Question

我将引导标签输入（对象作为标签-https://bootstrap-tagsinput.github.io/bootstrap-tagsinput/examples/）用于标签输入。可以将Objects用作自动完成建议的标签。

但是我也尝试激活免费输入。因此，如果标签不在自动建议列表中，则可以添加新标签。

这是我的代码：


var tags = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('text'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
   prefetch:  {
        ttl: 1,
        url:'[Json File Path]'
        }
});
tags.initialize();

var elt = $('input#tags');

elt.tagsinput({
  tagClass: 'badge badge-primary',
   itemValue: function(item) {
    return item.id;
  },
  itemText: 'text',
  freeInput: true,
   typeaheadjs: {
    name: 'tags',
    displayKey: 'text',
    source: tags.ttAdapter()
  } 
});

Json示例：

[{"id":15,"text":"money"},{"id":14,"text":"startup"},{"id":13,"text":"inspiration"},{"id":12,"text":"success"},{"id":11,"text":"challenge"}]

带有对象的Bootstrap标签输入作为标签标头免费输入不起作用
