Javascript JS file
Hello expert,
Need to use an external JS file to write to a file.
Made an HTML file and JS file to discover how to connect.
FIles below.
Used the document. write method before but have been told that
the document.write is old fashioned and that document.getElementById with innerHTML
is the way to go. So in the HTML file I did ocument.getElementById with innerHTML
method using cmsDateTime to write to the page.
Then the same method was used to write from the JS file to the HTML file
using cmsDateTime2 to write to the page but no luck.
Thought that perhaps the function writeDate in the JS file needed to be called from within
the HTML page to get the definition of cmsDateTime2 into memory. Tried calling
writerDate two ways but no luck.
Why will the div id in the HTML page not see the definition in the JS file?
Thanks.

Gary,
The file should write
'LHP Hospital Group' from the element id
'cmsDateTime within the HTML.
There is also a second div
with id 'cmsDateTime2' which is defined
in the JS file 'LHP Hospital Group Collaboration'
The first string, 'LHP Hospital Group', writes
the second 'LHP Hospital Group Collaboration'
does not.
Thanks.

Hello Gary,
Thanks for your help.
I see it writing to
<div id = "cmsDateTime"></div>
but the text for
<div id = "cmsDateTime2"></div>
does not appear.
Sorry if the explanation was not clear.
The writing of 'LHP Hospital Group Collaboration'
is the issue. If the 'cmsDateTime' can be used
in the script to write to the div with id 'cmsDateTime'
why will the script in the external file not write
to the div with id 'cmsDateTime2'.
I think it may be because innerHTML is a DOM object
so using it in an external JS file does not make
the cmsDateTime2 attribute available?
Is that right. If so how to get cmsDateTime2
into the page HTML?
Thanks
Allen

Sometimes it's easier to "conquer JavaScript" with jQuery. It's a framework that implements the good parts of JavaScript in a sensible and cross-browser-compatible manner. This script waits for your click, but it would be just as easy to make the document.ready() load these divs immediately if that is what you want.

Thanks for the points. If you're interested in loading the divs from an external script, jQuery + AJAX is the usual solution. This article shows the "hello world" exercise.
