 100%;  filter: alpha(opacity=30); opacity: 0.3; display: none; z-index: 2 ">
    
</div>

<!-- 弹窗 -->
<div id="showdiv" style="width: 80%; margin: 0 auto; height: 9.5rem; border: 1px solid #999; display: none; position: absolute; top: 40%; left: 10%; z-index: 3; background: #fff">
    <!-- 标题 -->
    <div style="background: #F8F7F7; width: 100%; height: 2rem; font-size: 0.65rem; line-height: 2rem; border: 1px solid #999; text-align: center;" >
        提示
    </div>
    <!-- 内容 -->
    <div style="text-indent: 50px; height: 4rem; font-size: 0.5rem; padding: 0.5rem; line-height: 1rem; "></div>
    <!-- 按钮 -->
    <div style="background: #418BCA; width: 80%; margin: 0 auto; height: 1.5rem; line-height: 1.5rem; text-align: center;color: #fff;margin-top: 1rem; -moz-border-radius: .128rem; -webkit-border-radius: .128rem; border-radius: .128rem;font-size: .59733rem;" onclick="closeWindow()">
        确 定
    </div>
</div>

 

js代码:(把jq引进来)

<script type="text/javascript">
   // 弹窗 function showWindow(showmsg) { $('#showdiv').show(); //显示弹窗 $('.content').append(showmsg); //追加内容 $('#cover').css('display','block'); //显示遮罩层 } // 关闭弹窗 function closeWindow() { $('#showdiv').hide(); //隐藏弹窗 $('#cover').css('display','none'); //显示遮罩层 $('#showdiv .content').html(""); //清空追加的内容 }

//调用
showWindow('
js弹窗 js弹出DIV,并使整个页面背景变暗');

</script>

 

 

效果:
