uni 实现切换导航栏

1、实现一个简单的切换标签，显示不同内容效果。代码如下：

<template>
    <view class="warehousingToBeCon">
        <!-- nav -->
        <view class="nav">
            <view class="flex_between">
                <view class="nav_title" v-for="(item,index) in dataList">
                    <view :class="{'active':isActive==index}" @click="chenked(index)">
                        {{item.name}}
                    </view>
                </view>
            
            </view>
        </view>


        <!-- 内容模块 -->
        <view class="nav_item" v-if="isActive==0">
            模块1内容
        </view>
        <view class="nav_item" v-if="isActive==1">
            模块2内容
        </view>
        <view class="nav_item" v-if="isActive==2">
            模块3内容
        </view>
        
    </view>

</template>

<script>
    export default {
        data() {
            return {
                isActive: 0,
                dataList:[
                    {
                        index:0,
                        name:"模块1"
                    },
                    {
                        index:1,
                        name:"模块2"
                    },
                    {
                        index:2,
                        name:"模块3"
                    }
                ]
            }
        },
        methods: {
            chenked(index) {
                this.isActive = index;
            },
        }
    }
</script>
