My Vue component is like this :
<template>
<div>
<div class="panel-group"v-for="item in list">
<div class="col-md-8">
<small>
Total: <b>{{ item.total }}</b>
</small>
</div>
</div>
</div>
</template>
<script>
export default {
...
computed: {
list: function() {
return this.$store.state.transaction.list
},
...
}
}
</script>
The result of {{ item.total }}
is
26000000
But I want format it to be like this :
26.000.000,00
In jquery or javascript, I can do it
But, How to do it in vue component?
I have created a filter. The filter can be used in any page.
Vue.filter('toCurrency', function (value) {
if (typeof value !== "number") {
return value;
}
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD'
});
return formatter.format(value);
});
Then I can use this filter like this:
<td class="text-right">
{{ invoice.fees | toCurrency }}
</td>
I used these related answers to help with the implementation of the filter:
How to format numbers as currency strings
Check whether variable is number or string in JavaScript
UPDATE: I suggest using a solution with filters, provided by @Jess.
I would write a method for that, and then where you need to format price you can just put the method in the template and pass value down
methods: {
formatPrice(value) {
let val = (value/1).toFixed(2).replace('.', ',')
return val.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")
}
}
And then in template:
<template>
<div>
<div class="panel-group"v-for="item in list">
<div class="col-md-8">
<small>
Total: <b>{{ formatPrice(item.total) }}</b>
</small>
</div>
</div>
</div>
</template>
BTW - I didn't put too much care on replacing and regular expression. It could be improved.enter code here
Vue.filter('tableCurrency', num => { if (!num) { return '0.00'; } const number = (num / 1).toFixed(2).replace(',', '.'); return number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ','); });
return (value/1).toFixed(2).toLocalString();
?
computed
instead?
With vuejs 2, you could use vue2-filters which does have other goodies as well.
npm install vue2-filters
import Vue from 'vue'
import Vue2Filters from 'vue2-filters'
Vue.use(Vue2Filters)
Then use it like so:
{{ amount | currency }} // 12345 => $12,345.00
Ref: https://www.npmjs.com/package/vue2-filters
You can format currency writing your own code but it is just solution for the moment - when your app will grow you can need other currencies.
There is another issue with this:
For EN-us - dolar sign is always before currency - $2.00, For selected PL you return sign after amount like 2,00 zł.
I think the best option is use complex solution for internationalization e.g. library vue-i18n( http://kazupon.github.io/vue-i18n/).
I use this plugin and I don't have to worry about such a things. Please look at documentation - it is really simple:
http://kazupon.github.io/vue-i18n/guide/number.html
so you just use:
<div id="app">
<p>{{ $n(100, 'currency') }}</p>
</div>
and set EN-us to get $100.00:
<div id="app">
<p>$100.00</p>
</div>
or set PL to get 100,00 zł:
<div id="app">
<p>100,00 zł</p>
</div>
This plugin also provide different features like translations and date formatting.
The comment by @RoyJ has a great suggestion. In the template you can just use built-in localized strings:
<small>
Total: <b>{{ item.total.toLocaleString() }}</b>
</small>
It's not supported in some of the older browsers, but if you're targeting IE 11 and later, you should be fine.
I used the custom filter solution proposed by @Jess but in my project we are using Vue together with TypeScript. This is how it looks like with TypeScript and class decorators:
import Component from 'vue-class-component';
import { Filter } from 'vue-class-decorator';
@Component
export default class Home extends Vue {
@Filter('toCurrency')
private toCurrency(value: number): string {
if (isNaN(value)) {
return '';
}
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
minimumFractionDigits: 0
});
return formatter.format(value);
}
}
In this example the filter can only be used inside the component. I haven't tried to implement it as a global filter, yet.
You can use this example
formatPrice(value) {
return value.toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, '$1,');
},
There is issues with the precision of the accepted answer.
the round(value, decimals) function in this test works. unlike the simple toFixed example.
this is a test of the toFixed vs round method.
http://www.jacklmoore.com/notes/rounding-in-javascript/
Number.prototype.format = function(n) { return this.toFixed(Math.max(0, ~~n)); }; function round(value, decimals) { return Number(Math.round(value+'e'+decimals)+'e-'+decimals); } // can anyone tell me why these are equivalent for 50.005, and 1050.005 through 8150.005 (increments of 50) var round_to = 2; var maxInt = 1500000; var equalRound = '
mixin example
export default { methods: { roundFormat: function (value, decimals) { return Number(Math.round(value+'e'+decimals)+'e-'+decimals).toFixed(decimals); }, currencyFormat: function (value, decimals, symbol='$') { return symbol + this.roundFormat(value,2); } } }
val.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")
after that for the . and , changes.
Try this:
methods: {
formatPrice(value) {
var formatter = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'PHP',
minimumFractionDigits: 2
});
return formatter.format(value);
},
}
Then you can just call this like:
{{ formatPrice(item.total) }}
numeral.js is a JavaScript library for formatting and manipulating numbers.
You can format a currency so easily using it.
For example,
// price = 1200
{numeral(price).format(`$0,0.00`)}
// result $1,200.00
Here's the documentation. http://numeraljs.com/
Success story sharing
isNaN(parseFloat(value))
rather thantypeof value !== "number"
?minimumFractionDigits: 0
. I expect most people wanting to format numbers as currencies will, like me, want to have 2 decimal places displayed, e.g. $5.90, rather than $5.9. In that case you can either specifyminimumFractionDigits: 2
, or indeed just leave that line out altogether since if usingstyle: 'currency'
it will default to 2 anyway. Hope this helps someone...
