    }
  }
]

the concept is ... if i select a policestation and crime number,then will get details based on that from API...

Here is the working code that allows multiple filtering of data from the response.The result is shown in the console.

class TestJS extends React.Component {
  constructor(props) {
      super(props);
      this.state={
          value:'',
          value2:'',
          resultFound : false,
          filteredData : ""
      };
      this.handleChange=this.handleChange.bind(this);
      this.crimeChange=this.crimeChange.bind(this);
      this.search=this.search.bind(this);
      this.multiFilter=this.multiFilter.bind(this);
  }

   multiFilter(array, filters) {
      const filterKeys = Object.keys(filters);
      // filters all elements passing the criteria
      return array.filter((item) => {
          // dynamically validate all filter criteria
          return filterKeys.every(key => !!~filters[key].indexOf(item[key]));
      });
  }

  handleChange(event){
      this.setState({value:event.target.value});
  }

  crimeChange(event) {
      this.setState({value2:event.target.value});
  }
  search(){
      let _this = this;
      let {value, value2 } =this.state;
      const url=`https://api.myjson.com/bins/e69i9/?i=${value}&q=${value2}`;

      fetch(url,{
          method:'GET'
      }).then(response => response.json())
          .then(function(data){
              console.log(data, value, value2);
              let filters = {
                  "police station" : [value],
                  "crime number" : [parseInt(value2)]
              };
              let  filtered = _this.multiFilter(data, filters);
              console.log(filtered);
              if(filtered.length <= 0){
                _this.setState({resultFound : false})
              }
              else{
                _this.setState({filteredData : filtered, resultFound : true})
              }
          });
  }

  render() {
      return (
          
              
                  
                      

                          
                      
                      
                          
                              
                              
                      

                      
                          
                      
                      {!this.state.resultFound ?  No Data Found!! : 
                        JSON.stringify(this.state.filteredData)}
                  
              
          
      )
  }
}
export default TestJS;
