I'm trying to show data from two separate ajax calls.
I've started experimenting with handlebars.js and managed to show data but only from one call. How can I refactor my code to show data from the second call as well?
HTML:
<header>
<img id="twitch-logo" src="https://upload.wikimedia.org/wikipedia/commons/c/c6/Twitch_logo_%28wordmark_only%29.svg">
</header>
<div id="result-placeholder"></div>
<script type="text/handlebars-template" id="handlebars-template">
{{#each this}}
<div class="result-wrapper">
<a href="{{channel.url}}" target="_blank">
<div><img src="{{channel.logo}}" class="result-logo"></div>
<div class="result-name">User: {{channel.display_name}}</div>
<div class="result-game">Currently streaming: {{channel.game}}</div>
</a>
</div>
{{/each}}
</script>
JS:
var streamers = ['monstercat', 'lirik'];
function getStream(name) {
return $.ajax('https://api.twitch.tv/kraken/streams/' + name + '?callback=?', { dataType: 'JSON' });
}
function displayStream(data) {
var $placeHolder = $("#result-placeholder");
var handlebarsTemplate = $("#handlebars-template").html();
var templateCompile = Handlebars.compile(handlebarsTemplate);
$placeHolder.html(templateCompile(data));
}
streamers.map(function(element) {
getStream(element)
.then(displayStream);
});
it looks like you are using jQuery to perform the http fetch of your streams. I suggest looking at the jQuery API, and use for instance jQuery.when( deferreds ) to combine async fetch of 2 or more resources:
