I have a parent component where I am doing the API call and getting the response. So what I am trying to do is pass this response as a prop to child component in Vue. So here is my parent component and the call:
<button class="btn button col-2" @click="addToCart()">
Add to cart
</button>
addToCart: function () {
let amount = this.itemsCount !== "" ? this.itemsCount : 1;
if(this.variationId != null) {
this.warningMessage = false;
cartHelper.addToCart(this.product.id, this.variationId, amount, (response) => {
this.cartItems = response.data.attributes.items;
});
} else {
this.warningMessage = true;
}
},
So I want to pass this "this.cartItems" to the child component which is:
<template>
<div
class="dropdown-menu cart"
aria-labelledby="triggerId"
>
<div class="inner-cart">
<div v-for="item in cart" :key="item.product.id">
<div class="cart-items">
<div>
<strong>{{ item.product.name }}</strong>
<br/> {{ item.quantity }} x $45
</div>
<div>
<a class="remove" @click.prevent="removeProductFromCart(item.product)">Remove</a>
</div>
</div>
</div>
<hr/>
<div class="cart-items-total">
<span>Total: {{cartTotalPrice}}</span>
<a href="#" @click.prevent="clearCartItems()">Clear Cart</a>
</div>
<hr/>
<router-link :to="{name: 'order'}" class="btn button-secondary">Go To Cart</router-link>
</div>
</div>
</template>
<script>
export default {
computed: {
},
methods: {
}
};
</script>
So I am quite new in vue if you can help me with thi, I would be really glad.
Vue.component('Child', {
template: `
<div class="">
<p>{{ childitems }}</p>
</div>
`,
props: ['childitems']
})
new Vue({
el: '#demo',
data() {
return {
items: []
}
},
methods: {
getItems() {
//your API call
setTimeout(() => {
this.items = [1, 2]
}, 2000);
}
}
})
Vue.config.productionTip = false
Vue.config.devtools = false<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<button @click="getItems">get data</button>
<Child v-if="items.length" :childitems="items" />
</div>You can wait for response, and when you gate this.cartItems then render your child component with a v-if="this.cartItems.length" condition
Passing props is quite simple. If cartItems is what you wan´t to pass as a prop, you can do this:
<my-child-component :cartItems="cartItems"></my-child-component>
In this case you implemented your child as myChildComponent. You pass cartItems with :cartItems="cartItems" to it. In your child you do this:
props: {
cartItems: Object
}
Now you can use it with this.cartItems in your methods or {{cartItems}} in your themplate.
