tip: 用params传参,F5强制刷新参数会被清空,用query,由于参数适用路径传参的所以F5强制刷新也不会被清空。(传参强烈建议适用string)
也可以选用sessionstorage/localstorage/cookie存储
1.params:参数不会显示到路径上
配置路径rutes
export default new Router({
routes: [
{
path: '/path1',
name: 'path1',//一定要写name,params必须用name来识别路径
component: Path1
}
]
})
2.传递参数:用$router
<!-- test-vue-router页面 -->
<template>
<div>
<a @click="routerTo()">query传参</a>
</div>
</template>
<script>
export default {
methods: {
routerTo() {
this.$router.push({
name: `TestVueRouterTo`,
params: {
page: '1', code: '8989'
}
})
}
}
}
</script>
3.接受参数: 用$route
<!-- test-vue-router-to页面 -->
<template>
<div>
</div>
</template>
<script>
export default{
data() {
return {
page: '',
code: ''
}
},
created() {
this.getRouterData()
},
methods: {
getRouterData() {
this.page = this.$route.params.page
this.code = this.$route.params.code
console.log('page', this.page)
console.log('code', this.code)
}
}
}
</script>
query: 最好也用name来识别,保持与params一致性,路径传参
1.路径配置(跟params一样)
2.参数传递页
<!-- test-vue-router页面 -->
<template>
<div>
<a @click="routerTo()">query传参</a>
</div>
</template>
<script>
export default {
methods: {
routerTo() {
this.$router.push({
name: `TestVueRouterTo`,
// 只是把query改了,其他都没变
query: {
page: '1', code: '8989'
}
})
}
}
}
</script>
3.接受参数
<!-- test-vue-router-to页面 -->
<template>
<div>
</div>
</template>
<script>
export default{
data() {
return {
page: '',
code: ''
}
},
created() {
this.getRouterData()
},
methods: {
getRouterData() {
// 只是改了query,其他都不变
this.page = this.$route.query.page
this.code = this.$route.query.code
console.log('page', this.page)
console.log('code', this.code)
}
}
}
</script>
