The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

stop function on null

Asked by thatelvis in JavaScript

Hello,

I am trying to use this md5 code from the link below

http://pajhome.org.uk/crypt/md5/instructions.html

I have it working ok when a user submits my form

<form action="<%=MM_editAction%>" name="RegisterUser" method="POST" onsubmit="aPassword.value = hex_md5(aPassword.value)">


BUT, my problem is if the user does not enter it still creates a unique number, how can I force the script not to create a value null.

http://www.theelbow.com/hello.asp

if you see on this page , when you click the i agree button, with out putting anything in the textfield you will see it populate for a moment. I want it not to do this.

I believe the function I need to change is

function hex_md5(s){ return binl2hex(core_md5(str2binl(s), s.length * chrsz));}

what can I do with that to only work when it is passed a value greater then 0 or a non null value.



regards and am grateful for any help

kenny
