I want to set timer on body onload eventHandler to call function where I show hide div.
div for easier selection through javascript.onload attribute, I'm calling setInterval, which gets an anonymous function as a first parameter.theDiv, and set its css display attribute to block, or none (depending on the previous value).JSFiddle for demonstration: http://jsfiddle.net/GAE8L/1/
Note that the first parameter for setInterval is just the function name, not a function call (so no parenthesis!):
