How to redirect with jquery ajax and php response

I have the following ajax and php. I want to redirect the user to a another page depending on the result i output with a php script. Php successfully returns the json to browser, but i am somehow not able to get the response url back into the js ajax to make the redirection. It always redirects me to /undefined. What is wrong with my code?

jQuery.ajax({
    type: "POST",
    url: "../custom_scripts/anmeldung_zurueckziehen.php",
    data: { anmeldung_id: anmeldung_id },
    success: function(response){    
    //alert (response.redirect);
    if (response.redirect) {
        window.location.href = response.redirect;
    }else {
        // Process the expected results...
    }
    }
})

This is the php. 

$arr = array ('redirect'=>true,'redirect_url'=>'https://mypage.de/no- 
access/');
echo json_encode($arr);

Two ways to do this

First way is - Either use JSON headers in Php like below 

header('Content-Type: application/json');

Above will return JSON string with json headers and jquery will automatically parse it for you and your callback function will have proper object.

Second Way is - in javascript use JSON.parse like below 

 JSON.parse(response);

Above will basically parse your json string into Javascript object

Make sure you don't parse when you have set JSON headers from backend.

You are missing dataType property for ajax to decode the response:

jQuery.ajax({
    type: "POST",
    dataType: "json",
    url: "../custom_scripts/anmeldung_zurueckziehen.php",
    data: { anmeldung_id: anmeldung_id },
    success: function(response) {    
        //console.log(response.redirect);
        if (response.redirect) {
            window.location.href = response.redirect_url;
        } else {
        // Process the expected results...
        }
    }
})

Wish this helps:

jQuery.ajax({
    type: "POST",
    url: "../custom_scripts/anmeldung_zurueckziehen.php",
    data: { anmeldung_id: anmeldung_id },
    success: function(response){    
    response = JSON.parse(response);
    if (response.redirect) {
        window.location.href = response.redirect_url;
    }else {
        // Process the expected results...
    }
    }
})
