在 Jquery 中自行打开手风琴

Question

我有 bootstrap 手风琴。我需要以某种方式自动运行它。逐个打开标签。目前，我写了这个功能但它并不像我想要的那么顺利。也许有一个可用的库或其他东西。

var index = 5;
function foo (condition) {
// do stuff
if(index !== 5){
  index--;
}

$('#accordion').accordion()

let active = $('#accordion').accordion('option', 'active')
$('#accordion').accordion('option', 'active', active)

$('#accordion').accordion('option', 'active', active)

if (index < 10) {
  $('#accordion').accordion('option', 'active', active + 1)
  index++
} else {
    $('#accordion').accordion('option', 'active', active - 1)

}

setTimeout(foo, 2000)
console.log(index)

}

foo()

Answer 1

试试这个：

$(document).ready(function() {
  function foo(condition) {
    $('a[href="#collapse' + condition + '"]').trigger("click");
  }

  var length = $('.panel-heading').length;

  var j = 1;
  window.setInterval(function() {
    if (j > length) j = 1;

    foo(j++)
  }, 2000);
});
