I have this Asp Net Core Web Api application as my backend with all the Apis that I need using default route system localhost\api\controller\id .
(我使用默认的路由系统localhost\api\controller\id将这个Asp Net Core Web Api应用程序作为我的所有Apis的后端。)
All Apis are working fine when calling from PostMan, but when I try to use Jquery Ajax to call them in my FrontEnd, things don't run properly.(从PostMan进行调用时，所有Apis都可以正常工作，但是当我尝试使用Jquery Ajax在FrontEnd中调用它们时，事情就无法正常运行。)
Sorry if this question looks stupid, I'm new to JavaScript so ill really appreciate your guys help!(抱歉，如果这个问题看起来很愚蠢，我是JavaScript的新手，所以非常感谢您的帮助！)
I only have got the 'Get' method to list in a table modifying the HTML with the result:
(我只有'Get'方法在用结果修改HTML的表中列出：)
$(document).ready(function () {
$('#btn-lista-alunos').click(function () {
$.ajax({
url,
type: 'GET',
dataType: 'json', // Returns JSON
success: function (response) {
$('#tabela-alunos td').remove("");
$('#info p').remove();
var sTxt = '';
$.each(response, function (index, val) {
sTxt += '<tr>';
sTxt += '<td>' + val.id + '</td>';
sTxt += '<td>' + val.nome + '</td>';
sTxt += '<td>' + val.ra + '</td>';
sTxt += '<td>' + val.curso + '</td>';
sTxt += '<td>' + val.periodo + '</td>';
sTxt += '<td>' + val.nota + '</td>';
sTxt += '<td>' + ValidaStatus(val.nota) + '</td>';
sTxt += '</tr>';
});
$('#tabela-alunos').append(sTxt);
},
error: function () {
$('#info').html('<p>Ocorreu um erro, verifique a conex?o com a api!</p>');
}
});
});
//Botao Limpar Lista
$('#btnClear').click(function () {
$('#tabela-alunos td').remove();
$('#info p').remove();
});
});

How can I use Ajax to send the form as a JSON to my BackEnd and Edit/Delete an Object Value Listed on my first page?
(如何使用Ajax将表单作为JSON发送到我的后端并编辑/删除第一页上列出的对象值？)
I already have tried quite a few things but none of that worked.(我已经尝试了很多东西，但是都没有用。)
Thanks!(谢谢！)
