I am learning VueJS 2.0 and I am connecting to an API where I want the value of some data to change on input change. Here is what the output says using the dev tools:
canadianDollar:undefined
europeanEuro:undefined
europeanPound:undefined
usd:"1232"
Whenever I put 1232 in the USD input field it doesn't return anything and leaves those properties as undefined. Here is the code.
new Vue({
el: '#app',
data: {
usd: '',
canadianDollar: '',
europeanPound: '',
europeanEuro: ''
},
// Watch methods
watch: {
usd: function() {
this.convertCurrency()
}
},
// Logic Methods
methods: {
convertCurrency: _.debounce(function() {
var app = this;
if (app.usd.length !== 0) {
// Show that the things are loading in.
app.canadianDollar = 'Searching...'
app.europeanPound = 'Searching...'
app.europeanEuro = 'Searching...'
console.log(app.usd)
axios.get("http://api.fixer.io/latest?base=USD&" + app.usd)
.then(function(response) {
app.canadianDollar = response.data.CAD
app.europeanPound = response.data.GBP
app.europeanEuro = response.data.EUR
})
.catch(function(error){
app.canadianDollar = "ERROR"
app.europeanPound = "ERROR"
app.europeanEuro = "ERROR"
})
}
}, 500)
}
})
and the HTML:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to Vue</title>
<script src="https://unpkg.com/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<input type="text" name="" value="" v-model="usd">
<ul>
<li>Canadian Dollar: {{canadianDollar}}</li>
<li>European Pound: {{europeanPound}}</li>
<li>European Euro: {{europeanEuro}}</li>
</ul>
</div>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script src="https://cdn.jsdelivr.net/lodash/4.17.4/lodash.min.js" charset="utf-8"></script>
<script src="index.js" charset="utf-8"></script>
</body>
</html>
When I type in a number it does give me the "Searching" part but disappears and nothing shows up.
