In daily operation, I believe many people have doubts about how to achieve mouse suspension replacement picture function in Vue.js.

Effect:

First of all, overwrite all the selected pictures on the unselected pictures.

The html code is as follows

The css code is as follows

.right {float: left; ul {margin-left: 1px; li {display: inline-block; margin-left: 12px; width: 100px; height: 100px; a {position: relative; display: inline-block; width: 100px; height: 100px; .hide _ tab {position: absolute; bottom: 0;}}

In fact, it is very simple to layout through position:absolute, and now all the pictures with selected styles have been covered by images with no selected styles.

Then you need a variable to control their visibility. This variable should be an one-to-one corresponding to each category, so this variable should not be a simple Boolean value, but a number corresponding to each classified picture.

I define this variable as active, which is declared in data

Data () {return {active: 0}}

Define a method to control the change of the active variable

ShowActive (index) {this.active = index;}

The index parameter in the method is the value passed in when the mouse is hovering

Modify the html code as follows

Pictures with selected categories are displayed only if the current index and active are equal.

When the mouse leaves, pass in a 0 that does not correspond to it, so it is not displayed.

At this point, on the "Vue.js how to achieve mouse suspension replacement picture function" on the end of the study, I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
