创建叠加层以发送消息

Question

我正在寻找类似Facebook的类似功能，当有人点击发送消息按钮时，div会弹出一个人们可以输入的文本区域。我不知道如何创建叠加层。我看过像Facebox这样的东西，但想要自己创造一些东西。有没有人有关于如何使用页面上的许多元素创建此叠加层的任何好示例或教程？

如果您正在使用jQuery，那么包含和使用jQuery UI并不是一个很大的飞跃。看看这个演示，看看它是否有用。

其中一个最干净的模态是twitter bootstrap中提供的模态。要实现它，您只需使用 jQuery 和 modal.js 。根据您的其他警报请求，您还需要添加 alert.js。如果您不想使用their CSS，则相对容易在CSS中实现：

HTML：

<div class="modal hide fade" id="my-modal">
  <div class="modal-header">
    <a href="#" class="close">&times;</a>
    <h3>Modal Heading</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" class="btn primary">Primary</a>
    <a href="#" class="btn secondary">Secondary</a>
  </div>
</div>

<div class="alert-message success hide fade in" data-alert="alert">
    <a class="close" href="#">&times;</a>
    <p><strong>Well done!</strong> You successfully <a href="#">read this</a> alert message.</p>
</div>

JS：

$('#my-modal').modal(true);
$(".alert-message").alert();
$('#my-modal').bind('hidden', function () {
    $(".alert-message").removeClass("hide");
});

您最终可能会使用bind()以外的其他内容来启动removeClass()功能。

CSS：

.hide {
  display: none;
}
.fade {
  -webkit-transition: opacity 0.15s linear;
  -moz-transition: opacity 0.15s linear;
  -ms-transition: opacity 0.15s linear;

Answer 3

您可以使用jQuery BlockUI Plugin。 Demos tab上的第一个演示“登录表单”与您描述的内容类似。

Answer 4

您可以使用jQuery的模态对话框http://jqueryui.com/demos/dialog/#modal-message。

易于使用，支持主题和大量自定义。
