Troubleshooting JavaScript

JavaScript errors can be tough to find.  Asynchronous execution, different browser behaviors and interaction with other scripts on the page can all result in problems that occur on some browsers, or are difficult to track down.



Two ways to catch many of the most commons problems in JS are to simply make use of the JavaScript "use strict" option which works everytime you run the script.  The second, which is more labor intensive, is to use the JSLint tool.

Vortex removes the need to worry about buffer sizes and array indexes, preventing overflows. The default Vortex settings are designed to limit resource utilization when  crawling  and  searching . These can of course be changed to suit your needs. No programming language can prevent all errors, so you are encouraged to use the CWE/SANS list as a checklist when developing your application. If you have any questions about the functions that can help, for example by sanitizing input and output data, you can search our manual or call tech support.

Use id's instead of name's for anchors.  There are a couple of advantages: Any element with an id can be targeted as an anchor, and many elements you would want to be a target already have an id for CSS styling, so you can both save space, and simplify the DOM. IE8 in quirks mode can't dynamically change the name of an <a>, it will instead create a new attribute submitName, which is not targetable as an anchor.
