Accessing the Forge Viewer From Two HTML Files

I have been working on a website incorporating the autodesk-forge viewer (more details can be seen on my past questions). I have successfully made many autodesk-forge viewer functions in a standard javascript (.js) file. These functions include displaying the viewer, and isolating to a particular part, when an external button is pressed.
Currently I have a main html/php home page where I have included my javascript file with all my forge functions using <script src="MyForgeFunctions.js"></script>
These functions are accessed through a button, which successfully displays the viewer in the html page. Attached to my main php/html page, another html/php page was added through an iframe html reference (<iframe src="URL.php"></iframe>). My home page displays the main machines we make, while the embedded php/html page displays all the stations within the machine. I have also included the MyForgeFunctions.js inside this second php/html page. Because of the way the website is set up, I need to be able to access the viewer in both web pages. However, when I attempt to access the viewer from the second html page, I get a message that the viewer is undefined. Below is my code from MyForgeFunctions.js.
var ext = '';
var dim = '';
var assemblyname = '';
function getAssemblyName(){
assemblyname = sessionStorage.getItem("assemblyName");
//var ext = partname.substr(partname.lastIndexOf('.'));
ext = assemblyname.split('.');
dim = ext[0] + ':1';
console.log(assemblyname);
console.log(dim);
if (dim !== ''){
isolateSelected();
}
}
//function to get part name from __MachineParts.php
var partname = '';
var extension = '';
var namewithoutextension = '';
function getPartName(){
partname = sessionStorage.getItem("partName");
//var ext = partname.substr(partname.lastIndexOf('.'));
extension = partname.split('.');
namewithoutextension = extension[0] + ':1'
console.log(partname);
console.log(namewithoutextension);
if (namewithoutextension !== ''){
isolateSelectedPart();
}
}

Because of how the webpage is set up, when I needed to use a variable from the second web page in the first, I used sessionStorage.getItem and sessionStorage.setItem. I have also made a simple function as so inside MyForgeFunctions.js:
function checkViewer(){
console.log(viewer);
}
I then included a button in both html pages to execute the function with an onclick event. When the function is run from the first/home html page the following is displayed:
T {globalManager: e, clientContainer: div#forgeViewer, container: div.adsk-viewing-viewer.notouch.dark-theme.quality-text, config: {…}, contextMenu: o, …}. Which is normal for the viewer, but when the function is executed from the second html page, the viewer is undefined. Any help as to why this is happening or any solutions will be greatly appreciated. Cheers!

From the iframe, in order to access the viewer inside the main web page, I had to use (parent.viewer).

how to specify which files should be uploaded onn file upload using javascript or jquery

I am uploading files onto a folder within my application using the code below. I would like to know how I can specify which type of files can be uploaded into that folder in my case I only want the user to be able to upload xls,xlxs and csv files. The user should not be allowed to upload docx or images etc
function OnUpload(evt) {
var files = $("#fileUpload").get(0).files;
if (files.length > 0) {
ShowUploadProgress();
if (window.FormData !== undefined) {
var data = new FormData();
for (i = 0; i < files.length; i++) {
data.append("file" + i, files[i]);
}
$.ajax({
type: "POST",
//url: "/api/ExcelBulkUpload",
url: "/api/FileUpload",
contentType: false,
processData: false,
data: data,
success: function (results) {
ShowUploadControls();
$("#uploadResults").empty();
for (i = 0; i < results.length; i++) {
$("#uploadResults").append($("<li/>").text(results[i]));
}
///"location.href='<%: Url.Action("Upload", "Controller") %>'"
window.location.href = '#Url.Action("UploadPage", "Home")';
},
error: function (xhr, ajaxOptions, thrownError) {
ShowUploadControls();
alert(xhr.responseText);
}
});
} else {
alert("Your browser doesn't support HTML5 multiple file uploads! Please use another browser.");
}
}
}
What I have researched so far
_validFileExtensions = [".xls", ".xlsx"];
var sFileName = oInput.value;
if (sFileName.length > 0) {
var blnValid = false;
for (var j = 0; j < _validFileExtensions.length; j++) {
var sCurExtension = _validFileExtensions[j];
if (sFileName.substr(sFileName.length - sCurExtension.length, sCurExtension.length).toLowerCase() == sCurExtension.toLowerCase()) {
blnValid = true;
//$('#fileinput').val('');
break;
}

You can check file extension, and based on that if file extension are allowed then call upload function, else display message that selected file not allowed to upload.
Se below example.
Note : Only client side validation is not enough, also put validation on server side.
$(document).on("change","#myfile", function (e) {
var _theFormFile = $('#myfile')[0].files[0];
var ext = getExt(_theFormFile.name);
if(ext == ".xls" || ext == ".xlxs " || ext == ".csv") {
alert('call upload file function');
} else {
alert('display false message')
return false;
}
});
function getExt(filename) {
var ext = filename.split(".");
var cnt = ext.length;
ext = ext[cnt - 1];
ext = "." + ext.toLowerCase();
return ext;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type='file' name="myfile" id="myfile">

First you can select what file types the users can input by default with
<input accept=".fileType" />
And then check the filetyp if they changed the filter
function upload(){
var fileName = document.getElementById("file").files[0].name;
console.log(fileName.substr(fileName.lastIndexOf(".")));
}
<input id="file" type="file" accept=".xls,.xlxs,.csv" />
<button onClick="upload()">send</button>

Setting Uploaded Image as Background using Javascript in ASP.NET MVC

In my application, I have so far managed to upload images to the server. Now I would like to set an uploaded image as a background dynamically using javascript in ASP.NET MVC5. Here is my code. This part reads file from local storage
jQuery(document).ready(function ()
{
jQuery("#imageBrowes").change(function ()
{
var File = this.files;
if (File && File[0])
{
ReadImage(File[0]);
}
})
})
var ReadImage = function(file)
{
var reader = new FileReader;
var image = new Image;
reader.readAsDataURL(file);
reader.onload = function(_file)
{
image.src = _file.target.result;
image.onload = function()
{
var height = this.height;
var width = this.width;
var type = file.type;
var size = ~~(file.size / 1024) + "KB";
jQuery("#targetImg").attr('src', _file.target.result);
jQuery("#description").text("Size:" + size + ", " + height + "X " + width + ", " + type + "");
jQuery("#imgPreview").show();
}
}
}
This part stores the image into the file server system:
var ClearPreview = function(){
jQuery("#imageBrowes").val('');
jQuery("#description").text('');
jQuery("#imgPreview").hide();
}
var Uploadimage = function()
{
var file = jQuery("#imageBrowes").get(0).files;
var data = new FormData;
data.append("ImageFile", file[0]);
jQuery.ajax({
type: "Post",
url: "/Home/ImageUpload",
data: data,
contentType: false,
processData: false,
success: function (response) {
ClearPreview();
jQuery("#uploadedImage").append('<img src="/elements-images/' + response + '" class="img-responsive thumbnail"/>');
}
})
}
This the action that is called up in the above javascript:
public ActionResult ImageUpload(ProductViewModel model)
{
var file = model.ImageFile;
if (file != null)
{
var fileName = Path.GetFileName(file.FileName);
var extention = Path.GetExtension(file.FileName);
var filenamewithoutextension = Path.GetFileNameWithoutExtension(file.FileName);
file.SaveAs(Server.MapPath("/elements-images/" + file.FileName));
}
return Json(file.FileName, JsonRequestBehavior.AllowGet);
}
So basically the image file is saved into elements-images folder. How do I then set a specific image from that folder into a background image?

Javascript side preview
For javascript side preview of the file, Please change your this line
jQuery("#targetImg").attr('src', _file.target.result);
to
jQuery("#targetImg").attr('src', "data:" + file.type + ";base64," + btoa(_file.target.result) );
Preview after upload on server
To show image after server response your code seems to be correct. It seems you need to change this line in action result
return Json(file.FileName, JsonRequestBehavior.AllowGet);
so it looks like this
public ActionResult ImageUpload(ProductViewModel model)
{
var file = model.ImageFile;
string fileName = string.Empty;
if (file != null)
{
fileName = Path.GetFileName(file.FileName);
var extention = Path.GetExtension(file.FileName);
var filenamewithoutextension = Path.GetFileNameWithoutExtension(file.FileName);
file.SaveAs(Server.MapPath("/elements-images/" + file.FileName));
}
return Json(fileName, JsonRequestBehavior.AllowGet);
}

file upload in javascript and send file through api

I'm trying to upload a file and send that via api as a file.But not getting working. Here is my used for upload and send my file to api.
But it most probably terns to the error message.
$(document).on('change', '#txtUploadFile', function(e){
var files = e.target.files;
if (files.length > 0) {
if (this.value.lastIndexOf('.xlsx') === -1){
alert('Only ods files are allowed!');
this.value = '';
return;
}
if (window.FormData !== undefined) {
var data = new FormData();
for (var x = 0; x < files.length; x++){
data.append("file" + x, files[x]);
}
$.ajax({
type: "POST",
contentType: "multipart/form-data",
url: 'http://localhost/clicportaltest/rest/clicadmin/uploadExcel',
data:{file:file},
success: function(result) {
console.log(result);
},
error: function (xhr, status, p3, p4){
var err = "Error " + " " + status + " " + p3 + " " + p4;
if (xhr.responseText && xhr.responseText[0] == "{")
err = JSON.parse(xhr.responseText).Message;
console.log(err);
}
});
} else {
alert("This browser doesn't support HTML5 file uploads!");
}
}
});

$(function(){
$('#submitUpload').on('click', function(){
var file = document.getElementById("upload").files[0];
var form = new FormData();
form.append("file", file);
var settings = {
"async": true,
"crossDomain": true,
"url": "http://localhost/clicportaltest/rest/clicadmin/uploadExcel",
"method": "POST",
"processData": false,
"contentType": false,
"mimeType": "multipart/form-data",
"data": form
};
$.ajax(settings).done(function (response) {
console.log(response);
});
});
});

You can't JSON.stringify data because FormData doesn't have a toJSON() method, so it is treated as a plain object which results in "{}".
You can either implement your own FormData.prototype.toJSON method or just convert data to a string or a plain object in your handler. How the stringified representation of data should be formatted depends entirely on how your API expects it to be.

AJAX Requests to php script

So the problem is: a user uplaods a file. I use е.PreventDefault(); to prevent the page from refreshing after the upload. Under the file upload form i've made a list of all the user's file names. Obviously the newly uploaded file name isn't in the list. After refreshing the page it gets in the list, but the business logic is that the file's name should go in the list withouth refreshing the page.
function showNewFileProperies() {
var xhttp;
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
document.getElementById("results").innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", "../../app/Models/UserFiles.php" , true);
xhttp.send();
}
This is the request with which I thought my problem would be solved.
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class UserFiles extends Model{
protected $table = 'files';
public function getUserFiles(){
$getFiles = Filecontent::where('userid', Auth::id())->get();
foreach($getFiles as $getFile) {
$result = $getFile->filename;
return $result;
}
}
}
I'm using Laravel and Dropzone.js. The js code i put in the success event of dropzone.js

Sorry for the delay in response. Here is what I used to achieve what you are describing. Sorry for the bad indenting but this editor is really bad.
Dropzone.options.documentDropzone = {
paramName: "file",
dictDefaultMessage: "Drag your document over this box to upload or click here",
maxFilesize: 100, // MB
maxFiles: 10,
addRemoveLinks: true,
dictRemoveFile: 'Remove Attachment',
accept: function(file, done) {
done();
},
init: function() {
this.on("addedfile", function(file) {
busy_uploading = true;
});
this.on('removedfile', function(file){
remove_file(file.previewElement, file.fileID);
if(this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0) {
busy_uploading = false;
}
});
this.on("complete", function (file) {
if(this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0) {
busy_uploading = false;
}
});
},
success: function(file, response) {
response = JSON && JSON.parse(response) || $.parseJSON(response);
if(response.error) {
var node, _i, _len, _ref, _results;
var message = response.error;
file.previewElement.classList.add("dz-error");
_ref = file.previewElement.querySelectorAll("[data-dz-errormessage]");
_results = [];
for (_i = 0, _len = _ref.length; _i < _len; _i++) {
node = _ref[_i];
_results.push(node.textContent = message);
}
return _results;
} else {
for(var i = 0; i < response.file_id.length; i++) {
file.fileID = response.file_id[i];
file.fileEXT = response.file_ext[i];
add_file_id(response.file_id[i]);
//You can add the uploaded item in your list here
}
return file.previewElement.classList.add("dz-success");
}
}
};
So this is roughly what I used. You can simply add the item on your list in the success function since that is where you will get the response from the server.
I did not include the php because it is just your basic upload script. This will work with as many files as you wish.
If you need more help just add a comment and I will try to assist you as best I can.

Actually I came up with this:
public function getCurrentFile(){
$userid = Auth::id();
$getFiles = File::where('userid', $userid)->orderBy('created_at', 'desc')->take(1)->get();
foreach($getFiles as $getFile) {
$result = $getFile;
$json = json_encode($result); //make it as json
return $json;
//echo $result;
}
}
Then I routed this model and in the js I've added:
success: function(file) {
$(function ()
{
$.ajax({
async: true,
url: "../public/currentfile",
dataType: 'json',
method:'get',
complete: function(data)
{
console.log(data.responseJSON);
var created_at = data.responseJSON['created_at'];
var filesize = data.responseJSON['filesize'];
var filename = data.responseJSON['filename'];
var fileid = data.responseJSON['fileid'];
$( "#results .tableheaders" ).after("<tr><td>" + fileid + "</td><td>" + filename + "</td><td>" + filesize + "</td><td>" + created_at + "</td></tr>");
}
});
});
if (file.previewElement) {
return file.previewElement.classList.add("dz-success");
}
}
And it seems to work...for now :D I'm not a JS guy and I don't even know how I managed to do this :D
