function hellofunction(arrObj, val){ 
    $.each(arrObj,function(k,v){ 
     if(arrObj[k]["EMP_NO"] == val){ 
      return arrObj[k]["EMP_NAME"]; 
     } 
    }); 
} 

// Call function 
var kaka = hellofunction(data["OUT_REC"], "roth_kakvey"); 

console.log("=====:"+kaka); 

出力= "underfine"

Answer 1

$.each(arrObj,function(k,v){ 
     if(arrObj[k]["EMP_NO"] == val){ 
      return arrObj[k]["EMP_NAME"]; 
      // does not return from the hellofunction. 
      // Instead it returns from the function(k,v) i.e. the callback to each 
     } 
    }); 

：

function hellofunction(arrObj, val){ 
    var empName; 
    $.each(arrObj,function(k,v){ 
     if(arrObj[k]["EMP_NO"] == val){ 
      empName = arrObj[k]["EMP_NAME"]; 
      return false; //returning from callback, works like break statement 
     } 
    }); 
    return empName; 
}
