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!

Set onclick event with javascript when duplicating table row

Asked by pwtucker in JavaScript

Tags: , , ,

Hi Experts,
I need some more help.  I have a table with 4 columns and when the user clicks on a button it duplicates the first row.  However, I need to change the onclick event of the new row to be onclick="selectTime(this,field[nextrownumber])".  The problem is that when the new field is created it increases the number at the end of each field, so the copied onclick event is not working correctly.   How can I create this onclick event ("selectTime(this,txtStartTime1)") so that txtStartTime1 becomes txtStartTime[newrownumber]?

Here is the code I am using to create the new row.  The function selectTime is in a referenced js file if that makes a difference.


    <script language="JavaScript" src="js/timepicker.js"></script>

<script language="JavaScript">

function AddRow()
    {                  
            var dColor = '#E5E5E5';  
            var eColor = '#FFFFFF';                      
            var idImg=["deleteStart","StartImg","StopImg"];
            var idText=["chkSelectStartTime","txtStartTime", "txtStopTime", "txtStartStopComments"];            
            var tbl = document.getElementById('StartStop');  
            var ctr = tbl.rows.length;
            if(tbl.rows.length == 7)
            {
                alert("Not allowed to enter more start/stop times to this time sheet.  Please submit this timesheet and create another for more records.");
                return false;
            }
            var tbd = tbl.getElementsByTagName('tbody')[0];
            var r = tbl.getElementsByTagName('tr');
            var c = r[1].cloneNode(true)
           
            var sel = c.getElementsByTagName('img');
            for(var i = 0;i<sel.length;i++)
            {                          
              sel[i].name = idImg[i] + ctr;
              sel[i].id = idImg[i] + ctr;
              if(sel[i].name == 'chkSelectStartTime' + ctr)
                {
                    sel[i].disabled = false;
                    sel[i].alt = "Click icon to delete row.";
                    sel[i].style.backgroundColor = eColor;
                    sel[i].style.cursor = 'hand';                    
                }                                                        
            }

            var sel = c.getElementsByTagName('input');
            for(var i = 0;i<sel.length;i++)
            {                  
                  sel[i].disabled = false;
                  sel[i].name = idText[i] + ctr;
                  sel[i].id = idText[i] + ctr;
                  sel[i].value = "";                                    
            }

            tbd.insertBefore(c,tbl.rows[tbl.rows.length - 1]);
    }
