Question

我需要基于用户从下拉菜单中选择选项和单选按钮来显示div的不同组合。一旦从下拉列表中选择了一个值，单选按钮将出现，然后根据单选选项值出现这些框。

例如：

“选项1”和“是”将显示内容框1和4
“选项1”和“否”将显示内容框2和3
“选项2”和“否”将显示内容框和4

我们正在使用jquery，并且能够显示单选选项，但是我不知道如何基于两个值显示框。

(function() {

  function runOffer() {

    // Show/hide radio buttons
    $('#selectOption').change(function() {
      $('.radio-btnWrapper').show();
    });

  }

  var checkJQ = window.setInterval(function() {
    if (typeof $ !== 'undefined') {
      window.clearInterval(checkJQ);
      runOffer();
    }
  }, 50);
})();

编写一个函数，该函数根据下拉列表和单选按钮的值显示适当的内容框。然后从它们的更改处理程序中调用它。

(function() {

  function showContents() {
    let select = $("#selectOption").val();
    let radio = $(".Radio-input:checked").val();
    $(".Box").hide(); // hide all the boxes first, then show based on the selections
    if (select == "a" && radio == 'Yes') {
      $(".contentBox1, .contentBox4").show();
    } else if (select == "a" && radio == 'No') {
      $(".contentBox2, .contentBox3").show();
    } else if (select == 'b' && radio == 'Yes') {
      $(".contentBox4").show();
    }
  }

  $('#selectOption').change(function() {
    $('.radio-btnWrapper').show();
    showContents();
  });

  $(".Radio-input").change(function() {
    showContents();
  });
})();
