What is the difference in jQuery between prop and data? You can just prop ('blabla', value), why use data ()?

I will add: if you need to save any info to the element, then prop or data is better?

    .data allows you to get the date attribute value and cache it in an internal object. Cannot set attribute .

    .prop sets the value of a specific element property.

    If you just need to store some information, it is better to use data .

    • Once this caching got me great. An extra function on the background "it's time to retire for a long time, but we still want to explode" IMHO. - user207618 2:57
    • @Other and what about the problems? Maybe data () won't work for me either? What was the complexity of caching? - bsbak
    • @bsbak, it was not a matter of complexity, I just did not need caching, but it was. - user207618
     elem.data('property-name') аналогично elem.prop('data-property-name')

    That's all the difference

    • not really similar - Grundy
    • @Grundy What is my mistake? - ilyaplot
    • one
      that data takes values ​​from the date of the attribute, but saves this value to its internal object. prop does not take values ​​from attributes, it takes values ​​from properties. Just add a snippet to your answer, demonstrating that these calls are really similar - Grundy
