Bootstrap tokenfield 和 Twitter typeahead 下拉菜单没有样式

Question

我有一个类似于 this one but I'm using both Tokenfield v0.12.1 and Twitter typeahead v0.11.1 的问题。当我开始输入并出现建议时，它们没有样式。它显示为纯文本（如果我点击建议，它会添加到输入字段）。例如，如果我键入 "re"，则会出现 "red" 的建议，但它显示为无样式，如下所示：

{"_query":"re","value":"red","label":"red"}

我的CSS个源文件

<link href="~/Content/bootstrap-tokenfield/tokenfield-typeahead.css" rel="stylesheet" />
<link href="~/Content/bootstrap-tokenfield/bootstrap-tokenfield.css" rel="stylesheet" />

我的 JS 源文件

<script src="~/Scripts/bootstrap-tokenfield.min.js"></script>
<script src="~/Scripts/typeahead.bundle.min.js"></script>
<script>
$(document).ready(function () {
    var engine = new Bloodhound({
        local: [{ value: 'red' }, { value: 'blue' }, { value: 'green' }, { value: 'yellow' }, { value: 'violet' }, { value: 'brown' }, { value: 'purple' }, { value: 'black' }, { value: 'white' }],
        datumTokenizer: function (d) {
            return Bloodhound.tokenizers.whitespace(d.value);
        },
        queryTokenizer: Bloodhound.tokenizers.whitespace
    });

    engine.initialize();

    $('#tokenfield-typeahead').tokenfield({
        typeahead: [null, {
            source: engine.ttAdapter()
        }]
    });
});
</script>

我的HTML

<input type="text" class="typeahead form-control" id="tokenfield-typeahead" />

我的代码片段如下所示。请帮助我做错了什么？

$(document).ready(function() {
  var engine = new Bloodhound({
    local: [{
      value: 'red'
    }, {
      value: 'blue'
    }, {
      value: 'green'
    }, {
      value: 'yellow'
    }, {
      value: 'violet'
    }, {
      value: 'brown'
    }, {
      value: 'purple'
    }, {
      value: 'black'
    }, {
      value: 'white'
    }],
    datumTokenizer: function(d) {
      return Bloodhound.tokenizers.whitespace(d.value);
    },
    queryTokenizer: Bloodhound.tokenizers.whitespace
  });

  engine.initialize();

  $('#tokenfield-typeahead').tokenfield({
    typeahead: [null, {
      source: engine.ttAdapter()
    }]
  });
});

For example, if I type "re", the suggestion for "red" appears but it shows unstyled as follows:

{"_query":"re","value":"red"...

为了避免您需要将 displayKey 选项添加到您的 tokenfield:

$('#tokenfield-typeahead').tokenfield({
    typeahead: [null, {
        source: engine.ttAdapter(),
        displayKey: 'value'
    }]
});

$(document).ready(function() {
    var engine = new Bloodhound({
        local: [{
            value: 'red'
        }, {
            value: 'blue'
        }, {
            value: 'green'
        }, {
            value: 'yellow'
        }, {
            value: 'violet'
        }, {
            value: 'brown'
        }, {
            value: 'purple'
        }, {
            value: 'black'
        }, {
            value: 'white'
        }],
        datumTokenizer: function(d) {
            return Bloodhound.tokenizers.whitespace(d.value);
        },
        queryTokenizer: Bloodhound.tokenizers.whitespace
    });

    engine.initialize();

    $('#tokenfield-typeahead').tokenfield({
        typeahead: [null, {
            source: engine.ttAdapter(),
            displayKey: 'value'
        }]
    });
});
