How bootstrap adds multiple modal boxes and solves the problem that each modal box does not affect each other

Key point

The data-target="#myModal" of the click button of the first modal box corresponds to the id="myModal" of the first modal box; so the activation of different modal boxes on a page is here. The data-target of the buttons of the two modal boxes is changed to data-target="#myModal_1"; the id of the second modal box is changed to id="myModal_1"; two different modal boxes can be opened separately. The same is true for adding multiple modal frames.
