什么是“生成的”在某些HTML标签中使用的属性？ [英] What is the "generated" attribute seen in some HTML tag used for?

问题描述

我看到它用于HTML标签标签，但我有一种感觉，它可以用于大多数HTML标签。我可以猜测它的意思。但我更加好奇使用它的好处。我试图谷歌的一些参考，但找不到任何，所以我来找你的专家。

例如：

 < label for =first_name generated =trueclass =error>此栏位为必填项。< / label> 
  

解决方案

您可以将其用作JavaScript和/或CSS。

例如...

CSS

  label [generated = true] {
 color：#ccc; 
 
  

JavaScript

  var labels = document.getElementsByTagName（'label'）; 
 
 for（var i = 0，length = labels.length; i< length; i ++）{
 if（labels [i] .getAttribute（'generated'）==='真'）{
 //做点什么。 
} 
} 
  

它常用于JavaScript生成的元素，例如由 jQuery验证插件创建的标签元素。

您可以使用jQuery来清理生成的元素...

  $（ '* [生成=真'）除去（）; 
  

I saw it used in a HTML label tag but I have a feeling that it can be used with most HTML tags. I can kinda guess what it means. But I am more curious about what's the benefit of using it. I tried to google for some reference about it but couldn't find any, so I come to you experts. Thanks.

Example:

<label for="first_name" generated="true" class="error">This field is required.</label>

解决方案

You could use it as a hook for JavaScript and/or CSS.

For example...

CSS

label[generated=true] {
   color: #ccc;
}

JavaScript

var labels = document.getElementsByTagName('label');

for (var i = 0, length = labels.length; i < length; i++) {
    if (labels[i].getAttribute('generated') === 'true') {
       // Do something.
    }
}

It is often used on JavaScript generated elements, such as the label elements created by the jQuery Validation plugin.

You could use jQuery to clean up generated elements with...

$('*[generated=true]').remove();
