setInterval not working (firing only once) in Google Chrome extension
setInterval(function() { alert('only shown once') },2000);You need to pass a function reference like alert and not a return value alert()
setInterval isn't working at all.
The first argument should be a function, you are passing it the return value of alert() which isn't a function.
Use the three argument version:
setInterval(function,time,array_of_arguments_to_call_function_with);setInterval(alert,2000,['only shown once']);
The way you wrote it it's wrong:
setInterval() wants a function and a numerical value: setInterval(function(){//your code}, timeInterval).
