"Using VueJS Slot directive to display dynamic content with v

Displaying a variable in the default scope - this method is functional.

<slot>{{namedSlotText}}</slot>

However, attempting it in another way results in the variable not being displayed.

Template

<div id="app">
  <my-component></my-component>
</div>

Code

let vm = new Vue({
  el:"#app",
  components:{    
    myComponent:{
      template:`
        <div>
         <slot :text="namedSlotText"></slot>
        </div>
      `,
      data:()=>({
        namedSlotText: "This is default slot text"
      })
    }
  }
})

I have seen instances where v-text has been successful.

Answer №1

When you provide a property to a slot, you are essentially offering data for use within the slot's content. This concept is known as scoped slots.

Take a look at this code snippet:

<div>
  <slot :text="namedSlotText"></slot>
</div>

This code snippet is solely providing access to the text property for use in the slot's content. To actually utilize this property, you must define a scoped template and then specifically refer to the property within the content.

<my-component>
  <template scope="{text}">
    {{text}}
  </template>
</my-component>

Avoid using arrow functions to declare data in Vue components. The correct ES2015 syntax for defining data inside components is as follows:

data() {
  return {
    namedSlotText: "This is default slot text"
  }
}

If you are using a standard slot, you can set the default value like this:

Vue.component('my-component', {
  template: `<div><slot>{{slotText}}</slot></div>`,
  data() {
    return {
      slotText: "This is default slot text"
    }
  }
})
