我正在嘗試將此php函數轉換為javascript函數

Question

我有一個PHP函數，用於從數據庫檢索的數據中創建地址。 我想使用相同的功能來制作將執行相同操作的JavaScript函數。 它的作用是獲取該字段，如果為空，則不執行任何操作，但如果有數據，則將在逗號后加上“，”。

$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);

我當前的嘗試是每次在窗體字段上執行加鍵時都會調用該函數（僅用於測試目的）

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(', ');
