Question

我正在处理一个非常讨厌的ajax调用HTMl源，我有使用。我需要获取html响应并将其设置为可以在jQuery自动完成列表中列出。

使用Ajax自动完成功能

  $("#From, #To, #FromVacations, #ToVacations").autocomplete({
      source: function(request, response) {
          $.ajax({
            url: '/list.html',
            data: {
                prefix: request.term,
                type: 'F',
                ver: '1.0'
            },
            dataType: 'html',
            success: function(data) {
                response(data);
            }
          })
      }
  });

所以问题是：如何在自动完成下拉列表中仅显示'li'？ 我还想在下拉列表中保留粗体标记谢谢！

Answer 1

您可以尝试类似

的内容

// ...
success: function(data) {
  var tags = [];
  $('li div',data).each( function() {
    var tag = $(this).html();
    tag = $.trim(tag);
    tag = tag.replace(/\s{2,}/g, ' ');
    tags.push(tag);
  });
  $('#edit').autocomplete( { source: tags } );
}
// ...

根据this answer，您可以尝试使用这样的构造来支持html标记：

// ...
$('#edit').autocomplete({ 
    source: tags,
    select: function(event, ui) {
        var text = ui.item.value;
        text = text.replace(/<\/?[^>]+>/gi, '');
        ui.item.value = text;
    }
}).data("ui-autocomplete")._renderItem = function(ul, item) {
    return $( "<li>" )
        .append( $( "<a>" ).html( item.label ) )
        .appendTo( ul ); 
};

// ...
