How can I check if a variable contains a number instead of text?

if (checkVar contains a number){
action}
else{
action}

e.g.
var checkVar = 10052367A
will give a false result
var checkVar=125894
will giva a false result
var checkVar=ABC
will give a true result

Thanks in advance

Hi,

Thank you for your enquiry.

I'm sure there is an easier way of achieving this, but the following script actions should hopefully suffice.



where input is the variable you are trying to check. You can obviously replace the first Debug.trace() function with whatever actions you want to take place when the string contains numerical values, and replace the second Debug.trace() function with the actions that should occur when the variable contains no numbers.

Kind regards,

Here is another way of doing it:

Result would be a variable in your Opus publication that might be in a popup box to indicate to your user that numbers are not valid. One other thing I was thinking about is, could you not just specify if you are using an input field not to use numbers?


var iChars = "0123456789"

for (var i = 0; i < test.length; i++)
{
if (iChars.indexOf(test.charAt(i)) == -1){
result="All letters";
}
else {
result="You have a number here.";
}
}

Both are working like a charm...
Thank you
