I have a <filter> component in a .vue file that has some properties to control the filter of a query.
This <filter> can be added / removed on-the-fly as the user needs. It's behavior is very similar to the Google Analytics segmentation filter, or Advanced Custom Fields from WordPress.
The only solution I see is instantiating this component dynamically and iterate over an array of these components inside my main app, but I don't exactly know how to do it.
Vue.component("my-filter", {
template: "#filterTemplate",
data: function() {
return {
field: null,
value: null
}
},
mounted: function() {
this.$emit("filter-created", this);
},
methods: {
removeFilter: function() {
console.log("Remove this filter");
}
}
});
var app = new Vue({
el: "#app",
data: {
filtersCount: 5,
filters: [] // PROBLEM! I can't decrement on my filtersCount and remove the correct filter. Iteration should be over my "filtersCount" property.
},
methods: {
filterCreated: function(filterObj) {
this.filters.push(filterObj);
},
addFilter: function() {
this.filtersCount += 1;
}
}
});* {
font-family: "Helvetica", "mono";
font-size: 16px;
}
.filterContainer + .filterContainer {
margin-top: 10px;
}
.filterContainer {
display: block;

<div id="app">
<!-- I shouldn't iterate over an integer value, but over an array of objects to remove the right ones -->
<my-filter v-on:filter-created="filterCreated" v-for="(index, filter) in filtersCount" :key="index"></my-filter>
