if statement not working jquery - php

Question

This should be simple, but doesn't work
Essentially I want to get a return result and reload my page if the answer is 'yes'
Here is the
timer.php
<?php
$filename = 'timer.tmr';
if (file_exists($filename)) {
unlink($filename);
echo 'yes';
} else {
echo 'no';
}
?>
and here is the script in my main file
var myVar = setInterval(function () {myTimer()}, 5000);
function myTimer() {
sendto = "timer.php";
$.get(sendto, function(data, status) {
if (data === 'yes') {
location.reload();
}
});
}
Basically in the timer.php
If the file exists I delete it and return a 'yes'
But the jquery doesn't do the reload function, if I check the data with an alert(data), it returns a 'yes' So I just don't understand the problem.

Answer 1

If you are getting into the if condition, then you should try window.location.href = window.location.href; instead of location.reload();
and If you're not getting into the if condition, change condition with if ($.trim(data) === "yes")
thanks to Shaunak Shukla (again thank you)
here is the final solution
var myVar = setInterval(function () {myTimer()}, 10000);
function myTimer() {
sendto = "timer.php";
$.get(sendto, function(data, status) {
if ($.trim(data) === "yes"){
location.reload();
}
});
}
it needed the trim(data) must have had something in it..

Answer 2

Use json_encode in the echos and improve your checking:
<?php
$filename = 'timer.tmr';
if (file_exists($filename)) {
unlink($filename);
if (!file_exists($filename))
echo json_encode('yes');
else
echo json_encode('no');
} else {
echo json_encode('no');
}
?>
And change the reload to a more direct scope:
var myVar = setInterval(function () {myTimer()}, 5000);
function myTimer() {
sendto = "timer.php";
$.get(sendto, function(data, status) {
if (data === 'yes'){
window.location.reload();
}
});
}

Answer 3

Let complete ajax request then try to reload :
setTimeout(function(){// wait for 5 secs(2)
location.reload(); // then reload the page.(3)
}, 5000);

Answer 4

I would Suggest, please check the Type casting (data type). I find, you have used === , it will check string to string or int to int.
