html - Autoscroll in bash script output called from PHP -
i have php script prints output of bash script (actually expect script), looks this:
<?php ob_implicit_flush(true); ob_end_flush(); $cmd = "./expect_script.sh"; $descriptorspec = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("pipe", "w") ); $process = proc_open($cmd, $descriptorspec, $pipes, realpath('./'), array()); echo '<pre>'; if (is_resource($process)) { while ($s = fgets($pipes[1])) { print $s; } } echo '</pre>'; ?> so wanted real time output automatic scroll @ end of page every new line appearance , found this: printing process output in realtime
then added proposed html code script follows:
<html><head> <script language="javascript"> var int = self.setinterval("window.scrollby(0,1000);", 200); </script> </head> <body> <?php ob_implicit_flush(true); ob_end_flush(); $cmd = "./expect_script.sh"; $descriptorspec = array( 0 => array("pipe", "r"), 1 => array("pipe", "w"), 2 => array("pipe", "w") ); $process = proc_open($cmd, $descriptorspec, $pipes, realpath('./'), array()); echo '<pre>'; if (is_resource($process)) { while ($s = fgets($pipes[1])) { print $s; } } echo '</pre>'; ?> </body> </html> however, when script finishes web browser won't let me browse top of page because still scrolling bottom.
how shall avoid can browse once script finished?
you using setinterval repeat task , never ask stop that.
you need stop setinterval repeating , @ end of php code add :
echo '</pre>'; echo '<script language="javascript">self.clearinterval(int);</script>'; also need close proc process :
if (is_resource($process)) { while ($s = fgets($pipes[1])) { print $s; } proc_close($process); }
