我已经创建了下面的代码,但它无法正常工作。我哪里出错了,或者我忘了包括什么?
var search = document.getElementById("search").value;
var xhr = new XMLHttpRequest();
function results() {
console.log(search);
xhr.send()
}
document.getElementById("results").innerHTML = results();
// Send the XHR
xhr.open('GET', 'https://api.soundcloud.com/tracks?client_id=1dff55bf515582dc759594dac5ba46e9&q=" + search;', true);
<html>
<head>
<!-- JS -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
</head>
<body>
<input type="search" id="search" />
<button onclick="results()">Search</button>
<p id="results"></p>
</body>
</html>

您的代码将在页面加载时运行,但您希望创建一个事件监听器,等待用户按下“搜索”然后执行您的请求。
尝试:
$('#search').click(function(){
var search = document.getElementById("search").value;
var xhr = new XMLHttpRequest();
var results = xhr.open('GET', 'https://api.soundcloud.com/tracks?client_id=1dff55bf515582dc759594dac5ba46e9&q=" + search;', false);
document.getElementById("results").innerHTML = results;
})
xhr请求中的'false'参数会阻止代码异步运行,但我相信你可以以某种方式使用回调?

想出来......
function audioResults(){
var search = document.getElementById("search").value;
var xhr = new XMLHttpRequest();
xhr.open('GET', "https://api.soundcloud.com/tracks?client_id=1dff55bf515582dc759594dac5ba46e9&q=" + search, false);
xhr.addEventListener("load", function() {
document.getElementById("results").innerHTML = xhr.response;
}, false);
xhr.send();
}
