我已经使用jquery ajax发送了api请求，而我正在收到这样的ajax响应
Array（[consumer_key] => ada691a715307861907d65d36d [consumer_secret] => a75e40ec1530786190b62316d1 [consumer_nonce] => 1537011049789 [consumer_device_id] => ldx0EWMCl3hNhJWCRIdPVveLy [] ]，“ message”：“电子邮件地址已经存在”}
如果响应中包含“电子邮件地址已存在”，我想显示错误消息，否则警报消息“已成功提交”
$.validator.setDefaults({
submitHandler: function() {
alert("submitted!");
var customers_firstname=$("#customers_firstname").val();
var customers_lastname=$("#customers_lastname").val();
var customers_telephone=$("#customers_telephone").val();
var email=$("#email").val();
var d = new Date();
var consumer_nonce = d.getTime();
U=url+'api/save_reg';
//alert(consumer_nonce);
//exit;
//var ul="{{ url('/backend/api/save_reg') }}";
$.ajax({
type:"POST",
url:url+'api/save_reg',
data:$("#postcontent").serialize(),
/* data:{

//-- alert(response[1]);

$("#return_update_msg").html(response);
$(".post_submitting").fadeOut(1000);
