How to activate the Bootstrap modal-backdrop?

Question

Answer 1

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('
').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {
  var bd = $('
');
  bd.appendTo(document.body);
  setTimeout(function() {
    bd.remove();
  }, 2000);
});

Click the button to get the backdrop for two seconds.
