JavaScript is a scripting language used in the development of webpages. Originally
developed by Netscape, JavaScript enables web pages to be more animated and dynamic
in terms of graphics, layout and functionality.
When operating in a browser (the program you are viewing this page in - ie Internet
Explorer, Firefox, Netscape, Opera, Safari, etc.), JavaScript can allow much of the
activity to be conducted locally on your own machine. Hence use of a web page can
be much faster, more interactive and require less page reloading - saving on data
download quota's.
A popular example of a website that uses JavaScritpt is GMail's (Google's Email
System) web interface. GMail makes heavy use of JavaScript to present a very
complete and functional email program - all in a web page.
How Jobs4Careers Uses JavaScript
Jobs4Careers uses JavaScript throughout the website. Most commonly, we make use of
Javascript to refine out job searches - meaning we can refine job results without conducting
another search. Also, our job mapping uses JavaScript to bring you locational information
about job listings and provide further visual information about where the job is located.
Additionally, in My Account, you can access different pages without refreshing the rest
of the page.
While we encourage you to enable JavaScript for use on Jobs4Careers1, we have
made every effort to ensure that use of the site is just as operational without JavaScript
enabled as with JavaScript enabled. If for any reason you have difficulty using our
site, please let us know.
Is JavaScript Dangerous?
JavaScript has its own security model, but this is not designed to protect the
Web site owner or the data passed between the browser and the server. The security
model is designed to protect the user from malicious Web sites, and as a result, it
enforces strict limits on what the page author is allowed to do. They may have control
over their own page inside the browser, but that is where their abilities end.
JavaScripts cannot read or write files on users' computers. They cannot create
files on the server (except by communicating with a server side script that
creates files for them). The only thing they can store on the user's computer
are cookies.
They are allowed to interact with other pages in a frameset, if those frames
originate from the same Web site, but not if they originate from another Web
site (the postMessage method from the Web Applications 1.0 specification does
safely extend this capability, but I will not cover that here). Some browsers
will even treat different port numbers on the same server as a different Web
site.
JavaScript cannot be used to set the value attribute of a file input, and will
not be allowed to use them to upload files without permission.
JavaScript cannot read what locations a user has visited by reading them from
the location object, although it can tell the browser to jump back or forward
any number of steps through the browser history. It cannot see what other Web
pages the user has open.
JavaScript cannot access the cookies or variables from other sites.
It cannot see when the user interacts with other programs, or other parts of
the browser window.
It cannot open windows out of sight from the user or too small for the user
to see, and in most browsers, it cannot close windows that it did not open.
