Steps 步骤条的最后一个节点如何根据结果动态设置

利用process-status属性值

<template>
    <div>
        <el-steps :active="active" :process-status="status">
            <el-step title="步骤 1"></el-step>
            <el-step title="步骤 2"></el-step>
            <el-step title="步骤 3"></el-step>
        </el-steps>

        <el-button style="margin-top: 12px;" @click="next">下一步</el-button>
    </div>
</template>

<script>
    export default {
    
    
        data() {
    
    
            return {
    
    
                active: 0,
                status: 'success',
            };
        },

        methods: {
    
    
            next() {
    
    
                if(this.active<2){
    
    
                this.active++;
                if (this.active == 2) {
    
    //这里可以根据实际结果判断
                    this.status = 'error';
                }
            
            }
            }
        }
    }
</script>
