Php 自动完成dos不显示传递自定义值的结果

我正在尝试将自定义值传递给autocomplete，因此：

我的自定义工作值基于

使用默认源（如文档）：

    $("#inpPesqCli").autocomplete({
        source: "ajax/search.php",
        minLength: 2,
        autoFocus: true
    });

firebug返回以下示例：

[...
  { "id": "29083", "label": "SOME ONE 2", "value": "SOMEONE WITH LELE" },

  { "id": "19905", "label": "SOME ONE", "value": "SOMEONE WITH LALA"},
...]

工作很完美，结果就出来了

当我尝试设置一些自定义值时：

$("#inpPesqCli").autocomplete({
    source: function( request, response ) {
        $.ajax({
            url: "ajax/search.php",
            dataType: "jsonp",
            data: {
                featureClass: "P",
                style: "full",
                maxRows: 12,
                name_startsWith: request.term
            },
            success: function( data ) {
                response( $.map( data.geonames, function( item ) {
                    return {
                        label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
                        value: item.name
                    }
                }));
            }
        });
    },
    minLength: 2,
    autoFocus: true
});

firebug返回给我的是完全相同的数组结果：

  [...
  { "id": "29083", "label": "SOME ONE 2", "value": "SOMEONE WITH LELE" },

  { "id": "19905", "label": "SOME ONE", "value": "SOMEONE WITH LALA"},
  ...]

但是，问题是，当我通过自定义计算时，结果的dosent显示出来

不知道我遗漏了什么。

设置ajax type=GET，也许可以工作，默认情况下数据发送类型是POST

    $("#inpPesqCli").autocomplete({
    source: function( request, response ) {
        $.ajax({
            url: "ajax/search.php",
            dataType: "jsonp",
            type : "GET",
            data: {
                featureClass: "P",
                style: "full",
                maxRows: 12,
                name_startsWith: request.term
            },
            success: function( data ) {
                response( $.map( data.geonames, function( item ) {
                    return {
                        label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
                        value: item.name
                    }
                }));
            }
        });
    },
    minLength: 2,
    autoFocus: true
});

    $("#inpPesqCli").autocomplete({
    source: function( request, response ) {
        $.ajax({
            url: "ajax/search.php",
            dataType: "jsonp",
            type : "GET",
            data: {
                featureClass: "P",
                style: "full",
                maxRows: 12,
                name_startsWith: request.term
            },
            success: function( data ) {
                response( $.map( data.geonames, function( item ) {
                    return {
                        label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
                        value: item.name
                    }
                }));
            }
        });
    },
    minLength: 2,
    autoFocus: true
});
