Explore the various ways jQuery shows and hides elements

jQuery is a popular JavaScript library used to simplify interactions and animations in front-end development. One common usage is to manipulate the visibility of DOM elements. In this article, we will explore the various ways jQuery shows and hides elements.

Display Elements

First, let’s see how to display elements using jQuery. Typically, there are the following three methods:

.show()

First, we have the .show() method. This method can be called on a hidden element to show it. For example, to display an element called "myDiv", you can write:

$("#myDiv").show();

.show( speed [, easing ] [, callback ] )

In addition to the .show() method, We also have a version with parameters. Through this method, we can set the speed and easing effect of the display animation. For example, to display the "myDiv" element at "slow" speed, you would write:

$("#myDiv").show("slow");

Note that if you want to use a callback function, make sure you define it after the easing parameter.

.fadeIn()

.fadeIn( speed [, easing ] [, callback ] )

.fadeIn() method is similar to the previous method, but it is not displayed immediately element, but fade into it. This method can also take speed, easing effects, and callback parameters. For example, to fade in "myDiv" at "fast" speed, you would write:

$("#myDiv").fadeIn("fast");

.hide()

.show() method changes the element from hidden state to visible state, The .hide() method does the opposite. This method can set the element to be invisible, but it will not change the element's position or space. For example, to hide "myDiv", you can write:

$("#myDiv").hide();

.hide( speed [, easing ] [, callback ] )

.hide() method can also be used with speed , easing effects and callback parameters, similar to the .show() method. For example, to hide "myDiv" at "slow" speed, you would write:

$("#myDiv").hide("slow");

.fadeOut()

.fadeOut( speed [, easing ] [, callback ] )

Similar to the .fadeIn() method, we also have a .fadeOut() method. It fades the element out and can take speed, easing, and callback parameters. For example, to fade out "myDiv" at "medium" speed, you would write:

$("#myDiv").fadeOut("medium");

Toggle element visibility

.show() and .hide() methods can be used to show respectively and hide elements, but sometimes we need to completely toggle the visibility of an element. At this time, we can use the .toggle() method.

.toggle()

.toggle( speed [, easing ] [, callback ] )

.toggle() method can switch elements between showing and hiding, i.e. if the element is shown, it will be hidden and vice versa. This method can also take speed, easing effects and callback parameters. For example, to toggle the visibility of "myDiv" and output a console message in the callback function, you would write:

$("#myDiv").toggle("fast", function() {
  console.log("Toggled visibility of #myDiv.");
});

Summary

In this article, we introduced jQuery Various methods to control the visibility of elements, including .show(), .hide(), .fadeIn(), .fadeOut(), and .toggle(). These methods provide convenient ways to create smooth interactions and animations, while also enhancing the flexibility and maintainability of front-end development.
