i'm new to es6 and i have an array of objects like below:
checkProps = [ {symbol: rwerwe}, {side: Buy}, {status: Hey} ]
With a for loop i want to create a string like: myurl = localhost:3000/symbol=rwerwe&side=Buy&status=Hey
For this i have to get access to the keys of each object and use concat for the string composition. I used Object.keys but it returns integers. I want something to return the symbol, side and status. How to do this?
Please try this:
var checkProps = [ {symbol: 'rwerwe'}, {side: 'Buy'}, {status: 'Hey'} ];
var urlStr = 'localhost:3000/';
var urlParams = [];
checkProps.forEach(function(o) {
var keys = Object.keys(o);
keys.map(function(key) {
urlParams.push(key + '=' + o[key])
});
});
urlStr += urlParams.join('&');
console.log(urlStr)
You need to loop over the array and apply Object.keys to the items.
const parameters = checkProps.map(item => Object.keys(item).map(key => key + "=" + item[key])[0])
.join("&");
const myUrl = `localhost:3000/${parameters}`;
It's a bit cleaner with ES2017 and Object.entries:
const parameters = checkProps.map(item => Object.entries(item)[0])
.map(parameter => parameter.join("="))
.join("&");
