jQuery Tutorial: How to Change How HTML Elements Display

jQuery is a popular JavaScript library that is widely used for making dynamic web pages and interactive websites. In the process of web development, we often encounter situations where we need to modify the attributes of elements. One of the common operations is to modify the display attribute value of the element. In this tutorial, we will learn how to use jQuery to dynamically modify the display attribute of an element, and provide specific code examples.

What is the display attribute

In HTML and CSS, the display attribute is used to define the display mode of an element. It determines how elements are displayed on the page, such as block-level elements, inline elements, hidden elements, etc. By modifying the value of the display attribute, the element can be hidden, displayed, or the display mode changed.

Methods to modify the display attribute of an element

In jQuery, you can use the css() method to modify the CSS attributes of an element, including the display attribute. The following is a basic example that demonstrates how to change the display attribute value of an element to "none":

$(document).ready(function(){
    $("#myElement").css("display", "none");
});

In this example, we use jQuery to select the element with the id "myElement" and display it The attribute value is set to "none", which hides the element.

Display elements

Sometimes we need to display previously hidden elements. You can set the display attribute value to "block" or "inline", depending on the original display mode of the element. The following is an example to display an element:

$(document).ready(function(){
    $("#myElement").css("display", "block");
});

Here we set the display attribute value of the element with the id "myElement" to "block" so that it can be displayed on the page.

Switch the display state of the element

In addition to directly setting the display attribute value, we can also use the toggle() method to switch the display state of the element. The toggle() method switches between showing and hiding states. The following is an example that demonstrates how to toggle the display state of an element:

$(document).ready(function(){
    $("#myElement").toggle();
});

In this example, each time the toggle() method is called, the display state of the element will switch. If the element was previously hidden, then Now it will show up and vice versa.

Summary

Through this jQuery tutorial, we learned how to use jQuery to modify the display attribute of an element to hide, show and switch the display state of the element. In actual development, this operation is often used and can effectively control the display effect of page elements.
