为什么我点击注册按钮时没有收到警报消息？

Question

When i click the Sign up button, I dont get the alert message. Other alerts show the output perfectly. But I think there is problem in the else statement. I want to show the alert message when any user click the Sign up button.

function check(form) {
    name = form.name.value;
    mobile = form.mobile.value;
    age = form.age.value;
    email = form.email.value;
    password = form.password.value;
    conpassword = form.conpassword.value;

    if(name==''){
        swal({
              title: "Empty Field!",
              text: "Enter Name",
              icon: "warning",
            });
        return false;
    }

    else if(mobile==''){
        swal({
              title: "Empty Field!",
              text: "Enter Mobile Number",
              icon: "warning",
            });
        return false;
    }

    else if(age==''){
        swal({
              title: "Empty Field!",
              text: "Enter Age",
              icon: "warning",
            });
        return false;
    }

    else if(email==''){
        swal({
              title: "Empty Field!",
              text: "Enter E-mail",
              icon: "warning",
            });
        return false;
    }

    else if(password==''){
        swal({
              title: "Empty Field!",
              text: "Enter Password",
              icon: "warning",
            });
        return false;
    }

    else if(conpassword==''){
        swal({
              title: "Empty Field!",
              text: "Enter Confirm Password",
              icon: "warning",
            });
        return false;
    }

    else if(password!=conpassword){
        swal({
              title: "",ant
              text: "Password Did Not Match",
              icon: "error",
            });
        return false;
    }

    else{
        swal({
              title: "Thank You!",
              text: "Now you can access",
              icon: "success",
            });
       return true; 
    }
}

I use SweetAlert ( swal() )

in your html one is wrong and in
javascript ,ant after title is cause error

else if(password!=conpassword){
    swal({
          title: "",ant/*wrong*/
          text: "Password Did Not Match",
          icon: "error",
        });
    return false;
}

 function check(form) { name = form.name.value; mobile = form.mobile.value; age = form.age.value; email = form.email.value; password = form.password.value; conpassword = form.conpassword.value; if(name==''){ swal({ title: "Empty Field!", text: "Enter Name", icon: "warning", }); return false; } else if(mobile==''){ swal({ title: "Empty Field!", text: "Enter Mobile Number", icon: "warning", }); return false; } else if(age==''){ swal({ title: "Empty Field!", text: "Enter Age", icon: "warning", }); return false; } else if(email==''){ swal({ title: "Empty Field!", text: "Enter E-mail", icon: "warning", }); return false; } else if(password==''){ swal({ title: "Empty Field!", text: "Enter Password", icon: "warning", }); return false; } else if(conpassword==''){ swal({ title: "Empty Field!", text: "Enter Confirm Password", icon: "warning", }); return false; } else if(password!=conpassword){ swal({ title: "Empty Field", text: "Password Did Not Match", icon: "error", }); return false; } else{ swal({ title: "Thank You!", text: "Now you can access", icon: "success", }); return true; } }
