Document access

JavaScript
1

Hi
I’m new to javascript and I’m currently working through the Sitepoint Simply Javascript
book. I’m a little bit stuck on chapter 3, Document Access.
I’ve tried out the example on accessing the node you want, like:
getElementById, etc.

I’ve copied over the example “target” out of the book to see how it works yesterday
and it worked great. Now today I tried the same example by using an “if” statement.
Now when I run the program it doesn’t seem to find the “id”. It displays the alert box
“Not found”.
Please help!
Here’s my code:

var client = document.getElementById(“name”);

if (client)
{
alert(client.nodeName);
}
else
{
alert(“Not found”);
}

I do have id called “name” inside my html h1 tag. Its an external js file, and I know the
link works.
Thanks
Lowdow

The section near the end of Chapter 2 called “Unobtrusive Scripting in the Real World” holds the key to your solution. It’s on pages 58 to 59 of the book.

Have a re-read of it and see if you can work out if the html body is available when your code is being run.

I feel a little bit silly for not remembering that!

Thanks a lot for your quick repsonse!

It seems to be the most common issue that comes up about that book, so it’s likely to receive a better treatment if a version 2 of the book is every put together.
