alert notation

[niche]

How should the alert be written if all I wanted displayed was the <div> and its style based on this function? alert(document.body.div); displayed as undefined.

var div = document.createElement('div');div.setAttribute("style","float:right;width:200px;height:100px;background-color:red");div.id='mydiv2';var txt='hello world!';document.getElementsByTagName('body')[0].appendChild(div);document.getElementById('mydiv2').innerHTML=txt;alert(document.body.innerHTML);}

If you want to display the style:alert(div.getAttribute('style'));

How would I target the div with the id=mydiv2 in the alert?

[justsomeguy]

Use document.getElementById.

Edit: Didnt see that post above!Hmm... Could you usealert(div#mydiv2.getAttribute('style'));or maybe create it as a variable likealert(myvar.getAttribute('style'));Dont take my word for it because I am quite new to Javascript ;P

Thanks for your post danman97, but neither of those alerts worked.I think I'm get the hang of this. This alert worked: alert(document.getElementById('mydiv2').getAttribute('style'));Is there a shorter notation that could be used?

That is the shortest!

Your Welcome... Even though my method didn't work.

The second one would have worked if you first assigned the DOM element to myvar before using it in the alert:

var myvar = document.getElementById('mydiv2');alert(myvar.getAttribute('style'));

I love your follow-ups shadowMage. We always benefit from a double check of a topic.
