JQuery Set Title

Introduction

Setting the title of a webpage dynamically using JavaScript can be achieved easily with the help of jQuery. In this article, we will explore how to set the title of a webpage using jQuery and provide code examples to illustrate the process.

Prerequisites

Before we dive into the code, make sure you have included the jQuery library in your HTML document. You can include it by adding the following code in the <head> section of your HTML document:

<script src="

The `title` attribute

The title attribute is a commonly used attribute in HTML that specifies extra information about an element. It is primarily used to provide additional context or a tooltip for an element when the user hovers over it. However, we can also use this attribute to set the title of the webpage dynamically using JavaScript.

Setting the title using jQuery

To set the title of a webpage using jQuery, we can simply target the title attribute of the <title> element and update its value. Here's an example:

$("title").text("New Title");

In the above code, we are using the jQuery selector $("title") to select the <title> element. We then use the text() method to update the text content of the selected element and set it to "New Title". This will effectively change the title of the webpage to "New Title".

Example Usage

Let's consider a scenario where we want to update the title of the webpage to include the current date and time. We can achieve this by combining JavaScript's Date object with jQuery.

$(document).ready(function() {
  var currentDate = new Date();
  var formattedDate = currentDate.toLocaleString();
  $("title").text("Current Date and Time: " + formattedDate);
});

In the above example, we are using the $(document).ready() function to ensure that the code is executed only after the document has finished loading. We create a new Date object and format it using the toLocaleString() method. Finally, we set the title of the webpage to include the current date and time.

Conclusion

Setting the title of a webpage dynamically using jQuery is a straightforward process. By targeting the title attribute of the <title> element and updating its value, we can easily modify the title to suit our needs. In this article, we explored the basic usage of jQuery to set the title and provided an example of updating the title to include the current date and time.

Remember to include the jQuery library in your HTML document and use the code examples provided as a starting point for your own implementations. Happy coding!
