我试图将我的数据从 ajax 传递到 php，然后传递到数据库，但我发现错误提示未捕获的错误 - "undefined function is_ajax"
…………我的 js 代码…………
var form = document.getElementById('form');
form.addEventListener("submit",validateForm)
function validateForm(e) {
e.preventDefault();
var name = document.forms["form"]["name"] .value;
var ml = document.forms["form"]["mail"] .value;
var num = document.forms["form"]["number"] .value;
var ctry = document.forms["form"]["country"] .value;
var date_in = document.forms["form"]["date_in"] .value;
var time_in = document.forms["form"]["time_in"] .value;
var time_out = document.forms["form"]["time_out"] .value;
$.ajax({
type: "POST",
url: "data.php",
data:{myname:name,myemail:ml,c_num:num,c_ctry:ctry,in_date:date_in,in_time:time_in,out_time:time_out},
success:function(reply){
var respOutPut = String(reply);
console.log("OutPut:" + respOutPut);
if (respOutPut.trim() == "not Ajax Request"){
}
},
error: function () {
console.log("Error:");
}
});
}

您可以像这样发送表单数据
var formData = $(form).serializeArray();
$.ajax({
type: "POST",
url: "data.php",
data:{formData},
success:function(reply){
var respOutPut = String(reply);
console.log("OutPut:" + respOutPut);
if (respOutPut.trim() == "not Ajax Request"){
}
},
error: function () {
console.log("Error:");
}
});
在您的 php 中，您可以通过 $_POST 获取它们。
