I have a JSON array structured like this:
var region= [{"af":"Africa"},{"as":"Asia"},{"au":"Australia"}]
Within the framework I am using, the values of the above array are accessed in the following way:
{for r in regions}
<option value="${r}" >${r}</option>
{/for}
I attempted to use JavaScript but was unsuccessful. I am looking for assistance with achieving the desired output as shown above.
Please help me out with this.
let continents = [{"af":"Africa"},{"as":"Asia"},{"au":"Australia"}],
total = continents.length,
index, property;
for (index = 0; index < total; ++index) {
property = Object.keys(continents[index])[0];
console.log(property, continents[index][property]);
}
Object.keys in the provided code generates an array of all keys within the object. In scenarios where each object contains just one key, you can access it directly by using [0]
