  • Debugging Javascript
    6803.book Page 451 Thursday, June 15, 2006 2:24 PM APPENDIX ■ ■ ■ Debugging JavaScript In this appendix, I will introduce you to some tricks and tools to debug your JavaScript code. It is very important to get acquainted with debugging tools, as programming consists to a large extent of trying to find out what went wrong a particular time. Some browsers help you with this problem; others make it harder by having their debugging tools hidden away or returning cryptic error messages that confuse more than they help. Some of my favorites include philo- sophical works like “Undefined is not defined” or the MSIE standard “Object doesn’t support this property or method.” Common JavaScript Mistakes Let’s start with some common mistakes that probably every JavaScript developer has made during his career. Having these in the back of your head when you check a failing script might make it a lot quicker to spot the problem. Misspellings and Case-Sensitivity Issues The easiest mistakes to spot are misspellings of JavaScript method names or properties. Clas- sics include getElementByTagName() instead of getElementsByTagName(), getElementByID() instead of getElementById() and node.style.colour (for the British English writers). A lot of times the problem could also be case sensitivity, for example, writing keywords in mixed case instead of lowercase. If( elm.href ) { var url = elm.href; } There is no keyword called If, but there is one called if. The same problem of case sensi- tivity applies to variable names: var FamilyGuy = 'Peter'; var FamilyGuyWife = 'Lois'; alert( 'The Griffins:\n'+ familyGuy + ' and ' + FamilyGuyWife ); This will result in an error message stating “familyGuy is not defined”, as there is a variable called FamilyGuy but none called familyGuy.

    mozilla development roadmap Brendan Eich, David Hyatt table of contents • introduction • milestone schedule • about ownership... • a new • current release • what all this does not roadmap status mean • discussion • how you can help • application architecture • summary • project • to-do list rationale management introduction Welcome to the Mozilla development roadmap. This is the third major roadmap revision, with a notable recent change to the status of the integrated Mozilla application suite, since the original roadmap that set Mozilla on a new course for standards compliance, modularity, and portability in 1998. The previous roadmap documented milestones and rules of development through Mozilla 1.3, and contains links to older roadmaps. Most of this document reflects the new application architecture proposal made last year. The effort resulting from that proposal has finally borne fruit, or to mix metaphors, hatched new application creatures: Firefox and Thunderbird. The new, significant roadmap update hoped for early in 2004 has been postponed. See Brendan's roadmap blog for thoughts that may feed into it. An interim roadmap update focused on the "aviary 1.0" 1 From www.mozilla.org/roadmap.html 4 August 2004 releases of Firefox 1.0 and Thunderbird 1.0, and the 1.8 milestone that will follow, is coming soon. We have come a long way. We have achieved a Mozilla 1.0 milestone that satisfies the criteria put forth in the Mozilla 1.0 manifesto, giving the community and the wider world a high-quality release, and a stable branch for conservative development and derivative product releases. See the Mozilla Hall of Fame for a list of Mozilla-based projects and products that benefited from 1.0.
