Bootstrap tagsinput标签输入框插件 jQuery tags input plugin based on Twitter Bootstrap

基本示例

在输入框中添加data-role="tagsinput"属性,输入框的值会自动转换为标签。


				
<input type="text" value="Amsterdam,Washington,Sydney,Beijing,Cairo" data-role="tagsinput" >	
				
			
方法 返回值
$("select").val() "Amsterdam,Washington,Sydney,Beijing,Cairo"
$("select").tagsinput('items') ["Amsterdam","Washington","Sydney","Beijing"]

通过select元素来制作标签

通过<select multiple />元可以将下拉框中的所有option转换为标签。


				
<select multiple data-role="tagsinput">
	<option value="Amsterdam">Amsterdam</option>
	<option value="Washington">Washington</option>
	<option value="Sydney">Sydney</option>
	<option value="Beijing">Beijing</option>
	<option value="Cairo">Cairo</option>
</select>
				
			
方法 返回值
$("select").val() ["Amsterdam","Washington","Sydney","Beijing","Cairo"]
$("select").tagsinput('items') ["Amsterdam","Washington","Sydney","Beijing"]

与typeahead.js结合使用

该插件可以和typeahead.js结合使用,在输入标签时获取预定义的提示标签信息。示例需要在服务器环境下才能调用json数据。


				
<input type="text" value="Amsterdam,Washington" data-role="tagsinput" />
<script>
var citynames = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('name'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  prefetch: {
    url: 'assets/citynames.json',
    filter: function(list) {
      return $.map(list, function(cityname) {
        return { name: cityname }; });
    }
  }
});
citynames.initialize();

$('input').tagsinput({
  typeaheadjs: {
    name: 'citynames',
    displayKey: 'name',
    valueKey: 'name',
    source: citynames.ttAdapter()
  }
});
</script>	
				
			
方法 返回值
$("select").val() "Amsterdam,Washington"
$("select").tagsinput('items') ["Amsterdam","Washington"]

使用对象作为标签

除了使用字符串作为标签之外,你还可以使用对象作为标签。这样做的好处是你在获取标签值的时候,可以获取到该对象的id值。示例需要在服务器环境下才能调用json数据。


				
<input type="text" />
<script>
var cities = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('text'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  prefetch: 'assets/cities.json'
});
cities.initialize();

var elt = $('input');
elt.tagsinput({
  itemValue: 'value',
  itemText: 'text',
  typeaheadjs: {
    name: 'cities',
    displayKey: 'text',
    source: cities.ttAdapter()
  }
});
elt.tagsinput('add', { "value": 1 , "text": "Amsterdam"   , "continent": "Europe"    });
elt.tagsinput('add', { "value": 4 , "text": "Washington"  , "continent": "America"   });
elt.tagsinput('add', { "value": 7 , "text": "Sydney"      , "continent": "Australia" });
elt.tagsinput('add', { "value": 10, "text": "Beijing"     , "continent": "Asia"      });
elt.tagsinput('add', { "value": 13, "text": "Cairo"       , "continent": "Africa"    });
</script>
				
			
方法 返回值
$("select").val() "1,4,7,10,13"
$("select").tagsinput('items') [{"value":1,"text":"Amsterdam","continent":"Europe"},{"value":4,"text":"Washington","continent":"America"},{"value":7,"text":"Sydney","continent":"Australia"},{"value":10,"text":"Beijing","continent":"Asia"},{"value":13,"text":"Cairo","continent":"Africa"}]

情景类标签

可以通过颜色来区分不同情景的标签。


				
<input type="text" />
<script>
var cities = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('text'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  prefetch: 'assets/cities.json'
});
cities.initialize();

var elt = $('input');
elt.tagsinput({
  tagClass: function(item) {
    switch (item.continent) {
      case 'Europe'   : return 'label label-primary';
      case 'America'  : return 'label label-danger label-important';
      case 'Australia': return 'label label-success';
      case 'Africa'   : return 'label label-default';
      case 'Asia'     : return 'label label-warning';
    }
  },
  itemValue: 'value',
  itemText: 'text',
  typeaheadjs: {
    name: 'cities',
    displayKey: 'text',
    source: cities.ttAdapter()
  }
});
elt.tagsinput('add', { "value": 1 , "text": "Amsterdam"   , "continent": "Europe"    });
elt.tagsinput('add', { "value": 4 , "text": "Washington"  , "continent": "America"   });
elt.tagsinput('add', { "value": 7 , "text": "Sydney"      , "continent": "Australia" });
elt.tagsinput('add', { "value": 10, "text": "Beijing"     , "continent": "Asia"      });
elt.tagsinput('add', { "value": 13, "text": "Cairo"       , "continent": "Africa"    });
</script>
				
			
方法 返回值
$("select").val() "1,4,7,10,13"
$("select").tagsinput('items') [{"value":1,"text":"Amsterdam","continent":"Europe"},{"value":4,"text":"Washington","continent":"America"},{"value":7,"text":"Sydney","continent":"Australia"},{"value":10,"text":"Beijing","continent":"Asia"},{"value":13,"text":"Cairo","continent":"Africa"}]
