How can I allow users to set filters dynamically in my Ruby app using JavaScript? For example:
<select id="fltOpt"></select>
<script>
var crit = { tm: 'Noon' };
fetch('/data.json');
</script>

hey, try setting an onchange event on your select so your js object updates on the fly and then re-fetches data. that way, you can send updated filters dynamicaly. works pretty well for me.
Based on my experience, it is often effective to use JavaScript event listeners to capture changes in the select element and then update the filter parameters accordingly. One method involves attaching a change event listener that modifies the filter object and triggers an asynchronous fetch to reload data based on the new criteria. This approach not only provides your users with immediate feedback but also helps keep your code modular and easy to maintain. Additionally, ensuring robust validation on the filter values improves overall reliability and security.
Based on my experience managing similar dynamic filters, I’ve found it useful to structure your JavaScript code so that it cleanly separates collecting input from sending data requests. I modularized my code, which allowed me to update multiple filtering criteria dynamically beyond just one select element. I also built a utility function to sanitize and validate each filter input before triggering the fetch request. This method not only reduces code redundancy but also secures data handling, particularly when expanding to more complex user criteria in future developments.
hey, maybe use a debounce fn on the onchange event so you avoid too many fetch calls. works wonders when users switch filters quickly. cheers!
