private_guy Posted September 7, 2007 Share Posted September 7, 2007 Hi there, I dont know if I should post this in JavaScript or PHP and other codes because I dont know what suits this. I want make a code, which after some many seconds it will disply the code. I posted it in PHP Help and they told me to post it here Example: <html> <? After 3 seconds disply ?> Hello else null <end> You know, something like that . Thanks.

emehrkay Posted September 7, 2007 Share Posted September 7, 2007 setTimeout("alert('try me');", 500); //half a second it ultimately uses eval, so it is a little slow and be careful of it's usage Link to comment https://forums.phpfreaks.com/topic/68411-display-code-after-some-many-seconds/#findComment-343950 Share on other sites More sharing options...
sneamia Posted September 7, 2007 Share Posted September 7, 2007 it ultimately uses eval, so it is a little slow and be careful of it's usage If you need to use a timeout repeatedly (causing lag), what would you suggest instead of setTimeout?

private_guy Posted September 7, 2007 Author Share Posted September 7, 2007 so I put that between <? and why will it use a lot of usage? Link to comment https://forums.phpfreaks.com/topic/68411-display-code-after-some-many-seconds/#findComment-343956 Share on other sites More sharing options...

private_guy Posted September 7, 2007 Author Share Posted September 7, 2007 Thanks but why will it cause high load and usage? Link to comment https://forums.phpfreaks.com/topic/68411-display-code-after-some-many-seconds/#findComment-343984 Share on other sites More sharing options...
emehrkay Posted September 7, 2007 Share Posted September 7, 2007 using setTimeOUt is not going to kill your app. It can be dangerous if you do not protect how script is passed into it var x = "alert('test');"; setTimeout(x,500); if x gets changed, there could be a security problem Link to comment https://forums.phpfreaks.com/topic/68411-display-code-after-some-many-seconds/#findComment-344034 Share on other sites More sharing options...
