Multiple Webcams

June 9, 2004 12:43 PM

I'm trying to get a bunch of webcams running on the same page. I found a Javascript refresh script, and tried to adapt it to work for more than one cam. Of course, if I had any knowledge of Javascript, I might have succeded, but I don't, so take a look inside and lend me a hand, if you please.

Here's what I have:




var refreshrate1=5; //SECONDS BETWEEN REFRESH
var image1="http://82.35.18.32:8080/gobcam.jpg"; //IMAGE NAME
var imgheight1=240; //IMAGE HEIGHT
var imgwidth1=320; //IMAGE WIDTH

function refresh(){
document.images["pic1"].src=image1+"?"+new Date();
setTimeout('refresh()', refreshrate1*1000);
}

document.write('');

if(document.images.pic1)window.onload=refresh;


var refreshrate2=5; //SECONDS BETWEEN REFRESH
var image2="http://82.35.21.220:8080/smurgcurmpurp.jpg"; //IMAGE NAME
var imgheight2=240; //IMAGE HEIGHT
var imgwidth2=320; //IMAGE WIDTH

function refresh(){
document.images["pic2"].src=image2+"?"+new Date();
setTimeout('refresh()', refreshrate2*1000);
}

document.write('');

if(document.images.pic2)window.onload=refresh;




The second cam works fine, but the first cam doesn't work at all. Any suggestions?

You have two functions named refresh(), which are interfering with each other. Try controlling both images from within the same function:

function refresh(){
document.images["pic1"].src=image1+"?"+new Date();
document.images["pic2"].src=image2+"?"+new Date();
setTimeout('refresh()', refreshrate1*1000);
}

Response by poster: Aaah, I see. I thought refresh was a non-user defined command. I'll give your suggestion a go.
