Get the name from the number
- You can obtain data from the server using a fetch call.
- In these examples you will be getting data from /worldl.json this is a list of 195 countries in json format
- The program snippet shows the name of country 42.
- Change it so it shows the name of country 50.
- See if you can find your country.
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[42]; document.body.innerHTML = tgt.name; });
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[50]; document.body.innerHTML = tgt.name; });
Each country has a bunch of data associated, for example:
area: 330803 capital: "Kuala Lumpur" continent: "Asia" flag: "//upload.wikimedia.org/wikipedia/commons/6/66/Flag_of_Malaysia.svg" gdp: 304726000000 id: 102 name: "Malaysia" population: 30177000 tld: ".my"
Show the population
Alter your code so that the output matches the model answer.
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[102]; document.body.innerHTML = `<div>${tgt.name}</div>`; });
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[102]; document.body.innerHTML = `<div>${tgt.name}, ${tgt.capital}</div>`; });
Include image
Include div elements and an img for country 150
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[150]; document.body.innerHTML = `<div>${tgt.name}, ${tgt.capital}</div>`; });
fetch('/worldl.json') .then((r)=>r.json()) .then((r)=>{ let tgt = r[150]; document.body.innerHTML = ` <div>Name: ${tgt.name}</div> <div>Capital: ${tgt.capital}</div> <div>Population: ${tgt.population}</div> <img src='${tgt.flag}' style='width:100px'/> `; });
