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);}
}
}

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
Failed to load PDF document.
ts code
printItems(versionKeys: string[]): JQueryPromise<any> {
console.log('printItems');
$.ajax({

contentType: "application/json",
data: JSON.stringify(versionKeys),
url: this.apiUrls.PrintTemplates,
success: function (data, status, xhr) {
console.log('printItems');
console.log(data);
let blob = new Blob([data.Content], { type: data.ContentType });
var url = URL.createObjectURL(blob);
console.log(url);
window.open(url);
console.log('success');
}
});
return;

I converted the base64 string to a bytes
var binary_string = window.atob(data.Content)
var len = data.Content.length;
var bytes = new Uint8Array(len);
for (var i = 0; i < len; i++) {
bytes[i] = binary_string.charCodeAt(i);
}
let blob = new Blob([bytes.buffer], { type: data.ContentType })
var url = URL.createObjectURL(blob);
window.open(url);
I have an ajax call where I am calling JSReport and downloading the pdf document. In chrome and other browsers, it works correctly. The document is downloaded and I can open it. But in IE11, the document is downloaded but if I want to open the pdf file, it always shows failed to load pdf document. I debugged the code in IE11 console, but it did not give any error.
Here is my code,
$.ajax({
url: 'my api url',
headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' },
type: 'POST',
data: JSON.stringify(selectedIds),
success: function (data) {
var a = document.createElement('a');
var isIE = false || !!document.documentMode;
if (!isIE) {
// This part is working properly
for (var i = 0; i < data.length; i++) {
a.href = "data:application/octet-stream;base64," + data[i];
a.target = '_blank';
a.download = 'report.pdf';
a.click();
}
} else {
// This part is for IE11 browser where I have problem to load the document after download
for (var i = 0; i < data.length; i++) {
var file = new Blob([data[i]], {
type: 'application/octet-stream'
});
window.navigator.msSaveOrOpenBlob(file, 'report.pdf');
}
}
},
fail: function (jqXHR, textStatus) {
alert("Request failed: " + textStatus);
}
});
Finally, I found the solution! I actually needed to convert base64 string data to Blob. Then we can download it. Previously, it was not converted correctly. This was why the file was downloaded but failed to load since it was damaged. Here is my code is given below,
$.ajax({
url: 'my api url',
headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' },
type: 'POST',
data: JSON.stringify(selectedIds),
success: function (data) {
var a = document.createElement('a');
var isIE = false || !!document.documentMode;
if (!isIE) {
// This part is working properly
for (var i = 0; i < data.length; i++) {
a.href = "data:application/octet-stream;base64," + data[i];
a.target = '_blank';
a.download = 'report.pdf';
a.click();
}
} else {
for (var i = 0; i < data.length; i++) {
var base64Data = data[i];
var fileName = 'report.pdf';
var byteCharacters = atob(base64Data);
var byteNumbers = new Array(byteCharacters.length);
for (var j = 0; j < byteCharacters.length; j++) {
byteNumbers[j] = byteCharacters.charCodeAt(j);
}
var byteArray = new Uint8Array(byteNumbers);
var blob = new Blob([byteArray], { type: 'application/pdf' });
window.navigator.msSaveOrOpenBlob(blob, fileName);
}
}
},
fail: function (jqXHR, textStatus) {
alert("Request failed: " + textStatus);
}
});
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).
I'm trying to record a video (already working) using HTML5 video tag, "getUserMedia" to access the device camera and MediaRecorder API to capture the frames and Angular1 to handle the file uploading. Now I'm having trouble uploading the Blob to my PHP server which is running on Laravel, I currently have 2 ways to upload the video, first is by "ng-click" this works fine but when I programmatically upload the Blob using the same function which "ng-click" run it seems to break the mimeType of my Blob here's how my code looks.
$scope.uploader = function() {
let fData = new FormData();
let blob = new Blob($scope.chunk, { type: 'video/webm' });
fData.append('vid', blob)
$http.post(url, fData, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined},
}, success, error)
})
$timeout(function() {
$scope.uploader();
}, 10000)
This issue here is when the "$scope.uploader()" is called using "ng-click" it works fine but when calling the "uploader" method using the "$timeout" it seems to change the mimeType to "application/octet-stream" which causes the issue.
Hello Try this code,
function base64ToBlob(base64Data, contentType) {
contentType = contentType || '';
var sliceSize = 1024;
var byteCharacters = atob(base64Data);
var bytesLength = byteCharacters.length;
var slicesCount = Math.ceil(bytesLength / sliceSize);
var byteArrays = new Array(slicesCount);
for (var sliceIndex = 0;sliceIndex <slicesCount;++sliceIndex) {
var begin = sliceIndex * sliceSize;
var end = Math.min(begin + sliceSize, bytesLength);
var bytes = new Array(end - begin);
for (var offset = begin, i = 0;offset <end;++i, ++offset) {
bytes[i] = byteCharacters[offset].charCodeAt(0);
}
byteArrays[sliceIndex] = new Uint8Array(bytes);
}
return new Blob(byteArrays, {
type: contentType});
}
Define scope
$scope.onFile = function(blob) {
Cropper.encode((file = blob)).then(function(dataUrl) {
$scope.dataUrl = dataUrl;
$scope.odataUrl = dataUrl;

Thanks, the issue was caused by upload and post limit in my php.ini.

});
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.
