How to Scroll to Specific Anchors on a Web Page using JavaScript?

Navigating Web Pages to Specific Anchors using JavaScript

Navigating a web page to a specific anchor can be achieved with JavaScript by utilizing the location.hash property. Anchors are specified in HTML using the name or id attributes.

Code:

The following JavaScript code provides a simple solution to scroll the page to a given anchor:

function scrollTo(hash) {
    location.hash = "#" + hash;
}

Copy after login

Usage:

This function takes a single parameter, hash, which corresponds to the name or id of the anchor. Calling scrollTo('anchorName') will scroll the page to the element with the specified anchorName.

Example:

In the following HTML structure:

<html>
<body>
    <a name="section1">...</a>
    <a name="section2">...</a>
</body>
</html>

Copy after login

Calling scrollTo('section2') would smoothly scroll the page to the section with the section2 anchor. This mimics the effect of directly accessing the URL http://server.com/path#section2, ensuring the anchor is visible near the top of the page.

Note:

This method does not require jQuery or any additional libraries and works effectively on various browsers.
