如何使用jQuery更改HTML属性名称？

I would like to change all the names of the attributes where class="testingCase" throughout all my whole html document.

我想在整个html文档中更改class =“testingCase”的所有属性名称。

e.g. Change:

例如更改：

<a class="testingCase" href="#" title="name of testing case">Blabla</a>
<a class="testingCase" href="#" title="name of another testing case">Bloo</a>

To this:

对此：

<a class="testingCase" href="#" newTitleName="name of testing case">Blabla</a>`
<a class="testingCase" href="#" newTitleName="name of another testing case">Bloo</a>`

I was thinking of a find and replace but that seems a lot of code for something so easy. Is there a jQuery function for this or a simple method?

我正在考虑一个查找和替换，但似乎很多代码很容易。这个或简单方法有jQuery函数吗？

I don't think you can "rename" an attribute, but you can create new attributes and remove other ones...

我不认为你可以“重命名”一个属性，但是你可以创建新属性并删除其他属性......

$('a.testingCase[title]').each(function() {
  var $t = $(this);
  $t.attr({
      newTitleName: $t.attr('title'),
    })
    .removeAttr('title');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a class="testingCase" href="#" title="name of testing case">Blabla</a>
<a class="testingCase" href="#" title="name of another testing case">Bloo</a>

Edit: added in the bit that makes it only select a elements with class="testingCase"

编辑：在该位中添加，使其仅选择具有class =“testingCase”的元素

I don't think you can change an attribute name but what you can do is :

我认为您不能更改属性名称，但您可以做的是：

get all the <a> tags with a title attribute;
获取所有带有title属性的标签;
foreach of them, create a newTitleName attribute with the same value as the title;
foreach，创建一个newTitleName属性，其值与标题相同;
then delete the title attribute.
然后删除title属性。

JQuery let you do that with builtin functions this way :

JQuery允许您通过这种方式使用内置函数：

/* get all <a> with a "title" attribute that are testingCase
then apply an anonymous function on each of them */

$('a.testingCase[title]').each(function() {   

    /* create a jquery object from the <a> DOM object */
    var $a_with_title = $(this);    

    /* add the new attribute with the title value */
    $a_with_title.attr("newTitleName", $a_with_title.getAttribute('title'));

    /* remove the old attribute */
    $a_with_title.removeAttr('title'); 

});

A little later but this link has a great jquery function extension:

稍后，但这个链接有一个很棒的jquery函数扩展：

jQuery.fn.extend({
  renameAttr: function( name, newName, removeData ) {
    var val;
    return this.each(function() {
      val = jQuery.attr( this, name );
      jQuery.attr( this, newName, val );
      jQuery.removeAttr( this, name );
      // remove original data
      if (removeData !== false){
        jQuery.removeData( this, name.replace('data-','') );
      }
    });
  }
});

Example

例

// $(selector).renameAttr(original-attr, new-attr, removeData);
 
// removeData flag is true by default
$('#test').renameAttr('data-test', 'data-new' );
 
// removeData flag set to false will not remove the
// .data("test") value
$('#test').renameAttr('data-test', 'data-new', false );

I DID NOT WRITE THIS. BUT I DID TEST IS WITH JQ 1.10. THE CODE IS FROM THE LINK.

我不写这个。但我测试的是JQ 1.10。该代码来自链接。

Here's a simple jquery-style plugin that gives you a renameAttr method:

这是一个简单的jquery风格的插件，它为您提供了一个renameAttr方法：

// Rename an entity attribute
jQuery.fn.renameAttr = function(oldName, newName) {
    var args = arguments[0] || {}; 
    var o = $(this[0]) 

       o
        .attr(
            newName, o.attr(oldName)
        )
        .removeAttr(oldName)
        ;
};

There is also this example which adds an option to remove the data for the old attribute.

还有一个示例添加了一个选项来删除旧属性的数据。

One liner

一个班轮

$('selector').replaceWith($('selector')[0].outerHTML.replace("oldName=","newName="));

worked great for me when I needed to strip a prefix from all of my attributes

当我需要从所有属性中删除前缀时，对我来说很有用

$('selector').replaceWith($('selector')[0].outerHTML.(/prefix\-/g,""));

same answer as @nickf but cleaner code:

与@nickf相同的答案，但更清晰的代码：

$('a.testingCase[title]').each(function() {
    var curElem = $(this);
    curElem.attr("newTitleName", curElem.attr('title')).removeAttr('title');
});
