Question

我在我的应用程序中使用Bootstrap Typeahead插件，这是我的代码（这是一个例子）。我正在寻找一种方法来验证用户的选择（基本上如果输入与任何结果不匹配 - ＆gt;清空模糊框）。结果必须匹配。我到处搜索，找不到东西。非常感谢您的帮助。

    $('#search').typeahead({
        source: function (query, process) {
            var states = [];
            var map = {};

            var data = [
                { "stateCode": "CA", "stateName": "California" },
                { "stateCode": "AZ", "stateName": "Arizona" },
                { "stateCode": "NY", "stateName": "New York" },
                { "stateCode": "NV", "stateName": "Nevada" },
                { "stateCode": "OH", "stateName": "Ohio" }
            ];

            $.each(data, function (i, state) {
                map[state.stateName] = state;
                states.push(state.stateName);
            });

            process(states);
        }
    });

如果您提取数据，状态和地图，则可以在.blur函数中使用它们进行查找：

 var data = [
            { "stateCode": "CA", "stateName": "California" },
            { "stateCode": "AZ", "stateName": "Arizona" },
            { "stateCode": "NY", "stateName": "New York" },
            { "stateCode": "NV", "stateName": "Nevada" },
            { "stateCode": "OH", "stateName": "Ohio" }
        ];
 var states = [];
 var map = {};

 $.each(data, function (i, state) {
    map[state.stateName] = state;
    states.push(state.stateName);
 });

 $('#search').typeahead({
    source: function (query, process) {
        process(states);
    }
}).blur(function(){
    if(states[$(this).val()] == null) {
      $('#search').val('');
    }
});

来自mccannf的解决方案有效，但就我的情况而言，模糊事件为if(parents.indexOf($(this).val()) === -1) {。
