Question

我正在进行自动填充，但是当我在输入中写任何内容时，我会显示所有元素，我想要在输入中包含类型字符的项目。

我的代码是：

var searchRequest = null;
$("#buscar").autocomplete({
    maxLength: 5,
    source: function (request, response) {

        if (searchRequest !== null) {
            searchRequest.abort();
        }
        searchRequest = $.ajax({
            url: 'search.php',
            method: 'post',
            dataType: "json",
            success: function (data) {
                searchRequest = null;
                response($.map(data.items, function (item) {
                        return {
                            value: item.name1,
                            label: item.name1
                        };
                }));
            }
        }).fail(function () {
            searchRequest = null;
        });
    }
});

试试这个：

  source: function(request, response) {
        response($.map(data.items, function(item) {
            var term = request.term.toLowerCase(),
                name = item.name.toLowerCase();
            if (name.search(term) == 0 || item.code.indexOf(term.toUpperCase()) == 0) {
                return {
                    label: item.name,
                    value: item.name
                };
            }
        }).slice(0, 15)
       );
  },
