Try this code:
import wixData from "wix-data"
import wixLocation from "wix-location"
$w.onReady(() => {
$w("#gg").onClick(() => {
let username = $w("#name").value
let password = $w("#lname").value
wixData
.query("Profile")
.eq("firstName", username)
.eq("lastName", password)
//make sure the field names that you search in the query
//are the same as the actual fields in the data base.
.find()
.then(results => {
if (results.length > 0) {
wixLocation.to(`/profile/` + firstName)
// using the wix location API,
// make sure you return the full destination URL
}
})
.catch(err => {
console.log("err", err)
})
})
})
Remember to delete any event handler attached to the gg button.
