我遇到一个问题，我不知道如何使用 JavaScript 读取 test.json 文件。
Javascript代码:
<script type="text/javascript" src="test.json">
(function(){
var nytg = nytg || {};
$.getJSON("test.json", function(data) {
nytg.ipoData = data;
console.log(data);
});
}());
</script>
目前使用上面的代码，网站什么也没有显示。
这是我的 test.json 文件。

最佳答案
您正在像源文件一样加载 json 文件:
<script type="text/javascript" src="test.json">
该行应该是
<script type="text/javascript">
更新:将数据转储到控制台日志的完整示例:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<title>D3 example</title>
<style>
</style>
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>
<body>
<script>
(function(){
var nytg = nytg || {};
$.getJSON("24054047-test.json", function(data) {
nytg.ipoData = data;
console.log(data);
});
}());
</script>
</body>
</html>
wamp 服务器上的 console.log(第一个条目):
0: Object
BHRET3: -77.1
NAME: "SBE INC."
Obs: 1
fulldate: 20140108
rMVMP: 46.3313
rMVOP: 3000.9174
