java spring和ftl

java控制器代码如下

if (questionAnswer.getAnswerId() == 1045) 
  {
    modelAndView.addObject("buttonPressed","You have been added in mailing list");
    modelAndView.setViewName("enterCode_nextSteps");
  } 
else 
  {
    modelAndView.addObject("buttonPressed","Not added in the mailing list");
    modelAndView.setViewName("enterCode_nextSteps");
  }

下面的ajax函数目前运行良好,但我不确定如何在这个ajax函数中访问这个名为“buttonpressed”的对象。我已经像下面提到的那样写了,但是当我点击提交链接时,它没有调用“partner.do”,并且抛出错误说“buttonPressed”是未定义的(但是在下面的脚本中,它工作正常,调用“partner.do”甚至发布数据)

“buttonPressed”或可能是来自spring controller abcd.java文件的问题。

<div class="partnerOptInBox">
  <div id="optInContent">
    <form name="partnerOptIn">
      <h4>Want the Latest</h4>
      <p class="pad10Top">${partnerOpt.translation}</p>
      <div class="pad10Top">
        <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" value="${partnerOpt.getAnswers()[0].answerId}" class="radioButton" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel pad20Right">Yes</label> <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" class="radioButton" value="${partnerOpt.getAnswers()[1].answerId}" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel">No</label>
      </div>
      <div id="optInError" class="formError" style="display:none;">Oops... your request did not go through, please try again.</div>
      <div class="pad15Top">
        <a href="javascript:submitOptIn();"><img src="images/theme/btn_opt_in_submit.gif"/></a>
      </div>                           
    </form>
    <script type="text/javascript">
  function submitOptIn() {
    $('optInError').hide();
    dataString = $('#partnerOptIn').serialize();
    $.ajax({
        data: dataString,
        url: "partnerOpt.do",
        timeout: 30000,
        type: "POST",
       success: function(html){
        var newHtml = "<h4>Thank you</h4><p>We appreciate your time to respond to our request.</p>";
        $('#optInContent').html(newHtml);
},

*/trying this code for sucess is throwing me an error /*
<!-- buttonpressed function-->
    success: function(html){
      $('#optInContent').html(${buttonPressed});
    },

<!-- buttonpressed function-->

error: function(){
      $('#optInError').show();
      }
  });
}
</script>
