Issue with marking of checkboxes in the list of items - list

I have a Vue app: it is To Do List, where after adding some notes by clicking button Add Task we receive a list of items to do. On the front of each item we have button Delete and checkbox to have opportunity to mark it as done. The bug is when I for example mark one of the items in the list as checked and after that delete it-marker that it was checked goes to the other item which was not marked as checked initially. Can you please advice how it can be solved using Vue.js or any other option? Below is my code:
Vue.createApp({
data(){
return{
placeholder: 'Start typing',
inputvalue: '',
notes: []
}
},
mounted() {
this.notes = JSON.parse(localStorage.getItem('note')) || [];
},
watch: {
notes: {
handler: function() {
localStorage.setItem('note', JSON.stringify(this.notes));
},
deep: true
}
},
methods: {
addnewtask(){
if (this.inputvalue !== ''){
this.notes.push(this.inputvalue)
this.inputvalue=''
}
},
removetask(index){
if (confirm('Do you really want to delete?'))
this.notes.splice(index, 1)
}
}
}).mount(app)

The main issue in you code is, you don't store any information about which task is checked and which one is not.let's say you checked 3rd task and then delete it, the new 3rd item from the top will be auto checked as it has no information about the task so can't differentiate between the new and the deleted task.
This can be solved many way one easy solution is, in your notes array store two types of data. One title and one is isChecked then v-model the checked value in template.
Update your addnewtask() function like this,
addnewtask() {
if (this.inputvalue !== "") {
this.notes.push({
title: this.inputvalue,
isChecked: false,
});
this.inputvalue = "";
}
},
In html use a v-modal to add a two way data binding for the note.isChecked and update note like note.title since note is currently an object now.

Width transition tailwind CSS

I would like to show and slide an element from the left to the right of the page. To do so, I hide it by default. When a button is clicked, the ul element is displayed and its width goes from 0px to 100vw. I also added a transition on the width property of the ul element.
HTML:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="https://cdn.tailwindcss.com"></script>
</head>
<body>
<button id="click_me" class="inline-block border-2 p-6"> Click Me! </button>
<ul id="hidden_nav" class="hidden w-0 h-screen bg-red-50 mt-10 transition-[width] duration-1000">
<li> Item </li>
<li> Item </li>
</ul>
</body>
</html>
JS:
const btn = document.getElementById('click_me');
const navul = document.getElementById('hidden_nav');
btn.addEventListener('click', function(){
navul.classList.toggle('hidden');
navul.classList.toggle('w-0');
navul.classList.toggle('w-screen');
});
Codepen link:
https://codepen.io/Okumak/pen/qBVjwdY
Yet, I cannot see any transition going on and I don't get why.
It will never work with a hidden class. An alternative solution would be opacity.
const btn = document.getElementById('click_me');
const navul = document.getElementById('hidden_nav');
btn.addEventListener('click', function(){
navul.classList.toggle('opacity-0');
navul.classList.toggle('w-0');
navul.classList.toggle('w-screen');
});
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script src="https://cdn.tailwindcss.com"></script>

<body>
<button id="click_me" class="inline-block border-2 p-6"> Click Me! </button>
<ul id="hidden_nav" class="opacity-0 w-0 h-screen bg-red-50 mt-10 transition-[width] duration-1000">
<li> Item </li>
<li> Item </li>
</ul>

</html>
Just look after the height. It still takes up space when hidden, just in case you want to toggle it as well then you can do so.

Invalid query: SELECT_WITH_AND_WITHOUT_AGG in Google Query Language

I'm trying to create a piechart from a single column of data with the google visualization API by counting each value, but I keep getting the following error message:
Invalid query: SELECT_WITH_AND_WITHOUT_AGG: C
INFORMATION
My spreadsheet can be found here: https://docs.google.com/spreadsheets/d/1lmmpJs2Bz3EfQWExB4KXq_uJWoLlq1PMCahy6w4ipcE/edit#gid=942634171
What I want to do is create a pie chart that counts the unique values in the 'What neighborhood are you from' column and plot their relative proportions.
The column itself can be seen here:
So I'd like to take this one column and create a table from it that reads like this:
EXAMPLE TABLE
Corona 2
Sunnyside 3
Elmhurst 4
And so on. And then use the string/number combination to populate a pie chart.
With regular SQL you could do SELECT Column, COUNT(Column) GROUP BY Column, so I'm assuming something similar would work for GQL.
So far these are some of the queries I've tried:
QUERIES:
'SELECT COUNT(C) GROUP BY C'
'SELECT C, COUNT(C) GROUP BY C'
'SELECT C, COUNT(C) PIVOT C
But none of these have worked.
I also get this error message in my console:
ERROR MESSAGE:
Here's the script I'm using that pertains to my problem:

// Load the Visualization API and the controls package.
google.charts.load('current', {'packages':['corechart', 'controls']});

UPDATE
Ideally I'd prefer a solution that only relies on changing the query itself, as this is syntactically cleaner. I'll be doing this several times throughout the project and would prefer to avoid workarounds that involve extra lines of code.
Any help would be greatly appreciated.
this should work, must be a bug or something...
'SELECT C, COUNT(C) GROUP BY C'
regardless, you can use data.visualization.data.group to manually aggregate the column
see following working snippet...
google.charts.load('current', {
callback: drawChart,
packages: ['controls', 'corechart', 'table']
});
function drawChart() {
var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1lmmpJs2Bz3EfQWExB4KXq_uJWoLlq1PMCahy6w4ipcE/gviz/tq?gid=942634171');
query.setQuery('SELECT C');
query.send(function (response) {
if (response.isError()) {
alert('Error: ' + response.getMessage() + ' - ' + response.getDetailedMessage());
return;
}
var dataGroup = google.visualization.data.group(
response.getDataTable(),
[0],
[{
aggregation: google.visualization.data.count,
column: 0,
label: response.getDataTable().getColumnLabel(0),
type: 'number'
}]
);
var neighborhoodChart = new google.visualization.ChartWrapper({
chartType: 'PieChart',
containerId: 'chart_div',
dataTable: dataGroup,
options: {
height: 240,
title: 'Neighborhood of Residence'
}
});
neighborhoodChart.draw();
});

} catch (curl::curl_easy_exception error) {
// If you want to get the entire error stack we can do:

}
std::regex pattern("alue=\"\\w{40}");
const char* responseArray = response.str().c_str();
std::cout << response.str();
std::smatch match;

When I run this code I always get the "Did not find the proper value!" output. But if I run the same regex through regexr I have no issues at all and it manages to find one match.
The match I am looking for in this case is:
alue="d2edcaa6bcc0fb19bf299b381212f59a194b8884
What am I doing wrong here?
const char* responseArray = response.str().c_str(); — binds responseArray to temporary value. String returned by str() is destroyed after this expression.
Better solution will save results in std::string and use it:
std::string responseArray = response.str();
std::cout << responseArray;
std::smatch match;
if(std::regex_search(responseArray, pattern)){
std::cout << "Found the proper value!" << std::endl;
} else {
std::cout << "Did not find the proper value" << std::endl;
}

how to reload a list WinJS

I want to create a list which dinamically grows after an event (take a shoot) I mean adding each picture on real time to the list, this is my method...
//Invoke the camera capture UI for snapping a photo
function imageCapture() {
...
//Creates the array, datalist and the namespace for making this data public
if (dataArray == null) { dataArray = new Array(); }
dataArray[captureCount] = { title: capturedItem.name, id: "img" + captureCount, picture: photoBlobUrl };
var dataList = new WinJS.Binding.List(dataArray);
var publicMembers = { itemList: dataList };
WinJS.Namespace.define("DataExample", publicMembers);
}
And this is the HTML page which loads the content
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta charset="utf-8" />
<title>eCamera</title>
<!-- Referencias de WinJS -->
<link href="//Microsoft.WinJS.1.0/css/ui-dark.css" rel="stylesheet" />
<script src="//Microsoft.WinJS.1.0/js/base.js"></script>

<!-- Referencias de eCamera2 -->
<link href="/css/default.css" rel="stylesheet" />
<script src="/js/default.js"></script>
</head>
<body >
<div id="content">
<div id="mediumListIconTextTemplate" data-win-control="WinJS.Binding.Template">
<div style="width: 150px; height: 100px;">
<!-- Displays the "picture" field. -->
<img src="#" style="width: 60px; height: 60px;" data-win-bind="alt: title; src: picture" />
<div>
<!-- Displays the "title" field. -->
<h4 data-win-bind="innerText: title"></h4>
<!-- Displays the "id" field. -->
<h6 data-win-bind="innerText: id"></h6>
</div>
</div>
</div>
<div id="basicListView"
data-win-control="WinJS.UI.ListView"
data-win-options="{ itemDataSource : DataExample.itemList.dataSource,
itemTemplate: select('#mediumListIconTextTemplate'),
itemsDraggable: true,
itemsReorderable: true }"></div>
</div>
</body>
</html>
If I load all the content in a fixed dataArray at first it works perfect, but dinamically adding elements and setting it all each time I take a picture so far doesn't work, how to make it work???
thanks in advance for the support
The app should not create new list each time. Use the WinJS.Binding.List.push method to append or splice can be used to insert. Since the list is observable, UI will autoupdate on changes (delete/add) to the list.
