I am currently utilizing Vue.js version 3 and below is the code snippet:
<template>
<h5>List of Products</h5>
<h3>Filter</h3>
<button v-on:click="resetOptions">Reset</button>
<button v-on:click="sorting">Sorting</button>
<button v-on:click="sorting2">Sorting2</button>
<select v-model="category">
<option value="Accessories">Accessories</option>
<option value="Laptop">Laptop</option>
<option value="Stationary">Stationary</option>
</select>
<div>
<input type="checkbox" name="test" id="test" v-model="city" value='Roma' />
<label for="test"> Roma</label>
<input type="checkbox" name="test2" id="test2" v-model.trim="city" value='Barselona' />
<label for="test2"> Barselona</label>
<input type="checkbox" name="test3" id="test3" v-model.trim="city" value='Milano' />
<label for="test3"> Milano</label>
</div>
<input type="text" v-model="name" placeholder="Filter By Name"/>
<label for="vol">Price (between 0 and 1000):</label>
<input type="range" v-model.trim="range" min="0" max="1000" step="10"/>
<ul>
<li v-for="product in filterProducts" :key="product.price"> Product Name : {{product.name}} - Price : {{product.price}} ({{product.category}})
{{product.city}}
</li>
</ul>
</template>
<script>
window.axios = require("axios");
export default {
data: ()=> ({
city:['Barselona', 'Milano' , 'Roma'],
category: '',
name: '',
range: '10000',
products: [] ,
}),
mounted(){
axios.get('http://localhost:3000/products')
.then(response =>this.products = response.data);
},
computed: {
filterProducts: function(){
return this.filterProductsByName(this.filterProductsByRange(this.filterProductsByCity(this.filterProductsByCategory(this.products))))
},
},
methods: {
filterProductsByCategory: function(products){
return products.filter(product => !product.category.indexOf(this.category))
},
filterProductsByName: function(products) {
return products.filter(product => !product.name.toLowerCase().indexOf(this.name.toLowerCase()))
},
filterProductsByCity: function(products) {
return products.filter(product => this.city.indexOf(product.city) !== -1)
},
filterProductsByRange: function(products){
return products.filter(product => (product.price >= 0 && product.price <= this.range) ? product : '')
},
sorting:function(){
this.products.sort((a,b)=>(a.price > b.price) ? 1 : -1)
},
sorting2:function(){
this.products.sort((a,b)=>(a.price < b.price) ? 1 : -1)
},
uniqueCheck(e){
this.city = [];
if (e.target.checked) {
this.city.push(e.target.value);
}
},
resetOptions:function(){
this.category='',
this.city='',
this.name='',
this.range='1000'
},
},
}
</script>
<style>
</style>
Currently, my API data is displayed by default due to pre-filled values in the city array. However, I would like my checkboxes to be unchecked by default and display all data initially. Upon checking a checkbox, I want to filter my data accordingly. How can I achieve this?
