HTML Maxlength Attribute Not Working on Chrome and Safari

HTML maxlength attribute not working on chrome and safari?

Use the max attribute for inputs of type="number". It will specify the highest possible number that you may insert

  <input type="number" max="999" />

if you add both a max and a min value you can specify the range of allowed values:

  <input type="number" min="1" max="999" />

See this example

EDIT

If, for user experience, you would prefer the user not to be able to enter more than a certain number, use Javascript/jQuery, as seen in this example

maxlength ignored for input type=number in Chrome

From MDN's documentation for <input>

If the value of the type attribute is text, email, search, password, tel, or url, 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">

why is input type=number maxlength=3 not working in Safari?

I've accomplished it with:

<input class="required" id="field" type="text" maxlength="3" pattern="([0-9]|[0-9]|[0-9])" name="cvv"/>

and then in JavaScript I prevented the letters:

$("#myField").keyup(function() {
    $("#myField").val(this.value.match(/[0-9]*/));
});

Default value of maxLength input in different browsers

I don't know for sure, but I believe that if no maxlength is set on the input, the default is actually unlimited. This is then applied by the browser and is specific to the platform. The W3schools link mentions 512KB as the maximum but that was presumably a value applied by specific browsers.

Edit: just checked https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/text and correctly there is no default maxlength, so Chrome and Edge are reporting that correctly.
