首先，CSS -调整这无论你喜欢:

a.selected {
  background-color:#1F75CC;
  color:white;
  z-index:100;
}

.messagepop {
  background-color:#FFFFFF;
  border:1px solid #999999;
  cursor:default;
  display:none;
  margin-top: 15px;
  position:absolute;
  text-align:left;
  width:394px;
  z-index:50;
  padding: 25px 25px 20px;
}

label {
  display: block;
  margin-bottom: 3px;
  padding-left: 15px;
  text-indent: -15px;
}

.messagepop p, .messagepop.div {
  border-bottom: 1px solid #EFEFEF;
  margin: 8px 0;
  padding-bottom: 8px;
}

JavaScript:

function deselect(e) {
  $('.pop').slideFadeToggle(function() {
    e.removeClass('selected');
  });    
}

$(function() {
  $('#contact').on('click', function() {
    if($(this).hasClass('selected')) {
      deselect($(this));               
    } else {
      $(this).addClass('selected');
      $('.pop').slideFadeToggle();
    }
    return false;
  });

  $('.close').on('click', function() {
    deselect($('#contact'));
    return false;
  });
});

$.fn.slideFadeToggle = function(easing, callback) {
  return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};

最后是html:

<div class="messagepop pop">
  <form method="post" id="new_message" action="/messages">
    <p><label for="email">Your email or name</label><input type="text" size="30" name="email" id="email" /></p>
    <p><label for="body">Message</label><textarea rows="6" name="body" id="body" cols="35"></textarea></p>
    <p><input type="submit" value="Send Message" name="commit" id="message_submit"/> or <a class="close" href="/">Cancel</a></p>
  </form>
</div>

<a href="/contact" id="contact">Contact Us</a>

下面是一个jsfiddle演示和实现。

根据具体情况，您可能希望通过ajax调用加载弹出式内容。如果可能的话，最好避免这种情况，因为它可能会让用户在看到内容之前有更大的延迟。如果您采用这种方法，这里有一些您需要做的更改。

HTML就变成:

<div>
    <div class="messagepop pop"></div> 
    <a href="/contact" id="contact">Contact Us</a>
</div>

JavaScript的大意是:

$("#contact").on('click', function() {
    if($(this).hasClass("selected")) {
        deselect();               
    } else {
        $(this).addClass("selected");
        $.get(this.href, function(data) {
            $(".pop").html(data).slideFadeToggle(function() { 
                $("input[type=text]:first").focus();
            });
        }
    }
    return false;
});

查看jQuery UI对话框。你可以这样使用它:

jQuery:

$(document).ready(function() {
    $("#dialog").dialog();
});

标记:

<div id="dialog" title="Dialog Title">I'm in a dialog</div>

完成了!

请记住，这是最简单的用例，我建议您阅读文档，以更好地了解可以用它做什么。

让我们试试....如何创建一个简单的弹出窗口使用HTML, CSS和jquery…

$(function() { // Open Popup $('[popup-open]').on('click', function() { var popup_name = $(this).attr('popup-open'); $('[popup-name="' + popup_name + '"]').fadeIn(300); }); // Close Popup $('[popup-close]').on('click', function() { var popup_name = $(this).attr('popup-close'); $('[popup-name="' + popup_name + '"]').fadeOut(300); }); // Close Popup When Click Outside $('.popup').on('click', function() { var popup_name = $(this).find('[popup-close]').attr('popup-close'); $('[popup-name="' + popup_name + '"]').fadeOut(300); }).children().click(function() { return false; }); }); body { font-family:Arial, Helvetica, sans-serif; } p { font-size: 16px; line-height: 26px; letter-spacing: 0.5px; color: #484848; } /* Popup Open button */ .open-button{ color:#FFF; background:#0066CC; padding:10px; text-decoration:none; border:1px solid #0157ad; border-radius:3px; } .open-button:hover{ background:#01478e; } .popup { position:fixed; top:0px; left:0px; background:rgba(0,0,0,0.75); width:100%; height:100%; display:none; } /* Popup inner div */ .popup-content { width: 700px; margin: 0 auto; box-sizing: border-box; padding: 40px; margin-top: 100px; box-shadow: 0px 2px 6px rgba(0,0,0,1); border-radius: 3px; background: #fff; position: relative; } /* Popup close button */ .close-button { width: 25px; height: 25px; position: absolute; top: -10px; right: -10px; border-radius: 20px; background: rgba(0,0,0,0.8); font-size: 20px; text-align: center; color: #fff; text-decoration:none; } .close-button:hover { background: rgba(0,0,0,1); } @media screen and (max-width: 720px) { .popup-content { width:90%; } } <!DOCTYPE html> <html> <head> <title> Popup </title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> </head> <body> <a class="open-button" popup-open="popup-1" href="javascript:void(0)"> Popup Preview</a> <div class="popup" popup-name="popup-1"> <div class="popup-content"> <h2>Title of Popup </h2> <p>Popup 1 content will be here.

极其轻量级的模态弹出插件。 POPELT - http://welbour.com/labs/popelt/

它是轻量级的，支持嵌套弹出窗口，面向对象，支持动态按钮，响应式等等。 下一次更新将包括弹出Ajax表单提交等。

只有CSS弹出逻辑!试着去做。简单!我想这在将来可能会很流行

            <a href="#openModal">OPEN</a>

            <div id="openModal" class="modalDialog">
                <div>
                    <a href="#close"  class="close">X</a>
                    <h2>MODAL</h2>

                </div>
            </div>


.modalDialog {
    position: fixed;
    font-family: Arial, Helvetica, sans-serif;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: rgba(0,0,0,0.8);
    z-index: 99999;
    -webkit-transition: opacity 400ms ease-in;
    -moz-transition: opacity 400ms ease-in;
    transition: opacity 400ms ease-in;
    display: none;
    pointer-events: none;
}

.modalDialog:target {
    display: block;
    pointer-events: auto;
}

.modalDialog > div {
    width: 400px;
    position: relative;
    margin: 10% auto;
    padding: 5px 20px 13px 20px;
    border-radius: 10px;
    background: #fff;
    background: -moz-linear-gradient(#fff, #999);
    background: -webkit-linear-gradient(#fff, #999);
    background: -o-linear-gradient(#fff, #999);
}
