Question

我有以下代码来检索json响应。我需要提取属性'申请人'并将其放到html文本字段中。但是我不知道怎么做。我可以在控制台中看到响应，但文本字段显示[object Object]，如何将其检索到文本字段？任何提示？谢谢。

<html>
<head>
<script type="text/javascript" 

src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">


document.getElementById('sudata').value = budata;

}
});
</script>
</head>
<body>
<form name="form1" id="form1">
<input type="text" name="sudata" id="sudata" value="" size="100">
</form>
</body>
</html>

您的budata变量包含一个数组。元素的value属性是一个字符串属性，因此当您为其指定一个对象时，该对象首先使用Object :: toString（）进行转换;这将返回[object Object]。

如果您要显示申请人财产的全部内容，请尝试：

document.getElementById( 'sudata' ).value = JSON.stringify( budata );

如果您只是尝试显示数组的特定部分，则必须指定预期的输出字符串。

从json响应中解析属性
