How to Count Words in JavaScript
Today, we will write a program that counts the number of words in a sentence entered by the user.
Example : words counter using Javascript.
<textarea id="my-input"></textarea>
<button onclick="myFunction()">
Count Words
</button>
<script>
function myFunction(){
const myVar = document.querySelector('#my-input').value.split(' ')
alert("Total Word : "+ myVar.length)
}
</script>
Try it Yourself »
- As you can see, I have created a <textarea> with its id my-input. So that, users can enter some text in it.
<textarea id="my-input"></textarea>
- I have also created a <button> with the onclick attribute and set its value to myFunction(). So that, whenever the button is clicked, myFunction() will be called.
<button onclick="myFunction()">Count Words</button>
- Now it's time to create the myFunction() function. Inside the function, I have select the <textarea> value and split its value into an array of words using the split() method. Stored in a variable named myVar
<script> function myFunction(){ const myVar = document.querySelector('#my-input').value.split(' ') } </script>
The myVar returns an array that represents all the words. For example, if the string is How are you?, then myVar will return the following array.🔽Array 0:"How" 1:"are" 2:"you?" length:3
- As you can see in the above example, we got an array. If we target the length property, then we will also get total words.
function myFunction(){ const myVar = document.querySelector('#my-input').value.split(' ') alert("Total Word : "+ myVar.length) }
