Sum of variable

#1 · April 23, 2020, 11:15 pm

If we have a set of NumbericInput respectively with variable :[h1],[h2],[h3],.....[h10]

Now, what is the best approach to sum all of input without error.(even some input be empty):

I try like this:

........i set this code for page-enter.....
Loop 1 10 [i]
     SetCompVar [h[i]] 0
endloop



........and this code for totol button.....
setvar [sum] 0
Loop 1 10 [i]
   GetCompVar [result] [h[i]]
   Math "[sum]+[result]" 0 [sum]
endloop

Is there any better way to perform this task (without filling zero in page-enter )?

a) Remove the code in the page-enter section.

b) try this code for the Total Button ...

setvar [sum] 0
... next command for testing only
setVar "[resultTypes]" ">>> "
....................................................
Loop 1 10 [i]
GetCompVar [result] [h[i]]
TypeOf [result] [resultType]
... next command for testing only
SetVar "[resultTypes]" "[resultTypes][i]=[result];[resultType] .. "
If [resultType] = "number"
   Math "[sum]+[result]" 0 [sum]
EndIf
endloop
.. show test results
AlertBox "resultTypes" "[resultTypes]" ""
...................................................

... once tested, you can remove/comment out the commands for testing.

P.S. very considerate of you to include a .neoapp file with just the objects related to the issue ... avoids translation misunderstandings, allows for focus on issue at hand, and quick try outs on my part ... thanks.

As an old Neobooker, I am used to using Setvar "[thisvar]" "[thisvar]+[addedvalue]"

This works in the windows version but not in Web version. what is the proper way to totaling [thisvar] with additional values?

It may have been answered here but I am not clear.

If the math action is to be used what would the string look like?

Thanks

@donbwalker

Try ...

SetVar [total] 8
SetVar [thisNumber] 7
SetVar [total] [thisNumber]+[total]
AlertBox "new sum ..." "... is [total]" ""

You can overcome slight syntax differences by letting the command wizard do it for you ... just type the command and then double click on it.

Thanks Gaev,

Are you saying it is necessary to define the var before you can add them?

Currently in my situation the [total] does not exist yet.

I create the value for [thisnumber] and then try to add it to [total]

The result for [total] is NaNa

So I guess I need to setvar [total] 0 first.

I'll give it a try.

Yep that did it.

Thanks again.
