jquery browser change event

jQuery is a popular JavaScript library that provides many useful functions and methods that simplify manipulation of HTML documents, including responding to browser events. One of the browser events is the window resize event.

When the user changes the size of the browser window, certain actions can be performed, such as rearranging page elements or hiding/showing certain elements. In jQuery, you can use the resize() function to respond to window resize events.

The resize() function can be bound to a function that is automatically called when the browser window size changes. The following is the basic syntax for using the resize() function:

$(window).resize(function(){
  //Code to execute when the browser window is resized
});

In this example, we bind the window's resize event to an anonymous function that will be automatically called when the window size changes.

In this anonymous function, we can write code to respond to window resize events. For example, we can use jQuery's width() and height() functions to get the size of the current browser window, and then adjust the page elements as needed.

Here is an example that when the browser window size changes, it will display the new browser window size:

$(window).resize(function(){
  var w = $(window).width();
  var h = $(window).height();
  $('#size-display').html('<p>Window size: '+w+'x'+h+'</p>');
});

In this example, we use jQuery's html() function Display the window size in an element with the ID "size-display". When the browser window size changes, the function will be called again and the displayed size will be updated.

In addition to writing code in the resize() function to respond to window resize events, you can also use CSS media queries to control the layout of page elements. Media queries are a technique in CSS (Cascading Style Sheets) that can apply different styles based on different device types and screen sizes.

Here is an example of hiding an element with the ID "resize-box" when the browser window size reaches a certain size:

@media screen and (max-width: 768px){
  #resize-box{
    display: none;
  }
}

In this example, we Use the CSS @media rule to detect whether the maximum width of the screen is less than or equal to "768px". If so, hide one of the ID elements in the resize-box.

Using resize events and media queries, you can effectively control the layout and display of page elements. In the process, jQuery can greatly simplify your code and provide many useful functions and methods to manipulate HTML documents and respond to browser events.
