标记它是一个轻量级的jQuery插件，用于将普通HTML列表转换为标记管理器，允许与任何输入字段通信，并支持自动完成/建议（需要jQuery UI）。

参见：

• jQuery和Vanilla JavaScript中的10个最佳标签输入插件

如何使用它:

1.在html页面上加载jQuery库和jQuery标记it插件的文件。

<!-- jQuery is required -->
<script src="/path/to/cdn/jquery.min.js"></script>

<!-- jQuery Tag-It Plugin -->
<link href="css/jquery.tagit.css" rel="stylesheet" />
<script src="js/tag-it.min.js"></script>

2.该插件需要jQuery UI库来实现自动完成功能。

<script src="/path/to/cdn/jquery-ui.min.js"></script>

3.标签管理器的基本HTML结构。

<form>
  <input name="tags" id="demo-input" value="Armenia, Germany" disabled="true">
  <ul id="demo-list"></ul>
  <input type="submit" value="Submit">
</form>

4.为标签管理器创建一个建议值的数组。

var country_list = ["Afghanistan","Albania","Algeria"];

5.使用一些选项初始化标签管理器。

$('#demo-list').tagit({
  availableTags: country_list,
  // This will make Tag-it submit a single form value, as a comma-delimited field.
  singleField: true,
  singleFieldNode: $('#demo-input')
});

6.更多具有默认值的配置选项。

$('#demo-list').tagit({

  allowDuplicates: false,
  caseSensitive: true,
  fieldName: "tags",
  placeholderText: null,
  readOnly: false,

  // Require confirmation to remove tags
  removeConfirmation: false,

  // Max number of tags allowed (null for unlimited)
  tagLimit: null,

  // Used for autocomplete
  availableTags: [],

  // Use to override or add any options to the autocomplete widget
  autocomplete: {},

  // Shows autocomplete before the user even types anything
  showAutocompleteOnFocus: false,

  // When enabled, quotes are unneccesary for inputting multi-word tags
  allowSpaces: false,

  // Use a single hidden field for the form, rather than one per tag. 
  // It will delimit tags in the field with singleFieldDelimiter.
  singleField: false,
  singleFieldDelimiter: ",",

  // Set this to an input DOM node to use an existing form field.
  singleFieldNode: null,

  // Whether to animate tag removals or not
  animate: true,

  // Optionally set a tabindex attribute on the input that gets
  tabIndex: null,
  
});

7.提供回调功能。

$('#demo-list').tagit({
  beforeTagAdded: null,
  afterTagAdded: null,
  beforeTagRemoved: null,
  afterTagRemoved: null,
  onTagClicked: null,
  onTagLimitExceeded: null,
});

8.API方法。

// Returns an array of the text values of all the tags
$("#demo-list").tagit("assignedTags");

// Adds new tag
$("#demo-list").createTag(tagLabel, additionalClass);

// Called before tag is created
$("#demo-list").preprocessTag(function, Callback);

// Finds the tag with the label tagLabel and removes it.
$("#demo-list").removeTagByLabel(tagLabel, animate);

// removes all tags
$("#demo-list").tagit("removeAll");
