Storing values from multiple select into definition expression

TheGamer — Fri, 27 Jan 2023 15:53:39 GMT

So I have a multiple-select option and I was wondering how do I retrieve the values from the multi-select and assign it to the following layer expression:

map.allLayers.forEach((layer) => { layer.definitionExpression = "CSDNAME IN"; layer.queryExtent().then(function (results) { view.goTo(results.extent); }); });

You can get the values from the multi-select and turn them into a string, which would be then used in the definition expression

const options = document.getElementById('your-multi-select').selectedOptions; const values = Array.from(options).map(({ value }) => "'" + value + "'"); //if the values are numbers, omit the quotes //const values = Array.from(options).map(({ value }) => value); const output = values.join(); layer.definitionExpression = "CSDNAME IN (" + output + ")";
