将输入保存到Parse(JavaScript)中

当前,当用户选择文件时,该文件将直接上传到Parse中.我现在添加了一对输入文本字段,例如个人名称,仅当用户单击选择按钮时才想同时记录到Parse中的地址,从现在开始,一旦用户选择了文件,它将自动提交.

$(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");
      }
    );
  });
});

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

解决方法:

您有两次“ 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>

至：

<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>

编辑

要回答有关记录UserId和Address字段的评论,请参见以下代码.我将文件上传绑定更改为按钮,并绑定了click事件.这将解决您选择时上传文件的问题.

另外,添加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");
                }
        );
    });

接着：

<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>
