target blank html with code examples

The target attribute in HTML is used to specify where a link should open when clicked. The _blank value, when used in conjunction with the target attribute, tells the browser to open the link in a new window or tab.

Here is an example of how to use the target attribute with the _blank value in an anchor tag:

<a href="https://www.example.com" target="_blank">Visit Example</a>

When a user clicks on the link "Visit Example", it will open the website https://www.example.com in a new browser window or tab.

It's important to note that when you use the target attribute with the _blank value, it can be a security concern as the new window or tab is not bound by the same origin policy and can be used to phish or execute malicious scripts.

To mitigate this risk, it is best practice to add the rel="noopener" or rel="noreferrer" attribute to the anchor tag.

<a href="https://www.example.com" target="_blank" rel="noopener">Visit Example</a>

This will prevent the new window or tab from having access to the window.opener object, which can be used to navigate the original window or tab.

It is also good practice to use the rel="noreferrer" attribute, it will prevent the Referer header from being sent to the new window.

<a href="https://www.example.com" target="_blank" rel="noreferrer">Visit Example</a>

In summary, the target attribute with the _blank value is used to open a link in a new window or tab, but it should be used with caution to prevent security issues. It is best practice to add the rel="noopener" or rel="noreferrer" attribute to the anchor tag to mitigate these risks.

Another way to open a link in a new window or tab is by using JavaScript. This can be useful in situations where you want to open a link in a new window or tab based on certain conditions or user actions.

Here is an example of how to open a link in a new window or tab using JavaScript:

<a href="https://www.example.com" onclick="window.open('https://www.example.com', '_blank');return false;">Visit Example</a>

In this example, the onclick attribute is used to call the window.open() method when the link is clicked. The first parameter of the window.open() method is the URL of the link, and the second parameter is the _blank value, which tells the browser to open the link in a new window or tab. The return false; is added to prevent the link from following the URL and refreshing the current page.

It's important to note that the window.open() method can also be used to specify the size and features of the new window or tab. For example, you can use the height, width, left, top, toolbar, and location properties to customize the new window or tab.

<a href="#" onclick="window.open('https://www.example.com', '_blank', 'height=500,width=500,left=200,top=200,toolbar=0,location=0');return false;">Visit Example</a>

It's important to note that some browsers will block pop-ups that are not triggered by user interaction and also it's a best practice to ask the user before opening a new window with JavaScript.

Another important consideration when using JavaScript to open new windows or tabs is that it can be blocked by browser pop-up blockers. This can be avoided by using a technique called "pop-up under" which opens the new window or tab behind the current window, making it less likely to be blocked by pop-up blockers.

<a href="#" onclick="var newWindow = window.open('https://www.example.com', '_blank');newWindow.blur();window.focus();return false;">Visit Example</a>

In summary, the target attribute with the _blank value, and JavaScript's window.open() method are used to open a link in a new window or tab. The rel="noopener" or rel="noreferrer" attribute should be added to the anchor tag to mitigate security risks when using the target attribute, and it's best practice to ask the user before opening a new window with JavaScript, also consider pop-up blockers and use techniques like "pop-up under" to open the new window or tab behind the current window.
