Implementing Conditional Attribute Addition in Vue.js

Question

Implementing Conditional Attribute Addition in Vue.js

When developing in vue, I encountered this scenario:

<v-dialog v-model="data_table.dialog">

I have a variable called is_mobile that is observable. My goal is to modify the tag above based on the value of is_mobile. For instance:

<v-dialog v-model="data_table.dialog">

should be displayed when is_mobile is false. However, it should appear like this instead:

<v-dialog fullscreen hide-overlay transition="dialog-bottom-transition" v-model="data_table.dialog">

when is_mobile is true.

How can I achieve this effect?

I am only familiar with setting attribute values, but in this case, I need to include or exclude attributes entirely depending on the condition. Also, for the transition, the attribute and value should either both be present or absent, as shown above, rather than using fullscreen="true"/fullscreen="false".

Thank you

Answer №1

If you want to dynamically set attributes or bindings in Vue.js, you can achieve this using the v-bind directive.

One way to do this is by creating a computed property like the following example:

computed: {
  dynamicBindings () {
    if (!this.is_mobile) {
      return {
        fullscreen: true,
        hideOverlay: true,
        transition: 'dialog-bottom-transition'
      }
    }
    return {}
  }
}

You can then use these dynamic bindings inside your component's template as shown below:

<v-dialog   
  v-model="data_table.dialog"
  v-bind="dynamicBindings"
>
