How to change content of div using Javascript?

Question

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 code. I entered this in script page document.getElementById.('adcode').innerHTML('HTML code provided by ad networks'); And in my website I used this code <div id="adcode"> </div> But it is not showing anything even if I entered any other HTML code.

Answer 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.

• Florian Margaine: Would you mind explaining why innerHTML is bad? It may not be in the DOM standard, but it clearly is a de-facto standard.
• tckmn: @FlorianMargaine It's still better to conform to standards, and furthermore createTextNode does escaping for you.
• Benjamin Gruenbaum: Non standard?
• Mayuresh: still not working 4 me. Listen again I want to ad it from one location and to inside all of my webpages.
• tckmn: @Mayuresh Umm... I don't understand what you're saying. Doesn't this add the text that you want?
