Steps to configure the character count feature for textarea input

How can I create a word counter for a textarea with specific width and height, ensuring that the maximum number of words typed in the textarea does not exceed 100?

HTML

<div class="input-box">
    <textarea name='textArea' id='textAreaId'></textarea>
    <div class="word-counter">0/100</div>
</div>

CSS

.input-box {
    width:500px;
    border: 1px solid red;
    position:relative;
    display:table;
}
textarea {
    width:500px;
    height:80px;
    padding-bottom: 20px;
}
.word-counter {
    position:absolute;
    bottom: 0;
    right:0;
}

Answer №1

Implement .keyup() to track letter count.

$('#area').keyup(function(){
    $('.word-counter').text($.trim(this.value.length)+'/100');
})

Additionally, utilize the maxlength attribute to set a maximum letter limit.

<div class="box">
<textarea name="" id="area" maxlength="100"></textarea>
<div class="word-counter">0/100</div>
</div>

*Please note: This functionality takes spaces into account as well. If you want to exclude spaces from the letter count, you can modify the keyup() method accordingly.

$('#area').keyup(function(){
    $('.word-counter').text(this.value.replace(/ /g,'').length+'/100');
})

Instead of using the maxlength attribute, consider implementing JavaScript to set a word limit on your textarea rather than just a character limit.

In my case, I usually set the character limit to around 1,000 characters or however much space I want the comment box to expand in height.

HTML Example:

<div class="comment-box">
<textarea name="" id="" maxlength="50"></textarea>
<div class="word-counter">0/100</div>
</div>

To utilize a function to count words, use this method:

function calculateWordCount(input){
  var wordCount = 0;
  input=input.trim();
  for (var i = 0; i <= input.length; i++) {
     if (input.charAt(i) == " ") {
         wordCount ++;
      }
  }
  return wordCount;
}
