Check Numeric Demo
This survey demonstrates the check numeric processing that is available in the web survey facility. By default, the
Answer Type
for all questions is
Text
. However when a
Text Line
input type question has
Answer Type
set as
Numeric
, the check numeric processing is enabled for that question. When the respondent enters a non-numeric answer for that question, a Javascript window pops up to inform the respondent that the answer is not a number. If the respondent clicks on a Submit button after entering a non-numeric answer, then the same Javascript window with the same error message will appear and the
Submit action will not occur
.
