如果我们在名称文本框中按任意数字，将显示一个列表。但是这个自动列表应该只在搜索按钮打开时显示，否则我们必须手动输入。我如何在 JQuery 中执行此操作？

最佳答案

我认为您应该在检查开关时忽略数据列表，方法是断开它们之间的唯一链接，即 id，如下所示:

$(document).ready(function(){
  $('#myonoffswitch').change(function(){
    if($(this).is(':checked'))
      $('#mylist').next('datalist').attr('id','product_name');
    else
      $('#mylist').next('datalist').attr('id','product_name1');
  });
});

同时将搜索字段的id作为mylist进行选择

<input list="product_name" name="item_name" id="mylist">

完整的工作片段:

$(document).ready(function(){
  $('#myonoffswitch').change(function(){
    if($(this).is(':checked'))
      $('#mylist').next('datalist').attr('id','product_name');
    else
      $('#mylist').next('datalist').attr('id','product_name1');
  });
});
