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!

Disabling ALT-F4

Asked by jarasa in JavaScript

Tags: disable, alt

Hi all.
Does anybody know a way to disable ALT-F4 key that really works without making any change to the current document or opening a new window, my code works and it disable the key but I have to display an alert and open a new window or it closes the main one. Besides if I push ALT-F4 again while the alert is open it closes the main window too, I would like to do it without making any of this things.

Tahnks in advantage

Javier

P.D.: Here is how I do it.

document.onkeydown=teclas;  

function teclas() {  

var tecla = window.event.keyCode;
var control = window.event.ctrlKey;
var alt = window.event.altKey;
var tipo=event.srcElement.type;

if (alt) {
      switch (tecla) {
            // Alt-F4
            case 115:
                  window.event.keyCode=86;  
                  window.cancelEvent=true;
                  event.cancelBubble=true;
                  event.returnValue=false;
                  event.cancel=true;
                  adios();
                  return false;  
                  break;
      }
}
}

function adios() {
             // I have to display this alert first
      alert("VEGA :: Opcion no Valida")
             // And open this window too or it wont work
      openCerrar("cerrar.jsp",400,250,null,null,'')
}
