I've been utilizing a service to input my form data into an array within my angular2 application. The information is organized in the following manner:
arr = []
arr.push({title:name})
After executing console.log(arr), it displays as Object. However, I am aiming to have it represented as [ { 'title':name } ]. Is there a way to accomplish this?
Feel free to utilize the following code snippet:
JSON.stringify({ information: array}, null, 4);
By using this, your data will be neatly organized with proper indentation.
If you want to display information in a readable format, consider using the console.table() method as it provides a more organized output compared to JSON:
console.table(data);
This function requires one main argument which is data, and it can either be an array or an object. Additionally, you can provide another optional parameter called columns.
When executed, it presents the data in a tabular format. Each item in the array (or property in case of an object) will represent a row in the table.
For example: https://i.sstatic.net/Hy8VJ.png
To begin, transform your JSON string into an Object by utilizing the .parse() method. After that, you can display it in the console using
console.table('insert parsed string here')For example:
const information = JSON.parse(jsonString);
console.table(information);
I found that utilizing the JSON Pipe operator within the HTML file helped streamline my debugging process. This method proved to be quite effective as the JSON information was only necessary for troubleshooting purposes. Check out the example below:
<div>{{data | json}}</div>
To capture each item in the array individually, iterate over each element
arr.forEach(function(item){console.log(item)});
If your array contains only one item, it's equivalent to logging {'title':name}
It is possible to display any item.
console.log(this.itemToDisplay);
By entering the following code:
console.log('item to display' + this.itemToDisplay);
The output will show:
item to display [object Object]
