跨原点读阻塞

在我的网站上我有一个搜索框。我已尝试关闭自动填充建议,并创建一个由数据库中的建议填充的Div。

我的HTML是这样的:

<input type="text" id="searchbox" onkeyup="searchq();" autocomplete="off">
<input type="image" src="media/icons/search.png" id="search_button">
<div id="search_suggestions"></div>

然后我有一个类似这样的JS函数,它接受输入的内容并用一个单独的php文件查询db:

function searchq(){
    var search_text = $("#searchbox").val();
    console.log(search_text);
    $.post("get_search_suggestions.php", {search_text: search_text}, function(output){
        $("#search_suggestions").html(output);
    });
}

$product_search_result = "";
if(isset($_POST['search_text'])){
    $term = $_POST['search_text'];
    $new_term = '%'.$term.'%';

    $params = [$new_term];
    $sql = "SELECT * FROM products WHERE name LIKE ?";
    $stmt = DB::run($sql,$params);
    $resultCount = $stmt->rowCount();
    if($resultCount > 0){
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
            $id = $row["pro_id"];
            $product = $row["".$lang.""];

            $params1 = [$id];
            $sql1 = "SELECT * FROM products WHERE id=?";
            $stmt1 = DB::run($sql1,$params1);
            while ($row = $stmt1->fetch(PDO::FETCH_ASSOC)){
                $url = $row["url"];
                $product_name = $row["product_name"];
            }
            $product_search_result .= "<a href='product/$url'>";
            $product_search_result .= translate($product_name);
            $product_search_result .= "</a>";
        }
    }
}
echo $product_search_result;

这对我在Windows和Android上运行很好,但是一个使用mac的用户在控制台中看到以下内容:

任何关于如何解决这一问题的建议或想法都将不胜感激。我不知道为什么这些文件会被视为跨源文件,尽管这些文件位于主目录的同一目录或子目录中。
