问题 I have a jQuery set of elements that I get from my DOM by calling: $(".some-selector"); All my elements are DIVs each in its own line.

问题 I am working on a script to show in the terminal an empty matrix with dot representing all the elements to be filled. Then, I want to ask to the user which element he wants to select for each position.
