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!

Form Submitted via OnKeyPress when Enter Key Pressed

Asked by craigdawson in JScript, Internet Explorer Web Browser

Tags: enter, key, firefox, form, onkeypress

I have a form that I want to submit when the user presses Enter. The action URL is determined when the form is submitted based on what the user has selected from a dropdown. In IE, the form is being submitting twice. This is causing a problem on the server side. In Firefox, the form is submitted only once and everything works as expected. How can I code this so IE will only submit the form once? Code below.

<INPUT type="text" name="CONTRACT_ID" onkeypress="javascript:submitOnEnter(event)">

<SCRIPT>
    function submitOnEnter(e) {
            var ENTER_KEY = 13;
            var code = "";
      
            if (window.event) // IE
            {
                code = e.keyCode;
            }
            else if (e.which) // Netscape/Firefox/Opera
            {
                code = e.which;
            }
            
            if (code == ENTER_KEY) {
                doSubmit();
                return false;
            }
      }

  function doSubmit() {
      // omitted logic that sets the action on the form based on the selected option
      document.frmSearch.submit();
  }

</SCRIPT>
