配置动态路由参数id：
routes: [
// 动态路径参数 以冒号开头
{ path: '/user/:id', component: User }
]
html路由跳转：
<router-link to="/demo53/8">路径参数跳转</router-link>
①不带参数写法：
<router-link to="home">点我</router-link>
<router-link v-bind:to="'home'">点我</router-link>
<router-link :to="'home'">Home</router-link>
<router-link :to="{ path: 'home' }">Home</router-link>
② 带参数写法：
A： <router-link :to="{ name: 'user', params: { userId: 123 }}">User</router-link>
批注：路由配置格式：
{ path: '/user/:userId', name: 'user', component: User }
导航显示：/user/123
B: <router-link :to="{ path: 'register', query: { plan: 'private' }}">Register</router-link>
批注：带查询参数
导航显示：/register?plan=private
js中使用的方式：
① this.$router.push('xxx') //字符串,这里的字符串是路径path匹配噢，不是router配置里的name
② this.$router.push({ path: 'home' }) //对象
③ this.$router.push({ name: 'user', params: { userId: 123 }}) // 命名的路由 这里会变成 /user/123
④ this.$router.push({ path: 'register', query: { plan: 'private' }}) // 带查询参数，变成 /register?plan=private
vue之this.$route.query和this.$route.params接收参数 this.$route.query A页面传递参数peng=0 registerInfoThis.$router.push("/hrhi/psninfo/dynamic/" + data.row.pk_psndoc + '?funcode=60070psninfo&peng=0'); B页面接收参数 created() { this.penga = this.$route.query["peng"]; },
‘http://localhost:8080/linkParamsQuestion?age=18’
let age = this.$route.query.age; //问号后面参数会被封装进 this.$route.query;
this.$route.params 1、router/index.js { path:'/mtindex', component: mtindex, //添加路由 children:[ { path:"/detail", name:'detail', component:guessdetail } ] }, 2、传参数（ params相对应的是name query相对应的是path） this.$router.push({ name: ‘detail’, params:{shopid: item.id} }); 3、获取参数 this.$route.params.shopid 4、url的表现形式(url中没带参数) http://localhost:8080/#/mtindex
3.检测路由 watch:{ '$route': function (to,from) { // 对路由变化作出响应... } } 或者 watch: { "$route": "routeChange", }, methods: { routeChange(){ console.log(this.$route.path); } }
在 router-view上加上一个唯一的key，来保证路由切换时都会重新渲染触发钩子了
<router-view :key="key"></router-view> computed: { key() { return this.$route.name !== undefined? this.$route.name + +new Date(): this.$route + +new Date() } }
HttpGet请求拼接url参数
const query = { client_id: state.auth.clientID, redirect_uri: location.href, scope: 'public_repo' } const queryString = Object.keys(query) .map(key => `${key}=${encodeURIComponent(query[key] || '')}`) .join('&') return `http://github.com/login/oauth/authorize?${queryString}`
return vue.$http.get(`https://api.github.com/search/issues?q=${data.keyword}+state:open+repo:${vue.$store.getters.repo}${label}&sort=created&order=desc&page=${data.currentPage}&per_page=${data.pageSize}`, { headers: { 'Accept': 'application/vnd.github.v3.html' } })
url参数转json字符串：
const queryParse = (search = window.location.search) => { if (!search) { return {} } else { const queryString = search[0] === '?' ? search.substring(1) : search const query = {} queryString .split('&') .forEach(queryStr => { const [key, value] = queryStr.split('=') if (key) { query[decodeURIComponent(key)] = decodeURIComponent(value) } }) return query } } const queryStringify = query => { const queryString = Object.keys(query) .map(key => `${key}=${encodeURIComponent(query[key] || '')}`) .join('&') return queryString }
获取url参数
//方法封装
function GetRequest() {
//获取url中"?"符后的字串
var url = location.search;
var theRequest = new Object();
if (url.indexOf("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
theRequest[strs[i].split("=")[0]]=decodeURI(strs[i].split("=")[1]);
}
}
return theRequest;
}
// 方法调用
var Request = new Object();
Request = GetRequest();
var urlCan = Request['参数名'];
function getUrlParam(key) {
// 获取参数
var url = window.location.search;
// 正则筛选地址栏
var reg = new RegExp("(^|&)" + key + "=([^&]*)(&|$)");
// 匹配目标参数
var result = url.substr(1).match(reg);
//返回参数值
return result ? decodeURIComponent(result[2]) : null;
}
//调用
getUrlParam("参数名");
