html - Maxlength attribute on textarea not working for mobile -


how restrict user not enter more maxlength in text area mobile. have tried maxlength attribute not working when user select text predective text.

i want limit text in text area 300 in case of mobile responsive website.

i using chrome , firefox browsers on mobile

the maxlength attribute not stable on mobile browsers. looking @ mdn documentation attribute, find this

feature      android  firefox mobile (gecko)  ie mobile  opera mobile maxlength       ?            4.0(2.0)         no support      ?

because of volability, recommend using simple javascript. this

var textfield = document.getelementbyid("text-field");  var charcount = document.getelementbyid("char-count");    textfield.addeventlistener("keydown", function(event) {      if (this.value.length === 299 && event.keycode != 8) {          event.preventdefault();          return false;      }      var length = event.keycode != 8 ? this.value.length + 1 : this.value.length - 1;      charcount.innerhtml = (length) + " / " + "300";      charcount.style.color = length >= 270 ? "red" : "black";    });
<textarea id="text-field" rows="6" cols="30"></textarea>    <p id="char-count"></p>
