javascript - 如何使用 Javascript 更改模式中按钮的数据目标？

Question

我在模式中有一个按钮。当我按下按钮时，我希望关闭该模式，并打开另一个模式。但是，每次打开的模态都不相同，因此每次按下时按钮上的数据目标都需要更改。

为了关闭模式，我在按钮的属性中设置了 data-dismiss="modal"。

我有三个 ID 为 1,2,3 的模态框。我想使用随机 Javascript 函数来选择打开哪个

var randomnumber = num.toString(Math.floor(Math.random() * (3 - 1 + 1)) + 1);

我试过这样做，但没有成功:

$('#button').click(function() {
$(randomnumber).modal('show');

Answer 1

更新:这段代码，每次都会打开一个随机模式并关闭另一个。

 $('.fade').hide();
$('.btn-info').click(function()
{
var randomnumber =Math.floor(Math.random() * 3) + 1;
  $('.fade').hide();
  $('#m'+randomnumber).show(10);
  alert("modal" + randomnumber)
});


$('#btn3').click(function()
{
   $('.fade').hide();
  $('#myModal').show();
 
});

$('.close').click(function()
{
   $('.fade').hide();

});

.fade
{
display:none;
}
