数组元素和对象属性的比较返回false

Question

我想输出哪些数组元素等于对象属性。

数组和对象是这样的：

var groupProperties = { 
    "processors": ["producent: ","model-line: ","model: ","freq: ","cores: ","threads: ","quantity: ","netto_price: "], 

    "graphics": ["producent: ","model_line: ","model: ","vram: ","directx: ","quantity: ","netto_price: "], 

    "motherboards": ["producent: ","model_line: ","model: ","chipset: ","quantity: ","netto_price: "] 
}; 

var groups = [ 
    PROCESSORS 
    ,AMD|ATHLON|7750|2.6|6|2|7|250.00 
    INTEL|i7|720QM|2.8|4|8|5|450.25 
    INTEL|i5|4570|3.2|4|4|4|345.50 
    ,GRAPHICS 
    ,AMD|RADEON|7790|1GB|11|3|300.90 
    NVIDIA|GEFORCE|8800GTS|512MB|10|1|150.99 
    ,MOTHERBOARDS 
    ,MSI|GAMING|GD-65|Z87|5|510.30 
    ASUS|RAMPAGE|MAXIMUS-VII|Z87|6|890.99 
    ASUS|UNKNOWN|P5KC|P35|1|50.00 
]; 

我的功能，这是不行的（if语句返回false，不知道为什么）：

for (var index in groups) { 
    for(var property in groupProperties) { 
     console.log('PROPS '+property); 
     console.log("second loop \n"); 
     console.log("ARRAY "+groups[index]); 
     if(groups[index] === property.toUpperCase()) { 
      console.log("third loop \n"); 
      console.log("Array elements equal with object properties "+groups[index]); 
     } 
    }    
} 

输出应成为：'处理器'，'图形'，'主板'。

@edit 我发现的东西是错误的组阵列，原因在控制台，它看起来是这样的：http://imgur.com/FH7Geu8

所以我给与操作上的所有原产阵列整个代码。我希望有人可以帮助与固定起来：

// var content <= there is text loaded from '.txt' file 

      var splittedRows= content.split('\n'); 
      console.log("Splitted: \n"+ splittedRows); 

      var groups = []; 
      var inner = 0; 

      for (index in splittedRows) 
      { 
       if (splittedRows[index].indexOf('GRP') == 0) 
       { 
        groups[index] = splittedRows[index].slice('PRD|'.length); 
        inner = Number(index) + 1; 
         console.log('inner '+inner); 
        continue; 
       } 
       if (groups[inner] === undefined) 
       { 
        groups[inner] = splittedRows[index].slice('PRD|'.length); 
        continue; 
       } 
       groups[inner] += splittedRows[index].slice('PRD|'.length); 
      } 
      console.log(groups); 

      for(i=0; i<groups.length; i++) 
      { 

       if (!groups[i]) 
       { 
        groups.splice(i,1); 
        i--; 
       } 
        //console.log("Moved "+groups[i]); 
      } 

而且从那里文本装起来来源：

GRP | PROCESSORS珠三角| AMD | ATHLON | 7750 | 2.6 | 6 | 2 | 7 | 250.00 PRD | INTEL | i7 | 720QM | 2.8 | 4 | 8 | 5 | 450.25 PRD | INTEL | i5 | 4570 | 3.2 | 4 | 4 | 4 | 345.50 GRP | GRAPHICS PRD | AMD | RADEON | 7790 | 1GB | | | 3 | 300.90 PRD | NVIDIA | GEFORCE | 8800GTS | 512MB | 10 | 1 | 150.99 GRP |主板 PRD | MSI | GAMING | GD-65 | Z87 | 5 | 510.30 PRD |华硕| RAMPAGE | MAXIMUS- VII | Z87 | 6 | 890.99 PRD |华硕| UNKNOWN | P5KC | P 35 | 1 | 50.00

@ EDIT2

我通过splice'ingundefined元件和slice'ing '\ R' 从数组元素煤焦出固定组阵列。 现在所有的作品 - 我可以比较数组元素与对象的属性。

您可以轻松地acomplish此使用Array.prototype.filter和Object.prototype.hasOwnProperty：

var groupProperties = { 
 
    "processors": ["producent: ","model-line: ","model: ","freq: ","cores: ","threads: ","quantity: ","netto_price: "], 
 

 
    "graphics": ["producent: ","model_line: ","model: ","vram: ","directx: ","quantity: ","netto_price: "], 
 

 
    "motherboards": ["producent: ","model_line: ","model: ","chipset: ","quantity: ","netto_price: "] 
 
}; 
 

 
var groups = [ 
 
    "PROCESSORS", 
 
    "AMD|ATHLON|7750|2.6|6|2|7|250.00", 
 
    "INTEL|i7|720QM|2.8|4|8|5|450.25", 
 
    "INTEL|i5|4570|3.2|4|4|4|345.50", 
 
    "GRAPHICS", 
 
    "AMD|RADEON|7790|1GB|11|3|300.90", 
 
    "NVIDIA|GEFORCE|8800GTS|512MB|10|1|150.99", 
 
    "MOTHERBOARDS", 
 
    "MSI|GAMING|GD-65|Z87|5|510.30", 
 
    "ASUS|RAMPAGE|MAXIMUS-VII|Z87|6|890.99", 
 
    "ASUS|UNKNOWN|P5KC|P35|1|50.00" 
 
]; 
 

 
var propGroups = groups.filter(function(group) { 
 
    return groupProperties.hasOwnProperty(group.toLowerCase()); 
 
}); 
 

 
console.log(propGroups);

你需要用这些阵列条目在引号，像这样：

var groups = [ 
    "PROCESSORS", 
    "AMD|ATHLON|7750|2.6|6|2|7|250.00", 
    "INTEL|i7|720QM|2.8|4|8|5|450.25", 
    "INTEL|i5|4570|3.2|4|4|4|345.50", 
    "GRAPHICS", 
    "AMD|RADEON|7790|1GB|11|3|300.90", 
    "NVIDIA|GEFORCE|8800GTS|512MB|10|1|150.99", 
    "MOTHERBOARDS", 
    "MSI|GAMING|GD-65|Z87|5|510.30", 
    "ASUS|RAMPAGE|MAXIMUS-VII|Z87|6|890.99", 
    "ASUS|UNKNOWN|P5KC|P35|1|50.00" 
];
