Typically, when working with Vue.js, the recommended approach involves utilizing directives like v-if
, v-for
, or <component>
, depending on the specific task you are trying to accomplish:
- Implement
v-if
to conditionally display a component/element based on a set condition.
- Utilize
v-for
to render a list of components/elements.
- Use
<component>
for rendering a dynamic component/element.
To address the scenario you mentioned in your inquiry, you can define a boolean data property named visible
as follows:
data() {
return {
visible: false
}
}
You can then use v-if
to control the visibility of a component within the template:
<mycomponent v-if="visible"></mycomponent>
In cases where you are unsure of the specific component to display, you can include all possibilities in the template and show the desired one based on a condition:
<comp1 v-if="comp1Visible"></comp1>
<comp2 v-if="comp2Visible"></comp2>
<comp3 v-if="comp3Visible"></comp3>
Alternatively, you can utilize <component>
alongside another data property (comp
) which can be set to the component name you wish to display:
<component v-if="visible" :is="comp"></component>
The approach of using document.createElement
followed by el.appendChild
is not supported in Vue. Vue follows a strict rendering mechanism that you must adhere to; dynamically creating and appending components to the DOM at random is not feasible. While technically you can do comp = new Vue()
similar to document.createElement
and then el.appendChild(comp.$el)
, this would result in an independent Vue instance that needs to be manually managed without straightforward data transfer capabilities.
