Question

i wanted to get the computed data and display in another component. However i put the computed in my app.vue and try to call this computed using :style="inputStyles" in my ChangeBackground.vue . But when i try to do this it showing error that " Property or method "inputStyles" is not defined on the instance but referenced during render" Can someone help me? Thank you
You can access the code here:
https://codesandbox.io/s/hardcore-morning-5ch1u?file=/src/components
Here is the code:
App.vue
<template>
<div id="app">
<ChangeBackground msg="Hello Vue in CodeSandbox!" />
</div>
</template>
<script>
import ChangeBackground from "./components/ChangeBackground";
export default {
name: "App",
components: {
ChangeBackground,
},
data() {
return {
bgColor: "red",
};
},
created() {
this.bgColor = "#F6780D";
},
computed: {
inputStyles() {
return {
background: this.bgColor,
};
},
},
};
</script>
<style>
#app {
font-family: "Avenir", Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
body {
background-color: blue;
}
</style>
ChangeBackground.vue
<template>
<div class="hello" :style="inputStyles">
<h1>{{ msg }}</h1>
</div>
</template>
<script>
export default {
name: "HelloWorld",
data() {
return {
msg: "Getting the computed area here to change the background",
};
},
};
</script>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<style>
h1,
h2 {
font-weight: bold;
}
ul {
list-style-type: none;
padding: 1rem;
}
li {
display: inline-block;
margin: 0 10px;
}
a {
color: #42b983;
}
</style>

You should pass it as prop as you did with msg :
App.vue
<ChangeBackground msg="Hello Vue in CodeSandbox!" :input-styles="inputStyles" />
ChangeBackground.vue
<template>
<div class="hello" :style="inputStyles">
<h1>{{ msg }}</h1>
</div>
</template>
<script>
export default {
name: "HelloWorld",
props:["inputStyles"],//⬅
data() {
return {
msg: "Getting the computed area here to change the background",
};
},
};
</script>
