Question

What is the best way to tally up words contained within an HTML element using Javascript?

When I type or paste words into a textarea, the total number of words will be displayed at the top.

I have managed to count the words when using the element

<textarea id="text"></text>

.

However, I am unable to count the total number of words using

<div id="text"></div>

Is it feasible to calculate all the words within a

<div id="text"></div>

element?

Here is the JavaScript code for counting words:

counter = function() {
    var value = $('#text').val();

    if (value.length == 0) {
        $('#wordCount').html(0);        
        return;
    }

    var regex = /\s+/gi;
    var wordCount = value.trim().replace(regex, ' ').split(' ').length;
    $('#wordCount').html(wordCount);    
};

$(document).ready(function() {    
    $('#text').change(counter);
    $('#text').keydown(counter);
    $('#text').keypress(counter);
    $('#text').keyup(counter);
    $('#text').blur(counter);
    $('#text').focus(counter);
});

Can anyone assist me in resolving this issue?

Answer №1

The issue at hand is that when using val(), it can easily retrieve the value of a textarea. Nevertheless, this method struggles with retrieving values from a div since it lacks a value property.

To successfully fetch values from div elements, consider switching from val() to text():

var value = $('#text').text();

Here is the solution you've been looking for:

wordCounter = function() {
    var textValue = $('#text').text(); //<----replace .val() with .text()

    if (textValue.length == 0) {
        $('#wordCount').html(0);        
        return;
    }

    var regexPattern = /\s+/gi;
    var totalWords = textValue.trim().replace(regexPattern, ' ').split(' ').length;
    $('#wordCount').html(totalWords);    
};

$(document).ready(function() {    
    wordCounter(); //<---call the function at this point.
});

The function should be triggered on dom ready because all the events attached to the div require some user interaction.

Replace the val with text:

var value = $.trim($('#text').text());

When you use val, you get the attribute value, but when you use text, you get the inner text of the element (in this case a div).

Improving Efficiency

var counter = function () {
    var value = $.trim($(this).text()); // Remove leading/trailing spaces

    if (value.length === 0) {
        $('#wordCount').text(0);
        return;
    }

    var wordCount = value.replace(/\s+/g, ' ').split(' ').length;
    $('#wordCount').text(wordCount);
};

$(document).ready(function () {
    $('#text').on('change keydown keypress keyup blur focus', counter);
});
