Numeric text box – max-length

[tbettinazzi@axioma.it]

I tried to use a numeric textbox with a max-length of four but  I can write how many characters I want.

Is it possible to limit the number of introduced characters in a number ?

Hi,

 

The numeric textbox has a “max” property. If you set it to 9999 and the user enters a larger number, the value will automatically reduce to 9999 when the user leaves the field.

 

If you want to fully disable entering more than 4 characters you can set: document.querySelector(‘smart-numeric-text-box input’).setAttribute(‘maxlength’, 4)

Tks for your help but I wasn’t able to apply it.

I tried

document.querySelector(‘#e18042434’).input.setAttribute(‘maxlength’, 4) but also

document.querySelector(‘#e18042434 input’).setAttribute(‘maxlength’, 4)

I can use only the id of the smart-numeric-text-box because I’ve many in the same page  with different lengths.

Could You suggest the correct expression ?

Tks

Hi,

You can try the significant digits property: https://www.htmlelements.com/docs/numerictextbox-api/#toc-significantdigits_number

It seems to be valid only for float and not for integers.

Hi,

 

The numeric textbox must be already initialized for using the maxLength attribute. Here is an example – codepen

Tks.

Just for my better understanding why did You use a timeout event to trigger the operation ?
