jquery验证插件在远程运行时停止

很遗憾，我的一个项目有一个小问题

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

我在此表单上使用jquery验证插件：

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

}))； });

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

还有checkemail.php（checkusername.php与之相同，但显然是用户名而不是电子邮件）：

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

包括（'dbcon.php'）； 如果（isset（$_POST['email']））

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

}

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

我已经尝试了我找到的每一种组合。简单的遥控器：“url”，带有类型和数据：{function….}等的遥控器。没有任何东西可以工作。。。对于check PHP文件也是如此，每当我在验证代码中放入远程行时，当我单击submit时，表单就会停止工作。如果我拆下遥控线路，一切都能正常工作。有人知道问题出在哪里吗？我真的没有主意了，也找不到地方找了。

所以

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

我将我的php文件更改为此，因为我认为这就是我的整个验证停止的地方：

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

如果（isset（$_POST['email']））

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

但还是没什么。。。我没有收到任何消息，我的表单不会提交，除非我删除“远程：”url“部分。。然后一切又恢复正常了…

我让那部分工作起来了，问题是相对url的，它找不到php文件，所以我现在使用../I代替../I，它一直工作到那里，但在控制台中它给了我200 ok，它给了我“true”无论电子邮件和用户是否可用，它都不会在表单中给我任何消息。。。有人知道如何解决这个问题吗

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

另外，如果我将数据：{x:function..}放入并键入，它将跳过整个验证过程，让我提交一个空表单

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>
