How can I fetch query parameters in Vue.js?
E.g. http://somesite.com?test=yay
.
Can’t find a way to fetch or do I need to use pure JS or some library for this?

According to the docs of route object, you have access to a $route
object from your components, which exposes what you need. In this case
//from your component
console.log(this.$route.query.test) // outputs 'yay'
Without vue-route, split the URL
var vm = new Vue({
....
created()
{
let uri = window.location.href.split('?');
if (uri.length == 2)
{
let vars = uri[1].split('&');
let getVars = {};
let tmp = '';
vars.forEach(function(v){
tmp = v.split('=');
if(tmp.length == 2)
getVars[tmp[0]] = tmp[1];
});
console.log(getVars);
// do
}
},
updated(){
},
Another solution https://developer.mozilla.org/en-US/docs/Web/API/HTMLHyperlinkElementUtils/search:
var vm = new Vue({
....
created()
{
let uri = window.location.search.substring(1);
let params = new URLSearchParams(uri);
console.log(params.get("var_name"));
},
updated(){
},
More detailed answer to help the newbies of VueJS:
And the code itself:
<script src="https://unpkg.com/vue-router"></script>
var router = new VueRouter({
mode: 'history',
routes: []
});
var vm = new Vue({
router,
el: '#app',
mounted: function() {
q = this.$route.query.q
console.log(q)
},
});
Another way (assuming you are using vue-router
), is to map the query param to a prop in your router. Then you can treat it like any other prop in your component code. For example, add this route;
{
path: '/mypage',
name: 'mypage',
component: MyPage,
props: (route) => ({ foo: route.query.foo })
}
Then in your component you can add the prop as normal;
props: {
foo: {
type: String,
default: null
}
},
Then it will be available as this.foo
and you can do anything you want with it (like set a watcher, etc.)
As of this date, the correct way according to the dynamic routing docs is:
this.$route.params.yourProperty
instead of
this.$route.query.yourProperty
You can use vue-router.I have an example below:
url: www.example.com?name=john&lastName=doe
new Vue({
el: "#app",
data: {
name: '',
lastName: ''
},
beforeRouteEnter(to, from, next) {
if(Object.keys(to.query).length !== 0) { //if the url has query (?query)
next(vm => {
vm.name = to.query.name
vm.lastName = to.query.lastName
})
}
next()
}
})
Note: In beforeRouteEnter
function we cannot access the component's properties like: this.propertyName
.That's why i have pass the vm
to next
function.It is the recommented way to access the vue instance.Actually the vm
it stands for vue instance
(as far as now 2021, vue-router 4)
import {useRouter} from "vue-router";
//can use only in setup()
useRoute().query.test
or
//somewhere in your src files
import router from "~/router";
//can use everywhere
router.currentRoute.value.query.test
or
import {useRouter} from "vue-router";
//can use only in setup()
useRouter().currentRoute.value.query.test
