Sometimes the task is to count the number of words entered in an input box or text area. If we want to display multiple lines of text, we usually use a text area. When entering text into a text area, users can use spaces as separations between words or between lines. This article demonstrates the process of counting words in input text using HTML and javascript code and the Jquery library. This is illustrated using two different examples. In the first example, the input spaces or newlines are counted to find the word count. In the second example, first replace line breaks with simple spaces and then use text splitting to split the text by spaces to find the word count.
Example 1: Use HTML and JavaScript code to find the word Count
by counting spaces and newlines in textCode design steps
Step 1 - Create an HTML file and start writing code.
-
Step 2 - Make three
tags. Given different ids. One of them will display text. The second one will show the word count. The third one will show the number of characters.
Step 3 - Create a function and start counting the number of characters in the input text using a for loop within it. Checks to see if spaces or newlines have been entered, and then increments the word count.
Step 4 - Create a button and call the above function when the button is clicked.
Step 5 - Execute the program to verify the results.

}
var characterCount = 0;
var wordCount = 1;
var nn;
for (var chr = 0; chr < testString.length; chr++) {
nn=testString[chr];
characterCount=characterCount+1;
if(nn == ' ' || nn.indexOf("") != -1){
wordCount++;
}
y.innerHTML = "word Count : " + wordCount ;
z.innerHTML = "CHARACTER count : " + characterCount ;

Example 2: Find word count via text splitting method using HTML and JavaScript code
Code design steps
Step 1 - Create an html file and start writing code.
-
Step 2 - Make three
tags. Given different ids. One of them will display text. The second one will show the word count. The third one will show the number of characters.
Step 3 - Create a function and check if there is a newline character in it. Replace it with spaces. Now, split the text in space and store the parts in an array. The number of words entered in the array is the number of words.
Step 4 - A button will be created and the above function will be called when this button is clicked.
Step 5 - Run the program and display the results.
Here the words are separated and put into an array.

In this JavaScript-HTML article, we show how to count the number of words entered in a text area, using two different examples. First, a method is given to analyze the input spaces between words and the input newlines to give the word count. In the second example, the text splitting method is used on the input spaces after converting all line breaks to simple spaces.
