Force email address
You want the respondent to write an e-mail address.The script needs to validate if a string input is in email address format
In order to check email address.
As a questionnaire creator
I want to validate if a string input is in email address format when the respondent writes an e-mail address.
Example
Solution
- Add a Text grid question to Questionnaire editor like below
- Go to menu Properties -> Question scripts -> Java script tab -> Input script
Code
var normalQuestionCheck = questioncheck;
function extendedQuestionCheck()
{
var valid = normalQuestionCheck();
if (valid)
{
var val;
//The value below is the index value of the sub question where your e-mail question is asked.
//In this case we use the sub question has index 2
val = document["query"][quest.label + "." + 2].value;
if (val.length > 0)
valid = validateEmail(val);
}
if (!valid)
{
alert('Wrong email address format');
return false;
}
return true;
}
questioncheck = extendedQuestionCheck;
