For my Asp.Net MVC signup project, I'm trying to add Captcha for human validation.
Here I have downloaded the NuGet package called CaptchaMVC5.
In the view In the manual, it asked to add it as,
@using CaptchaMvc.HtmlHelpers;
<div class="form-custom form-label form-icon mb-3" id="captchaText">
@Html.Captcha(5)
<p class="text-danger"> @ViewBag.ErrorMessage</p>
</div>
So I created a ajax call to check the captcha is valid or invalid
$.ajax({
type: "POST",
url: '/Account/CaptchaCheck',
data: {},
success: function (data) {
if (data.Success == true) {
} else {
toastr.error(data.errorMsg);
}
},
error: function () {
alert("Pleas try again");
}
})
This is the Controller code I wrote
public JsonResult CaptchaCheck() {
if (!this.IsCaptchaValid("")) {
return Json(new {
Success = true,
errorMsg = "Captcha Is Invalid"
}, JsonRequestBehavior.AllowGet);
} else {
return Json(new {
Success = false,
}, JsonRequestBehavior.AllowGet);
}
}
I want to know is there any way of sending the captcha from the ajax call to the controller and check the captcha is valid or invalid.
