<div id="app">
<ul>
<!-- On mobile devices use short heading -->
<template v-if="mobile == 1">
<li><a href="#">Heading</a></li>
</template>
<!-- Else use long heading -->
<template v-else-if="mobile == 0">
<li><a href="#">Heading Long</a></li>
</template>
</ul>

var app = new Vue({
el: '#app',
data: {
mobile: 0
}
});
I'm looking for a way to change the value of 'mobile' when the screen breakpoint of (max-width: 547px) becomes active. And to change it back when this mobile breakpoint becomes inactive (screen goes over 547px). I normally use skel (https://github.com/ajlkn/skel) to deal with screen breakpoints, but I cannot access skel from inside Vue, or vice-versa. I would forego using Vue for this particular task, but display: none, and display: block throws off my presentation--turning my element into a block.
If you are using Vuetify, you can programmatically adjust the data value based on the built in breakpoints
of xs, sm, md, lg, xl (as specified in Material Design) as follows:
computed: {
mobile() {
return this.$vuetify.breakpoint.sm
},
}
mobile
will change to true
as soon as the screen width is less than 600px.
Your code would then be something like this (I also moved the if
statement to be directly on the <li>
element):
<div id="app">
<ul>
<!-- On mobile devices use short heading -->
<li v-if="mobile"><a href="#">Heading</a></li>
<!-- Else use long heading -->
<li v-else><a href="#">Heading Long</a></li>
</ul>
</div>
