The maxlength
attribute is not working with <input type="number">
. This happens only in Chrome.
<input type="number" class="test_css" maxlength="4" id="flight_number" name="number"/>
From MDN's documentation for <input>
If the value of the type attribute is
text
,search
,password
,tel
, orurl
, this attribute specifies the maximum number of characters (in Unicode code points) that the user can enter; for other control types, it is ignored.
So maxlength
is ignored on <input type="number">
by design.
Depending on your needs, you can use the min
and max
attributes as inon suggested in his/her answer (NB: this will only define a constrained range, not the actual character length of the value, though -9999 to 9999 will cover all 0-4 digit numbers), or you can use a regular text input and enforce validation on the field with the new pattern
attribute:
<input type="text" pattern="\d*" maxlength="4">
