Question

我想在表格中生成从1到70的数字，每行只包含5个数字。我已经生成了这个，但我不知道如何在第五个</td>之后关闭表格行。我还希望它生成<a>标记。请帮帮我。

flag = false;
for (var i = 1; i <= 15; i++) {
  if (!flag) {
    $("tbody").append("<tr>")
    flag = true;
  }

  $('tr').append('<td><a data-index=' + i + '>' + i + '</a></td>');

  if (i % 5 == 0) {
    $("td:nth-child(5n)").insertAfter('</tr>');
    flag = false;
  }
}

Answer 1

我建议你使用这样的jQuery追加代码：

$('tbody').append(
   $('<tr>').append(
     $('td').append(
       $('a').attr('data-index', i)
      )
    )
 )

jQuery会自动关闭标签。

这是一个小的逻辑变化。想法是在变量中构建所有td标记，当您将数字乘以5时，将其附加到tbody并将其附加到tr

＆＃13;

var $tableBody = $('tbody'); // use a Id selector here
var rowHTML = '';

for (var i = 1; i <= 15; i++) {
  rowHTML += '<td><a data-index=' + i + '>' + i + '</a></td>';

  if (i % 5 == 0) {
    $tableBody.append('<tr>' + rowHTML + '</tr>');
    rowHTML = '';
  }
}
