Using Vue.js with the slot-in attribute

Question

Using Vue.js with the slot-in attribute

Looking to create a unique vue.js template that functions as described below:

<CustomComponent></CustomComponent>

should produce

<div class="a"></div>

<CustomComponent>b</CustomComponent>

should result in

<div class="a" data-text="b"></div>

.

Is it possible to achieve this functionality?

UPDATE

Below is the closest solution I've come up with:

  props: {
    text: {
      type: [Boolean, String],
      default: false
    }
  },

and the corresponding template:

<template>
  <div :class="classes()" :data-text="text">
    <slot v-bind:text="text"></slot>
  </div>
</template>

However, there seems to be an issue with the binding, as text always returns false.

Answer №1

To retrieve text content from a component, you can utilize the mounted() method along with the $slot.default property. By creating a data field for text and updating it inside the mounted() method, you can easily access the enclosing text. Here's an example:

Vue.component('mycomponent', {
  data: () => ({
    text: ""
  }),
  template: '<div class="a" :data-text=text></div>',
  mounted(){
    let slot = this.$slots.default[0];
    this.text=slot.text;

  }
});

Please note that this approach is suitable for retrieving text content only, and may not work with HTML tags or other components.

It seems like you're blending slots and properties together in your code. To set the data-text attribute in your component, you'll need to pass the desired value as a prop.

<MyComponent text="'b'"></MyComponent>

In your template, you can then eliminate the slot:

<template>
    <div :class="classes()" :data-text="text"></div>
</template>

Additionally, it appears that you are binding your classes using a method. Consider utilizing computed properties for this purpose instead if you are unfamiliar with them.

Feel free to give this a shot.

<template>
  <div :class="classNames()">
    <slot name="content" v-bind:text="textContent" v-if="hasDefaultSlot">
    </slot>
  </div>
</template>

computed: {
    hasDefaultSlot() {
        console.log(this)
        return this.$scopedSlots.hasOwnProperty("content");
    },
}

<MyComponent>
<template v-slot:content="info">

</template>
</MyComponent>
