How to i get the data from from [Object object]?

如何从[Object]获取数据?

Here is an example of what i'm trying to do.

这是我要做的一个例子。

// Get data with dirty
var data = db.get('/htmltest')

// My test.db file
{"key":"foo","val":"barwhat?"}
{"key":"/htmltest","val":{"title":"Html Test","content":"<span>This is HTML</span>"}}


// the console.log gives me [Object Object]
// How do I get it to show the content of title (Html Test)
console.log(data);

3 个解决方案

#1

According to the documentation, the get method returns the value for a given key. In that case you should be able to access the title property like so:

根据文档，get方法返回给定键的值。在这种情况下，您应该能够访问title属性如下:

// Get data with dirty
var data = db.get('/htmltest')

// My test.db file
{"key":"foo","val":"barwhat?"}
{"key":"/htmltest","val":{"title":"Html Test","content":"<span>This is HTML</span>"}}


// the console.log gives me [Object Object]
// How do I get it to show the content of title (Html Test)
console.log(data.title);

Another thing that you can do to help view your data for debugging is to use the util inspect function.

另一种帮助查看数据进行调试的方法是使用util inspect函数。

var util = require('util');
var data = db.get('/htmltest');

console.log(util.inspect(data));

Again, this is only useful for debugging and inspecting the contents of objects.

同样，这只对调试和检查对象的内容有用。

If you certify that your data variable is a JSON object, you can also parse easily it and show all content in one row using JSON.stringify(data);

如果您证明您的数据变量是一个JSON对象，您也可以使用JSON.stringify(data)轻松解析它并在一行中显示所有内容;
