[RESOLVED] setTimeout with variable value

Copy linkTweet thisAlerts:
Mar 05.2012

Hi all,

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

This is what I am working with:

[code]
function Refresh() {

var rStr = “<?php echo $ScreenRefreshRate ?>”;

setTimeout(“Refresh()”, rStr );
[/code]

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

Many thanks in advance.

@RodionGorkMar 05.2012 — Just remove quotes around php tag and make it inline:

[CODE]
var rStr = <?=$ScreenRefreshRate?>;
[/CODE]

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

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

setTimeout("Refresh()", rStr );
}[/CODE]

you were missing closing brace

@hyperionXSMar 05.2012 — If you want this function to be calles every X miliseconds, use window.setInterval
[CODE]
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.
[/CODE]

@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.
