Differences between jQuery.data() and .data()?

Question

So, i was reading the jquery documentation and i couldn't identify the differences between the functions jQuery.data() and .data() . What are the main difference between those functions?

Here is the link to documentation: Doc jquery

Answer 1

From the link you provided - it would appear it is simply just an older way of calling the same functionality in a more 'vanilla javascript' way...but it would appear there is one actual difference listed.

Note: This is a low-level method; a more convenient .data() is also available.

Regarding HTML5 data-* attributes: This low-level method does NOT retrieve the data-* attributes unless the more convenient .data() method has already retrieved them.

Answer 2

后者只是前者的一种更方便的语法： $.(domElement, 'key')和$('selector').data('key')做同样的事情。
