JQuery 如何 .find() 不区分大小写？

Question

<Manufacturers>
  <Manufacturer name="abc">
    <flags=""/>
  </Manufacturer><Manufacturer name="abcd">
    <flags=""/>
  </Manufacturer>
  <Manufacturer name="abcde">
    <flags=""/>
  </Manufacturer>
<Manufacturers>

我想只打印名称中包含字符串“bc”的制造商的名称

这是我迄今为止的尝试

      $( "#autocomplete" ).on( "filterablebeforefilter", function ( e, data ) {
        var $ul = $(this);
        html = "";
        $ul.html( "<li><div class='ui-loader'><span class='ui-icon ui-icon-loading'></span></div></li>" );
        $ul.listview( "refresh" );
        $.ajax({
                type: "GET",
                url: "./Sources.xml",
                datatype: "xml",
                error: function(jqXHR, textStatus, errorThrown) {
                    console.log('Error: ' + errorThrown);
                },
                success: function(xml.toLowerCase()) {
                    console.log('AJAX Request is succeded.');

                    $(xml).find('Manufacturer[name*="' + $(data.input).val() + '"]').each(function(){
                        console.log($(this).attr('name'));
                    });
                    $ul.html(html);
                    $ul.listview( "refresh" );
                    $ul.trigger( "updatelayout");
                }
            });

    });

问题是 .find() 区分大小写。我怎样才能做同样的事情但不区分大小写

您应该匹配“Manufacturer”，然后按制造商名称进行搜索，并且查询在函数中都转换为小写，而不是在查找中构建检查

$(xml).find("Manufacturer").each(function(i){
  console.log($(this)[0].attributes.name.value.toLowerCase().indexOf(query.toLowerCase()) >= 0;
})
