jqueryui使用ajax自动完成，其源代码是使用foreach从文本文件生成的

我做了很多搜索，得到了很多与我的案例类似的结果，如下所示：

数据源来自文本文件，其格式如下：

postcode,suburb,state,lat,lon
200,AUSTRALIAN NATIONAL UNIVERSITY,ACT,-35.277272,149.117136
221,BARTON,ACT,-35.201372,149.095065
800,DARWIN,NT,-12.801028,130.955789
801,DARWIN,NT,-12.801028,130.955789
804,PARAP,NT,-12.432181,130.84331
810,ALAWA,NT,-12.378451,130.877014
810,BRINKIN,NT,-12.367769,130.869808
810,CASUARINA,NT,-12.376597,130.850489
810,JINGILI,NT,-12.385761,130.873726
810,LEE POINT,NT,-12.360865,130.891349 

我试图作为自动完成字段的源包含的数据是每行的第一个和第二个（邮政编码和郊区）字段。但邮政编码和市郊与州有关。例如ACT是活动状态，所有邮政编码和郊区都是自动完成的来源。我使用

array\u unique（）

删除重复的数据

//take area from state
function take_area(){
    global $wpdb;
    $uploads = wp_upload_dir();
    $upload = $uploads[baseurl];
    $file = $upload.'/csv/suburb_and_area.txt';
    $f = fopen($file, 'r');
    $state = $_POST['state'];
    $counter = 0;
    while($line = fgets($f, 4096)){
        $details = explode(',', $line); 
        $counter++;
        if(trim($details[2]) == $state){
            $state_arr[$counter] = $details[1];
        }
    }
    $option = '';
    if($state!=''){
        $c=0;
        $area_of_state = array_unique($state_arr);
        foreach($area_of_state as $area){
            if($c>0){$option .= ', ';}
            $option .= '"'.$area.'"';
            $c++;
        }
    }
    echo $option;
}

还有JavaScript：

    $("#state").change(function(){
    var state = $('#state :selected').attr('data-value');
    if(!state){
        state = $('#state').val();
    }
    $.ajax({
        url:"<?php bloginfo('wpurl'); ?>/wp-admin/admin-ajax.php", 
        type:'POST',
        data:'action=take_area_from_state&state=' + state,
        success:function(results){
            if(results!=0){
                $("#area").removeAttr("disabled"); 
                $("#area").empty();
                var source = [results];
                $("#area").autocomplete({source: source});
            }else{
                $("#area").attr("disabled", "disabled"); 
            }
        }
    });

});

数据如下所示：

我知道我的代码做错了，但我不知道该怎么做。

我想你需要使用类似

$（函数（）{

---

使用查询参数支持

您是否尝试过

$（“#区域”）.autocomplete（{source:results}）

？您能否显示从服务器获得的响应？您是否使用Firebug？或Chrome的开发工具？您可以在Firebug的控制台或Chrome的net选项卡中查看响应。通过这种方式，您可以查看代码

$（“#区域”）.autocomplete({source:results}）

没有显示任何内容。我无法清除我的浏览器缓存。看起来你没有引用jquery.ui样式表。谢谢你的回答，我在

response（src）

之前尝试过这个方法，并且源代码按字母显示，如

“S

等等。您能按照以下步骤告诉我们结果吗？在ajax回调中

成功：函数（结果）{

添加两条语句

控制台.log（结果）；

和

控制台.log（结果类型）

。然后检查控制台以查看输出。控制台中有两条语句：

“澳大利亚国立大学”“NICHOLLS”、“PALMERSTON”、“AMAROO”、“BONNER”、“FORDE”、“HARRISON”

和

string

。这就是问题所在，响应的类型是

string

而不是

array

。每个项目周围都有双引号吗
