Set src inside javascript

Copy linkTweet thisAlerts:
Oct 24.2013

I am trying to change a src from img tag inside javascript code. My html code is the following

[CODE]
<div>
<img id = ‘op’ src = ‘2.png’>
</div>
[/CODE]

and script code

[CODE] var image = 1;
var open = ‘images/’+image+’.png’;
console.log(open);
document.getElementById(“op”).src = open;
[/CODE]

I got the message in the condole Cannot set property ‘src’ of null. Ant idea??

@PadonakOct 24.2013 — maybe you are trying to set the element src attribute before the DOM is loaded?

@rootOct 25.2013 — Try changing this [code=html]<img id = 'op' src = '2.png'>[/code] to [code=html]<img id='op' src='2.png'>[/code] and [CODE]var image = 1;
var open = 'images/'+image+'.png';
console.log(open);
document.getElementById("op").src = open;[/CODE] to something like [CODE]window.onload = function(){
var image = 1;
var open = 'images/'+image+'.png';
//console.log(open); <-- try not using this unless you need to.
document.getElementById("op").src = open;
}[/CODE] and see how you get on.
