如何在加减按钮单击时显示显示/隐藏表格

Question

//JQuery Script one 
 $(document).ready(function(){
            $('.table1').on('click',function(){

                $('.table1shw').show();

            });
            
        });
        
        
//I try second method too but unable to display. 
document.getElementById('sp1').addEventListener("click", function() {
  showTable('t1');
});





function showTable(table) {
  var tables = ['t1'];
  for (var i = 0; i < 4; i++) {
    document.getElementById(tables[i]).style.display = "none";
  }
  document.getElementById(table).style.display = "block";

}

.table-hide{
    display: none;
}

您好，谢谢！一旦我点击加号按钮，我试图显示完整的表格，一旦我点击减号按钮，同一个表格就会隐藏。我会以两种不同的方式完成此操作，但我对此没有任何运气。所以我对如何解决感到沮丧，你能告诉我我做错了什么以及在哪里。请帮忙。

您没有在正确的元素上调用 .show()。

我已经更新了你的代码 -

$(document).ready(function() {
  $("#t1").hide(); // hide table by default
  $('#sp1').on('click', function() {
    $("#t1").show();
  });
  $('#close').on('click', function() {
    $("#t1").hide();
  });
});

          </td>
        </tr>
      </tbody>
    </table>
  </div>
</div>

我的改变是 -

$("#t1").hide(); - 默认隐藏表格，使用t1，这是表格的id

在sp1 上添加点击处理程序，这是加号按钮的 id 并在事件中显示表格 -

$('#sp1').on('click', function() {
     $("#t1").show();
});

最后在其 id close 的关闭按钮上添加点击处理程序

$('#close').on('click', function() {
     $("#t1").hide();
});
