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!

JavaScript strip alpha character from field.

Zone: JavaScript

I have field data "4.1C" or "4.1H". This alpha code lets me send the data to the proper subFields for calculation. I need to strip off the "C" or "H" to get "4.1". The evaluation works, I can send the data to the subField OK, but I can't strip off the alpha characters. (Just testing with the "C")

When I uncomment the line "mainField.replace (regExp, "")" nothing works.

==================================code
var mainField = this.getField("L1.Main.1");
var subField = this.getField("L1Su1C");
var regExp = /C/

char = (mainField.value.charAt(top1.value.length - 1 ))

switch (char) {
      case "C":
      case "c":
// mainField.replace (regExp, "")
subField.value = (mainField.value)
       break
      }
===================end code

I'm too new at this. Show me where that goes.
Thanks

From what you posted, you needed
var regExp = /C/i;

and this would have worked:
mainField.replace (regExp, "")

but note, when you replace, mainField still contains the old value. If you need the "new" value you need to "catch" the result:
mainField = mainField.replace (regExp, "")

I think this is what you want:

                       
         
           
           
             ==================================code
var mainField = this.getField("L1.Main.1");
var subField = this.getField("L1Su1C");
var regExp = /C/i; 
char = (mainField.value.charAt(top1.value.length - 1 )) 
switch (char) {
      case "C":
      case "c":
                      mainField =  mainField.replace (regExp, "")
                          subField.value = (mainField.value)
       break
      }
===================end code

hielo,
Looks good, but I only get any data to the subfield if I comment out
"mainField = mainField.replace (regExp, "")"

It sounds like your mainField is a field reference rather than a string value. Try this:

                       
         
           
           
             ==================================code
var mainField = this.getField("L1.Main.1");
var subField = this.getField("L1Su1C");
var regExp = /C/i;
 
char = (mainField.value.charAt(top1.value.length - 1 ))
 
switch (char) {
      case "C":
      case "c":
                      mainField.value =  mainField.value.replace (regExp, "")
                          subField.value = (mainField.value)
       break
      }
===================end code

I see what's going on now. And, it works. But, I need the mainField value to stay 4.1C.

I might be able to get there now, but if you see a simple rearrangement that would work, I'd appreciate it.

Thanks,

OK, then use:

                       
             switch (char) {
      case "C":
      case "c":
                     
                          subField.value = mainField.value.replace(regExp, "")
       break
      }
