vue 动态样式

<p :style="{width:‘4px‘,height: ‘24px‘,background: ‘#f7ce51‘}"></p>
<p:style="{height: ‘400px‘,‘overflow-y‘: ‘auto‘,‘background-color‘: ‘#f3f3f3‘,padding: ‘15px‘}"></p>

三元运算符判断
<div :style="{ ‘opacity‘: !editableCheckNum ? 0.5 : 1 }">555</div>

动态设置class
<div :class="activeMachineId === machineItem.machineId?‘activeStyle‘:‘machineBar‘" v-for="(machineItem,machineIndex) in machineList" @click="clickMachineEvent">
    <p>{{machineItem.name}}</p>
    <p :style="machineStatusStyle(machineItem.status)"></p>
</div>


方法判断
<div class="machineBigBar machineList">
    <div class="machineBar" v-for="(machineItem,machineIndex) in processItem.machineList" :key="machineIndex">
        <p>{{machineItem.name}}</p>
        <p :style="machineStatusStyle(machineItem.status)"></p>
    </div>
</div>
