CakePHP - How to pass url with ajax? - php

Question

I'm using cakePHP 3.0 and I have a problem while using ajax. Indeed, I would like to execute the action "viewTab" of my controller "SpecimensController" on an array coming from my view "specimen"
<script type="text/javascript" >
var tab = new Array();
function updateResult(){
$.ajax({
type:"POST",
url:"<?php echo Router::url(array('controller'=>'specimens','action'=>'index'));?>",
data:{datas: $("select[name='filtreVariable\\[\\]']").map(function(){return $(this).val();}).get()},
dataType: 'text',
async:false,
success: function(data){
alert('success');
},
error: function (data) {
alert("error");
}
});
}
$("#filtre").submit(function(){
updateResult();
});
</script>
The action "viewTab" is just doing:
echo "success";
But I can't find the right url so the function success can be called. I tried many things and I always have the function error of ajax that is called. :/

If you haven't yet, place this line of code in your AppController where your initialize function is:
public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
}
In your controller for the function you're calling via ajax, try something like this:
public function index()
{
$data = ['testing'];
$this->set(compact('data'));
$this->set('_serialize', 'data');
}
