Hi,
We can pass the data to a custom controller using ajax.rpc method.
var a = "Hello"
ajax.rpc('/webform',{a}) here {a} contain data that accessible from controller in dictionary form
@http.route(['/webform'], type='json', auth="public")
def function_name(self,**kwargs ):
print(kwargs) While printing the */kwargs/* in the function of our controller we will get */Hello/* as the result.
Regards
