I am retrieving data from an API that looks like this -
"title": "Company Name",
"markets": "US, Asia",
"market_ids": "4, 5"
I need to add this data to a dropdown menu like this -
<option value="4">US</option>
So I need to remove the commas and any duplicates (there will be many entries with the same market)
I was thinking something like this at first -
$.ajax({
method: 'GET',
url: 'http://localhost:9001/api/directory',
}).done(function (data, status, xhr) {
let markets = [];
$.each(data, function (index, value) {
markets.push(value.markets);
})
markets = [...new Set(markets.toString().split(','))];
for (market of markets) {
$(".directory-input.market").append(
`<option value="" class="market-option">${market}</option>`)
};
});
This works to separate the market names by comma and get rid of any duplicates, but the problem is that I can't add the market ID to the value. I need the market ID to be accessible as well.
If you have control of the API design, something like
{
title: 'Company Name',
markets: [
{ id: 4, name: 'Asia' },
{ id: 4, name: 'US' }
]
}would make usage easier and more clear.
Given the example though, and making a couple assumptions:
this should work
$
.ajax({
method: 'GET',
url: 'http://localhost:9001/api/directory',
})
.done((data, status, xhr) => {
const marketSelect = $(".directory-input.market");
const labels = Array.from(new Set(data.markets.split(', ')));
const ids = Array.from(new Set(data.market_ids.split(', ')));
labels.forEach(
(label, idx) =>
marketSelect.append(`<option value="${ids[idx]}" class="market-option">${label}</option>`)
);
});Assuming there will be the same number of ids and markets. Note, if you are adding a a lot of options, you probaly will want to create the select itself with options as a documentFragment to avoid repaints.
const data = {
"title": "Company Name",
"markets": "US, Asia, Asia",
"market_ids": "4, 5, 5"
};
const marketSelectEl = document.getElementById('market-select');
const markets = Array.from(
new Set(data.markets.split(',').map(m => m.trim()))
);
const market_ids = Array.from(
new Set(data.markets.split(',').map(m => m.trim()))
);
const marketOptions = markets
.map((marketName, index) => {
const optionEl = document.createElement('option');
optionEl.value = market_ids[index];
optionEl.innerText = marketName;
return optionEl;
})
;
marketOptions.forEach(el => marketSelectEl.append(el));<select id="market-select" style="width: 200px;">
</select>
