The first one: The page mask pop-up box is the most common situation. Use jQuery to complete the page mask pop-up box. The main skills used are JQuery, css and html.
The html code is as follows:
<div id="main"><a href="javascript:showBg();">点击这里查看效果</a> <div id="fullbg"></div> <div id="dialog"> <p class="close"><a href="#" onclick="closeBg();">封闭</a></p> <div>正在加载,请稍后....</div> </div> </div>
The css code is as follows:
body { font-family:Arial, Helvetica, sans-serif; font-size:12px; margin:0; } #main { height:1800px; padding-top:90px; text-align:center; } #fullbg { bac千克round-color:gray; left:0; opacity:0.5; position:absolute; top:0; z-index:3; filter:alpha(opacity=50); -moz-opacity:0.5; -khtml-opacity:0.5; } #dialog { bac公斤round-color:#fff; border:5px solid rgba(0,0,0, 0.4); height:400px; left:50%; margin:-200px 0 0 -200px; padding:1px; position:fixed !important; /* 浮动对话框 */ position:absolute; top:50%; width:400px; z-index:5; border-radius:5px; display:none; } #dialog p { margin:0 0 12px; height:24px; line-height:24px; bac公斤round:#CCCCCC; } #dialog p.close { text-align:right; padding-right:10px; } #dialog p.close a { color:#fff; text-decoration:none; }
The jQuery code is as follows:
<script type="text/javascript"> //展示灰色 jQuery 遮罩层 function showBg() { var bh = $("body").height(); var bw = $("body").width(); $("#fullbg").css({ height:bh, width:bw, display:"block" }); $("#dialog").show(); } //关闭灰色 jQuery 遮罩 function closeBg() { $("#fullbg,#dialog").hide(); } </script>
The second one: Simply create a jQuery mask layer. Of course, it can also be made into a public function for easy use many times in the future. This tutorial is suitable for novices.
First give the html:
<p class="showbtn"><a href="javascript:void(0);">显示遮罩层</a></p> <div id="bg"></div> <div class="box" style="display:none"> <h2>jQuery 学习交流<a href="#" class="close">关闭</a></h2> <div class="list"> <ul> <li>脚本之家</li> <li>脚本之家</li> <li>脚本之家</li> </ul> </div> </div>
The style of the mask layer is as follows:
/* box */ .box{position:absolute;width:600px;left:50%;height:auto;z-index:100;background-color:#fff;border:1px #ddd solid;padding:1px;} .box h2{height:25px;font-size:14px;background-color:#aaa;position:relative;padding-left:10px;line-height:25px;color:#fff;} .box h2 a{position:absolute;right:5px;font-size:12px;color:#fff;} .box .list{padding:10px;} .box .list li{height:24px;line-height:24px;} .box .list li span{margin:0 5px 0 0;font-family:"宋体";font-size:12px;font-weight:400;color:#ddd;} .showbtn {font:bold 24px '微软雅黑';} #bg{background-color:#666;position:absolute;z-index:99;left:0;top:0;display:none;width:100%;height:100%;opacity:0.5;filter: alpha(opacity=50);-moz-opacity: 0.5;}
Finally, jQuery is used to display and hide the popup layer:
$(function () { $(".showbtn").click(function () { $("#bg").css({ display: "block", height: $(document).height() }); var $box = $('.box'); $box.css({ //设置弹出层距离左边的位置 left: ($("body").width() - $box.width()) / 2 - 20 + "px", //设置弹出层距离上面的位置 top: ($(window).height() - $box.height()) / 2 + $(window).scrollTop() + "px", display: "block" }); }); //点击关闭按钮的时候,遮罩层关闭 $(".close").click(function () { $("#bg,.box").css("display", "none"); }); });
Summary: The idea of using jQuery to implement masking is to trigger the masking layer when the button is clicked, and let the masking layer cover the entire page through the css level z-index of the popup layer, and at the same time, through the css level z-index of the popup layer Above the mask layer so that the popup layer is highlighted. Then when you click the close pop-up layer button, the pop-up layer will be hidden, and the mask layer will also be hidden. This method of writing is relatively fast. I will write this code into a public function when I have time later, so that it can be called multiple times.
