将输入保存到Parse（Javascript）

时间：2014-12-30 13:28:24

标签： javascript jquery parse-platform

目前，当用户选择文件时，它会直接上传到Parse。我现在已经添加了几个输入文本字段，例如个人姓名，我想要同时记录到Parse中的地址，只有当用户点击了当前用户选择文件后自动提交的选择按钮时

＆＃13;
＆＃13; 
$(document).ready(function() {
  // ***************************************************
  // NOTE: Replace the following your own keys
  // ***************************************************
  Parse.initialize("id", "id");

  function saveDocumentUpload(objParseFile) {
    var documentUpload = new Parse.Object("Scan");
    documentUpload.set("Name", "");

    documentUpload.set("DocumentName", objParseFile);
    documentUpload.save(null, {
      success: function(uploadResult) {
        // Execute any logic that should take place after the object is saved.
        var photo = uploadResult.get("profileImg");
        $("#profileImg")[0].src = photo.url();
      },
      error: function(uploadResult, error) {
        // Execute any logic that should take place if the save fails.
        // error is a Parse.Error with an error code and description.
        alert('Failed to create new object, with error code: ' + error.description);
      }
    });

   
  }

  $('#documentFileUpload').bind("change", function(e) {
    var fileUploadControl = $("#documentFileUpload")[0];
    var file = fileUploadControl.files[0];
    var name = file.name; //This does *NOT* need to be a unique name
    var parseFile = new Parse.File(name, file);

    parseFile.save().then(
      function() {
        saveDocumentUpload(parseFile);
      },
      function(error) {
        alert("error");
      }
    );
  });
});

你有两次“documentFileUpload”：

更改： 

<form>
    <input type="file" id="documentFileUpload">
    <br />
    <input type="text" value ="UserID"><br />
    <input type="text" value ="Address"> <br />
    <input type="submit"  id="documentFileUpload" value="submit">

</form>

要 

<form>
    <input type="file" id="documentFileUpload">
    <br />
    <input type="text" value ="UserID"><br />
    <input type="text" value ="Address"> <br />
    <input type="submit"  id="documentFileUploadButton" value="submit">

</form>

修改

要回答有关记录UserId和地址字段的评论，请参阅以下代码。我将文件上传绑定更改为按钮并绑定了click事件。这将修复您在选择时上传的文件。

另外，添加了id的user_id和地址，以允许jQuery从这些字段中获取值：

$('#documentFileUploadButton').bind("click", function (e) {
        var fileUploadControl = $("#documentFileUpload")[0];
        var file = fileUploadControl.files[0];
        var name = file.name; //This does *NOT* need to be a unique name
        var parseFile = new Parse.File(name, file);

        var user_id = $('#user_id').val();

        var address = $('#address').val();

        parseFile.set('UserId', user_id);
        parseFile.set('Address', address);

        parseFile.save().then(
                function () {
                    saveDocumentUpload(parseFile);
                },
                function (error) {
                    alert("error");
                }
        );
    });

然后：

<form>
    <input type="file" id="documentFileUpload">
    <br/>
    <input type="text" value="UserID" id="user_id">
    <br/>
    <input type="text" value="Address" id="address">
    <br/>
    <input type="submit" id="documentFileUploadButton" value="submit">
</form>

问题是您的提交按钮，文件输入具有相同的ID。相应地更改ID并分别为它们分配事件。将提交事件分配给提交按钮，最终调用上传功能。

答案 2 :(得分：0)

除了发现和修复的其他问题之外，您还尝试将Parse.File视为Parse.Object。

您无法在Parse.File上调用set(column, value)，因为它只是一个文件。保存文件后，将其作为列添加到对象中。

在您的情况下，这意味着UserID和Address列必须放在您的Scan课程上。另外，我建议您将UserID列更改为指针并将其命名为User，因为它会使查询更容易，例如：

  function saveDocumentUpload(objParseFile)
  {
     var documentUpload = new Parse.Object("Scan");
     documentUpload.set("Name", "");

     documentUpload.set("DocumentName", objParseFile);

     var user_id = $('#user_id').val();

     var address = $('#address').val();

     // create a pointer by assigning just an ID
     var user = new Parse.User();
     user.id = user_id;

     documentUpload.set('User', user);
     documentUpload.set('Address', address);

     documentUpload.save(null, 
     {
        success: function(uploadResult) {
          // Execute any logic that should take place after the object is saved.

        },
        error: function(uploadResult, error) {
          // Execute any logic that should take place if the save fails.
          // error is a Parse.Error with an error code and description.
          alert('Failed to create new object, with error code: ' + error.description);
        }
     });
  }
