javascript - ajax 调用中不同浏览器的不同错误

Question

这个错误的原因是什么？我该如何解决？谷歌浏览器错误:

An error has occured: [object Object] parsererror SyntaxError: Unexpected token ILLEGAL

歌剧错误:

An error has occured: [object Object] parsererror SyntaxError: JSON.parse: Unable to parse value:

ie9 错误:

An error has occured: [object Object] parsererror SyntaxError: Invalid character

和...

js代码:

$('#hotel').keypress(function () {
    var dataObj = $(this).closest('form').serializeArray();
    $.ajax({
        url: 'http://localhost/mehdi/admin/tour/search_hotel',
        data: dataObj,
        dataType: 'json',
        success: function (data) {
            $("#suggestion_tab").html('');
            $.each(data.suggestions, function (a, b) {
                $("#suggestion_tab").append('<li>' + data.b + '</li>');
            });
            // Display the results
            ///alert(data);
        },
        "error": function (x, y, z) {
            // callback to run if an error occurs
            alert("An error has occured:\n" + x + "\n" + y + "\n" + z);
        }
        });
    });

php:(CI_Controller)

function search_hotel(){
    $searchterm = $this->input->post('search_hotel');
    $result = $this->model_tour->search_hotel($searchterm);
    while($row = mysql_fetch_assoc($result))
    {
        $output[] = $row;
    }
    echo json_encode(array('suggestions' => $output));
}

CI_模型

function search_hotel($searchterm)
{
    return mysql_query("select * from hotel_submits where name LIKE '".$searchterm."'");
}

您的 JSON 包含无效语法。
您需要查看实际的 JSON 并修复错误。
