Console.Log（对象编号）-对象的对象

Question

Using Angular2 and Firebase I'm retrieving a news article.

I log my retrieved data and its appearing as an Object with an array of Objects but there is only 1 item in the array starting at 39 .

Can i get the 39 so i can retrieve this object?

Or is there another way?

Thanks

    this._ReturnsService.fetchDataId(id)
        .subscribe((data) => {
            console.log(data);
            this.news = data[39];
            this.bodyofartical = this.news.body.replace(/\n/g, '<br />');
        })

Answer 1

您可以执行Object.keys(data)[0]来返回您要查找的39 。

Answer 2

You can start with following code and expend as needed.

this._ReturnsService.fetchDataId(id)
    .subscribe((data) => {
        console.log(data);
        data.forEach( d => {
            this.bodyofartical = d.news.body.replace(/\n/g, '<br />');
        }
    })

With above code you don't have to worry about index id.

The code will loop through the whole data array.

You will have to modify the loop if there is more than 1 item in data array, else this.bodyofartical will always get the last article in the array.
