I wrote a function for a big commerce store.
On their category page, there are multiple products, I need a way to track the clicks of products and add them to the cart.
This is for the add to cart->
document.querySelectorAll('a[data-button-type=\"add-cart\"]', 'data-addtocart').forEach((element, i) => {
element.addEventListener('click', (e) =>{
const article = e.target.closest('article');
const articleArray = article.getAttribute('data-test').split('-');
const productName = article.querySelector('.card-title').getElementsByTagName('a')[0].getAttribute('aria-label');
const itemTitle = productName.split(', ');
const data = {
id : articleArray[1],
name : itemTitle[0],
brutto : Number(itemTitle[1].replace(/[^0-9\\.-]+/g,\"\")),
netto : Number(itemTitle[1].replace(/[^0-9\\.-]+/g,\"\")),
quantitiy : 1,
position : i + 1
};
});
This is for the product list ->
let productPosition=1;
{{#each category.products}}
document.querySelector(\"[data-test='card-{{id}}']\").addEventListener(\"click\", (e) => {
_jts.push({
track:'product',
type:'productlistclick',
id:'{{id}}',
name:'{{name}}',
position:productPosition++
});
});
{{/each}}
If I click the add to cart button it tracks both the product list and adds to cart. Any way to avoid the product list click if I click the add to cart button?
Why when you are searching for something else is deleting the previous contents ?For example first you search for egg and show the contents but then when you search for beef the program deletes the egg and shows only beef.Code :
const searchBtn = document.getElementById('search-btn');
const mealList = document.getElementById('meal');
const mealDetailsContent = document.querySelector('.meal-details-content');
const recipeCloseBtn = document.getElementById('recipe-close-btn');
// event listeners
searchBtn.addEventListener('click', getMealList);
mealList.addEventListener('click', getMealRecipe);
recipeCloseBtn.addEventListener('click', () => {
mealDetailsContent.parentElement.classList.remove('showRecipe');
});
// get meal list that matches with the ingredients
function getMealList(){
let searchInputTxt = document.getElementById('search-input').value.trim();
fetch(`https://www.themealdb.com/api/json/v1/1/filter.php?i=${searchInputTxt}`)
.then(response => response.json())
.then(data => {
let html = "";
if(data.meals){
data.meals.forEach(meal => {
html += `
<div class = "meal-item" data-id = "${meal.idMeal}">
<div class = "meal-img">
<img src = "${meal.strMealThumb}" alt = "food">
</div>
<div class = "meal-name">
<h3>${meal.strMeal}</h3>
Get Recipe
</div>
</div>
`;
});
mealList.classList.remove('notFound');
} else{
html = "Sorry, we didn't find any meal!";
mealList.classList.add('notFound');
}
mealList.innerHTML = html;
});
}
It's because you are replacing the contents in the mealList element every time.
A simple workaround would be to retrieve the the innerHTML values before you update it.
Something like
let html = mealList.innerHTML;
rather than starting off empty every time you call the function should do the trick.
I have coded a ajax based "JS TABS" containing .JSON file like 10 months ago, now wanted to reuse it, and can't find out why it's not working. I haven't touched it since and don't know where is the bug.
When i click the button to render products nothing prints out - except console telling me: items is undefined = so i moved it inside function changeCategoryItems(categoryId) { } well no errors but nothing renders...can someone help me ?
Here is a codepen reference of what i mean: https://codepen.io/Contemplator191/pen/WNwgypY
And this is JSON : https://api.jsonbin.io/b/5f634e0c302a837e95680846
If codepen is not suitable/allowed here is whole JS for that
let items = [];
const buttons = document.querySelectorAll('button');
const wrapper = document.querySelector('section.products');
buttons.forEach(function (button) {
button.addEventListener('click',event => {
changeCategoryItems(event.target.dataset.category);
});
});
function changeCategoryItems(categoryId) {
let items = [];
const buttons = document.querySelectorAll('button');
const wrapper = document.querySelector('section.products');
const viewItems = (categoryId == 0 ) ? items : items.filter(item => item.category == categoryId);
wrapper.innerHTML = "";
viewItems.forEach(item => {
const div = document.createElement('div');
div.setAttribute("class", "product");
div.innerHTML = createItem(item);
wrapper.appendChild(div);
});
};
function createItem(item) {
return `
<div class="product__img">
<img src="${item.img}" class="">
</div>
<div class="product__name _tc">
<h4 class="">${item.heading}</h4>
</div>
<div class="text-desc product__desc">
<p class="">${item.description}</p>
</div>
<div class="product__bottom-content">
<span class="product__info">${item.info}</span>
${item.btn}
</div>
`
}
fetch('https://api.jsonbin.io/b/5f634e0c302a837e95680846')
.then(function (res) { return res.json() })
.then(function (data) {
items = data.items;
changeCategoryItems(1);
});`
In your fetch you're trying to assign data.items to the items variable but the api doesn't return data with an items node so items is undefined. It's possible the api changed their return format since the last time you used it which would explain why it worked previously.
this seems to fix it
.then(function (data) {
items = data;
changeCategoryItems(1);
});
Your issue is in this line:
items = data.items;
Now, the returned value is an array, hence you can use it as it is.
The updated codepen
I have created a product card view in Laravel. the card has a simple "accordion" ('Show Details') - closed by default - that is managed by Vue.js as well as a Vue.js quantity counter that changes the weight value in grams if you add products. It all functions very well on the card's view and it looks like this (closed):
I have another view in which I query my DB for product names with Vue.js to display all products of the same name as a result. The problem is when the cards are displayed on that "parent" view, they all appear with the accordion open and the counter is not responsive. It looks like so:
As you can see, the tailwindcss code is rendered without a problem but the Vue.js is being completely ignored (Although the parent view's Vue.js functions work perfectly) What am I doing wrong? What am I missing here? Why are the directives inside the included blade being ignored?
Here is the Vue.js method that manages the (product cards) views integration onto the parent (product name search) view:
setGearItem(gearItem) {
this.gearItem = gearItem;
this.modal = false;
console.log(gearItem);
document.getElementById("displaySearch").innerHTML = "";
axios.get('/send-name-get-ids/' + this.gearItem)
.then((response) => {
console.log(response.data);
if (response.data.length === 0) {
document.getElementById("displaySearch").innerHTML = `"<strong>${gearItem}</strong>" was not found in our database. You can add it manually:`;
this.generalForm = true;
return;
} else {
for (let i = 0; i < response.data.length; i++) {
axios.get('/gearitem/' + response.data[i])
.then((response) => {
console.log(response.data);
document.getElementById("displaySearch").innerHTML += response.data;
this.generalForm = false;
})
.catch((error) => {
document.getElementById("displaySearch").innerHTML =
"No items to display";
console.log(error);
});
}
}
});
},
The problem is in the .innerHTML method as Vue.js ignores anything added via this method even if it's an AJAX. The solution consists on changing the controller to return a JSON and not a blade view, then using the JSON to populate a Vue.js component to create the item's card. the setGearItem() method was changed like so:
setGearItem(gearItem) {
this.gearItem = gearItem;
this.modal = false;
console.log(gearItem);
document.getElementById("displaySearch").innerHTML = "";
this.displayItemCard = false;
axios.get('/send-name-get-ids/' + this.gearItem)
.then((response) => {
console.log(response.data);
this.gearItemId = response.data[0];
if (response.data.length === 0) {
document.getElementById("displaySearch").innerHTML =
`<p class="text-gray-700 ">
<strong class="capitalize">${gearItem}</strong>
was not found on our database. <br>You're free to add it manually! </p>`;
this.generalForm = true;
return;
} else {
this.displayItemCard = true;
}
});
},
the displayItemCard just activates the card component on the view and displays the correct card according to the id.
So I am trying to make a flashcards website, where users can add, edit, and delete flashcards. There are two cards - front and back. The user can already add words, but cannot edit or delete them. For the purposes of this question I will use an example array:
var flashcards = [["Uomo", "Man"],["Donna", "Woman"],["Ragazzo", "Boy"]]
But I would like a more user-friendly way to edit the flashcards, preferably using a table like this:
<table>
<tr>
<th>Front</th>
<th>Back</th>
</tr>
<tr>
<td><input type="text" name="flashcard" value="Uomo"> </td>
<td><input type="text" name="flashcard" value="Man"></td>
</tr>
<tr>
<td><input type="text" name="flashcard" value="Donna"></td>
<td><input type="text" name="flashcard" value="Woman"></td>
</tr>
<tr>
<td><input type="text" name="flashcard" value="Ragazzo"></td>
<td><input type="text" name="flashcard" value="Boy"></td>
</tr>
</table>
<button type="button">Add more</button>
<br>
<button type="button">Save changes</button>
So they can update their flashcards editing the input fields, or clicking "add more" and it creating a new row. Clicking "save changes" updates the array to the content of the table.
I don't mind it not being a HTML table per se, but something that is easy to edit for the user.
I just cannot figure out the best way to approach this. Any advice?
I already recommended VueJS - it really is a pretty good tool for this problem. Regardless, I have typed up a basic solution using vanilla JavaScript. For the editing part it uses the contenteditable HTML attribute which allows the end-user to double click an element and change it's textContent.
The html display is basic so you can change it however to fit your needs
<div id=style="width: 100%;">
<ul id="table" style="list-style-type: none; display: inline-block;">
</ul>
</div>
<script>
var flashcards = [["Uomo", "Man"],["Donna", "Woman"],["Ragazzo", "Boy"]];
var displayedCard = []; //Using a parallel array to keep track of which side is shown
for(var i = 0; i < flashcards.length; i++){
displayedCard.push(0);
}
function renderFlashcardTable(){ //This will do the initial rendering of the table
let ulTable = document.getElementById("table");
for(var i = 0; i < flashcards.length; i++){
let card = flashcards[i];
let indexOfSideShown = displayedCard[i];
let li = document.createElement("li");
let cardValueSpan = document.createElement("span");
cardValueSpan.innerHTML = card[indexOfSideShown]; //Get the value of the side of the card that is shown
cardValueSpan.setAttribute("contenteditable", "true");
cardValueSpan.oninput = function(e){ //This method gets called when the user de-selects the element they have been editing
let li = this.parentElement;
let sideIndex = parseInt(li.getAttribute("side-index"));
card[sideIndex] = this.textContent;
}
li.appendChild(cardValueSpan);
li.appendChild(getFlipSidesButton(li));
li.setAttribute("side-index", indexOfSideShown);
li.setAttribute("card-index", i);
ulTable.appendChild(li);
}
}
function getFlipSidesButton(listItem){//This is generated for each card and when clicked it "flips the switch"
let btn = document.createElement("button");
btn.innerHTML = "Flip card";
btn.onclick = function(e){
let card = flashcards[listItem.getAttribute("card-index")];
let index = parseInt(listItem.getAttribute("side-index"));
let nextSide = (index == 1) ? 0 : 1;
listItem.setAttribute("side-index", nextSide);
listItem.children[0].innerHTML = card[nextSide];
}
return btn;
}
renderFlashcardTable();
</script>
I've put together a working sample using pure native javascript with a data-driven approach. You can have a look and understand the way how data should be manipulated and worked with in large Js application.
The point here is to isolate the data and logic as much as possible.
Hope this help.

i think you can use In-Place Editing System and there's a good tutorial i found
