Location API

The Location API contains functionality for working with a page's URL and for navigating visitors to other pages. 

Let's take a look at some of the functionality that's available in the Location API.

Query Parameters

There are many situations where you might want to read query parameters from a page's URL or to edit the query parameters in the URL. 

For example, you might want to send information between pages using query parameters. Or you might want to update the query parameters on a page that displays dynamic content to reflect the current content shown on the page.

Reading Query Parameters

To read query parameters from a URL, use the query property. The query property returns an object where the keys of the object are the keys in the URL's query string and the values in the object are the corresponding values in the query string.

For example, let's say you have a URL like this:
Copy Code

You can retrieve the query parameters like this:

const query = wixLocation.query;
javascript | Copy Code

The query variable will then contain the following object:

{ key1: "value1", key2: "value2" }
javascript | Copy Code

Editing Query Parameters

To edit the query parameters of a URL, use the queryParams property. The queryParams property returns an object with functions for adding and removing query parameters.

The add() function adds new key:value pairs to the query string or replaces existing ones. You call the function by passing an object that contains the key:value pairs you want to add or update.

So, if you start with a URL like this:
Copy Code

Then, you call the add() function like this:

wixLocation.queryParams.add({ key2: "new2", key3: "value3" });
javascript | Copy Code

The URL will look this this:
Copy Code

As you can see, the following occurs:

  • The value for key1 remains the same since it was not included in the object passed to the add() function.
  • The value for the original key2 is replaced by the new value passed to the add() function.
  • The key key3 and its value are added because key3 did not exist in the original URL.

The remove() function removes existing key:value pairs from the query string. You call the function by passing an array of the keys you want to remove.

So, if you start with a URL like this:
Copy Code

Then call the remove() function like this:

wixLocation.queryParams.remove(["key1", "key3"]);
javascript | Copy Code

The URL will look this this:
Copy Code


Often times you'll want to write code that sends visitors to another page in your site or to an external address. There are a couple of ways to accomplish this.

If you want to send a site visitor to another page in response to a click on an element that has a link property, you can use that property to define where the visitor will be sent.

For example, this code sets the link for a button, depending on whether the current user is logged in:

import {currentUser} from 'wix-users';
$w.onReady(function () {
$w('#button').link = currentUser.loggedIn ? '/account/my-account' : '/signup';
javascript | Copy Code

When a visitor clicks on the button, the browser will navigate to the appropriate page.

However, there are some situations where you can't use an element's link property to send a visitor to another page, such as when:

  • The element you want to use to trigger the navigation does not have a link property, like a Box or a Container.
  • You want to navigate a visitor to another page in response to an action that is not a click.
  • You want to run some other code in response to a visitor action and then navigate the visitor when that code has finished running.

In these cases, you need to use the to() function. To use the to() function, simply pass it the URL you want to navigate to. You can use relative URLs if you're navigating to a page in the current site.

For example, to implement a submit button for a form, you might want to submit the form data to a database collection and then navigate the visitor to a thank you page. Your code might look something like this:

$w('#submitButton').onClick( async () => {
await submitFormData();'/thank-you');
} );
javascript | Copy Code

Here you can see that the onClick event handler first calls a function to submit the form data to a database collection. When the submission is complete, the visitor is sent to a thank you page.

We've now seen a couple of ways to handle element clicks with code. These are in addition to the ways clicks might be handled using the Editor that we haven't discussed.

That leaves you with lots of options when it comes to clickable elements:

  • Set the link property in code.
  • Set an onClick event handler in code.
  • Set the link behavior using the Editor's link panel.
  • Connect the Click action or Link connection to a dataset.

Because there are multiple options, and some of them might conflict with each other, it is important to choose only one option per element. If you use more than one option on the same element, the results may be unpredictable.
