如何计算Livecode中字段中的数字总和

Question

我有一个滚动字段，它的空格分隔数字和单词。

我想找到数字之和（例如：5 USA＆amp; CR 5 Uk）

Answer 1

on mouseUp
   if the field "CC" is not empty then//here "CC" is an Scrolling field and it's containing the content 
      put 0 into aa
      put fld "CC" into myData
      split myData by CR
      put the number of lines of (the keys of myData) into myArraylength
      repeat with i = 1 to myArraylength 
                put 0 into zo
         put  myData[i] into y
         split y by space
         put y[1] into searchStr
         if y[1]is not a number then
            put 0 into var1
         else
            put searchStr into vari
         put vari &comma after ss1
         end if

      end repeat
      answer ss1
      put sum(ss1) into aa1
      answer aa1
       put ss1 into second1
   split second1 by comma
   else
      answer "List is Empty"
   end if
end mouseUp

Answer 2

假设滚动字段中的文本格式一致，如示例所示：

5 USA
5 UK
4 EUR
etc.

您可以这样做：

put fld "myScrollingFld" into tList
put 0 into tTotal
repeat for each line tLineContents in tList
   put word 1 of tList into tNum
   if tNum is a number then add tNum to tTotal
end if

Answer 3

on mouseUp
  repeat for each word thisWord in fld "Myfield"
      if thisWord  is a number then add thisWord  to tSum
   end repeat
  answer tSum
end mouseUp
