When utilizing ng-model binding in an input field, data is usually stored as a string. Is there a way to verify if the user has entered a number?
When utilizing ng-model binding in an input field, data is usually stored as a string. Is there a way to verify if the user has entered a number?
Utilize the angular IsNumber functionality,
if (angular.isNumber(modelvar) {
}
Implement validation for the input field to restrict input to only numbers,
Restrict typing numbers in a textbox only
Alternatively, consider utilizing a validation engine to validate inputs and display warning messages.
If you want to make sure a value is a number in HTML, use the following code:
<input type="number">
To verify that it is indeed a number in Angular, you can do the following:
if(typeof(VARIABLE) !== "number"){
console.log("Error: The variable is not a number");
return;
}
I hope this information proves useful!
