How to check if number is numeric while using jquery 1.7+? : jquery mobile

Answer Posted / Santosh Kumar Tyagi

You can use the jQuery `isNumeric()` function to check if a string is a number. Here's an example:

```javascript
function isNumeric(num) {
if (typeof num !== 'string') return false;
return !isNaN(parseFloat(num)) && isFinite(num);
}

// Usage
if (isNumeric($.trim(inputValue))) {
// Number is valid
} else {
// Number is not valid
}
