我想把這個php函數轉換成javascript函數

Question

我有一個PHP函數來從數據庫檢索到的數據創建一個地址。我想要使​​用相同的功能來創建一個JavaScript函數來執行相同的操作。它所做的是採取領域，如果它是空的，它什麼都不做，但如果有數據，它會附加「，」一個逗號和空格。

$parts = array(
      $club['clubAdd1'], 
      $club['clubAdd2'], 
      $club['clubCity'], 
      $club['clubCounty'], 
      $club['clubPostcode'], 
     ); 

$address = array(); 

foreach ($parts as $part){ 
    if ('' != $part){ 
     $address[] = $part; 
    } 
} 

$address = implode(', ', $address); 

我的當前的嘗試是每次被調用的函數的KEYUP上表單字段預成形（測試目的）

function autoAddress(){ 
var address = ""; 
var address1 = document.address.address1.value; 
var address2 = document.address.address2.value; 
var city = document.address.city.value; 
var county = document.address.county.value; 
var postcode = document.address.postcode.value; 

var parts = new array[ 
     address1, 
     address2, 
     city, 
     county, 
     postcode 
     ]; 
var testAddress = new array(); 
foreach(parts as part){ 
    if ('' != part){ 
    testAddress[] = part; 
    } 
} 
testAddress = array.join(', ', testAddress); 
alert(testAddress); 

}

Answer 1

var parts = [ 
      club['clubAdd1'], 
      club['clubAdd2'], 
      club['clubCity'], 
      club['clubCounty'], 
      club['clubPostcode'] 
     ]; 

var address = []; 

for (var i=0; i<=parts.length; i++){ 
    if (parts[i]){ 
     address.push(parts[i]); 
    } 
} 

var joined = address.join(', ');
