hop of those help? Finally I got the fully answer and some help from @gopalyadav
Here is my HTML code
<tr class="frmline">
    <td width="19%">Enter Message: </td>
    <td width="22%" colspan="2"><textarea name="txtmsg" id="txtmsg" style="margin-right: 25px; width: 250px; height: 150px;resize:none;" rows="10" cols="20"></textarea> <span id="totalchar">620</span>/<span id="countBody">0</span>*
    </td>
  </tr>
 <tr class="frmline">
    <td width="19%">Allow Unicode: </td>
    <td width="22%"><input type="checkbox" name="allowunicode"  id="allowunicode" /></td>
    <td width="59%">&nbsp;</td>
  </tr>
var countedTextBox = document.getElementById("counttxt");
        var check1 = document.getElementById('allowunicode');
        var limitVal = document.getElementById('totalchar');
        var textArea1 = document.getElementById('txtmsg');
        var charEntered = document.getElementById('countBody');


        check1.addEventListener('click', () => {
          if (check1.checked) {
            limitVal.innerHTML = '268';
            checkMaxLimit(268);
          } else {
            limitVal.innerHTML = '620';
            checkMaxLimit(620);
          }
        });

        function checkMaxLimit(limit) {
          if (textArea1 && textArea1.value.length > limit) {
              textArea1.value = textArea1.value.substring(0, limit);
            alert('Sorry! You have reached your maximum message limit.');
          }

        }

        textArea1.addEventListener('keyup', () => {
          var chhhr = textArea1.value.length;
          checkMaxLimit(+limitVal.innerHTML);
          if (chhhr.value >= limitVal) {
            //alert('Maximum value reached');
            charEntered.innerHTML = limitVal.innerHTML;
          }else{
          charEntered.innerHTML = textArea1.value.length;
          }

    });

Does Postgresql varchar count using unicode character length or ASCII character length?


Tag : postgresql , By : Ben Brown
Date : March 29 2020, 07:55 AM
seems to work fine The length limit imposed by varchar(N) types and calculated by the length function is in characters, not bytes. So 'abcdef'::char(3) is truncated to 'abc' but 'a€cdef'::char(3) is truncated to 'a€c', even in the context of a database encoded as UTF-8, where 'a€c' is encoded using 5 bytes.
If restoring a dump file complained that 'Mér' would not go into a varchar(3) column, that suggests you were restoring a UTF-8 encoded dump file into a SQL_ASCII database.
create schema so4249745;
create table so4249745.t(key varchar(3) primary key);
insert into so4249745.t values('Mér');
pg_dump -f dump.sql --schema=so4249745 --table=t
createdb -E SQL_ASCII -T template0 enctest
psql -f dump.sql enctest
psql:dump.sql:34: ERROR:  value too long for type character varying(3)
CONTEXT:  COPY t, line 1, column key: "Mér"

textarea character limit by Javascript & PHP

wish helps you You have to convert line breaks first. In JavaScript, a line break is a single newline character. When it is sent, there are two. You can normalize them:
$textarea = $_POST['textarea'];
$textarea = str_replace("\r\n", "\n", $textarea);
$textarea = str_replace("\r", "\n", $textarea);

I wish this helpful for you The variable textarea is not present in the function's scope, you can refere to it with the this keyword
function textareaLengthCheck() {
    var length = this.value.length;
    var charactersLeft = 500 - length;
    var count = document.getElementById('count');
    count.innerHTML = "Characters left: " + charactersLeft;
}

javascript prevent copy/pasting beyond character limit in textarea


Tag : javascript , By : Pepe Araya

I think the issue was by ths following , Listen for the onpaste event. Once the event fires, grab the text from the clipboard and manipulate it how you like.
HTML
<textarea id="test" maxlength="10" class="maxtext"></textarea>
var test = document.getElementById("test");

test.onpaste = function(e){
    //do some IE browser checking for e
    var max = test.getAttribute("maxlength");
    e.clipboardData.getData('text/plain').slice(0, max);
};

help you fix your problem So I've created my textarea here: , this is not a string, so this should fail:
$(this + ' > .chars span')
$('.chars span', this.parentNode)
$(this).parent().find('.chars span')
