没有在javascript中接收帖子数据嵌入表单

Question

function editProfile() {
var clearBackground = document.createElement("div");
    clearBackground.setAttribute("id","clearBackgroundEdit");
    document.body.appendChild(clearBackground);

var div = document.createElement("div");
    div.setAttribute("id","editProfileContainer");
    div.innerHTML = `
    <div id="listOfOptions">
    <span class="editProfileTitle">Main Options</span>
    <div id="chooseOptions">
        <ul>
            <li id="profilePhotoEdit">Choose Profile Photo</li>
            <li id="changePasswordEdit">Change Password</li>
        </ul>
    </div>
    </div>


    <div id="uploadProfileImage">


    <span class="editProfileTitle">Upload A Profile Photo</span>

    <div id="photoUploadContainer">

    <label class="fileUploader">
    Select a Profile Image
    <input name="profileImage" id="profileImage" class="fileUploader" type="file" />
    </label>
    <input type="text" name="filePath" id="filePath" value="No File" disabled="true" />
    <span class="uploadPhoto" id="uploadPhoto">Upload</span>

    </div>

    <i id="backOptions" class="backOptions fa fa-chevron-circle-left fa-3x" aria-hidden="true"></i>

    </div>

    `;

    document.body.appendChild(div);
    JS.addListener("click","profilePhotoEdit",function() {
        JS.g("listOfOptions").style.cssText="display:none;";
        $("#editProfileContainer").animate({height: "200px", width: "900px"},function(){
            JS.g("uploadProfileImage").style.cssText="display:block;";
        });
        JS.addListener("click","uploadPhoto",goPhotoUpload);
    });
    JS.addListener("change","profileImage",function(){
        var fileType = JS.g("profileImage").value.split(".").pop().toLowerCase();

        if(fileType == "jpg" || fileType == "jpeg" || fileType == "png" || fileType == "gif") {

        if(JS.g('profileImage').value.length >=1) {

            JS.g("filePath").value = JS.g("profileImage").value;
        }
        else {
            JS.g("filePath").value = "No File";
        }

        }
        else {
            JS.g("filePath").value = "No File";
            JS.g("profileImage").value = null;
            oops("Must be a valid file type: jpg, gif, png","uploadProfileImage","152px;","400px");

        }
    });
    JS.addListener("click","clearBackgroundEdit",closeEditProfile);
    JS.addListener("click","backOptions",function(){
        JS.g("uploadProfileImage").style.cssText="display:none;";
        $("#editProfileContainer").animate({height: "150px", width: "500px"},function(){
        JS.g("listOfOptions").style.cssText="display:block;";
        JS.g("filePath").value="No File";
        });
    });
 }

 function goPhotoUpload() {
var fileType = JS.g("profileImage").value.split(".").pop().toLowerCase();

if(fileType == "jpg" || fileType == "jpeg" || fileType == "png" || fileType == "gif") {
    var uploadForm = document.createElement("form");
        uploadForm.setAttribute("method","post");
        uploadForm.setAttribute("action","/server/profilePhotoUpload.php");
        uploadForm.setAttribute("name","profilePhoto");
        uploadForm.setAttribute("id","profilePhoto");
        uploadForm.setAttribute("enctype","multipart/form-data");
        uploadForm.setAttribute("target","uploadIframe");
        document.getElementById('photoUploadContainer').appendChild(uploadForm);


    var iframe = document.createElement("iframe");
        iframe.setAttribute("id","uploadIframe");
        iframe.setAttribute("name","uploadIframe");
        iframe.setAttribute("width","500");
        iframe.setAttribute("height","500");
        iframe.setAttribute("style","display:block; width:500px; height:500px;");

        document.body.appendChild(iframe);

        JS.g("profilePhoto").submit();

        document.getElementById("uploadIframe").onload = function() {

            alert("Its fully loaded");

        }


}

else {
            JS.g("filePath").value = "No File";
            oops("Must be a valid file type: jpg, gif, png","uploadProfileImage","152px;","400px");

        }

 }

  function closeEditProfile() {
  if(JS.g("editProfileContainer") && JS.g("clearBackgroundEdit")) {
    $("#editProfileContainer").remove();
    $("#clearBackgroundEdit").remove();
  }
   }

   JS.load(function() {
   JS.addListener("click","editProfileButton",editProfile);
   })

iframe正在加载到右侧页面，但没有发布到页面的帖子数据。我现在一直在敲桌子约6个小时，不知道我可能会错过什么或者做错了。这里的目标是将post $ _FILE发送到profilePhotoUpload.php页面，以便我的PHP脚本可以处理请求。但同样，没有帖子数据进入页面。

感谢您的帮助。
