嗨，目前我正在使用两个按钮加号和减号，只是我需要一次显示一个按钮。当加号按钮单击隐藏表将显示，减号按钮应该出现，加号按钮是隐藏的。减号按钮也一样。更多我们可以说切换按钮。也需要我们可以一次只显示一个隐藏的表格。

目前所有代码和表格都可以正常工作，我将这种方法用于手风琴，但不用于表格。

Answer 1

如果我没记错的话，这就是你想要做的： 首先 - 显示加号按钮，并隐藏表格 第二 - 单击加号按钮时显示表格，隐藏加号按钮，并显示减号按钮 第三-当点击减号按钮时，隐藏减号按钮，显示加号按钮，隐藏表格。

您的代码似乎无法正常工作，因为您没有在适当的时间隐藏/显示按钮。我还假设一次应该只显示一个按钮？

$(document).ready(function() {
        $("#t1").hide(); // hide table by default
        $("#close").hide(); //hide the minus button as well if you only want one button to display at a time

  $('#sp1').on('click', function() { //when plus button is clicked
    $("#t1").show(); 
    $("#sp1").hide(); //you need to hide the plus button now
    $("#close").show(); //and then display the minus button
  });
  $('#close').on('click', function() { 
    $("#t1").hide(); //hide table
    $("#close").hide(); //hide minus btn
    $("#sp1").show(); //show plus button
  });
});

Answer 2

你也可以写得短一点

$(document).ready(function() {
  $("#t1, #close").hide();
  $('#sp1, #close').on('click', function() {
    $('#t1, .table-plus-btn, .table-minus-btn').toggle();
  });
});

Answer 3

您可以根据点击隐藏/显示按钮。如果要显示或隐藏行，我添加了函数 toggleButtons(show) ，其中 show 等于。

function toggleButtons(show) {
      if (show) {
        $("#sp1").hide();
        $("#close").show();
      } else {
        $("#sp1").show();
        $("#close").hide();
      }
  }

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