如何使用Javascript更改模式中按钮的数据目标？

Question

我在模态中有一个按钮。当我按下按钮时，我希望该模式关闭，而另一个模式打开。但是，每次打开的模式都不相同，因此每次按下按钮时的数据目标都需要更改。

为了关闭模式，我在按钮的属性中添加了data-dismiss="modal"。

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

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

我尝试这样做，但是没有用：

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

Answer 1

更新：此代码，每次都会打开一个随机模态并关闭另一个模态。

 $('.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;
}
