My ajax request return status error 405 on laravel - ajax

Question

I'm using laravel 6. IT returns me error 405 when using external ajax.js file to handle my form.
message: The POST method is not supported for this route. Supported methods: GET, HEAD.
This is my form in blade:
<form >
#csrf
<div class="form-group">
<label>Name:</label>
<input type="text" name="name" class="form-control" placeholder="Name" required="">
</div>
<div class="form-group">
<label>Password:</label>
<input type="password" name="password" class="form-control" placeholder="Password" required="">
</div>
<div class="form-group">
<strong>Email:</strong>
<input type="email" name="email" class="form-control" placeholder="Email" required="">
</div>
<div class="form-group">
<button class="btn btn-success btn-submit">Submit</button>
</div>
</form>
my ajax.js:
$(document).on('submit','#employeeSignupFrom',function (e) {
var token = $('input[name="_token"]').attr('value')
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': token
}
});
$.ajax({
$url:'/signupemployee',
type:'post',
data: $(this).serialize(),
contentType:'json',
success: function( response, textStatus, jQxhr ){
alert('done')
},
error: function( jqXhr, textStatus, errorThrown ){
alert('error!');
}
});
e.preventDefault()
})
the route(web.php):
Route::post('/signupemployee','FormsController#signupEmployee');
and my controller:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
class FormsControllers extends Controller
{
public function signupEmployee(Request $request){
$employeeInfo=$request->all();
return response()->json(['alert'=>'done!']);
}
}

First remove $ sign from your url:
//$url:'/signupemployee', <- remove $
url:'/signupemployee',
Second change contentType to:
contentType: 'application/json',
Finally your ajax should be something like this:
$.ajax({
url: '/signupemployee', //<- $ sign should deleted
type: 'POST',
data: data,
contentType: 'application/json', //<- not just json
headers: {
'X-CSRF-TOKEN': token
}
})
