jquery - Select2 在外部单击时不会关闭选择框（closeOnSelect=false）

Question

JSFiddle：http: //jsfiddle.net/xpvt214o/776660/

When the choice box is open, if you try clicking anywhere outside on the level of the choice box , it doesn't get closed. 但是，如果您在当前选择线的级别上单击外部，则它确实会关闭。

执行任何外部单击时，包括在选择框级别上，如何强制关闭 Select2 选择框？

PS我正在使用该closeOnSelect: false选项在选择过程中保持选择框始终打开-但它仍应在外部单击时关闭，

$('#dropdown').select2({
    closeOnSelect: false
});

另一个类似的问题-当 closeonselect 为 false 时关闭 select2 on click away

不知道是什么导致了问题，但是将其添加到您的 CSS 中会“修复”它

选择 2 问题 4939

html,
body{
  height: 100%;
}

更新代码

/* Scroll CurrSel SPAN to bottom on every Select2 Select event */
$('#dropdown').on("select2:selecting", function(e) {
  var currselspan = $('#dropdown').next().find('.select2-selection--multiple').first();
  console.log('scrollTop = ' + $(currselspan).scrollTop() + ' scrollHeight = ' + $(currselspan).prop('scrollHeight'));
  $(currselspan).scrollTop($(currselspan).prop('scrollHeight'));
});



$('#dropdown').select2({
  closeOnSelect: false,
});

.select2-selection--multiple {
  height: 2rem;
  max-height: 2rem;
  overflow: auto;
}
