Hi there,
Currently, I have an input field of type number. I want to do a check on the input field to
a: give alert if the user inputs string.
b: restrict the numbers that user can input to between 0 and 30.
Not sure how I could use JS to do this.
Regular expressions?
Hello!
Please post the code you tried.
var temp2 = Appery('numberInput').val();
var participant_number = Appery.parseInt(temp2, 10);
if(participant_number < 0 && participant_number 30){
alert("Invalid participant number. Please try again.");
}else{
Appery.navigateTo('HomeScreen', {});
}
I figured that if the input is number, then parse Int will not work.
However I get an error message in the console that says,
Post method did not succeed. 400 bad request
Looking for solution..
Any luck?
parseInt(..) should work, https://developer.mozilla.org/en-US/d...
Post method did not succeed. 400 bad request -- looks like a REST request error.
Well done, yes it is a REST error as the button also has an associated REST service associated it.
Still remains that the above code, does not give an alert as it should when a string is entered.
Please debug your code. The if-statement that you have is not correct.
