OK, the docs are messy at best. I have huge issues fading in and out preloaded assets if I do not add 'false' to the instance of PreloadJS. But when I add it I completely lose the progress event ... what is it that's so deeply hidden in the docs, that I cannot find anything about this?
And has anyone got a complete example of HOW to actually and properly load an array (actually an object) of images without losing the progress event AND still have an asset that behaves as expected when adding it to the DOM and fade it in?
This was also posted in a question on GitHub.
The short answer is that loading with tags (setting the first param useXHR to false) doesn't support granular progress events because downloading images with tags doesn't give progress events in the browser.
You can still get progress events from the LoadQueue any time an image loads, but each image will just provide a single "complete" event.
#Lanny True for that part, but in my case I was also missing the 'true' in .getResult(), and the createObjectURL() for the image data:
…
var preloader = new createjs.LoadQueue();
…
…
function handleFileLoad ( e ) {
var item = e.item,
result = preloader.getResult(item.id, true),
blob_url = URL.createObjectURL( result );
…
So, that I was actually able to handle the image data as a blob … I couldn't find anything close to 'createObjectURL' in the docs. I guess that renders the docs 'not complete' at best …

How do I add a clickable link to any of the image slices so the user can click a slice to go to a url? Currently they can spin the wheel to get a random url choice. I got the random spin part working using “IF” but I got stuck figuring out the image slice click idea.
I'm currently working at the top of page in an area called:
//add code here?
if (clickedSegment) {
clickedSegment.indicatedSegment = "Jane";
window.location = "https://www.mikeloucas.com";
theWheel.draw();
and I have one url working due to the "clickedSegment" but it's active on all the slices and not what I need (I'm try to target Jane) so I'll keep at it unless some has an answer.
Separately but related:
This is one of the image segments I'm trying to add add link to:
{'image' : 'https://mikeloucas.com/wheel/jane.png', 'text' : 'Jane'},
The original tutorial shows how to change the colour of a slice on click, but I’d like to go to a url instead.
Original Click Code: http://dougtesting.net/winwheel/docs/tut15_get_segment_clicked
The thing Im working on: https://codepen.io/mikeloucas/pen/qBarWoP
In my Codepen example I turned off the “IF” load url because its just in the way when testing, but feel free to turn it on see it in action. It’s WAY down the page lol; you’ll see:
if (indicatedSegment.text == "Jane") {
window.location = "https://www.mikeloucas.com";
WAS:
let clickedSegment= theWheel.getSegmentAt(e.clientX, e.clientY);
if (clickedSegment) {
clickedSegment.indicatedSegment = "Jane";
window.location = "https://www.mikeloucas.com";
theWheel.draw();
IS NOW:
let segmentImage = theWheel.getSegmentAt(e.clientX, e.clientY);
if (segmentImage.text == "Jane") {
window.location = "https://www.mikeloucas.com";}
else if (segmentImage.text == "othername")...{
}
...theWheel.draw();
The trick (for me) was changing "clickedSegment" to "segmentImage" because "segmentImage" was already calling the array of names. I also add an "ELSE IF" because I had lots of slices to work work with.
See working thingy here: https://codepen.io/mikeloucas/pen/qBarWoP
My version needs to have the URL and NAME LIST entered twice; it would be cool if someone knows how to do it once (one set instead of two) but maintain both functions of the "CLICK url" and "SPIN url", so I'm still open to advice.
I'd prefer one set over two. :-)
I'm using NgBlockUI and BlockUIHttpModule with blockAllRequestsInProgress set to true in an app I'm working on. In general it's working fine, but on one page I'm using a concat map to perform some action and then update the data. The first request, the update, triggers BlockUI fine, but the second one doesn't. Otherwise, it executes properly. It's just a little jarring for the user since the results seem to update without warning. Here's the code for the function:
onUpdate(event: items[]) {
this.updateService.update(event).concatMap(
_ => this.seachService.search(this.cachedSearch)
).subscribe(
resp => this.handleResponse(resp),
err => this.handleError(err)
);
}
I tried calling BlockUI directly, but still no luck. As a last resort, I'm going to make the whole thing one request, but I'd like to at least understand why this isn't working.
This happened to me as well. This issue occurs for sequential HTTP calls (usually with await) wherein the second request is not blocked by ng-block-ui.
As fix what I did was set blockAllRequestsInProgress to false. The behavior is just the same but setting it to false yields more predictable results:
BlockUIHttpModule.forRoot({
blockAllRequestsInProgress: false,
requestFilters: [urlFilter]
}),
I've also updated to ng-block-ui to latest version as of this writing:
"ng-block-ui": "^2.1.8",
Just new in Prestashop (1.6.0.6), I've a problem with my product page in admin. All translatable-field are to display:none (I inspect the code with chrome).
So when I want to create a new product I can't because the name field is required.
I thought that it was simple to find the .js whose do that but it isn't.
If somebody could help me, I would be happy.
Thank you for your help
Hi,
I make some searches and see that the function hideOtherLanguage(id) hide and show translatable-field element.
function hideOtherLanguage(id)
{
console.log(id_language);
$('.translatable-field').hide();
$('.lang-' + id).show();
var id_old_language = id_language;
id_language = id;
if (id_old_language != id)
changeEmployeeLanguage();
updateCurrentText();
}
When I set the Id to 1 (default language), it works. It seems that when I load the page, the function is called twice and the last calling, the id value is undefined. So the show() function will not work.
If somebody could help me. Thank you.
In my console, I see only one error
undefined is not a function.
under index.php / Line 1002
...
$("#product_form").validate({
...
But I find the form.tpl template and set this lines in comment but nothing change.
EDIT: According to comment on this link http://forge.prestashop.com/browse/PSCFV-2928 this can possibly be caused by corrupted installation file(s) - so when on clean install - try to re-download and reinstall...
...otherwise:
I got into a similar problem - in module admin page, when creating configuration form using PrestaShop's HelperForm. I will provide most probable cases and their possible solutions.
The solution for HelperForm was tested on PS 1.6.0.14
Generally there are 2 cases when this will happen.
First, you have to check what html you recieve.
=> Display source code - NOT in developer tools/firebug/etc...!
=> I really mean the pure recieved (JavaScript untouched) html.
Check if your translatable-fields have already the inline style "display: none":
Case 1 - fields already have inline style(s) for "display: none"
This means the template/html was already prepared this way - most probably in some TPL file I saw codes similar to these:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $id_lang_default}style="display:none"{/if}>
Or particularly in HelperForm template:
<div class="translatable-field lang-{$language.id_lang}"
{if $language.id_lang != $defaultFormLanguage}style="display:none"{/if}>
Case 1 is the most easy to solve, you just have to find, where to set this default language.
Solutions
HelperForm
Look where you've (or someone else) prepared the HelperForm object - something like:
$formHelper = new HelperForm();
...
Somewhere there will be something like $formHelper->default_form_language = ...;
My wrong first solution was to get default form language from context - which might not be set:
$this->context->controller->default_form_language; //THIS IS WRONG!
The correct way is to get the default language from configuration - something like:
$default_lang = new Language((int)Configuration::get('PS_LANG_DEFAULT'));
$formHelper->default_form_language = $default_lang->id;
...this particularly solved my problem...
Other form-creations
If there is something else than HelperForm used for form creations, the problem is still very similar.
You have to find where in files(probably tpls) is a condition for printing display:none for your case - then find where is the check-against-variable set and set it correctly yourself.
Case 2 - fields don't have inline style(s) for "display: none"
This means it is done after loading HTML by JavaScript. There are two options:
There is a call for hideOtherLanguage(), but there is wrongly set input language - that means no language will be displayed and all hidden.Solution for this one can be often solved by solving Case 1 (see above). In addition there can be programming error in not setting the after-used language id variable at all... then you would have to set it yourself (assign in JavaScript).
Some script calls some sort of .hide() on .translatable-field - you will have to search for it the hard way and remove/comment it out.
PS: Of course you can set the language to whatever you want, it is just common to set it to default language, because it is the most easier and the most clear way how to set it.
I have a list of products that I download as json file from server. Each item contains a link to the image stored on server.
Now I want to be able to see the products when offline, so I store downloaded json file into forge.prefs http://docs.trigger.io/en/v1.3/modules/prefs.html and pull it out to display items on screen. It works nice but I also need to store images localy to be displayed correctly.
To achive this, I'm trying to use forge.file.cacheURL http://docs.trigger.io/en/v1.3/features/cache.html but can't handle the correct order of operations. To cache images I run the json file and for each line I call forge.file.cacheURL and store the url back to JSON item. But here is the problem as forge.file.cacheURL runs asynchronously so my loop running over the items and gathering the local images finishes and my code continues to display images(view items) but meantime the forge.file.cacheURL still gathers and caches the images because its asynchronous operation. I need somehow to detect that last item is being cached and then refresh the view on screen to use correct image urls ... or something else that will lead to what I need.
Hopefully you understand the concept. How should I handle this properly ?
Since v1.4.26 you've been able to permanently store images (see http://docs.trigger.io/en/v1.4/release-notes.html#v1-4-26), rather than just cache them. Depending on your needs, that might be a better option than forge.file.cacheURL and forge.file.isFile.
I don't follow exactly the situation you describe, but something like this will let you wait for several asynchronous things to finish before doing something:
// e.g.
var jsonCache = {
one: "http://example.com/one.jpg",
two: "http://example.com/two.jpg",
three: "http://example.com/three.jpg"
};
var cacheCount = 0;
for (var name in jsonCache) {
if (jsonCache.hasOwnProperty(name)) {
var imageURL = jsonCache[name];
cacheCount += 1;
forge.file.cacheURL(imageURL, function (file) {
forge.prefs.set(name, file, function () {
cacheCount -= 1; // race condition, but should be fine (!)
if (cacheCount <= 0) {
alert('all cached');
}
});
});
}
}
i have two volumes (.nrrd) of different qualities. the user can browse through the layers. if a key is pressed
i want to load the slice of the volume with better quality.
my volume is similar to this one: lesson 10 xtk
i've found:
volume.children[2].children[0].children[0].texture.file = "http://path/to/file.ext";
but if i apply some kind of file (.jpg, .dcm) nothing happens.
is this the right approach to change the slice to go inside the children and change the texture?
or shall i load the selected slice seperate as an object and apply it to the "lower-quality-volume" somehow?
edit:
this is what i tried so far (i get errors with dcms but not with jpgs):
if (event.keyCode == 83) { // "s"-button
volume.children[2].children[0].children[0].texture.file = "http://localhost:3000/112.jpg";
volume.children[2].children[0].children[0].modified();
r.render();
}
edit2: this is whats in my r.onShowtime = function() {}
volume.children[2].children[0].texture.file = 'http://localhost:3000/112.jpg';
volume.children[2].children[0].visible = true; // to activate the first layer
volume.children[2].children[0].modified();
console.log(volume.children[2].children[0].visible +" "+ volume.children[2].children[0].texture.file);
it outputs "true hostname/112.jpg"
when i inspect the .jpg in firebug the header is ok but the answer is "null"
when i inspect console.log(volume.children[2].children[0]); with firebug
.texture.file is set to hostname/112.jpg
when i go to "network" the .jpg has been transfered successfully
please notice that 112.jpg and level.jpg are the same. the first one is getting loaded in r.onShowtime and the other one is loaded at a keypressed event.
EDIT 3: volume.children[2].children[0] is of the type "X.slice", isn't it?
here is my approach: jsFiddle
and this is my actual issue and still not working: jsFiddle
Mhh..
I think a call to object.modified() is missing in the file setter (and in others setters from inject classes). Let's see when Haehn will come if he wants to change something internaly, but for the moment could you try to call it by yourself ?
You can try to add after the modification of texture :
volume.children[2].children[0].children[0].modified();
And if it doesn't work, in addition :
renderer.render();
Edit :
It's strange, I did a similar code and it did something. Can you please try something like that with opening your javascript console (Firefox, Chrome,... has one) and tell me the error you get ?
renderer.onShowtime = {
for (var i=0 ; i< volume.children[2].children.length ; i++) {
volume.children[2].children[i].texture.file="myimage.jpeg";
volume.children[2].children[i].modified();
}
}
It is important you call it in the onShowtime, because before the volume is not loaded, and so slicesX, slicesY... don't exist.
Edit2 :
Hey,
Thanks to the informations you added I think I've got the point ! In the render() method of our renderer3D there is a test on texture._dirty flag, that you cannot change from outside the framework. In addition the 1st rendering with a texture make that flag false, and loading a new texture doesn't seem to set that flag back to true in the current XTK. So, I think, we have to add it in the loader.load(texture, object) method. I'll make an issue on Github and see what Haehn thinks of it !
