Is there an option in DOJO where files can be uploaded by Drag and Drop from desktop to the browser?
No I dont believe so. As outlined here and here its not really possible to do without using a plugin.
Old post, but still one of those posts being found by google easily. For those interested how to do this:
Have a look at this SO answer
Dojo overview of how to use its Uploader (styled as a button)
Use addDropTarget to link a dropArea for that uploader (for HTML5-enabled browsers -- see also first link))
To make the drop target visibly react to drag events, I had to connect directly to browser events like ondragenter or ondragleave (see code snippet below)
createUploader: function() {
// ... define uploader and droptarget
d_on(this.dropArea, "dragover", d_lang.hitch(this, this.dropAreaOver));
d_on(this.dropArea, "dragleave", d_lang.hitch(this, this.dropAreaLeave));
d_on(this.dropArea, "drop", d_lang.hitch(this, this.dropAreaLeave));
}
dropAreaOver: function(evt) {
evt.preventDefault();
domClass.add(this.dropArea, "dropAreaOver");
},
dropAreaLeave: function(evt) {
evt.preventDefault();
domClass.remove(this.dropArea, "dropAreaOver");
}

I use the dynamic source for vue-webpack images in nuxt :src="require('path/to/image' + dynamic.variable)" in my project navbar. If the users substitute their image through a form which refetches their information and deletes their previous image I get a webpack error module (img) not found (it does not find the new one): is there a way to solve this, like wait for webpack HRM to finish?
I tried setting up a setTimeout() of one second before user re-fetch and it works, but I don't like a random waiting, I'd use a promise or a sync dynamic, the point is webpack hot reload is not controlled by my functions.. I also tried with setting the dynamic path as a computed: but it doesn't fix.
My image tag:
<img v-if="this.$auth.user.image" class="userlogo m-2 rounded-circle" :src="require('#assets/images/users/' + this.$auth.user.image)" alt="usrimg">
My Useredit page methods:
...
methods: {
userEdit() {
//uploads the image
if (this.formImageFilename.name) {
let formImageData = new FormData()
formImageData.append('file', this.formImageFilename)
axios.post('/db/userimage', formImageData, { headers: { 'Content-Type': 'multipart/form-data' } })
// once it has uploaded the new image, it deletes the old one
.then(res=>{this.deleteOldImage()})
.catch(err=>{console.log(err)})
}else{
this.userUpdate() //if no new image has to be inserted, it proceeds to update the user information
}
},
deleteOldImage(){
if(this.$auth.user.image){axios.delete('/db/userimage', {data: {delimage: this.$auth.user.image}} )}
console.log(this.$auth.user.image + ' deleted')
this.userUpdate() // it has deleted the old image so it proceeds to update the user information
},
userUpdate(){
axios.put(
'/db/user', {
id: this.id,
name: this.formName,
surname: this.formSurname,
email: this.formEmail,
password: this.formPassword,
image: this.formImageFilename.name,
})
.then(() => { console.log('User updated'); this.userReload()}) // reloads the updated user information
.catch(err => {console.log(err)} )
},
userReload(){
console.log('User reloading..')
this.$auth.fetchUser()
.then(() => { console.log('User reloaded')})
.catch(err => {console.log(err)} )
},
}
...
the problem happens after "console.log('User reloading..')" and before "console.log('User reloaded');", it is not related to the file upload nor the server response. I broke a single function in many little ones just to check the function progression and its asynchronous dynamics but the only one that is not manageable is the webpack hot reload :/
I'd like the users to upload their images and see their logo in the Navbar appear updated after submitting the form.
First of all, as somebody told you in the comments, webpack hmr shouldn't be used for production.
In Nuxt, everything that you reference from the assets folder will be optimized and bundled into the project package. So the ideal use case for this folder is all assets that can be packaged and optimized, and most likely won't change like fonts, css, background images, icons, etc.
Then, require is called only once by webpack when it is either building the site for local development or building the site for generating a production package. The problem in your case is that you delete the original file while you're in development and webpack tries to read it and fails.
In the case of these images that the user uploads, I think you should use the static folder instead and instead of using require you'll have to change the :src with
:src="'/images/users/' + this.$auth.user.image"
Let me know if this helps.
Okay, I probably solved it.
HMR: you are of course right. Thank you for pointing out, I am sorry, I am a beginner and I try to understand stuff along the way.
Aldarund, thank you, your idea of not changing the path and cache it client side.. I am too noob to understand how I could implement it ( :) ) but it gave me a good hint: the solution was to keep the image name as the user id + the '.png' extension and to manage the image with jimp so that the image name, extension and file type are always the same, and with or without webpack compiling the new path, I always have the correct require().
Jair, thank you for the help, I didn't follow that road, but I will keep it as a second chance if my way creates errors. Just to be specific: the error comes when it does not find -and asks for the name of- the NEW image, not the OLD one, as I wrote in my question: it happens because the fetchUser() functions reloads the user information including the new image name.
Do you guys see any future problems in my methodology?
Really thank you for your answers. I am learning alone and it's great to receive support.
I'm using a headless browser (phantomjs) in conjunction with Mink to do some functional testing on my Website.
Now in this setting, files can not be downloaded regularly e.g: by clicking a link. So I have to extract the url from the link or the button, and download the file manually.
As I just stated sometimes there is no link () for the download, but a button in a Form (e.g: Inputting data for a report in the form, and receiving the report file on submission).
So what I need to do is simulate clicking the link or button and extract the Data for the Request that would have been sent, and use that data to download the file manually.
Is there a way to do this?
Note: I'm using guzzle to actually download the file.
Mmmm... I don't know if you solved this and only as an alternative to typical mink methods. As Phantomjs is a javascript based browser engine, did you tried with javascript?
You could try something like this:
public function getElementHref($element)
{
/* #var FeatureContext $this */
$function = "(function(){
//Javascript method to get the href.
})()";
try {
return $this->featureContext->getSession()->evaluateScript($function);
} catch (Exception $e) {
throw new Exception('Element not found');
}
}
You can find a method to do this in javascript here: How to get anchor text/href on click using jQuery?
Then use the URL returned with file_get_contents (depending on the file type) and that's it.
I'm trying to automate an application that uses form security in order to upload a file and then scrape data from the returned HTML.
I started out using the solution from this question. I can define my steps and get through the entire workflow as long as the last step is rendering the page.
Here are the two steps that are the meat of my script:
function() {
page.open("https://remotesite.com/do/something", function(status) {
if ('success' === status) {
page.uploadFile('input[name=file]', 'x.csv');
page.evaluate(function() {
// assignButton is used to associate modules with an account
document.getElementById("assignButton").click();
});
}
});
},
function() {
page.render('upload-results.png');
page.evaluate(function() {
var results = document.getElementById("moduleProcessingReport");
console.log("results: " + results);
});
},
When I run the script, I see that the output render is correct. However, the evaluate part isn't working. I can confirm that my DOM selection is correct by running it in the Javascript console while on the remote site.
I have seen other questions, but they revolve around using setTimeout. Unfortunately, the step strategy from the original approach already has a timeout.
UPDATE
I tried a slightly different approach, using this post and got similar results. I believe that document uses an older PhantomJS API, so I used the 'onLoadFinished' event to drive between steps.
i recomend you use casperjs or if you use PJS's webPage.injectScript() you could load up jquery and then your own script to do form input/navigation.
I am looking fore some code allowing me to launch automatically a video after another one.
I'am using the great video.js library, which has a quite complete API. I found some snippet to get an event listener working at the end of the 1st video, but then I cannot launch the second one.
This is working, displaying an alert at the end of the 1st video :
_V_("intro").ready(function(){
this.addEvent("ended", function(){
alert('foo');
});
});
And this is also working, launching a video in fullscreen on page reload :
_V_("leader").ready(function(){
var leader = this;
leader.requestFullScreen();
leader.play();
});
But I can't get the 2nd video launching in fullscreen at the end of 1st video...
Last subtility, I would like to entirely build the 2nd video with javascript, not having to write it and just hiding id with CSS.
Thank you folks !
Elliot
You can simply use the provided 'src' method in the Video.js API, if you want to play a second video right after the first one finishes it would work like this:
_V_("intro").ready(function(){
this.addEvent("ended", function(){
this.src({ type: "video/mp4", src: "http://path/to/second/video.mp4" });
});
});
I've been able to send data from the background page to the content script. but this is done using sendrequest(). I will need to send data back and forth so I'm trying to figure out the correct syntax for using the port.postmessage from background page to content script. I have already read, several times, the google page on Messaging and I don't seem to get it. I even copied the code directly from the page and tested with no result. All I'm trying to do for now is send data from background page to content script using connect as opposed to sendrequest. The response from the content script I will deal with later as code with this response has been the main thorn. I just want to understand the process one step at a time without the extra knowledge of sending a response back.
I'm not sure if this contravenes the rules of this board but can someone PLEASE give me an example of some code to do this (background page and content script excerpt, the background page is the sender).
I've asked for assistance several times on this site only to be told to read the documentation or check out sites I've already visited.
If you just want any example of opening a port from the extension to a content script, here's the simplest I can think of. The background just opens a port and sends "Hello tab!" over the port, and the content script sends a message to the background any time you click on the webpage.
I think this is pretty simple, so I don't know why you are so stressed. Just make sure that the content tab is already listening when the background tries to connect (I do this by waiting until the "complete" event).
manifest.json:
{
"name": "TestExt",
"version": "0.1",
"background_page": "background.html",
"content_scripts": [{
"matches": ["http://localhost/*"], // same as background.html regexp
"js": ["injected.js"]
}],
"permissions": [
"tabs" // ability to inject js and listen to onUpdated
]
}
background.html:
<script>
var interestingTabs = {};
chrome.tabs.onUpdated.addListener(function(tabId, changeInfo, tab) {
// same as manifest.json wildcard
if (changeInfo.url && /http:\/\/localhost(:\d+)?\/(.|$)/.test(changeInfo.url)) {
interestingTabs[tabId] = true;
}
if (changeInfo.status === 'complete' && interestingTabs[tabId]) {
delete interestingTabs[tabId];
console.log('Trying to connect to tab ' + tabId);
var port = chrome.tabs.connect(tabId);
port.onMessage.addListener(function(m) {
console.log('received message from tab ' + tabId + ':');
console.log(m);
});
port.postMessage('Hello tab!');
}
});
</script>
injection.js:
chrome.extension.onConnect.addListener(function(port) {
console.log('Connected to content script!');
port.onMessage.addListener(function(m) {
console.log('Received message:');
console.log(m);
});
document.documentElement.addEventListener('click', function(e) {
port.postMessage('User clicked on a ' + e.target.tagName);
}, true);
});
