需求如下:三个盒子,click改变图片、文字颜色、背景颜色。hover改变图片和文字颜色,两个事件的两张图片是不一样的。 其中click点击之后下面展示不同内容。
思路:data里的每个数据都有绑定一个id。
click绑定事件, @click="clickHandle(item.id)",给一个变量等于当前的元素的id来控制color,background-color,img。点击展示不同内容可以用v-if="isChecked == 0" v-else-if="isChecked == 1"来控制。
vue里没有hover事件,用mouseenter,mouseleave来模拟,@mouseenter="isHover = item.id", @mouseleave="isHover = -1"。再写一个变量等于当前的元素的id来控制img地址的变化。hover改变文字颜色可以用css来控制li:hover {color: #dc2828;}。
比较复杂的是img,需要用两次双目表达式,先判断是否是是click状态,再判断是否是hover状态。
data和methods:
data() {
return {
listData: [
