In this article, we will learn how to loop through HTML elements without using the forEach() method.

This can be done in the following ways:

Approach 1: Using the for loop

The HTML elements can be iterated by using the regular JavaScript for loop. The number of elements to be iterated can be found using the length property. The for loop has three parts, initialization, condition expression, and increment/decrement expression. Each of the items can be accessed by using square brackets with their respective index.

Syntax:

for (let i = 0; i < elements.length; i++) {
console.log(elements[i]);
}

 Example: In this example, we will see the use of the for loop.

HTML




<!DOCTYPE html>
<html lang="en">
 
<head>
    <title>
        How to loop through HTML elements
        without using forEach() loop
        in JavaScript ?
    </title>
</head>
 
<body>
    <!-- HTML elements to iterate -->
    <p>This is paragraph 1.</p>
    <p>This is paragraph 2.</p>
    <p>This is paragraph 3.</p>
 
    <script type="text/javascript">
        // Get the elements to be iterated
        let htmlElements =
            document.getElementsByTagName("p");
 
        // Use a regular for-loop
        for (let i = 0; i < htmlElements.length; i++) {
 
            // Print the current element
            console.log(htmlElements[i]);
        }
    </script>
</body>
 
</html>


Output:

output1

Output on the browser

Approach 2: Using the While loop

The HTML elements can be iterated by using a regular JavaScript while loop. The number of elements can be found using the length property. A temporary value is used to keep track of the current iteration by checking it in the condition expression. Each of the items can then be accessed by using square brackets with their respective index.

Syntax:

let i = 0;
while(i < elements.length) {
console.log(elements[i]);
i++;
}

Example: In this example, we will see the use of Using the While loop.

<!DOCTYPE html>
<html lang="en">
 
<head>
    <title>

<body>
    <!-- HTML elements to iterate -->
    <p>This is paragraph 1.</p>
    <p>This is paragraph 2.</p>
    <p>This is paragraph 3.</p>
 
    <script type="text/javascript">
        // Get the elements to be iterated
        let htmlElements =
            document.getElementsByTagName("p");
 
        // Define a variable to keep track
        // of the current iteration
        let i = 0;
 
        // Check if the current value
        // is lesser than total elements
        while (i < htmlElements.length) {
 
            // Print the current element
            console.log(htmlElements[i]);
 
            // Increment the value
            i++;
        }
    </script>
</body>
 
</html>


Output:

output1

Approach 3: Using the ‘for…..of’ statement

The for…of statement can be used to loop over values of an iterable object. It includes objects like an Array, Map, Set, or HTML elements. A temporary variable holds the current value during the execution of the loop, which can then be used in the body of the loop.

Syntax:

for (element of elements) {
console.log(element);
}

Example: In this example, we will see the use of Using the ‘for…..of’ statement.

    <script type="text/javascript">
        // Get the elements to be iterated
        let HTMLelements =
            document.getElementsByTagName("p");
 
        // Use the for...of statement to get
        // the values
        for (elem of HTMLelements) {
 
            // Print the current element
            console.log(elem);
        }
    </script>
