Javascript Js只返回表的第一行

我有以下资料：

  function builTable(){
    for(i = 0; i< source.Products.length; i++){

      var sourceProducts = source.Products[i];
          row = '<tr><td>sth</td><td>';
          row += sourceProducts.Product;
          row += '</td><td>';
          row += sourceProducts.Bookings + '</td><td>';
          row += sourceProducts.Percentage + '%' + '</td><td>';
          row += sourceProducts.Transactions + '</td></tr>';

          return row;

    }

  }

  function generateTable(){
    $('table').append(builTable());
  }

  $(document).ready(function(){

    generateTable();

  });

  function builTable(){
    for(i = 0; i< source.Products.length; i++){

      var sourceProducts = source.Products[i];
          row = '<tr><td>sth</td><td>';
          row += sourceProducts.Product;
          row += '</td><td>';
          row += sourceProducts.Bookings + '</td><td>';
          row += sourceProducts.Percentage + '%' + '</td><td>';
          row += sourceProducts.Transactions + '</td></tr>';

       $('table').append(row);

    }


  }

  $(document).ready(function(){

    builTable();

  });

有什么帮助吗？

函数内置（）{
function builTable(){
    var table = "";

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

      var sourceProducts = source.Products[i],
          row = '<tr><td>sth</td><td>';

      row += sourceProducts.Product;
      row += '</td><td>';
      row += sourceProducts.Bookings + '</td><td>';
      row += sourceProducts.Percentage + '%' + '</td><td>';
      row += sourceProducts.Transactions + '</td></tr>';

      table += row;

    }

    return table;
  }

  function generateTable(){
    $('table').append(builTable());
  }

  $(document).ready(function(){

    generateTable();

  });

var表=”；
对于（i=0；i

这是因为每次循环再次开始时，

行

都会重置

function builTable(){
    for(i = 0; i< source.Products.length; i++){

      var sourceProducts = source.Products[i];

          // here is the culprit
          row = '<tr><td>sth</td><td>';


          row += sourceProducts.Product;
          row += '</td><td>';
          row += sourceProducts.Bookings + '</td><td>';
          row += sourceProducts.Percentage + '%' + '</td><td>';
          row += sourceProducts.Transactions + '</td></tr>';

          return row;

    }

  }

函数可构建（）{
对于（i=0；i

function builTable(){
    for(i = 0; i< source.Products.length; i++){

      var sourceProducts = source.Products[i];

          // here is the culprit
          row = '<tr><td>sth</td><td>';


          row += sourceProducts.Product;
          row += '</td><td>';
          row += sourceProducts.Bookings + '</td><td>';
          row += sourceProducts.Percentage + '%' + '</td><td>';
          row += sourceProducts.Transactions + '</td></tr>';

          return row;

    }

  }
