I've encountered a frustrating problem with Vue JS >.<. My methods are being triggered unexpectedly. I have a button that is supposed to execute a specific method, but this method gets executed along with other methods, causing annoyance...
Here is my form
<form class="row">
<div class="col-xl-6 col-lg-6 col-md-6 col-sm-12 col-12 pr-xl-0 pr-lg-0 pr-md-0 m-b-30">
<div class="product-slider">
<img class="d-block" :src="image" alt="First slide" width="285" height="313">
Image URL <input type="text" @focusout="showPicture" id="imageLink">
</div>
</div>
<div class="col-xl-6 col-lg-6 col-md-6 col-sm-12 col-12 pl-xl-0 pl-lg-0 pl-md-0 border-left m-b-30">
<div class="product-details">
<div class="border-bottom pb-3 mb-3">
<h2 class="mb-3">
<input type="text" value="Product Name" minlength="4" id="name" required/>
</h2>
<h3 class="mb-0 text-primary">$<input type="number" value="1.00" step="0.01" id="price" required></h3>
</div>
<div class="product-size border-bottom">
<h4>Provider</h4>
<input type="text" value="Pro Inc." minlength="3" id="provider" required>
<div class="product-qty">
<h4>Quantity</h4>
<div class="quantity">
<input type="number" value="1" id="quantity" required>
</div>
</div>
</div>
<div class="product-description">
<h4 class="mb-1">Description</h4>
<textarea rows="4" cols="50" minlength="50" id="description" required>Sample Text</textarea>
<button :onclick="addProduct()" class="btn btn-primary btn-block btn-lg">Add to inventory</button>
</div>
</div>
</div>
</form>
and here's the complete script.
<script>
const DB_NAME = 'DBInventory';
const DB_VERSION = 1;
export default {
data: function() {
return {
db:null,
ready:false,
addDisabled:false,
image: "https://i.imgur.com/O9oZoje.png",
};
},
async created() {
this.db = await this.getDb();
this.ready = true;
},
methods: {
showPicture() {
let link = document.getElementById("imageLink").value;
if(link !== "")
this.image = link;
},
async getDb() {
return new Promise((resolve, reject) => {
let request = window.indexedDB.open(DB_NAME, DB_VERSION);
request.onerror = e => {
console.log('Error opening db', e);
reject('Error');
};
request.onsuccess = e => {
resolve(e.target.result);
};
request.onupgradeneeded = e => {
console.log('onupgradeneeded');
let db = e.target.result;
let objectStore = db.createObjectStore("products", { autoIncrement: true, keyPath:'id' });
console.log(objectStore);
};
});
},
async addProduct() {
this.addDisabled = true;
let product = {
name: document.getElementById("name").value,
provider: document.getElementById("provider").value,
price: document.getElementById("price").value,
quantity: document.getElementById("quantity").value,
description: document.getElementById("description").value,
image: document.getElementById("imageLink").value,
};
console.log('about to add '+JSON.stringify(product));
await this.addProductToDb(product);
this.addDisabled = false;
},
async addProductToDb(product) {
return new Promise((resolve, reject) => {
//delete me
console.log(reject);
let trans = this.db.transaction(['products'],'readwrite');
trans.oncomplete = e => {
//delete me
console.log(e);
resolve();
};
let store = trans.objectStore('products');
store.add(product);
});
},
}
}
</script>
One of my methods triggers even when I'm not focused on the image input field. It does work, but it also triggers the addProduct(), which adds my item to the indexDB, something I only want to happen when I click the "Add to inventory" button.
This situation is quite confusing for me as I'm still learning Vue JS ^^' (I'm using Vue 3)
