Question

它适用于Chrome和其他所有浏览器，而不是IE，我在下面做了一个例子：

http://develop.davzy.com/test1.php

（谈论IE 8，我不确定它是否在9中运行正常）

当我运行JSON请求时，我收到一个错误，指出对象是预期的。这发生在第29行。

<!DOCTYPE html> 
<html> 
  <head> 
  <title>Sandbox</title> 
    <script src="http://code.jquery.com/jquery-1.4.4.min.js"></script>
</head> 
<script>

function search()
{
    $.ajax({ 
        url: 'http://davzy.com/cache/api/rarevalues.php?callback=?&search=' + $('input').val(),
        cache: false,
        dataType: 'json',
        success: function(data, status, xhr) {
            $('body').append('<br>' + data[0].name);
            $('input').focus().val('');
        }
    });
}

</script>
<body> 
    <div>type test or rare or chair</div>
    <input onkeydown='if(event.keyCode == 13) search();'>
    <button onclick='search()'>Go</button>
</body>
</html>

以下是它返回的JSON示例（回调工作正常，忽略？这来自http://davzy.com/cache/api/rarevalues.php?callback=?&search=petal）

Strimp099是正确的，我需要标题（'content-type：application / json; charset = utf-8'）;我的IE将其视为JSON。谢谢！

Answer 2

这里的答案解释了所有：JavaScript KeyCode Values are "undefined" in Internet Explorer 8

请改为尝试：

var keyCode = (window.Event) ? e.which : e.keyCode;
if (keyCode == 13) {
    search();
}

此外，我相信当您在输入字段上输入时，您的按钮点击可能会触发。所以你要两次调用搜索。如果你改变了怎么办？

<button onclick='search()'>Go</button>

到：

<input type="text" onclick='search()' value="Go" />？

为什么这个JSON不会在IE中运行
