前言
因为是在vue源码的基础上进行修改,所以,就没有复制代码在文章上,采取的是截图对比源码和我修改的代码片段。要麻烦你们自己手敲了。
先来看看效果:
场景:在费用配置列表中,点击每一项的配置,都会在页面容器内部打开一个新页面,所以新页面的路径一样,根据传的参数不同,面包屑和标签页标题动态改变
二级路由效果(这是用菜单管理新建一条隐藏的路由做法,不推荐)
http://localhost/feeManage/feeConfigDetail?id=4&metaTitle=3253的费用配置
http://localhost/feeManage/feeConfigDetail?id=1&metaTitle=eww的费用配置
三级路由效果(推荐)
路由跳转方法:
// 方法1
this.$router.push({
path: '/feeManage/feeConfig/feeConfigDetail',
query: {
id: row.id,},
})
// 方法2
<router-link :to="'/system/dict-data/index/' + scope.row.dictId" class="link-type">
<span>点击跳转</span>
</router-link>
若依路由简单介绍:
若依vue前端能跳转到新页面路由的方法,我暂且知道这三种形式:
1 在若依的菜单项添加(不推荐)
缺点:因为路由暴露在外面,会发生被误删或者修改错误的情况,造成严重缺陷。
优点:不用写路由配置的代码,可以直接进行路由跳转了。
同时还要注意,这是详细页面,不应该在左侧菜单栏出现,所以要隐藏
2 在router的constantRoutes里添加路由(推荐)
3 在router的dynamicRoutes里添加路由(推荐)
若依字典管理的动态路由配置(如果是想实现像若依字典这样的路由跳转效果,就可以直接参考若依的源码去做:
如果需要权限,需要自己写权限标识(很麻烦,,对接很累)
先是后端写上。。。
然后前端。。。
代码实现
路由配置
实现三级标题的路由怎么写?
{
path: '/feeManage',
component: Layout, // 一级这个component: Layout必填,除非是不需要在页面容器里打开的页面
hidden: true, // false:显示在侧边栏菜单
redirect: 'noRedirect', // noRedirect:面包屑不可点击,不写这个,父级标题样式就和首页一样,黑字可点击跳转
meta: { title: '费用管理'}, // 一级标题,写了才能显示在面包屑上
children: [
{
path: '',
component:{ render: (e) => e("router-view") }, // 如果你的'feeConfig'路径已经在系统菜单中设置过了,这里的path和component就写得和我一样就行,直接跳转三级路由
hidden: true, // false:显示在侧边栏菜单
redirect: 'noRedirect', // noRedirect:面包屑不可点击,不写这个,父级标题样式就和首页一样,黑字可点击跳转
meta: { title: '费用配置'}, // 二级标题,写了才能显示在面包屑上
// 如果你不需要二级的父级标题,那你就直接把第二个children的内容写在第一个children就行
children: [
{
path: 'feeConfig/feeConfigDetail',
component: () => import('@/views/feeManage/feeConfigDetail/index'),
name: 'feeConfigDetail',
meta: { title: '费用配置', activeMenu: '/feeManage/feeConfig' } // meta.title:三级标题,meta.activeMenu:侧边栏父级菜单高亮
}
]
}
]
}
也可以这样写(这样写是建立在之前写的跳转路径不规范,如果不想改代码那么多,只能自己在路由这里改,就不用动业务代码里的跳转路径,当然我强迫症,我最后都改了)
{
path: '',
component: Layout,
hidden: true,
redirect: 'noRedirect',
meta: { title: '运营中心' },
children: [
{
path: '/overseas-collocation',
component:{ render: (e) => e("router-view") }, // 如果你的'merchant'路径已经在系统菜单中设置过了,这里的path和component就写得和我一样就行,直接跳转三级路由
hidden: true, // false:显示在侧边栏菜单
redirect: 'noRedirect', // noRedirect:面包屑不可点击,不写这个,父级标题样式就和首页一样,黑字可点击跳转
meta: { title: '海外拼柜'}, // 二级标题,写了才能显示在面包屑上
// 如果你不需要二级的父级标题,那你就直接把第二个children的内容写在第一个children就行
children: [
{
path: 'detail/:id(\\d+)',
component: () => import('@/views/operation-center/overseas-collocation/collocation-detail'),
name: 'overseasCollocationDetail',
meta: { title: '拼柜详情', activeMenu: '/operation-center/overseas-collocation/overseas-collocation' }
}
]
}
]
}
<router-link :to="'/overseas-collocation/detail/' + scope.row.id">
<el-button type="text">查看</el-button>
</router-link>
改后
面包屑和标签页动态标题配置
配置完路由后,就要讲,如何动态设置路由path不同参数 在页面容器里打开新页面,面包屑和标签页标题根据参数动态改变
使用1方法创建好路由后,然后用$router.push设置传的参数,我们使用metaTitle来当页面标题
this.$router.push({
path: '/feeManage/feeConfigDetail',
query: {
id: row.id,
metaTitle: row.chargeName + '的费用配置'
},
})
如果你只做到了这里,你就会发现,它确实跳转页面了,但是它是同一个页面进行了不同参数的刷新,然后页面的标题也没有动态改变,而是你之前菜单配置时写的标题,如图:
下面就需要改改若依的源码了:
1、先改面包屑
2、在页面容器中,打开新的标签页,改标签页标题(把要修改文件和修改内容框出来,有个明显的对比,知道改哪里)
最后在新页面取出参数
最后效果
有bug
也是写完上面的内容以后,才发现有bug,路径一样,参数不一样的标签,去单击的时候,没有刷新内容,而是保留第一次点击的标签的页面。。。如图
bug解决
原因:若依vue前端源码中用的<router-link>标签进行页面跳转,因为路径一样,参数不一样的页面本质上都是同一个vue,而这个vue已经加载出来就不会进行销毁重新加载了,所以我们要做的就是监听参数然后重新渲染,达到刷新页面的效果
在自己的跳转页面vue中监听路由参数:
二级路由效果
三级路由效果
ps: 找到更好的写法就又补充了一下,所以截图上有些不统一,记得看字看描述哈!
