I'm using a service to load my form data into an array in my angular2 app. The data is stored like this:
arr = []
arr.push({title:name})
When I do a console.log(arr), it is shown as Object. What I need is to see it
as [ { 'title':name } ]. How can I achieve that?
you may use below,
JSON.stringify({ data: arr}, null, 4);
this will nicely format your data with indentation.
console.log(JSON.stringify(arr)) if you don't need the formatting and just want to see how the object might be passed to a REST endpoint or the like.To print out readable information. You can use console.table() which is much easier to read than JSON:
console.table(data);
This function takes one mandatory argument data, which must be an array or an object, and one additional optional parameter columns.
It logs data as a table. Each element in the array (or enumerable property if data is an object) will be a row in the table
Example:
console.table(x). looks nice!first convert your JSON string to Object using .parse() method and then you can print it in console using console.table('parsed sring goes here').
e.g.
const data = JSON.parse(jsonString);
console.table(data);
Please try using the JSON Pipe operator in the HTML file. As the JSON info was needed only for debugging purposes, this method was suitable for me. Sample given below:
<p>{{arr | json}}</p>
You could log each element of the array separately
arr.forEach(function(e){console.log(e)});
Since your array has just one element, this is the same as logging {'title':name}
you can print any object
console.log(this.anyObject);
when you write
console.log('any object' + this.anyObject);
this will print
any object [object Object]
console.log(JSON.stringify(arr))
