My solution isvar result = new Bloodhound({ datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'), queryTokenizer: Bloodhound.tokenizers.whitespace, remote: { url: 'abc.com&qterm=#%QUERY', wildcard: '%QUERY', rateLimitWait: 300 , transport: function (opts, onSuccess, onError) { var url = opts.url.split("#")[0]; var query = opts.url.split("#")[1]; $.ajax({ url: url + query, type: "POST", success: onSuccess, error: onError, }); }, filter: function (data) { if (data) { var result = data.data.results.data; return $.map(result, function (object) { return { name: object.basicinfo.object_name, id: object.basicinfo.id }; }); } else { return {}; } } }, dupDetector: function (remoteMatch, localMatch) { return remoteMatch.id === localMatch.id; } }); function onSuccess(data) { } result.initialize(); $('input').typeahead(null, { hint: true, name: 'result', displayKey: 'name', source: result.ttAdapter(), templates: { empty: ['<div class="empty-message">', 'no results found', '</div>'].join('\n'), suggestion: function (data) { return '<p class="type-suggestion">' + data.name + '</p> \n\r'; } }, }) 这篇关于类型检索中出现重复记录的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
