file upload in javascript and send file through api

file upload in javascript and send file through api - javascript

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.

Failed to load PDF but can see the data

I am getting this error that Chrome failed to load the PDF document. I can see the content of the data is the console window so I have the data being returned I just not sure why it will not display? If I File.WriteAllBytes to disk it will open fine so it maybe something with the creating the new Blob

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).

if (Photo_Path == "") {
alert('Please Choose Photo');
return;
}
if (extenssion != 'JPEG' && extenssion != 'JPG' && extenssion != 'jpg') {
alert('Invalid File[JPEG,JPG is acceptable]');
return;
}
if (file.size < 4000 || file.size > 14000) {

how receive json in jquery success method and use that json to build html content

I am working on an java spring application that requires the controller to return json. By receiving that json in jquery success method, I want to make html out of it.
controller returns a json like below:
return "[{\"Id\": \"1\", \"Name\": \"Apples\"}, {\"Id\": \"2\", \"Name\":\"Mangoes\"}]";
jquery used to hit that controller and then receive the json in success method:
var content;
$(document).ready(function(){
$("#submitButton").click(function(e){
var formData = getFormData();
if(formData!=false){
$.ajax({
type: 'POST',
'url': 'http://localhost:8080/Test_ReportingUI/fieldMappingNext.htm',
data: {jsonData: JSON.stringify(formData)},
dataType: 'json',
success: function(response){
for (var x = 0; x < response.length; x++) {
content = response[x].Id;
content += "<br>";
content += response[x].Name;
content += "<br>";
$(content).appendTo("#Fruits");
}
},
timeout: 10000,
error: function(xhr, status, err){
if(response.status=='timeout')
{
alert('Request time has been out','');
}
console.log(status,err);
}
}); }
});
});
below is the HTML div where I want to use above content to append:
<div id="Fruits">
fruits :
</div>
it is reaching to the controller. and also returning json. but I am not able to use that json.

Replace your for loop with
for (var x = 0; x < response.length; x++)
{
content = "<div class='fruit'><div>" + response[x].Id + "</div>";
content += "<div>" + response[x].Name + "</div></div>";
$(content).appendTo("#Fruits");
}
Your error message correctly explained that you were not appending the correct expression into the fruits

try below code
$(document).ready(function() {
$("#submitButton").click(function(e) {
var formData = getFormData();
if (formData != false) {
$.ajax({
type: 'POST',
'url': 'http://localhost:8080/Test_ReportingUI/fieldMappingNext.htm',
data: {
jsonData: JSON.stringify(formData)
},
dataType: 'json',
success: function(response) {
for (var x = 0; x < response.length; x++) {
var fContent = $("<div></div>");
var id = $("<span></span>").text(response[x].Id);
var name = $("<span></span>").text(response[x].Name);
fContent.append(id)
fContent.append(name);
$("#Fruits").append(fContent);
}
},
timeout: 10000,
error: function(xhr, status, err) {
if (response.status == 'timeout') {
alert('Request time has been out', '');
}
console.log(status, err);
}
});
}
});
});

Facebook photo upload with JavaScript is not working

I need to write a javascript code for construct 2 plugin. below is my code :
Acts.prototype.PublishToWallPHOTO = function (snapshotdata)
{
if (this.runtime.isDomFree || !fbLoggedIn)
return;
var blob;
try
{
blob = dataURItoBlob(snapshotdata.replace("data:image/png;base64,", ""),'image/png');
}
catch(e){console.log(e);}
FB.api('/me/photos', 'POST', {
message:'photo description',
source:blob
}, function(response) {
if (!response || response.error)
console.error(response);
});
};
function dataURItoBlob(dataURI,mime)
{
var byteString = window.atob(dataURI);
var ia = new Uint8Array(byteString.length);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
var blob = new Blob([ia], { type: mime });
return blob;
}
for above code parameter for "snapshotdata" look like this : "data:image/png;base64,iVBORw0KGgoAAAA.........."
But my image was not uploaded to facebook using above code. but with same code if I use url:'http://example.com/abc.png' instead of source:blob then it upload a image in given URL successfully. I was tried to find the wrong with above code, but i was unable to find a proper solution. Please tell me if any one know the issue with above code.
ps: sorry for poor English

Maybe a FormData() does the trick.
function uploadPicture(response) {
if (response.status === 'connected') {
var blob = dataURItoBlob(imageHolder.imageElement.dom.src.replace("data:image/png;base64,", ""),'image/png');
var fd = new FormData();
var token = response.authResponse.accessToken;
fd.append("access_token",token);
fd.append("source\"; filename=\"" + "test.png" + "\"", blob);
fd.append("message","Test");
try{
$.ajax({
url:"https://graph.facebook.com/me/photos?access_token=" + token,
type:"POST",
data:fd,
processData:false,
contentType:false,
cache:false,
success:function(data){
console.log("success " + data);
},
error:function(shr,status,data){
console.log("error " + data + " Status " + shr.status);
},
complete:function(){
console.log("Ajax Complete");
}
});
}catch(e){console.log(e);}
}
}
