如何将布尔道具传递给vuejs中的另一个组件

Question

I have two components: component A and Component B. In the component A, I have a props called hasBorder with Boolean type and when i call component A in the component B, I passed value to a props component of component A, I have an error.

html component A:

<div> <img src="path" :style="hasBorder ? 'border:5px;': ''"/></div>

js component A:

Vue.component('compA', {
    props: {
       hasBorder:{
         type:Boolean,
         default:false
       }
    }
});

html component B:

<div> My image : <compA has-border="myStyle"></compA></div>

js component B:

Vue.component('compB', {
    data: {
       return {
           myStyle : { type:Boolean, default :true}
        } 
    }
});

I have this error "Invalid prop:type check failed for prop hasBorder . Expected Boolean, got String with value "myStyle".

How can i fix this error please

Answer 1

You expect bool value but you are trying to send an object.

Try this

 Vue.component('compB', { data: { return { myStyle : true } } });

And use v-bind

 <div> My image : <compA v-bind:has-border="myStyle"></compA></div>

Answer 2

You need to bind your props with v-bind: or : in order to pass data. Data property needs to be a function that returns object. Please take a look at snippet:

 const app = Vue.createApp({ data() { return { myStyle: true, myPath: 'https://picsum.photos/100' }; }, }) app.component('compA', { template: ` <div><img :src="path" :style="hasBorder ? 'border: 5px solid turquoise;': ''"/></div> `, props: { hasBorder:{ type:Boolean, default:false }, path: { type: String, default: '' } } }) app.mount('#demo')

 <script src="https://unpkg.com/vue@3/dist/vue.global.prod.js"></script> <div id="demo"> <div> My image : <comp-a :has-border="myStyle" :path="myPath"></comp-a></div> </div>
