how to refresh an iframe automatically

Question

I would like an iframe to refresh itself to the source path specified. What is the easiest way to do this inline with javascript?

thanks,

Answer 1

setInterval(function(){
    document.getElementById("myframe").src+="";
},2500);

Answer 2

You can use setInterval(function, milliseconds, param1, param2, ...)

Something like this:

var frameRefreshInterval = setInterval(function() {
    document.getElementById("myframe").src = document.getElementById("myframe").src
}, 2000);

The interval resets the iframe's src attribute ever 2 seconds (2000 milliseconds)

Edit, to answer you comments: This, along with any other code that manipulates the DOM, should be in a window.onload event listener or similar like so:

<script type=text/javascript>
window.onload = function() {
    var frameRefreshInterval = setInterval(function() {
        document.getElementById("myframe").src = document.getElementById("myframe").src
    }, 2000);
    // any other code
}
</script>
