php - Javascript location doesn't work -

i tried redirect page through button not perform function.

please tel me problem in code?

you need wrap location you’re sending user in quotes because otherwise javascript try interpret variable name:

echo"<button class='buttonajax' onclick='javascript:location = \'try.php;\''>go back</button>";
