Question

我的PHP：

    <?php
require_once __DIR__ . '/../inc/_puredb.php';
$query = $db->prepare("SELECT user_name FROM users");
$query->execute();
if($query->rowCount() > 0) {
    $rows = array();
    while($res = $query->fetchObject()) {
        array_push($rows, array($res->user_name => '/img/users/' . $res->user_name . '/avatar.png'));
    }
    echo json_encode($rows);
} else
    echo "";
?>

我的JS：

$.ajax({
    url: "/ajax/PermissionAutocomplete.php",
}).done(function(resJson) {
    if(resJson !== "") {
        //var resJson = JSON.parse(resJson); <- this is commented to try if it worked better without it
        $('input.mauto').autocomplete({
            data: resJson,
            limit: 10,
        });
    }
});

任何想法为何不起作用？我正在使用Materialise：http://materializecss.com/forms.html#autocomplete

PHP输出：

[{"User1":"\/img\/users\/User1\/avatar.png"},{"User2":"\/img\/users\/User2\/avatar.png"}]

您需要将 resJson变量从对象数组转换为对象。从：

[{"User1":"\/img\/users\/User1\/avatar.png"},{"User2":"\/img\/users\/User2\/avatar.png"}]

为：

{"User1":"/img/users/User1/avatar.png","User2":"/img/users/User2/avatar.png"}

为了实现这一目标，您可以使用arr.reduce(callback, [initialValue])：

摘录：

$(function () {
  var resJson = [{"User1":"\/img\/users\/User1\/avatar.png"},{"User2":"\/img\/users\/User2\/avatar.png"}];
  $('input.autocomplete').autocomplete({
      data: resJson.reduce(function(obj, item){
          var key = Object.keys(item)[0];
          obj[key] = item[key];
          return obj;
      },{}),
      limit: 20, // The max amount of results that can be shown at once. Default: Infinity.
  });

});

        </div>

</div>

从PHP实现MaterialiseJS自动完成？
