【问题描述】：

我想使用查询字符串从对象数组中进行模糊搜索。 搜索可以嵌套在搜索对象中，如下例所示；

var data = [ 
              
                "id":"1",
                "name":"Ali",
                "BOD":"29/10/2055",
                "type":"primary",
                "email":"[e-mail]",
                "mobile":"0100000000",
                "notes":["note1" ,"note2" ,"note3"]
              ,
               
                "id":"2",
                "name":"Tie",
                "BOD":"29/10/2055",
                "type":"primary",
                "email":"[e-mail]",
                "mobile":"0100000000",
                "notes":["note4" ,"note5" ,"note6"]
              
  ];


   function search(query)
     // search code go here
     
     

   // search examples
   search('.net'); //expected data[1]
   search('ali');  //expected data[0]
   search('0110'); //expected data[0],data[1]

【问题讨论】：

为什么'ali'会得到两个结果？

“模糊搜索”是什么意思？您希望query 与任何对象值匹配吗？

返回匹配的逻辑是什么？另见javascript fuzzy search that makes sense

@guest271314 这更符合我对模糊搜索的预期。

@NinaScholz 抱歉我现在修好了

【参考方案1】：

我做了一个简单的解决方案，它不是最理想的，但它有效。 这样做没有嵌套搜索的模糊搜索分数。

var data = [ 
              
                "id":"1",
                "name":"Ali",
                "BOD":"29/10/2055",
                "type":"primary",
                "email":null,
                "mobile":"010100000000",
                "notes":["note1" ,"note2.nett" ,"note3"]
              ,
               
                "id":"2",
                "name":"Tie",
                "BOD":"29/10/2055",
                "type":"primary",
                "email":"[e-mail]",
                "mobile":"0100000000",
                "notes":["note4" ,"note5" ,"note6"]
              
  ];

    /**
     * query: query string to match with
     * dataArray: data array variable, array or opject to search it
     **/
   function search(query,dataArray)
     // search code go here
     //console.log(query);
     var matched = [];
     //init null values
     if(!dataArray)dataArray=;
     if(!query)query='';
     dataArray.forEach(function(obj,index)
        for(var key in obj)
          if(!obj.hasOwnProperty(key) || !obj[key]) continue;
          if(obj[key].toString().indexOf(query) !== -1)
            
              matched.push(obj );
             
        
     );
     return matched ;      
     

   // search examples .
  console.log("found",search('.net',data).length);//expected data[0] data[1]
  console.log("found",search('Ali',data).length);//expected data[0]
  console.log("found",search('0116',data).length);//expected data[0],data[1]
