Question

我正在创建一个jQuery过滤器搜索。

我希望能够在过滤的类别中进行搜索。我可以过滤出类别，但是如果我在所选类别中搜索，则搜索将搜索整个对象，而不仅限于所选类别。

搜索几乎可以正常进行，但是我不确定如何在类别标准内实现搜索。

非常感谢任何帮助或建议

$(document).ready(function(){
  $("#searchInput").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#searchFilterDiv div.CompanyDirectoryItem").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
    if($('#searchFilterDiv div.CompanyDirectoryItem:visible').length===0){
          $('.error').show();
        }else{
          $('.error').hide();
        }
  });
});


  $(".filter-button").on("click", function(){
   
         var selectItem = $(this).data('category');
         filter(selectItem);
    });


  function filter(e) {
      var regex = new RegExp('\\b\\w*' + e + '\\w*\\b');
      		$('.CompanyDirectoryItem').hide().filter(function () {
          return regex.test($(this).data('name'))

您只想从可见部分搜索：

$("#searchFilterDiv div.CompanyDirectoryItem:visible").filter(function() {

编辑

为了保持搜索/过滤功能，我建议使用分离/附加：

let tmp=[];
function filter(e) {
  if(tmp.length>0)
    tmp.map(x => x.appendTo($('#searchFilterDiv')));

    var regex = new RegExp('\\b\\w*' + e + '\\w*\\b');         
    $('.CompanyDirectoryItem').detach().filter(function () {
      if(regex.test($(this).data('name')))
        return true
      else
        tmp.push($(this))
    }).appendTo($('#searchFilterDiv'));
}

现在您可以使用初始搜索/过滤功能

$("#searchFilterDiv div.CompanyDirectoryItem").filter(function() {

jQuery过滤器搜索需要在类别内搜索
