Although jQuery itself cannot directly modify the web page title, the same effect can be easily achieved using pure JavaScript. The following JavaScript code snippet can modify the full title of the current web page (i.e. the title displayed in the browser title bar):

document.title = '新的標(biāo)題';

FAQs (FAQs) on using jQuery to modify page titles

How to use jQuery to modify the title of a specific page?

To use jQuery to modify the title of a specific page, use the document.title attribute. This property allows you to get or set text in the title bar. Here is a simple example:

$(document).ready(function(){
  document.title = "新的頁面標(biāo)題";
});

code, "New Page Title" is the new title you want to set. This code should be placed inside the <script></script> tag in the HTML file.

How to use jQuery to dynamically modify page title?

Yes, you can use jQuery to dynamically modify the page title. This is useful in situations where titles need to be updated based on user interaction or other events. For example:

$(document).ready(function(){
  $('#button').click(function(){
    document.title = "新的頁面標(biāo)題";
  });
});

In this code, when the user clicks on an element with id "button", the page title will be changed to "New Page Title".
