js+css实现模态层效果_html/css_WEB-ITnose

模态层效果

下面说说在写模态层的时候的思路：通过可配置的参数width，height，title以及content用来设定弹出的信息框显示的内容，并通过可配置参数container用来设定模态层显示的区域。思路很简单，主要是一些css样式和js处理，详见源码：

modal.css

html,body{    font-size: 12px;    font-family: "微软雅黑";}.modal{    position: absolute;    top:0px;    left: 0px;    border: 1px solid #000;    background: #555;    opacity: 0.4;}.infowin{    border: 1px solid #777777;    background: #fff;    box-shadow: 0 0 0.75em #777777;    -moz-box-shadow: 0 0 0.75em #777777;    -webkit-box-shadow: 0 0 0.75em #777777;    -o-box-shadow: 0 0 0.75em #777777;    border-radius: 5px;    -moz-border-radius: 5px;    -webkit-border-radius: 5px;    -o-border-radius: 5px;} .title{    border-bottom: 1px solid #777777;}.title_content{    padding: 5px;    padding-left: 10px;    font-size: 14px;    font-family: "微软雅黑";    font-weight: bold;}.close{    background: url(close.png) no-repeat;    width: 25px;    height: 25px;    float: right;}.close:hover{    cursor: pointer;}.content{    padding-left: 10px;    padding-top: 10px;}

(function($){    $.fn.modalInfowindow = function(options){        var defaults = {};        var options = $.extend(defaults, options);        var container=$(this);        var width=options.width, height=options.height, title=options.title, content=options.content;        //模态层容器        var modal=$("
");        modal.css("width","100%");        modal.css("height","100%");        //模态层        var modal_div=$("
");        modal_div.css("width","100%");        modal_div.css("height","100%");        //信息框        var infoWin=$("
");        infoWin.css("width",width+"px");        infoWin.css("height",height+"px");        infoWin.css("position","absolute");        infoWin.css("top",(container.height()-height)/2+"px");        infoWin.css("left",(container.width()-width)/2+"px");        //标题        var infoWin_title=$("
");        var infoWin_title_close=$("
")        infoWin_title_close.on("click",function(){            console.log("Close Modal!");            modal.hide();        });        var infoWin_title_content=$("
")        infoWin_title_content.append(title);        infoWin_title.append(infoWin_title_close);        infoWin_title.append(infoWin_title_content);        //内容        var infoWin_content=$("
");        infoWin_content.append(content);        //信息框添加标题和内容        infoWin.append(infoWin_title);        infoWin.append(infoWin_content);        //模态层容器添加模态层和信息框        modal.append(modal_div);        modal.append(infoWin);        //将模态层添加到容器        container.append(modal);    }})(jQuery);
