Picture switching

This article introduces to you several implementation methods of onmouseover and onmouseout to move the mouse in and out to switch pictures. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

It is very common to move the mouse in and out to switch images, so let’s talk about how to implement it:

The first method, which is also the simplest one, can be implemented in html

<img  class="img lazy"  src="/static/imghwm/default1.png"  data-src="img/dongtai.png"    onmouseover="this.src=&#39;img/HBuilder.png&#39;" onmouseout="this.src=&#39;img/dongtai.png&#39;"/ alt="Several implementation methods of onmouseover and onmouseout to switch pictures when the mouse moves in and out" >

First default a picture, and then write the picture to move in and out.

The second method, js replacement

<img  src="/static/imghwm/default1.png"  data-src="img/dongtai.png"  class="lazy"  name="image1"  onmouseover="mouseOver()" onmouseout="mouseOut()" / alt="Several implementation methods of onmouseover and onmouseout to switch pictures when the mouse moves in and out" >

function mouseOver() {
	document.image1.src = "img/HBuilder.png"
}

function mouseOut() {
	document.image1.src = "img/dongtai.png"
}

Write the method of replacing the image in js and call it in html.

If you don’t use onmouseover and onmouseout, you can also write like this

<p class="bg"></p>

.bg{background: url(img/HBuilder.png) no-repeat;height: 300px;}
.bg:hover{background: url(img/dongtai.png) no-repeat;}

These three methods can achieve the effect of moving the mouse in and out of the picture. Isn’t it very simple? You can try it!
