Try to avoid curly braces(in slot-scope in your example) and arrow functions in inline templates if you work with IE11 (I had same problem in one of my projects):
<el-tree :data="tree" :props="treeProps">
<span slot-scope='someObject'>
<i class='el-icon-check'></i>
<span style="display:inline" v-html='someObject.node.label'></span>
</span>

I have been trying to get chips autocomplete to work as part of a project.
I have stripped code right back to remove any odd effects and replicated code as on the Materialize site. As in attached code I can get autocomplete to work as expected but not with chips.
I have tried with Chrome and Edge browsers and various combinations of tags and class names but still unable to make it work.
So now I need some help!
What have I missed?

console.log (options)
var autoElems = document.querySelectorAll('.autocomplete');
var attemptElems = document.getElementById("attempt");
var chipsElems = document.getElementById("chips-autocomplete");
var auto = M.Autocomplete.init(autoElems, options);
var chips = M.Chips.init(chipsElems, options);
});
</script>
</body>
</html>
The data init for chips-autocomplete is incorrect. From the docs:
$('.chips-autocomplete').chips({
autocompleteOptions: {
data: {
'Apple': null,
'Microsoft': null,
'Google': null
},
limit: Infinity,
minLength: 1
}
});
With Vanilla JS:
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.chips-autocomplete');
var instances = M.Chips.init(elems, {
autocompleteOptions: {
data: {
'Apple': null,
'Microsoft': null,
'Google': null
},
limit: Infinity,
minLength: 1
}
});
});
you are simply setting data (in quotes, when there should be no quotes). It should be autocompleteOptions as an object, and then data inside this.
i am very new to VueJS and want to build an Admin Dashboard for an existing bootstrap template (SB Admin Pro). I know there is a BootstrapVUE but we want to use the specified template that we purchased before. So this is not an option for me/us.
My Goal:
In our vue component we make an axios call to our backend to retrieve and show some data. If the call fails we want to call in the catch block a bootstrap function for toast to show some notification to the user (like: Error while fetching data from backend...). We included the bootstrap and jquery libraries from the template in the default index.html.
The Problem:
I don't know how to call the toasts (or other) functions from the vue component. In the template the call looks like this:
$("#toastBasic").toast("show");
Our index.html looks

In vue.config.js, specify jquery as external (this tells webpack where to provide jquery from when it's imported in any component):
configureWebpack: {
externals: {
jquery: 'window.jQuery'
}
}
Place all the <script>s you want loaded by the time Vue inits in your public/index.html page, in the <head> tag and remove their defer attribute. This includes any jquery plugin (or anything requiring/extending jquery) you might want to use in your Vue app (in your case, bootstrap.min.js).
The above will make it work when developing (in serve). You'll need to do the same for prod: Load jquery and any dependency before initing the Vue app.
Now you can safely use
import * as $ from 'jquery'
in any component.
Webpack will place in $ whatever window.jQuery is at the moment the component inits.
The above approach makes sure all required scripts are loaded before Vue inits (which is a bit extreme, but it makes sure there's no way you can call the jquery method before its dependencies are loaded).
If you don't want to wait for jquery and bootstrap.min.js to load before you init your Vue app, a trick you could use is to assign jquery from window object just before you need it:
yourAlertMethod() {
const $ = window.jQuery;
$.toast()...
}
Obviously, you no longer have to move all the scripts in <head> and to remove their defer. This second method doesn't guarantee they would have already loaded before your method is first used. But your app inits faster.
Here's a basic example.
I used the second method, codesandbox.io doesn't have support for #vue/cli v3 hence vue.config.js doesn't work as in a Vue project created with vue create. Therefore, I had to use the second method.
The full list of dependecies you need to load before you call the $(el).toast() method:
bootstrap.min.css
jquery.js
popper.js
bootstrap.min.js
(see them in public/index.html). You can copy/paste them from Bootstrap.
You can get ref of the element and pass it to jQuery
<div ref="toast" class="toast" id="toastBasic" role="alert" aria-live="assertive" aria-atomic="true" data-delay="5000">
import $ from 'jQuery';
$(this.$refs.toast).toast("show");
I don't recommend that though.
In my vue-bootstrap application I would like to use hidden input file control. When I use the standard input component it works (Load 1). If i try to do the same with the reactive component form vue-bootstrap library it does not work (Load 2). I would appreciate any hints what I might be doing wrong.
app = new Vue({
el: "#app",
data: {
files: '',
}
})

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">

<b-button #click="$refs.fileInput1.click()"> Load 1</b-button>
<input type="file" ref="fileInput1" style="display:none;"/>
</div>
<div>
<b-button #click="$refs.fileInput2.click()"> Load 2</b-button>
<b-form-file v-model="files" style="display:none;" ref="fileInput2" />
</div>
</div>
</body>
</html>
The $refs.fileInput2 here is referring to the Vue component, not really the input element, which is actually wrapped inside a div (you could see it if you inspect the rendered element). So one thing you could do (although it's ugly and not recommended, you should at least move this to the methods section):
app = new Vue({
el: "#app",
data: {
files: '',
}
})
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">

<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/bootstrap-vue#latest/dist/bootstrap-vue.js"></script>
<div id="app">
<div>
<b-button #click="$refs.fileInput1.click()"> Load 1</b-button>
<input type="file" ref="fileInput1" style="display:none;" />
</div>
<div>
<b-button #click="$refs.fileInput2.$el.querySelector('input[type=file]').click()"> Load 2</b-button>
<b-form-file v-model="files" style="display:none;" ref="fileInput2" />
</div>
</div>
Although I would say you should just use the native file input element since you are hiding the <b-form-file/> anyway.
It's working fine.You may check the below fiddle.
https://jsfiddle.net/tyagdvm5/
<b-form-file style="display:none;" v-model="file2" choose-label="Attachment2"></b-form-file>

I have an issue with loading Leaflet map using Vue.js and Bulma tab components (via Buefy).
If map is placed inside tab then it does not load all tiles until browser window is resized.
If map is placed outside of Bulma tabs component then it loads without any issue.
Calling map.invalidateSize() seems to help, but to do it automatically when tab changes I have to call it using setTimeout and put very big delay, like 1sec - which is very ugly.
How to get this working without this invalidateSize workaround?
Example with the issue: https://codepen.io/alxxnder/pen/zyYxwd
Example without the issue: https://codepen.io/alxxnder/pen/LMYEjr
Code:
new Vue({
el: '#app',
data: {
map: null,
},
methods: {
invalidateSize: function() {
this.map.invalidateSize();
}
},
mounted() {
this.map = L.map('map').setView([38.63, -90.23], 12);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(this.map);
}
})

As explained in Data-toggle tab does not download Leaflet map, the issue is caused by the fact that your map container does not have yet its full size when you initialize it. You may understand it more easily if your map had been in an initially hidden tab (e.g. in tab 2).
As for your initially active tab (i.e. tab 1), it is probable that Buefy / Bulma still takes some time to reveal the tab content.
Since there is no event when the tab transition completes, you have to wait for the transition duration before calling the invalidateSize method. In your case, 300ms seems to be fine.
Then you should also call it again when the user changes the tab (see Buefy tabs events), otherwise should the browser had changed size while your tab was hidden, the same issue would happen again.
Demo with maps in the 2 tabs:
new Vue({
el: '#app',
data: {
map: null,
map2: null,
tabMaps: []
},
methods: {
invalidateSize: function(tabIndex) {
setTimeout(() => {
if (typeof tabIndex === "number") {
this.tabMaps[tabIndex].invalidateSize();
} else {
// invalidate all maps
this.tabMaps.forEach(map => {
map.invalidateSize();
});
}
}, 300);
}
},
mounted() {
this.map = L.map('map').setView([38.63, -90.23], 12);
L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png').addTo(this.map);
// map2 in tab2
this.map2 = L.map(this.$refs.map2).setView([38.63, -90.23], 12);
L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png").addTo(
this.map2
);
this.tabMaps.push(this.map); // 0
this.tabMaps.push(this.map2); // 1
this.invalidateSize();
}
})

It's simple. Just change the double quotation marks used in template to single quotation marks.
you can't include the same quote mark inside the string if it's being used to contain them

template: "<h1>hello {{ name }}. <button v-on:click="chang">change name</button></h1>",
