How to use JavaScript to achieve the finger sliding switching effect of tab content?
On the mobile side, sliding your finger to switch tab content is a common interaction method. Through JavaScript, we can easily achieve this effect and provide users with a more friendly and smooth experience.
This article will introduce how to use JavaScript to achieve the finger sliding switching effect of tab content, and provide specific code examples for reference.
First, we need a basic HTML structure to create the tab. The following is a simple example:
1 2 3 4 5 6 7 8 9 |
|
In the above example, we have a tabs
container, which contains tab labels of class tab
, and the corresponding Content. The selected tab label will have the active
class, and the content area will also have the active
class.
Next, we need to use JavaScript to achieve the effect of finger sliding switching. First, we need to detect the user's gesture event and obtain the direction and distance of the finger slide.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
|
In the above code, we use the touchstart
event to get the touch point position when starting to slide, and use the touchmove
event to calculate the distance of the finger slide in real time .
Next, we need to switch tabs based on the distance of the finger slide. We can decide whether to switch to the next or previous tab by calculating the percentage of the sliding distance.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
|
In the above code, we set a threshold threshold
to determine whether the sliding distance is enough to switch to the next or previous tab. When the sliding distance is greater than the threshold, the switchToTab
function is called according to the sliding direction to switch tabs.
Finally, we also need to implement the switchToTab
function to truly realize the tab switching effect.

|
In the above code, the switchToTab
function will decide to switch to the next or previous tab based on the direction parameter passed in. First, you want to get the currently active tab and content, then get the next tab and content based on the direction parameter passed in. Finally, toggle the visibility of tabs and content by adding or removing the active
class.
Through the implementation of the above code, we can easily achieve the finger sliding switching effect of tab content.
Summary:
By using JavaScript, we can easily achieve the finger sliding switching effect of tab content. First, obtain the direction and distance of the finger slide by detecting gesture events. Then, determine whether to switch tabs based on the sliding distance. Finally, toggle the visibility of tabs and content by adding or removing the active
class.
