通过ref修改
<div class="sub" ref="abc" @click="submit()">确定</div>
submit() {if (!this.password) {//我写的判断this.$refs.abc.style.background = "#ccc";} else {this.$refs.abc.style.background = "#07C160";}},
有的时候通过值来判断修改
<span:class="this.state==1?'active ':'active1'"@click="deviceEnableOrDisable(0)"ref="abc">正常</span><span:class="this.state==0?'active ':' active1'"style="margin-left:10px;"@click="deviceEnableOrDisable(1)"ref="abc1">停用</span>
默认state有值的情况下，有基础样式。其次在点击修改（相当于按钮样式切换的笨方法）deviceEnableOrDisable(value) {if (value == 0) {this.$refs.abc.style.background = "#52c41a";this.$refs.abc.style.color = "#fff";this.$refs.abc1.style.background = "transparent";this.$refs.abc1.style.color = "#1890ff";} else if (value == 1) {this.$refs.abc1.style.background = "#52c41a";this.$refs.abc1.style.color = "#fff";this.$refs.abc.style.background = "transparent";this.$refs.abc.style.color = "#1890ff";}},
