[RESOLVED] setTimeout with variable value

[dcjones]

Hi all,

I need to pass the content of a PHP variable to a JavaScript setTimeout function.

This is what I am working with:

function Refresh() {

var rStr = "<?php echo $ScreenRefreshRate ?>";

setTimeout("Refresh()", rStr );

I don't think I am coding this correctly, can anyone advise please.

Many thanks in advance.

Just remove quotes around php tag and make it inline:

var rStr = <?=$ScreenRefreshRate?>;

Hope I write correctly though in haste and having very little skills in PHP. Sorry if something wrong %)

function Refresh() {

var rStr = "<?php echo $ScreenRefreshRate ?>";

setTimeout("Refresh()", rStr );
}

you were missing closing brace

If you want this function to be calles every X miliseconds, use window.setInterval

function Refresh() {
  // function body
}
window.setInterval("Refresh()", <?php echo (int) $ScreenRefreshRate ?>) 
// I put (int) just to make sure it's not giving JS error if you send anything else than an INT.

@RodionGork: Try to avoid using <?=$var ?> and get used to use allways <?php echo $var ?>. There are some webservers out there that don't interpret the short form of PHP.
