Ajax not calling success function

问题

I'm using ajax to validate a from without reloadind the page.

Script Ajax

    function updateResult(tab){
            $.ajax({
                url:"requeteSpecimen.php",
                data:{datas:tab},
                dataType: 'text',
                async:false,
                success: function(data){
                    document.getElementById('resultat').innerHTML = '<p>'+data+'</p>';
                },
                error: function(data){
                    document.getElementById('resultat').innerHTML = '<p>ERROR</p>';
                }
            });
    }

    $("#filtre").submit(function(){
        <?php $tab=$this->request->data; ?>
        updateResult(<?php json_encode($tab);?>);
    });

</script>

requeteSpecimen.php

<?php echo "Success"; ?>

My problem is that ajax do not call the sucess function, I always have the "ERROR" text appearing ...

For the moment I don't have yet the code of my requeteSpecimen.php file and I just would like the success function to be called. Don't know if it can help but I'm using cakePHP 3.0.

Many thanks in advance.

You do not call actions like that in Cakephp.

First set up an Action in one of your Controllers call the url from your $.ajax function like this.

function updateResult(tab){
        $.ajax({
            url:"/controller/request_specimen",
            data:{datas:tab},
            dataType: 'text',
            async:false,
            success: function(data){
                document.getElementById('resultat').innerHTML = '<p>'+data+'</p>';
            },
            error: function(data){
                document.getElementById('resultat').innerHTML = '<p>ERROR</p>';
            }
        });
}

You could later on add a route for request_specimen and make it prettier.

In your Controller there should be a method called: public function request_specimen() {} Wich will handle the ajax request like so: if($this->request->is(['ajax']) { /* Handle request */}

The data sent to the function will be in $this->request->data;
