Question

我是一名新手，尝试使用JQuery自动完成插件。但我无法在console.log和alert中获得结果，但无法通过自动完成建议获得结果。但不在建议列表中。

输入字段

'Name: <input type="text" id="hint" name="hint" />'

jquery

$(document).ready(function () {
    $("#hint").keyup(function () {
            $( "#hint" ).autocomplete({
        source: function(request, response) {
            //console.info(request, 'request');
            //console.info(response, 'response');

            $.ajax({
                //q: request.term,
                url: "<?php echo base_url(); ?>index.php?Librarian/autocomplete/",
                data: { term: $("#hint").val()},
                dataType: "json",
                type: "POST",
                success: function(data) {
                    alert(data)
                    console.log(data);
                    response(data);
                }
            });
        },
        minLength: 2
    });
  }); 
});

控制器

function autocomplete($param1 = '', $param2 = '', $param3 = '') {
    // load model
    $this->load->model("Librarian_model");
    $search_data = $this->input->post('term');


    $result = $this->Librarian_model->get_autocomplete($search_data);

    echo json_encode($result); 
    //returning the result as result_array() also tried implode function but got the error at response

}

输出在控制台日志中： enter image description here

在警报中，我得到了object-object，但是当我使用JSON.stringify时，输出是一个数组

表明您是ajax响应格式问题的接缝，使用map函数格式化ajax响应-

$(document).ready(function () {
    $("#hint").keyup(function () {
            $( "#hint" ).autocomplete({
        source: function(request, response) {
            //console.info(request, 'request');
            //console.info(response, 'response');

            $.ajax({
                //q: request.term,
                url: "<?php echo base_url(); ?>index.php?Librarian/autocomplete/",
                data: { term: $("#hint").val()},
                dataType: "json",
                type: "POST",
                success: function(data) {
                    alert(data)
                    console.log(data);


                    response($.map(data, function (item) {
                        return {
                            label: item.name,
                            value: item.name
                        };
                    }));


                }
            });
        },
        minLength: 2
    });
  }); 
});

jQuery UI自动完成插件不起作用
