Javascript 在php中调用表单提交的jquery函数

我使用此代码请求新用户在首次登录时更改其密码。这是我的表单，第一次登录后会弹出：

<div class="modal" id="change-password-modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-backdrop="static" data-keyboard="false">
          <div class="modal-dialog modal-lg" role="document" style="top:20%">
            <div class="modal-content content-align">
              <div class="modal-header">
                <h3 class="modal-title text-center modal-title-col">Change your password</h3>
              </div>
              <div class="modal-body">
                <form id="change-password" class="ns-form half-width" method="post" action="/profile/changepassword">
                  <?php if(empty($_POST) || isset($exc)): ?>
                  <label>
                    <input class="input-box" type="password" name="curr_pwd" required="required" maxlength="64" placeholder="Current Password" required="required" />
                    <?php if(isset($exc) && $exc->getCode() == eInfo::INVALID_CREDENTIALS): ?>
                      <span class="error msg-block bottom">
                        <?php echo stripslashes($exc->getMessage()); ?>
                      </span>
                    <?php endif; ?>
                  </label>
                  <label>
                    <input class="input-box" type="password" name="new_pwd" required="required" maxlength="64" placeholder="New Password" />
                      <?php if(isset($exc) && $exc->getCode() == eInfo::INVALID_PASSWORD): ?>
                        <span class="error msg-block bottom">

                      <?php endif; ?>
                  </label>
                  <label>
                    <input class="input-box" type="password" name="retype_pwd"
                           required="required" maxlength="64" placeholder="Re-type Password" />
                  </label>
                  <center> <input type="submit" value="Change" class="change-button" id="change-button" /> </center>
                  <?php endif; ?>
                </form>
                <?php if(!empty($_POST) && !isset($exc) && isset($message)): ?>
                    <br/>
                    <strong><?php echo $message; ?></strong>
                    <br/>
                    <center><a href="/">Go home</a></center>
                <?php endif; ?>
              </div>
              </div>
            </div>
          </div>
        </div>

这是一个基本的小问题，但我不知道怎么做。谢谢

或者将changepassword中的代码移动到表单所在的页面，这样您就可以将表单发送到它自己的页面，因此不需要重定向，或者您必须使用。

如果要避免重定向，请使用AJAX如果要避免重定向，请使用AJAX
