For example, we can use the following code to get the href value of an anchor element:
const link = document.querySelector('a'); const href = link.getAttribute('href'); console.log(href); // Output: "https://www.example.com"
Similarly, we can set the href value of an anchor element using the
const link = document.querySelector('a'); link.setAttribute('href', 'https://www.newurl.com');
This will set the href value of the anchor element to “https://www.newurl.com”.
Method 1: Using the getAttribute() method
You can use the getAttribute() method to obtain the href value of an anchor tag. Here’s an example code snippet to demonstrate:
const anchorElement = document.querySelector('a'); const hrefValue = anchorElement.getAttribute('href'); console.log(hrefValue);
Method 2: Directly accessing the href property
You can also directly access the href property of an anchor tag to obtain its value. Here’s an example code snippet to demonstrate:
const anchorElement = document.querySelector('a'); const hrefValue = anchorElement.href; console.log(hrefValue);
- getAttribute(): This method can be used to get the value of any attribute on an element. In the case of anchor elements, it can be used to get the value of the href attribute.
- property: Another way to access the href value is to use the property of the anchor element. The href property holds the actual value of the href attribute.
- location.href: This method can be used to get the current URL of the page. If you want to get the href value of a clicked anchor element, you can use this method together with the click event listener.
- e.target.href: When an anchor element is clicked, the click event is triggered. By using the event object, we can get the clicked element and access its href value. This can be useful when using event delegation.
- Use event listeners to handle clicks on links with href attributes. This allows you to customize the behavior and prevent the default behavior of opening the link in a new page.
- Be mindful of relative and absolute URLs when working with href attributes. A relative URL is relative to the current page, while an absolute URL specifies the full URL of the target page. Make sure you understand which type of URL you’re working with to avoid confusion.
- Consider using the .setAttribute() method to modify href attributes dynamically. This allows you to update the target URL of a link based on user input or other factors.
- Navigation: Retrieving the href value of a link allows developers to create dynamic navigation menus or link resolvers that redirect users to different web pages based on their previous actions.
- Tracking: When tracking user behavior on a website, retrieving the href value of clicked links can help developers analyze which pages and links are most popular and optimize the user experience accordingly.
- Form validation: By retrieving the href value of a link in a form, developers can validate the input and ensure that users are submitting data to the correct destination.
- Always use the built-in methods for updating href attributes. For example, you should use the
- Be careful when concatenating strings to build an href attribute value. Make sure to properly escape any special characters that may be included in the URL. You can use the
encodeURIComponentfunction to escape any special characters within dynamic URL parameters.
- Avoid using
- When using the
window.location.assignmethod to update the current page URL, make sure to use a relative URL or a full URL including the protocol (e.g.
- Test your href attribute manipulation thoroughly across different browsers and devices to ensure that it works as expected.
- What is an href value in HTML?
- What is the difference between .href and .getAttribute(“href”)?
An href value is a property of an HTML link () element that specifies the URL of the page that the link goes to. It can also be used to link to other resources like stylesheets, scripts, or other file types.
getAttribute() method. For example, to access the href value of an element with an ID of “example-link” using the dot notation, you would use:
var hrefValue = document.getElementById("example-link").href;
To do the same thing using the
var hrefValue = document.getElementById("example-link").getAttribute("href");
Both of these methods will give you the same result: the value of the href attribute for the specified HTML link element.
The main difference between the two methods is that using dot notation will give you the absolute URL if one is present, whereas using the
getAttribute() method will give you the value exactly as it appears in the HTML code.
document.getElementById(), and then set the value of the href property using the assignment operator. For example:
document.getElementById("example-link").href = "https://www.example.com";
