在bootstrap模式打开时调用一个函数

$( "#code" ).on('shown', function(){
    alert("I want this to appear after the modal has opened!");
});

$('#code').on('shown.bs.modal', function (e) {
  // do something...
})

$(window).on('shown.bs.modal', function() { 
    $('#code').modal('show');
    alert('shown');
});

$(window).on('hidden.bs.modal', function() { 
    $('#code').modal('hide');
    alert('hidden');
});

$('#my-modal').on('shown', function(){
  // code here
});
