 function disabled_all(){

  $('input[name="fruits"],input[name="animals"],input[name="fruits"], select[name="persons"],select[name="animals"],select[name="fruits"]').prop('disabled', true);

  }

 

 disabled_all();

 

 $('.browser-default').on('change', function () {

    var type = $(this).val();

    disabled_all();

    $('input[name="' + type + '"], select[name="' + type + '"]').prop('disabled', false);

}).trigger('chnage');

Answer 2

您可以遍历所有具有相同名称并启用该单选按钮的单选按钮。此外，启用选择框使用 $("select[name='" + $(this).val() + "']").prop("disabled", false); 。

演示代码：

$(document).ready(function() {

  $("#type").change(function() {

  //disable other select

   $('select:not(#type)').prop("disabled", true);

    $("input").prop("checked", false);

    $("input").prop('disabled', false);

    $("input[type='radio']").prop("disabled", true);

    //looping through all inputs

  $("input[name='" + $(this).val() + "']").each(function(){

   $(this).prop("disabled", false); //remove disable

  })

  //remove disabled from slect

 $("select[name='" + $(this).val() + "']").prop("disabled", false);

 

  }).trigger("change");

})
