I am new to using vuejs and js lets say I have an array
[0, 2, 10, 13.5, 20, 30, 10, 10]
I want to be able to get their percentage increase. So in this example I should get an array like this:
[400%, 35%, 48.1481%, 50%, -66.6667%, 0%]
How do I get this result? I saw some solutions like:
Get percentage value from difference between two arrays javascript
But in that example there are two arrays, in mine I only have one array
I have a array as follows:
data = [
{
"id":1
"name":"london"
},
{
"id":2
"name":"paris"
},
{
"id":3
"name":"london"
},
{
"id":4
"name":"paris"
},
{
"id":5
"name":"australia"
},
{
"id":6
"name":"newzearland"
}
]
At runtime this array can have n number of elements. I want to group this array with respect to name attribute. All the elements with same name should be moved to a separate array. I don’t know the what value can name have in advance. This is coming at runtime. For example, from above array I want final output as follows:
output:
newArray1 = [
{
"id":1
"name":"london"
},
{
"id":3
"name":"london"
}
]
newArray2 = [
{
"id":2
"name":"paris"
},
{
"id":4
"name":"paris"
}
]
newArray3 = [
{
"id":5
"name":"australia"
}
]
newArray4 = [
{
"id":6
"name":"newzearland"
}
]
How can I do that?
I have a Vue 3 Single File Component which houses a canvas element. I am using the fabric npm package. If I initialize the fabric canvas in the mounted hook using
data: function () {
return {
canvas: null,
}
},
mounted: function () {
const canvasElement = vm.$refs['canvas']
const canvas = new fabric.Canvas(canvasElement)
}
The canvas works fine and I am able to resize components, edit text objects etc.
But when I add this line:
this.canvas = canvas
then all objects on the canvas lose their editable and resizable nature. (Double click on text doesn’t work, the corners don’t allow resizing when using the cursor). Has anyone else experienced this? Is there a known solution?
Below I have script js and form.
$(document).on('submit','#form_create_user',function(e){
e.preventDefault();
var fd = new FormData(this);
var obj = $(this);
fd.append('course_id', "<?php echo $this->uri->segment(4); ?>");
obj.find('input[type="submit"]').val("Creating...")
$.ajax({
url: $(this).attr("action"),
data: fd,
cache: false,
processData: false,
contentType: false,
type: 'POST',
success: function (dataofconfirm) {
// do something with the result
// obj.find('input[type="submit"]').val("Confirm")
}
});
$.ajax({
url: "<?php echo site_url('home/saveValues/'); ?>",
data: fd,
cache: false,
processData: false,
contentType: false,
type: 'POST',
success: function (dataofconfirm) {
// do something with the result
toastr.success("Success created user.");
obj.find('input[type="submit"]').val("Confirm")
}
});
})<form action="?" method="post" name="form_create_user" id="form_create_user">
<input name="username" type="text" id="username" value="test"><input type="submit" name="Submit" value="Confirm">
</form>When I click on submit form then this script change text on button from “create” to “creating…” and display success action. But now this take about 1sec.
I need extand this script and I need:
display “creating…” for one minute and then return a success action.
note: the script run by form I need to set to run immediately, but only return success after a minute and reload the page.
Can anyone help me?
Background
I have a web3 dapp that is currently minting NFT’s correctly without issue.
When I call this mintNFT function, it sends a single transaction and succeeds each time.
I am adding functionality to “merge” two NFT’s using a contract function.
When I tie this new mergeTwoNFT to a button click, it seems to run the function multiple times as I get a metamask request for multiple transactions at once, sometimes 10-20 transactions to accept/reject at one time.
The first of these transactions will succeed however of course the remainder will fail because the tokenID 1/2 variables that we are merging are no longer owned by this user.
Request
I’m stuck on this sending multiple transactions. If I change the function call to be automatically run when the user “checks” two images they own, instead of using a button click event, it seems to work better without duplicate transactions but I don’t want this function to be called automatically upon two images being selected in case they’d like to undo it.
Code
This is my merge function. I have the same function for minting which works.
In the below example, alts is referencing the “checked” images on the UI that the user has selected.
async function mergeNFTs() {
const alts = $("#NFTGallery2 > li > input:checked + label img").map(function() {
return this.alt
}).get();
var nftChosen1 = alts[0]
var nftChosen2 = alts[1]
setFeedback(`Merging your ${nftChosen1} and ${nftChosen2}...`);
setClaimingNft(true);
dispatch(fetchData(blockchain.account));
myContract.methods
.mergeTwoNFT(nftChosen1, nftChosen2)
.send({
from: blockchain.account
})
.once('error', (err) => {
console.log(err);
setFeedback(
"Sorry, something went wrong when Merging your NFT's please try again later."
);
setClaimingNft(false);
})
.then((receipt) => {
var tokenId = receipt.events.Transfer[2].returnValues.tokenId;
console.log(
'Your new NFT ID is: ' + receipt.events.Transfer[2].returnValues.tokenId
);
setFeedback(
`WOW, the ${CONFIG.NFT_NAME} #${tokenId} is yours!`
);
myContract.methods
.tokenURI(tokenId)
.call()
.then(function (res) {
$.getJSON(res, function (data) {
const mintedNFTImage = `
<div class="layeredImg "sc-gKseQn gTjrPu" id="mintedImage">
<img id="imgbg" src="${data.image}"/>
</div>
<br>
`;
document.getElementById('NFTEmbed').innerHTML = mintedNFTImage;
});
})
.catch(function (err) {
console.log(err);
});
setClaimingNft(false);
dispatch(fetchData(blockchain.account));
getData();
getData2();
});
};<button id="mergingButton" onclick=mergeNFTs() class="">MERGE</button>I would like a grease/tamper monkey script, that when I visit a page, it looks for the following HTML on the page, and if it is present alert.

I have image elements in my DOM that use blob URL in their src attribute.
Think like this:
<img class="full-media opacity-transition slow open shown" width="432"
height="432" alt="" draggable="true"
src="blob:https://web.telegram.org/1c037f99-5201-45de-937c-548da5706021">
What I want is to be able to do some ocr on this image , however fetching the full url or even without the blob gives me a 404. How can I get the image either as a file or any acceptable format for tesseract.recognize?

Is it possible to field an imput file automaticaly.
I try by myself but i’m no enough good find a solution to do it.
I can’t do it in the console like if i do it manualy.
I think JS is the way to do it, each time the same file in the same input…
Same code as this exemple :
