I have a script that I am working on for an intranet tool and in this
script I have a form, which when submitted the onSubmit command calls
calculate(). In this calculate function, I have it do some calculations
and write out a new document using document.write(). One of the lines
it writes is (the whole script is at the bottom of this email).
pageData = PageData+"<b>Patient Data</b><br>Wt: "+weight+"
"+weightUnits+"    Ht: "+height+"in    Gender:
"+gender+"<br><a href=\"index.html\">Back To Form</a>";
When I click on this link to "reload" the page and have the original
form show up again, it works but in the javascript console i get errors
saying:
-The link to
file:///C:/Server/Apache%20Group/Apache2/htdocs/heparin/index.html was
blocked by the security manager.
Remote content may not link to local content.
-Error: uncaught exception: Load of
file:///C:/Server/Apache%20Group/Apache2/htdocs/heparin/index.html denied.
The basic goal of the link is to destory the page that was written by
the funtion and to just display the form again.
I am not a computer programmer by training, so maybe I am going about
this wrong. Please let me know how to get rid of these error messages.
If you have any other tips on things that I am doing strange in this
script, let me know. I am fairly familier with java and PHP, but this
is my first real dealings with javascript.
Thanks,
Andrew V. Romero
