Question

I want some return about dom manipulation. I think we can save elements’ status in several ways. For exemple, you want to make an element “inserted”, what do i have to use? :

• Add css class as “inserted”
• Save an attribute with .data(“inserted”,true)
• Push my element in a global array containing all “inserted” elements
• …

But what is the best way? Maybe the solution is to use all possibilities. I don’t know.

That’s a general question. I don’t have a specific problem, but i am starting developing a huge javascript application and i want to choose my rules 🙂

Answer 1

Do you want selected elements to look in a specific way?
–> Use the css-class

Do you want to check whether a specific element is selected at a different place in code?
–> Use .data

Do you want to do something to all selected elements?
–> Use an array.

If you plan to do multiple of the things above, you can also combine the approaches.
