vue.js 实现点击div标签时改变样式
作者：吴小花的博客
这篇文章主要介绍了vue.js 实现点击div标签时改变样式，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
1.点击某一项后样式发生改变(循环列表的每一项的样式改变)
效果图
v-for循环展示productType中的数据
：class动态绑定样式表中.changeStyle的样式，将当前索引传递给changeSelectStyle
@click点击事件触发函数changeStyle(),并将当前索引传递进去。
<ul v-for="(item,index) in productType" :key="index">
<li class="type-name" :class="{changeStyle:changeSelectStyle == index}"
@click="changeStyle(index)" >{{item.name}}</li>
</ul> data(){
return{
changeSelectStyle:'',
productType:[
{"name":"APE1"},
{"name":"APE2"},
{"name":"APE3"},
{"name":"APE4"},
]
}
}样式表：
.type-name
height 38px
text-align center
line-height 38px
.changeStyle
color #0099cc
background-color #fffchangeStyle方法：
让changeSelectStyle的值为当前索引的值
changeStyle:function(index){
this.changeSelectStyle = index;
},2.切换样式应该是v-bind很常用的功能(单标签样式的改变)
<div class="selectAll" :class="{selectAll: !isshow,changeSelectAll: isshow}" @click="isshow=!isshow">
<div class="text-header">全部</div>
<div class="sel-icon"></div>
</div> data(){
return{
isshow: true
}点击后改变文字颜色和图标
.selectAll
flex 0 0 37px
display flex
.text-header
padding-left 23px
flex 0 0 240px
border-left 1px solid #0099cc
border-bottom 1px solid #f7f7f7
letter-spacing 2px
line-height 37px
.sel-icon
flex 1
bg-image('../images/select-icon2')
background-repeat no-repeat
background-size 16px 16px
width 16px
height 16px
align-self center
.changeSelectAll
color #0099cc
.sel-icon
bg-image('../images/select-icon1')原图及点击后效果
3.实现联动（完整代码）
效果如下：
默认状态，循环列表的每一项都没有被选中。 选中后其中某一项 全部取消， 选中全部，其他项取消选中。
