Question

我有这个JS：

<script>
jQuery(document).ready(function(){ // we wait until DOM is ready
    jQuery('#veranstort').change(function(){ // fire when input is filled

        origin = "55767 Schwollen";
        destination = "13509 Berlin";

        jQuery.ajax({ // we build the AJAX request
                method:"POST", 
                url:"index.php?option=com_rsform&formId=6&action=ajax", 
                data: {origin, destination},
                success: function(results) {
                    console.log("results: " + results);

                }
        });
    });
})
</script>

触发此php脚本：

$action = JRequest::getWord('action'); // we will need a parameter to run the script
if ($action == "ajax") { // if condition is met, run the script

    $origin = $_POST['origin']; // get the origin
    $destination = $_POST['destination']; // get the destination
    var_dump("destination: ".$destination); // this gives me NULL!!

    $distance = file_get_contents("https://maps.googleapis.com/maps/api/distancematrix/json?origins=".$origin."&destinations=".$destination."&key=GMAPSKEY"); // build the URL according to the API

    $distance = json_decode($distance); // decode the response from JSON

    print_r($distance->rows[0]->elements[0]->distance->text);die(); // print the result so we can catch it in the AJAX call

}

这已经有一段时间了，但是现在没有了。我无法在php中访问目标或起点值。我在做什么错了？

Answer 1

错误是由于网址中缺少/而引起的。它被重定向，并且POST数据在此过程中丢失了。

正确的网址：

url:"/index.php?option=com_rsform&formId=6&action=ajax"

Answer 2

脚本文件就可以了。请更改ajax文件的条件。

$action = $_GET['action'];

if ($action == "ajax") { // if condition is met, run the script


     //// Here process your code
}

具有结果处理程序的简单Ajax调用不起作用
