＜ elementUI组件样式及功能补全： 实现点击steps组件跳转对应步骤 ＞

---

👉 前言

在 Vue + elementUi 开发中，elementUI中steps步骤条组件只提供了change方法，并未提供各个步骤的点击跳转方法。在实际项目使用中，如果步骤条并非一步一步进行，而是有步骤跳转。那么就需要自己去自定义DIY了。

接下来，简单阐述下，开发中使用方法！

👉 一、效果演示

话不多说，先上效果图！ 白嫖万岁！当然，如果有帮助，希望不要吝啬你的点赞呀！

👉 二、点击steps跳转效果实现

通过为 el-step 添加 @click.native 属性，拦截标签原生点击事件！

注意：在vue3中 ‘.native’ 修饰符在vue3中被弃用了，
解决方法：把 ‘.native’ 换成 ‘.enter’

👉 三、实现案例

> HTML模板

<template>
<div class="stepBox"><div :class="'step-line' + (stepStatuList['开展整改'] ? ' isSuccess' : '')"></div><span :class="'el-icon-caret-top point num_'+ active"></span><el-steps:active="active"align-centerfinish-status="success"@change="stepChange"><el-steptitle="开展核实":status="active == 0 ? 'success' : stepStatuList['开展核实'] ? 'process' : 'wait'"@click.native="stepStatuList['开展核实'] ? stepClick(0) : () => {}":style="{cursor: (stepStatuList['开展核实'] ? 'pointer' : 'not-allowed')}"></el-step><el-steptitle="核实审核":status="active == 1 ? 'success' : stepStatuList['核实审核'] ? 'process' : 'wait'"@click.native="stepStatuList['核实审核'] ? stepClick(1) : () => {}":style="{cursor: (stepStatuList['核实审核'] ? 'pointer' : 'not-allowed')}"></el-step><el-steptitle="开展整改":status="active == 2 ? 'success' : stepStatuList['开展整改'] ? 'process' : 'wait'"@click.native="stepStatuList['开展整改'] ? stepClick(2) : () => {}":style="{cursor: (stepStatuList['开展整改'] ? 'pointer' : 'not-allowed')}"></el-step><el-steptitle="整改审核":status="active == 3 ? 'success' : stepStatuList['整改审核'] ? 'process' : 'wait'"@click.native="stepStatuList['整改审核'] ? stepClick(3) : () => {}":style="{cursor: (stepStatuList['整改审核'] ? 'pointer' : 'not-allowed')}"></el-step></el-steps></div>
</template>

> Js模板

stepClick(step) {this.active = step// this.stepChange(step)
},
// 步骤切换
stepChange(step) {this.multipleSelection = []this.toggleSelection([])this.$refs['params'].resetFields();this.$router.push({query:merge(this.$route.query,{'active':step})})this.getStepById()// if(step == 1) {//   this.detailListType = '-1'// } else {//   this.detailListType = '0'// }this.detailListType = '0'this.getColumnArray(() => {if((step === 0 || step === 2) && this.tableData.length === 0) {this.detailListType = '1'this.getColumnArray()}})
},
