How to specify multiple dynamic attributes by single computed prop in VueJS - vue.js

Question

I have this html element:
Link text
I want to add data-tooltip and title attributes dynamically by condition:
Link text
Is there any way in VueJS to add multiple dynamic attributes at same time:
<!-- instead of this: -->
Link text
<!-- something like this: -->
<a href="javascript:" ...tooltipAttributes >Link text</a>

Answer 1

You could take advantage of v-bind on the DOM element you wish to apply multiple attributes to based on some dynamically changing condition.
Here's a Plunker example demonstrating how you might go about it.
Take note of the object returned:
computed: {
multiAttrs() {
return this.showAttrs ? {
'data-toggle': 'tooltip',
title: 'Some tooltip text',
} : null;
}
}

Answer 2

You should be able to use v-bind="tooltipAttributes"
the docs here https://v2.vuejs.org/v2/api/#v-bind have more info, but the key part is under usage
Dynamically bind one or more attributes, or a component prop to an expression.

Answer 3

From the Docs:
1. You can dynamically bind multiple attributes/props to a single element by using v-bind:
(no colon, no extra attribute, just v-bind)
<a href="#" v-bind="tooltipAttributes" >Link text</a>
2. And then declare the variable in the computed section:
(you can also declare it in the data section, but that would require manual direct value changes)
computed() {
return {
tooltipAttributes: {
title: 'Title',
'data-toggle': this.toggle === true && !disabled
}
}
}
Note: Attributes with dashes/hyphens - in them (e.g. data-toggle) need to be a string because Javascript doesn't recognize - as a valid symbol in variable naming.
This is THE SAME AS:
<a href="#" title="Title" :data-toggle="this.toggle === true && !disabled" >Link text</a>
