我不知道如果我累了，或者爲什麼我不能得到它的權利，請幫助我需要的JSON獲取表單值使用AJAX

Question

是

<script language="javascript"> 
$(document).ready(function(){ 
    getResultsCountry(); 
}) 

function getResultsCountry() { 
    $.ajax({ 
     url:'suggest_country.html', 
     type:'POST', 
     data: 'q=', 
     dataType: 'json', 
     success: function(json) { 
     $('#country')[0].options.length = 0; 
     $.each(json, function(i, value) { 
      if (value=='<?php echo $country; ?>') { 
       $('#country').append($('<option>').text(value).attr('value', value).attr('selected', 'selected')); 
      } else { 
       $('#country').append($('<option>').text(value).attr('value', value)); 
      }; 
     }); 
     } 
    }); 
}; 
</script> 

代碼在外部文件看起來像

<?php 


    $results = mysql_query('SELECT DISTINCT country FROM MyTable WHERE country LIKE \'%\' ORDER BY country'); 

    while($result = mysql_fetch_array($results)) { 
     $cities = $cities.' short = \''.$result['country'].'\' OR';  
    } 

    $cities = substr($cities, 1,strlen($cities)-3); 

    $results2 = mysql_query('SELECT full, short FROM `Countries` WHERE '.$cities); 
    $json = array(); 
    while($result2 = mysql_fetch_array($results2)) { 
     $json[] = $result2['short'].','.$result2['full']; 
    } 

    echo json_encode($json); 
    mysql_close($db2); 
?> 

響應我越來越是

["AG,ANTIGUA AND BARBUDA","AU,AUSTRALIA","BR,BRAZIL","CA,CANADA","KY,CAYMAN ISLANDS","CN,CHINA"] 

我需要的是填寫它的選項標籤我也得到這部分，但我不能讓它填充c國家代碼AG作爲價值和名稱像名稱一樣

<option value="AG">Antigua</option> 

請爲我打破它我真的很困惑和厭倦了它的小時頭痛。

Answer 1

您需要拆分值

$.each(json, function(i, value) { 
      var arr_values = value.split(','); 
      if (value=='<?php echo $country; ?>') { 
       $('#country').append($('<option>').text(arr_values[1]).attr('value', arr_values[0]).attr('selected', 'selected')); 
      } else { 
       $('#country').append($('<option>').text(arr_values[1]).attr('value', arr_values[0]))); 
      }; 
     }); 

Answer 2

這將使如果你沒有拆你的字符串你的Ajax回調更容易..

while($result2 = mysql_fetch_array($results2)) { 
    $json[] = array('short'=>$result2['short'], 
        'full' => $result2['full'] 
      ); 

}

然後你可以解析

$.each(json, function(i, value) { 
      if (value['full']=='<?php echo $country; ?>') { 
       $('#country').append($('<option>').text(value['full']).attr('value', value['short']).attr('selected', 'selected')); 
      } else { 
       $('#country').append($('<option>').text(value['short']).attr('value', value['full']))); 
      }; 
     });
