Javascript - wie man in der Schleife nach Mismatch sucht?

Question

Ich mag zu finden, wenn es eine Diskrepanz von der Benutzereingabe gegen die vorhandenen Daten ist dann etwas tun:

var reset = false;  
var user = [ 
    { public_name: 'e', code_name: 'f' }, 
    { public_name: 'c', code_name: 'not match' }, 
    { public_name: 'a', code_name: 'b' } 
]; 

var server = [ 
    {"code_name":"b","public_name":"a"}, 
    {"code_name":"d","public_name":"c"}, 
    {"code_name":"f","public_name":"e"} 
] 

user.forEach(function(field, index) { 
    var matchingSpecies = server.find(function(item) { 
     if (item.code_name === field.code_name 
      && item.public_name === field.public_name) { 
      // matched so do nothing 
     } else { 
      // not match and stop looping 
      reset = true; 
     } 
    }); 
}); 

console.log(reset); 

aber das Ergebnis bekomme ich immer true obwohl es eine Übereinstimmung gibt.

irgendwelche Ideen?

Answer 1

Sie könnten Ihren Code wie folgt anpassen:

var reset = false;  
var user = [ 
    { public_name: 'e', code_name: 'f' }, 
    { public_name: 'c', code_name: 'not match' }, 
    { public_name: 'a', code_name: 'b' } 
]; 

var server = [ 
    {"code_name":"b","public_name":"a"}, 
    {"code_name":"d","public_name":"c"}, 
    {"code_name":"f","public_name":"e"} 
] 

user.forEach(function(field, index) { 
    var match = false; 
    server.find(function(item) { 
     if (item.code_name === field.code_name 
      && item.public_name === field.public_name) { 
      match = true; 
     } 
    }); 
    reset = reset || ! match; 
}); 

console.log(reset);

Sie so etwas wie dies versuchen:

Anmerkung: Ich habe eine Kopie der Original-user gemacht und aktualisiert es server passen beide Zustände zu zeigen, .

JSFiddle

function findMatching(array) { 
 
    var _reset = false; 
 
    array.forEach(function(field, index) { 
 
    var matchingSpecies = server.find(function(item) { 
 
     return item.code_name !== field.code_name && item.public_name === field.public_name 
 
    }); 
 
    _reset = matchingSpecies && Object.getOwnPropertyNames(matchingSpecies).length>0 || _reset 
 
    }); 
 
    return _reset; 
 
} 
 

 
var user=[{public_name:"e",code_name:"f"},{public_name:"c",code_name:"not matched"},{public_name:"a",code_name:"b"}], 
 
    user1=[{public_name:"e",code_name:"f"},{public_name:"c",code_name:"d"},{public_name:"a",code_name:"b"}], 
 
    server=[{code_name:"b",public_name:"a"},{code_name:"d",public_name:"c"},{code_name:"f",public_name:"e"}]; 
 

 
console.log(findMatching(user)); 
 
console.log(findMatching(user1));
