搜索并获得有限的搜索结果

Question

我有一个JSON文件，它看起来像这样

[{ 
    "id": "2", 
    "word": "Aam", 
    "type": "n.", 
    "descr": " A Dutch and German measure of liquids, varying in different cities, being at Amsterdam about 41 wine gallons, at Antwerp 36 1\/2, at Hamburg 38 1\/4.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aam" 
}, { 
    "id": "3", 
    "word": "Aard-vark", 
    "type": "n.", 
    "descr": " An edentate mammal, of the genus Orycteropus, somewhat resembling a pig, common in some parts of Southern Africa. It burrows in the ground, and feeds entirely on ants, which it catches with its long, slimy tongue.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}, { 
    "id": "4", 
    "word": "Aard-wolf", 
    "type": "n.", 
    "descr": " A carnivorous quadruped (Proteles Lalandii), of South Africa, resembling the fox and hyena. See Proteles.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}, { 
    "id": "5", 
    "word": "Aaronic", 
    "type": "a.", 
    "descr": " Alt. of Aaronical", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}, { 
    "id": "6", 
    "word": "Aaronical", 
    "type": "a.", 
    "descr": " Pertaining to Aaron, the first high priest of the Jews.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}, { 
    "id": "7", 
    "word": "Aarons rod", 
    "type": "", 
    "descr": " A rod with one serpent twined around it, thus differing from the caduceus of Mercury, which has two.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}, { 
    "id": "8", 
    "word": "Aarons rod", 
    "type": "", 
    "descr": " A plant with a tall flowering stem; esp. the great mullein, or hag-taper, and the golden-rod.", 
    "track": "a", 
    "track_2": "Aa", 
    "track_3": "Aar" 
}] 

我想获得前2或3的结果的其中一句话=“AA”，track_2 =“AA”， track_3 =“aar”..我该怎么做？

我需要
1.查询JSON中通过什么字符串 2.获取有限的结果 3.我想2-3的条件

我想要在JSON文件中搜索这

$(window).load(function() { 

    $('#search').keyup(function() { 
     var searchField = $('#search').val(); 

     $.getJSON('files/aa.json', function(data) { 

      var jsonArrr = data; 
      var matchMe = new RegExp('^' + searchField, 'i'); 
      var matches = []; 

      for (var i in jsonArrr) { 
       if (jsonArrr[i].word.search(matchMe) > -1) { 
        matches.push({ 
         'id': jsonArrr[i].word, 
         'word': jsonArrr[i].word 
        }); 
       } 
      } 

      for (var i in matches) { 
       console.log(matches[i].word); 
      } 
     }); 
    }); 
}); 

有没有办法让我需要扩大一些代码？

Answer 1

添加几行代码在这个部分 -

var matches = []; 

for (var i in jsonArrr) { 

    if (jsonArrr[i].word.search(matchMe) > -1 && jsonArrr[i].type.search(matchType) > -1) { // define matchType for the type keyword 

      matches.push({'id': jsonArrr[i].word , 'word': jsonArrr[i].word}); 

    } 

if(matches.length == 2) { // replace 2 with your number of results - 1 
break; 
} 

}
