The Ajax URL is the URL that the Ajax request is sent to. You can specify the URL by setting the `url` property in the Ajax settings object. Here's an example:
$.ajax({
url: "https://example.com/api/data",
type: "GET",
success: function(response) {
// Handle the response
},
error: function(xhr, status, error) {
// Handle the error
}});
In this example, the `url` property is set to `https://example.com/api/data`. When the Ajax request is made, it will be sent to this URL.
Note that the URL can be a relative or absolute URL, and can include query parameters and a fragment identifier. The `type` property specifies the HTTP method to use for the request (e.g., `GET`, `POST`, etc.), and the `success` and `error` properties specify functions to handle the response and error, respectively.
It's important to ensure that the URL is valid and points to the correct endpoint on the server. If the URL is incorrect or malformed, the Ajax request will fail.
