Delete the query parameter from the router

Question

Delete the query parameter from the router

In my Vue project, I am using the replace method to add a query to the current URL. If the value is not present, I'm assigning undefined.

this.$router.replace({
  name: "admin-frs",
  query: {
    limit: this.pageSize,
    page: this.currentPage,
    sort: this.sortbyapi || undefined,
    language: this.sortbyapiLang || undefined,
  },
})

This approach causes the query item to disappear from the URL when the query data is updated, but it does not remove it from the query object itself.

I'm wondering if there may be a better way to handle this situation. Additionally, I'm curious if it's possible to retrieve the query as it appears in the route, like &limit=10...etc.

Answer №1

It seems the OP is looking to modify the query object passed to router.replace. This can be achieved using standard JavaScript.

Begin by giving a specific name to the query variable...

let query = $router.query;

To delete something, utilize the JS delete operator. For instance, to eliminate query.limit...

// remove the limit
if (!this.pageSize) delete query.limit;

Alternatively, if you are constructing that query, refrain from including limit initially...

let query = {};
if (this.pageSize) query.limit = this.pageSize;
if (this.currentPage) query.page = this.currentPage;
// and so on for other properties
// the query now only contains specified props above

Perform any of these modifications, then pass them to the router using the variable reference...

$router.replace({ name: "admin-frs", query });

To convert it into a string, there are multiple approaches available, including various methods within libraries you may have, but in vanilla code...

let params = [];
for (let key in query)
  params.push(`${encodeURIComponent(key)}=${encodeURIComponent(query[key])}`);
const queryString = params.join("&");
