Question

I have an html text box where I want to limit the numbers after decimal to 4.
After an operation it can be achieved using toFixed() but while the user inputs the text is there any way out.

Please guide me.

Answer 1

Did you Try a REGEX?

The Regex would look like
/^[0-9]+.[0-9]{4}$/
where {4} says that Length after . would be 4

Define REGEX:
var regex1=/^[0-9]+.[0-9]{4}$/;var yourtextfromTextBox= textBox.text();yourtextfromTextBox.match(regex1);
Try this
