Ajax 函数没有得到 cakephp caontroller 函数的任何响应

Question

我有一个 jquery 函数如下：

$(document).ready(function() {
    get_search_results();
});

function get_search_results() {
    //get the selected location_id

    var gal_location_id = 0;


    //get the selected package
    var starting_package_wedding = 1;

    var data = "gal_location_id="+gal_location_id+"&starting_package_wedding="+starting_package_wedding;

    var url_to_call = "http://localhost/myshaadi/gal_providers/api_search"; //No alerts
    //var url_to_call = "http://localhost/myshaadi/photographers/gen_uid"; //Alerts 

    $.ajax({
        type: "GET",
        url: url_to_call,
        // async: false,
        //dataType: "json",
        data: data,
        error:function(resp){

        },
        success: function(resp){
            alert(resp);
            //render_search_result(resp);
        }
    });
}

控制器gal_providers函数api_search()是：

function api_search() {
return 'Hello';
}

但是页面并没有提醒任何东西。此外，如果我将变量 url_to_call 更改为其他控制器功能，它会发出警报！所以我想知道错误是什么？

编辑： search.ctp

<style>
#search_filters{
    border: 1px solid silver;
    line-height: 22px;
}
#search_filters .header{
    background-color: orange;
    padding: 5px;
    margin-bottom: 10px;
}
</style>
<script>

$(document).ready(function() {
    get_search_results();
});

function get_search_results() {
    //get the selected location_id

    var gal_location_id = 0;


    //get the selected package
    var starting_package_wedding = 1;

    var data = "gal_location_id="+gal_location_id+"&starting_package_wedding="+starting_package_wedding;

   var url_to_call = "http://localhost/myshaadi/gal_providers/api_search"; //No alerts
    //var url_to_call = "http://localhost/myshaadi/photographers/gen_uid"; //Alerts 
    $.ajax({
        type: "GET",
        url: url_to_call,
        // async: false,
        //dataType: "json",
        data: data,
        error:function(resp){

        },
        success: function(resp){
            alert(resp);
            //render_search_result(resp);
        }
    });
}

Answer 1

在你的函数 api_search() 中使用 echo 而不是 return 并尝试。

api_search() {
echo 'Hello';
}

Answer 2

function api_search() {
echo "Hello";
exit;
}
