Bootstrap 3 中的“data-target"属性是什么? [英] What is the `data-target` attribute in Bootstrap 3?

问题描述

你能告诉我 Bootstrap 3 使用的 data-target 属性背后的系统或行为是什么吗?

我知道数据切换用于针对图形功能的 Bootstrap 的 API JavaScript.

解决方案

data-target 被引导程序使用，让您的生活更轻松.您(大多数情况下)不需要编写一行 Javascript 即可使用他们预制的 JavaScript 组件.

data-target 属性应该包含一个 CSS 选择器，指向将被更改的 HTML 元素.

来自 BS3 的模态示例代码:

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">启动演示模式<!-- 模态--><div class="modalfade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">[...]

在这个例子中，按钮有data-target="#myModal"，如果你点击它，<div id="myModal">...</div> 将被修改(在这种情况下淡入).发生这种情况是因为 CSS 选择器中的 #myModal 指向具有 myModal 值的 id 属性的元素.

Can you tell me what is the system or behavior behind the data-target attribute used by Bootstrap 3?

I know that data-toggle used to aim API JavaScript of Bootstrap of graphical functionality.

解决方案

data-target is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.

The data-target attribute should contain a CSS selector that points to the HTML Element that will be changed.

Modal Example Code from BS3:

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  [...]
</div>

In this example, the button has data-target="#myModal", if you click on it, <div id="myModal">...</div> will be modified (in this case faded in). This happens because #myModal in CSS selectors points to elements that have an id attribute with the myModal value.
