Using jQuery, how can I select elements by multiple data-attributes?
提问by Aaron
Consider this array of ptags indexed by data attributes.
考虑这个p由数据属性索引的标签数组。
<p class='my-class' data-id='0' data-id-index='1'></p>
<p class='my-class' data-id='0' data-id-index='2'></p>
<p class='my-class' data-id='1' data-id-index='1'></p>
<p class='my-class' data-id='1' data-id-index='2'></p>
To select a pby data-idand append text I can use:
要选择pbydata-id并附加文本，我可以使用：
$('.my-class[data-id="' + dataId + '"]').append(myText);
The above will append myTextto all ptags with the same data-id. But what about if I wanted to select by both data-idand data-id-index?
以上内容将附加myText到所有p具有相同data-id. 但是如果我想同时选择data-id和data-id-index呢？

Do the same as you already did... the attribute selectors can be chained:
和你已经做的一样......属性选择器可以链接：
$('.my-class[data-id="' + dataId + '"][data-id-index="'+dataIdIndex+'"]').append(myText);
