How To Change Content Of Div Using Javascript?

Hi I am building an HTML site & to place ads inside that I need a javascript code to change it or update it from on script page not by going every page & cut/paste that ad

Solution 1:

document.getElementById('adcode').innerHTML = 'HTML code provided by ad networks';

innerHTML is not a function, it is a variable. ALso, you had a . after getElementById.

A better way, however, would be something like this:

var text = document.createTextNode('HTML code provided by ad networks');
document.getElementById('adcode').appendChild(text);

If you use this method, the text will be automatically escaped for you.
