I am trying to get to a point where I can have multiple component types being rendered within a single parent. It's not something which is easy to search for answers on.
I know that it is differentiating the components by adding something to the templates to distinguish them, but if I pass data as you'll see below, I get nothing, any tips?
Edit: I also don't want to have to render out these components in the HTML for this to work, needs to be passed in via JS.
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<div id="app">
<component v-for="widget in widgets" :is="widget.type"></component>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<script>
Vue.config.debug = true
Vue.component('component-a', {
template: '<p>{{foo}}</p>',
props: ['foo',]
});
Vue.component('component-b', {
template: '<p>{{bar}}</p>',
props: ['bar',]
});
new Vue({
el: "#app",
data: {
widgets: [
{
type: "component-a",
foo: 'Hello'
},
{
type: "component-b",
bar: "World",
},
]
}
});
</script>
</body>
</html>
The issue is that you're not passing any props for the foo and bar elements
<!doctype html>
<html>
<head>
<title></title>
</head>
<body>
<div id="app">
<component v-for="widget in widgets" :is="widget.type" :foo="widget.foo" :bar="widget.bar"></component>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<script>
Vue.config.debug = true
Vue.component('component-a', {
template: '<p>{{foo}}</p>',
props: ['foo',]
});
Vue.component('component-b', {
template: '<p>{{bar}}</p>',
props: ['bar',]
});
new Vue({
el: "#app",
data: {
widgets: [
{
type: "component-a",
foo: 'Hello'
},
{
type: "component-b",
bar: "World",
},
]
}
});
</script>
</body>
</html>
In your example the components are rendering with empty strings so you're not seeing the values you're trying to pass. when using interchangeable components it's often best to use a common value interface. Something along the lines of:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<div id="app">
<component v-for="widget in widgets" :is="widget.type" :value="widget.value"></component>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<script>
Vue.config.debug = true
Vue.component('component-a', {
template: '<p>{{value.foo}}</p>',
props: ['value',]
});
Vue.component('component-b', {
template: '<p>{{value.bar}}</p>',
props: ['value',]
});
new Vue({
el: "#app",
data: {
widgets: [
{
type: "component-a",
value: {
foo: 'Hello'
}
},
{
type: "component-b",
value: {
bar: "World",
}
},
]
}
});
</script>
</body>
</html>
So that the components only pass the single value object to the component necessary and the component pulls the unique values from that object.
