如何显示我的 YQL/xpath/javascript？
作为练习，我尝试使用 YQL/xpath/javascript 在远程页面上显示塔罗牌图片、卡片名称和含义。我已经像雅虎上的示例一样设置了脚本，但无法让它在浏览器中显示。关于如何改进它以使其显示有什么建议吗？
<html>
<head>
<title>Example</title>
<script type='text/javascript'>
function tarot(o){
var div = o.query.results.div;
var output = '';
var title = div[0].strong;
var content = div[0].p.content;
var src = div[1].img.src;
output = "<h3>" + title + "</h3></br><p>" + content + "</p><img src='" + src + "' alt="" />";
document.getElementById('results').innerHTML = output;
}
</script>
</head>
<body>
<div id='results'></div>
<script src="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.tarot.com%2Fdaily%22%20and%20xpath%3D%22%2F%2Fdiv%5B%40id%3D'cardHolder'%5D%20%7C%20%2F%2Fdiv%5B%40id%3D'cardMeaning'%5D%22&format=json&diagnostics=true&callback=tarot"></script>
</body>
</html>
非常感谢任何帮助！ 〜拉里斯
P.S. - 我更新了代码的 callback=functionName 部分以反映最新的代码。不幸的是，这似乎并不能解决问题。我似乎还缺少其他东西吗？
As an exercise, I'm trying to display a tarot card picture, the name of the card, and the meaning on a remote page using YQL/xpath/javascript. I've set up the script like the example on Yahoo but can't get it to display in the browser. Any suggestions as to how to improve it so it will display?

var output = '';

var content = div[0].p.content;
var src = div[1].img.src;
output = "<h3>" + title + "</h3></br><p>" + content + "</p><img src='" + src + "' alt="" />";
document.getElementById('results').innerHTML = output;
}
</script>

<script src="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.tarot.com%2Fdaily%22%20and%20xpath%3D%22%2F%2Fdiv%5B%40id%3D'cardHolder'%5D%20%7C%20%2F%2Fdiv%5B%40id%3D'cardMeaning'%5D%22&format=json&diagnostics=true&callback=tarot"></script>
</body>
</html>
Any help is greatly appreciated!

P.S. - I updated the callback=functionName part of the code to reflect the most current code. Unfortunately, this doesn't seem to fix the problem. Is there something else I seem to be missing?

您有
callback=cbfunc，但尚未定义function cbfuncYou have
callback=cbfuncbut you haven't definedfunction cbfunc我发现的问题是您从未调用
tarot()函数。我认为你应该将你的 url 结尾更改为
callback=tarot希望这会有所帮助。干杯
The problem I see is that you're never calling your
tarot()function.I think you should change your url end to
callback=tarotHope this helps. Cheers
