How to hide span elements in jquery (three methods)

In web design, jQuery is often used to achieve some dynamic effects. Among them, controlling the display and hiding of elements is also a common requirement. jQuery provides a variety of ways to hide span elements, and this article will introduce some of them.

1. Use the hide() method

jQuery’s hide() method can hide a specified element.

$(selector).hide();

Among them, selector is the selector of the element to be hidden. When this method is called, the element is hidden. If you want to hide the span element, you can do it with the following code:

$("span").hide();

The selector here is "span", which means to select all span elements in the page and hide them. It should be noted that if there are multiple span elements on the same page, this method will hide all span elements at the same time.

2. Use CSS methods

You can also use CSS methods to control the display and hiding of an element.

$(selector).css("display", "none");

Among them, selector is the selector of the element that needs to be hidden. "display" is the CSS property name to be set, and "none" is the property value to be set. When this code is executed, the element will be hidden. For hiding span elements, you can use the following code:

$("span").css("display", "none");

The selector here is still "span", which means it applies to all span elements.

When using this method, please note: If the element has a "display" attribute defined in the original CSS style sheet, then this method will overwrite the original style.

3. Use the toggle() method

The toggle() method is a function provided by jQuery to control the display and hiding of elements. When the passed parameter is true, the specified element will be hidden; when the passed parameter is false, the element will be displayed.

$(selector).toggle(true/false);

The selector here represents the selector of the element to be hidden or displayed. Hiding the span element can be achieved through the following code:

$("span").toggle(true);

The selector here is still "span".

If an element itself is hidden, the element will be displayed; if the element itself is displayed, the element will be hidden.

In addition to passing true/false as parameters, the toggle() method can also accept other parameters. Their uses are shown in the following table:

Parameters	Purpose
[ duration]	Specifies the speed of animation. The default value is "normal".
[callback]	Specifies the function to be executed after the animation is completed.
[queueName]	Specifies the name of the queue to use (a string).
[switchFlag]	If set to true, the animation will only be performed when the element is in its original state. Otherwise, the animation will be executed every time.

For example, you can use the following code to hide the span element:

$("span").toggle("slow");

The "slow" here means that the animation is slower and the element is hidden slowly .
