无法正确格式化AJAX POST请求

时间:2017-08-24 12:42:00

标签: javascript jquery ajax

无论我做什么,我在尝试执行500 (Internal Server Errors)POST时都会https://rates.tradelanes.us/bankaccount/record/create。我相信它的数据格式,但当我比较我的输出与其他人尝试同样的事情时 - 我的数据格式是相同的;其他人没有得到500 error,所以必须是我的数据格式化。我使用API​​的唯一文档是https://rates.tradelanes.us/bankaccount/help/api - 所以继续下去还不多。

Here is the error I'm getting.。如果您想查看示例记录的样子:

{"Id":1,"Memo":"Sample Record","Amount":10.00,"TransactionDate":"\/Date(1503500694627)\/","Account":1,"Transaction":0}

这是我的代码:



$(document).ready(function() {
  var table_records = $("#table_records").dataTable({
    "processing": true,
    "ajax": {
      "url": "https://rates.tradelanes.us/bankaccount/records",
      dataSrc: ""
    },
    "columns": [{
      "data": "Id"
    }, {
      "data": "Memo"
    }, {
      "data": "Amount"
    }, {
      "data": "TransactionDate"
    }, {
      "data": "Account"
    }, {
      "data": "Transaction"
    }]
  });

  //Show popup for creating new record
  function show_lightbox() {
    $(".lightbox_bg").show();
    $(".lightbox_container").show();
  }

  //Hide popup for creating new record
  function hide_lightbox() {
    $(".lightbox_bg").hide();
    $(".lightbox_container").hide();
  }

  //Clicking the "Close" button or outside of the lightbox should close the lightbox
  $(document).on("click", ".lightbox_bg", function() {
    hide_lightbox();
  });
  $(document).on("click", ".lightbox_close", function() {
    hide_lightbox();
  });

  //Handle clicking the "Create" button
  $(document).on("click", "#createButton", function(e) {
    e.preventDefault();
    $(".lightbox_content h2").text("Create record");
    $("#form_create button").text("Create record");
    $("#form_create").attr("class", "form add");
    $("#form_create").attr("data-id", "");
    $("#form_create .field_container").removeClass("valid").removeClass("error");
    $("#form_create #id").val("");
    $("#form_create #memo").val("");
    $("#form_create #amount").val("");
    $("#form_create #transactiondate").val("");
    $("#form_create #account").val("");
    $("#form_create #transaction").val("");
    show_lightbox();
  });

  function getFormData($form) {
    var unindexed_array = $form.serializeArray();
    var indexed_array = {};

    $.map(unindexed_array, function(n, i) {
      indexed_array[n['name']] = n['value'];
    });

    return indexed_array;
  }

  //Handle form submission
  $(document).on("submit", "#form_create.add", function(e) {
    e.preventDefault();
    hide_lightbox();

    var $form = $("#form_create");
    var form_data = getFormData($form);
    console.log(form_data);

    var req = $.ajax({
      url: "https://rates.tradelanes.us/bankaccount/record/create",
      cache: false,
      data: form_data,
      dataType: "application/json",
      contentType: "application/json; charset=utf-8",
      type: "post"
    });

    req.done(function(out) {
      if (out.result == "success") {
        table_records.api().ajax.reload(function() {
          alert("Record added successfully");
        }, true);
      } else {
        alert("Record failed to be created");
      }
    });

    req.fail(function(jqXHR, textStatus, errorThrown) {
      console.log(jqXHR.statusText);
      console.log(textStatus);
      console.log(errorThrown);
    });
  });

答案是显然删除了AJAX请求的所有settings。谁会想到?

所以它应该如下所示:

var req = $.ajax({
      url: "https://rates.tradelanes.us/bankaccount/record/create",
      dataType: "json",
      data: form_data,
      type: "POST"
});

答案 1 :(得分:-1)

你必须确定你收到了表格。

let form = $('.whatever').find('form');

然后将数据作为序列化表单传递

form.serialize()

var req = $.ajax({
      url: "https://rates.tradelanes.us/bankaccount/record/create",
      cache: false,
      data: form.serialize(),
      dataType: "application/json",
      contentType: "application/json; charset=utf-8",
      type: "post"
    });

    req.done(function(out) {
      if (out.result == "success") {
        table_records.api().ajax.reload(function() {
          alert("Record added successfully");
        }, true);
      } else {
        alert("Record failed to be created");
      }
    });
