Menu
i feel above logics for hover is incorrect. it just inverse when mouse hovers. i have used below code. it seems to work perfectly alright.
<div @mouseover="upHere = true" @mouseleave="upHere = false" >
<h2> Something Something </h2>
<some-component v-show="upHere"></some-component>
</div>
on vue instance
data : {
upHere : false
}
Hope that helps
Here is a working example of what I think you are asking for.
http://jsfiddle.net/1cekfnqw/3017/
<div id="demo">
<div v-show="active">Show</div>
<div @mouseover="mouseOver">Hover over me!</div>
</div>
var demo = new Vue({
el: '#demo',
data: {
active: false
},
methods: {
mouseOver: function(){
this.active = !this.active;
}
}
});
There's no need for a method here.
HTML
<div v-if="active">
<h2>Hello World!</h2>
</div>
<div v-on:mouseover="active = !active">
<h1>Hover me!</h1>
</div>
JS
new Vue({
el: 'body',
data: {
active: false
}
})
To show child or sibling elements it's possible with CSS only. If you use :hover before combinators (+, ~, >, space). Then the style applies not to hovered element.
HTML
<body>
<div class="trigger">
Hover here.
</div>
<div class="hidden">
This message shows up.
</div>
</body>
CSS
.hidden { display: none; }
.trigger:hover + .hidden { display: inline; }
With mouseover and mouseleave events you can define a toggle function that implements this logic and react on the value in the rendering.
Check this example:
var vm = new Vue({
el: '#app',
data: {btn: 'primary'}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<div id='app'>
<button
@mouseover="btn='warning'"
@mouseleave="btn='primary'"
:class='"btn btn-block btn-"+btn'>
{{ btn }}
</button>
</div>It's possible to toggle a class on hover strictly within a component's template, however, it's not a practical solution for obvious reasons. For prototyping on the other hand, I find it useful to not have to define data properties or event handlers within the script.
Here's an example of how you can experiment with icon colors using Vuetify.
new Vue({
el: '#app'
})<link href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons" rel="stylesheet">
<link href="https://cdn.jsdelivr.net/npm/vuetify/dist/vuetify.min.css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<script src="https://cdn.jsdelivr.net/npm/vuetify/dist/vuetify.js"></script>
<div id="app">
<v-app>
<v-toolbar color="black" dark>
<v-toolbar-items>
<v-btn icon>
<v-icon @mouseenter="e => e.target.classList.toggle('pink--text')" @mouseleave="e => e.target.classList.toggle('pink--text')">delete</v-icon>
</v-btn>
<v-btn icon>
<v-icon @mouseenter="e => e.target.classList.toggle('blue--text')" @mouseleave="e => e.target.classList.toggle('blue--text')">launch</v-icon>
</v-btn>
<v-btn icon>
<v-icon @mouseenter="e => e.target.classList.toggle('green--text')" @mouseleave="e => e.target.classList.toggle('green--text')">check</v-icon>
</v-btn>
</v-toolbar-items>
</v-toolbar>
</v-app>
