Guide to attaching a Vue instance to an HTML element that has not been added yet

I'm currently working on an app where I need to attach a Vue instance to an HTML Node. However, I am facing an issue after using the $mount function as the Node does not seem to contain the Vue instance.

The code snippet below showcases my goal. I aim to produce an HTML Node that holds the Vue instance within it.

const el = document.createElement('div');
new Vue({
  render(createElement) {
    return createElement(HelloWorldVue, {}, {});
  },
  components: {
    HelloWorldVue,
  },
}).$mount(el);
return el;

If anyone has any insights or suggestions on how to properly mount the Vue instance to the element before displaying it, please share them with me. Thank you!

javascriptvue.jsdom

Answer №1

As mentioned in the documentation:

In Vue 1.x, the mounted element will be replaced with Vue-generated DOM in all scenarios.

Therefore, this method will not work. However, a similar outcome can be achieved by using $mount() and excluding any arguments:

If the elementOrSelector argument is omitted, the template will be rendered as an off-document element, requiring the use of native DOM API to manually insert it into the document.

// alternatively, render off-document and append later:
var component = new MyComponent().$mount()
document.getElementById('app').appendChild(component.$el)
