How to Open New Windows with Specific Dimensions and Features Using HTML and JavaScript?

Opening New Windows in HTML Using Target="_blank"

In HTML, the target="_blank" attribute tells the browser to open a new window when a link is clicked. However, this attribute does not provide control over the size or location of the new window.

For instance, consider the following code:

<code class="html"><a href="facebook.com/sharer" target="_blank">Share this</a></code>

In Firefox, this code will open the Facebook share page in a new tab instead of a new window. To achieve the desired behavior, you can utilize JavaScript to create and customize a new window.

Solution:

To open a link in a new window with specific dimensions when clicked, you can use the following code:

<code class="html"><a href="http://www.facebook.com/sharer" onclick="window.open(this.href, 'mywin', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0'); return false;">Share this</a></code>

Here's what each parameter in the window.open() function does:

• this.href: The URL of the page to open.
• 'mywin': The name of the new window.
• 'left=20,top=20': The left and top position of the window.
• 'width=500,height=500': The width and height of the window.
• 'toolbar=1': Whether to display a toolbar.
• 'resizable=0': Whether the window can be resized.

Using this approach, you can open a new window with the desired dimensions and customization options when a link with target="_blank" is clicked.
