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 am trying to send data from a javascript function that generates a random string upon the page loading to a Django view. I don't know how to structure the script tag to send the data after the page has loaded and the views.py to receive the data. I am new to javascript and don't quite know how to go about this. I appreciate any help provided.
index.html
<script>
function makeid(length) {
var result = '';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
var charactersLength = characters.length;
for ( var i = 0; i < length; i++ ) {
result += characters.charAt(Math.floor(Math.random() * charactersLength));
}
return result;
}
console.log(makeid(9));
</script>
You can use ajax to send data to Django view like following code.
javascript:
function makeid(length) {
var result = '';
var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
var charactersLength = characters.length;
for ( var i = 0; i < length; i++ ) {
result += characters.charAt(Math.floor(Math.random() * charactersLength));
}
$.ajax({
type: "GET",
url: '/my_def_in_view',
data: {
"result": result,
},
dataType: "json",
success: function (data) {
// any process in data
alert("successfull")
},
failure: function () {
alert("failure");
}
});
}
urls.py:
urlpatterns = [
url(r'^my_def_in_view$', views.my_def_in_view, name='my_def_in_view'),
...
]
views.py:
def my_def_in_view(request):
result = request.GET.get('result', None)
# Any process that you want
data = {
# Data that you want to send to javascript function
}
return JsonResponse(data)
If it was successfull it goes back to "success" part.
you can do that in two ways:
Tradicional with ajax
Websockets: With django channels
If you want to send a bit of information, an ajax request is enough, you have to set and address and a view to receive the POST or GET ajax request.
I recommend to you use pure JS, not jquery
For example, this is a call to refresh a captcha image....
/*Agregar boton refresh al lado del campo input*/
let captcha_field =
document.getElementById('captcha-field-registro_1').parentNode;
let refresh_button=document.createElement('BUTTON');
refresh_button.addEventListener('click',refresh_captcha)

}
else{
console.log("Error al recibir")
}
}
};
var csrftoken = getCookie('csrftoken');
xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
xhr.setRequestHeader("X-CSRFToken", csrftoken);
xhr.send();
}
function getCookie(name) {
let cookieValue = null;
if (document.cookie && document.cookie !== '') {
var cookies = document.cookie.split(';');
for (let i = 0; i < cookies.length; i++) {
let cookie = cookies[i].trim();
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) === (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;

Someone helped me with this yesterday but it's now messed up how I send a string query to my endpoint in the AJAX call.
Functionally, this script works but by converting searchResult to an array, it screwed up my ajax call and what I send as a string query to an endpoint.
How can I modify this to make sure it sends searchResult as a string again to my ajax?
$('#productInput').on('input', function () {
let _this = $(this);
let foundOption;
let searchResult = [];
let optSelector = `option[value='${_this.val()}']`;
if (_this.val() === '') {
return;
} else if ((foundOption = $('#returnedProducts').find(optSelector)).length) {
$("#groupName").val(searchResult[$(foundOption).attr('srindex')]._source);
$("#groupNum").val(searchResult[$(foundOption).attr('srindex')]._source);
} else {
$.ajax({ url: '/account/autocomplete',
data: {
search_result: searchResult
},
"_token": "{{ csrf_token() }}",
type: "POST",
success: function (response) {
console.log(response);
let searchResult = response.hits.hits;
console.log(searchResult);
$("#returnedProducts").empty();
for(let i = 0; i < response.hits.hits.length; i++) {
$("#returnedProducts").append("<option value=" + searchResult[i]._source.category + ">" + searchResult[i]._source.category + "</option>");
}
}
});
}
});
I've been at this all day trying to figure out how to do an XMLHTTP request after authorization but just can't for the life of me figure it out.
So far I've got the code below which authorizes the user.
var OAUTHURL = 'https://accounts.google.com/o/oauth2/auth?';
var VALIDURL = 'https://www.googleapis.com/oauth2/v1/tokeninfo?
access_token=';
var SCOPE = 'https://www.googleapis.com/auth/userinfo.profile
https://www.googleapis.com/auth/userinfo.email';
var CLIENTID = 'NOT SHOWING FOR SECURITY REASONS';
var REDIRECT = 'NOT SHOWING FOR SECURITY REASONS'
var LOGOUT = 'http://accounts.google.com/Logout';
var TYPE = 'token';
var _url = OAUTHURL + 'scope=' + SCOPE + '&client_id=' + CLIENTID + '&redirect_uri=' + REDIRECT + '&response_type=' + TYPE;
var acToken;
var tokenType;
var expiresIn;
var user;
var loggedIn = false;
function login() {
var win = window.open(_url, "windowname1", 'width=800, height=600');
var pollTimer = window.setInterval(function() {
try {
console.log(win.document.URL);
if (win.document.URL.indexOf(REDIRECT) != -1) {
window.clearInterval(pollTimer);
var url = win.document.URL;
acToken = gup(url, 'access_token');
tokenType = gup(url, 'token_type');
expiresIn = gup(url, 'expires_in');
win.close();
validateToken(acToken);
}
} catch(e) {
}
}, 500);
}
function validateToken(token) {
$.ajax({
url: VALIDURL + token,
data: null,
success: function(responseText){
getUserInfo();
loggedIn = true;
$('#loginText').hide();
$('#logoutText').show();
},
dataType: "jsonp"
});
}
function getUserInfo() {
$.ajax({
url: 'https://www.googleapis.com/oauth2/v1/userinfo?access_token=' + acToken,
data: null,
success: function(resp) {
user = resp;
console.log(user);
$('#uName').text('Welcome ' + user.name);
$('#imgHolder').attr('src', user.picture);
},
dataType: "jsonp"
});
}
//credits: http://www.netlobo.com/url_query_string_javascript.html
function gup(url, name) {
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\#&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( url );
if( results == null )
return "";
else
return results[1];
}
function startLogoutPolling() {
$('#loginText').show();
$('#logoutText').hide();
loggedIn = false;
$('#uName').text('Welcome ');
$('#imgHolder').attr('src', 'none.jpg');
}
The code works fine as far as the login goes. It's after logging in that I don't know what to do. I've tried multiple ideas and have gotten nowhere. Any ideas on how I can call tags from tag manager in "readonly" mode after this login?
Hi I just decided to try using the JavaScript web app method and was able to get this working. If you run into the same issue using the ajax version here is the documentation! Make sure to select the JavaScript tab or you can try the oAuth2.

I made a JavaScript/jQuery game using that and HTML CSS. Now I am trying to integrate said game into a Django backend. Currently, I have a .js file that contains all of my Javascript/jQuery logic. It is <linked>'ed to the HTML page and basically controls the entire flow of the game.
How do I access a JavaScript variable within my .js file in my Django
.js code...
I want the this.clicks variable to be accessible in my Django view.
this.total = 18
this.clicks = 0
this.move = function(num){ //Adds or subtracts one from total depending on which player calls it
if(this.total == 0){
$('#oneone').show();
}else if(this.total == 36){
$('#twoform').show();
}else{
this.total += num
this.clicks += 1
return this.total
}
}
Django view...
class EndGame(View):
def get(self, request, victor, gameid, player1id, player2id):
print(gameid)
if int(victor) == 1: ##player one
self.TallyUpScore(1, player1id, player2id)
self.UpdateGameStats(1, gameid)
else: ##player two
self.TallyUpScore(2, player1id, player2id)
self.UpdateGameStats(2, gameid)
return redirect('/')
You need first to retrieve the csrf token:
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
then using ajax to send your data to your django view:
$.ajax({
headers: {
'Content-Type':'application/json',
'X-CSRFToken': getCookie('csrftoken')
},
url: 'here_your_view_url/' + this.clicks,
type: "GET",
success:function(response){
//alert("success: " + response);
},
error:function (xhr, textStatus, thrownError){
//alert("failure: " + xhr.statusText);
}
}).done(function (response) {
//alert("end");
});
views.py
def my_view(request):
clicks = request.GET.get('clicks')
urls.py
url(r'^here_your_view_url/(?P<clicks>\d+)', 'my_view')
I will recommend to check Django Ajax for more details.
