How can I set a composed property (like composed_prop.foo) from HTML?
The normal_prop sets well but composed_prop.foo doesn't.
Example:
<div id="app">
<sample normal_prop=1 composed_prop.foo=1 />
</div>
<script>
Vue.component('sample',{
props: {
normal_prop: 0,
composed_prop: {
default:{
foo: 0,
bar: 0
}
}
}
})
new Vue({
el: "#app"
})
</script>
You have to do it like this:
<div id="app">
<sample normal_prop=1 :composed_prop="{foo:10, bar:20}" />
</div>
Note that you have to bind the composed_prop so the expression will be evaluated (rather than treating it as a literal string). Also note that passing in an object for composed_prop will completely overwrite your defaults - it won't try to merge the properties with the defaults. So, if you only pass in {foo:10}, then composed_prop.bar will be undefined.
One final note... I think the default for an Object prop should be a factory function. Something like this:
Vue.component('sample',{
props: {
normal_prop: 0,
composed_prop: {
type: Object,
default:function(){ // should be a function
return { foo: 0, bar: 0 };
}
}
}
})
