我正在使用工具提示验证表单并使用警告消息对后端响应执行ajax调用。虽然我正在验证我正在使用表单ID进行ajax调用和工具提示验证。所以我的问题是，即使我得到空文本验证并进入ajax成功调用。如何将工具提示与ajax调用结合起来。
script.
$(document).ready
console.log('bbbbbbbb');
$('#loginform').submit(function(e) {
console.log('submit called');
var data = {};
data.email = $('#username').val();
data.password = $('#password').val();
JSON.stringify(data);
console.log(data);
$.ajax({
url: "/login",
type: "POST",
dataType: 'json',
data: JSON.stringify({ "objectData": data}),
contentType: "application/json",
success: function(data) {
alert('SUCCESS":'+JSON.stringify(data));
var successVar = data;
alert(successVar.data);
if(successVar.data == "Invalid username And Password"){
showfailure();
}
if(successVar.data == "Login successfully"){
showdiv();
location.href='http://localhost:3000/landing';
}
},
});
return false;
});
$('#loginform').click(function(){
loginValidation();
});
function loginValidation(){
$('#loginform').validate({
rules : {
email_id : {
minlength : 5,
required : true,
email : true
},
password : {
minlength : 5,
required : true
}
},
messages : {
email : "Enter Valid Email Address.",
password : "Enter Password"
}
});
}
