Question

我制作了一个Web表单以向数据库添加一些字符串，现在我的add函数运行正常，但是当我单击Submit并将控制台日志发送undefined给我时，我的Web并没有发送参数来运行我不知道什么做的请帮忙，谢谢你

这里是我的功能代码，可以完美运行

Parse.Cloud.define('addSynonym', function (request, response) {
  var SYN = Parse.Object.extend("Synonym");
  var CommonwordFromUser = request.params.common_word;
  var SynonymwordFromUser = request.params.synonym_word;
  console.log(CommonwordFromUser);
  console.log(SynonymwordFromUser);
  if (CommonwordFromUser == null || SynonymwordFromUser == null) {
    response.error("request null values");
  } else {
    var query = new Parse.Query(SYN)
    query.find({
      success: function (synResponse) {
        var synOBJ = new SYN();
        synOBJ.set("common_word", CommonwordFromUser);
        synOBJ.set("synonym_word", SynonymwordFromUser);
        synOBJ.save(null, {
          success: function (success) {
            response.success({
              "common_word": CommonwordFromUser,
              "synonym_word": SynonymwordFromUser
            });
          },
          error: function (error) {
            response.error("save failed : " + error.code);
          }
        });
      }
    })
  }
});

这是我的问题所在的网页

    <form id="contact" class="registerForm">

      <div class="alert alert-success" id="alertbox">
        <strong>Success!</strong> Your Synonym has uploaded.
      </div>

      <div class="text-center">
        <img src="img/icon.png" class="text-center" alt="Responsive image" width="90" height="90">
      </div>
      <h3 class="text-center font-weight-normal">Welcome to synonym Menu</h3>

      <label id="label-tags" for="ask-tags">Common Word :</label>
      <fieldset class="form-group">
        <input id="common_word" name="common_word" placeholder="Please type some word" type="text" tabindex="1" required>
      </fieldset>
      <label id="label-tags" for="ask-tags">Synonym Word :</label>
      <fieldset class="form-group">
        <input id="synonym_word" name="synonym_word" placeholder="Please type some word" type="text" tabindex="2"
          required>
      </fieldset>
      <fieldset class="form-group">
        <button name="submit" type="submit" onclick="submitfrom()" id="contact-submit">Submit</button>
      </fieldset>
      </form>
  </div>

Answer 1

选项1：只需更改下面的行，它应该可以工作

var obj = {
  "common_word": common_word,
  "synonym_word": synonym_word,
};

var data = JSON.stringify(obj);

选项2（推荐）：

安装Parse JS SDK：https://docs.parseplatform.org/js/guide/#getting-started
像这样调用云代码：

Parse.Cloud.run(
  "addSynonym",
  {
    "common_word": common_word,
    "synonym_word": synonym_word
  }
).then(
  function() {
    console.log('success');
  },
  function (error) {
    console.error(error);
  }
);

如何从网页发送参数来解析云功能？
