[英]JSON.stringify returns “[object Object]” instead of the contents of the object
Here I'm creating a JavaScript object and converting it to a JSON string , but JSON.stringify
returns "[object Object]"
in this case, instead of displaying the contents of the object. 这里我创建一个JavaScript对象并将其转换为JSON字符串 ,但在这种情况下
JSON.stringify
返回"[object Object]"
,而不是显示对象的内容。 How can I work around this problem, so that the JSON string actually contains the contents of the object? 我该如何解决这个问题,以便JSON字符串实际上包含对象的内容?
var theObject = {name:{firstName:"Mark", lastName:"Bob"}};
alert(JSON.stringify(theObject.toString())); //this alerts "[object Object]"
使用alert(JSON.stringify(theObject));
theObject.toString()
The .toString()
method is culprit. .toString()
方法是罪魁祸首。 Remove it; 去掉它; and the fiddle shall work: http://jsfiddle.net/XX2sB/1/

JSON.stringify returns "[object Object]" in this case
在这种情况下,JSON.stringify返回“[object Object]”
That is because you are calling toString()
on the object before serializing it: 那是因为在序列化之前你在对象上调用
toString()
:
JSON.stringify(theObject.toString()) /* <-- here */
Remove the toString()
call and it should work fine: 删除
toString()
调用,它应该工作正常:
alert( JSON.stringify( theObject ) );
Use 使用
var theObject = {name:{firstName:"Mark", lastName:"Bob"}};
alert(JSON.stringify(theObject));
