database-queries

I'm wanting to create a shoutbox, though I'm wondering if there is another way to go about this rather than using setInterval to query the database for new shouts every number of seconds. Honestly, I don't like having to go about it this way. Seems a bit redundant and repetitive and just plain old wrong. Not to mention the blinking of the shouts as it grabs the data.

So I'm wondering on how the professionals do this? I mean, I've seen shoutboxes that work surperb and doesn't seem to be using any setInterval or setTimeout javascript functions to do this.

Can anyone suggest any ideas or an approach to this that doesn't use setInterval or setTimeout??

Thanks :)

What's the difference between these setInterval calls and which ones should be used? setInterval("myFunction()",1000) setInterval("myFunction",1000) setInterval(myFunction(),1000) setInterval(myFunction,1000) My guess is that JS uses eval() on the first two (strings) and calls the latter two directly… >>> More
