Shell scripts from WebUI - is it possible, advice, ideas

Rename the file to end with .js. Refer to it as /ext/results.js

Or you can use .htm.

That fixed it but led me to my next hurdle.

When I try to include showloading() and document.form.submit, to allow for the script to run / complete when the service-event is triggered, the returned results.js isn't displayed in the textarea. But if I remove show loading() and document.form.submit the results do show. Note - I'm not actually running the triggered service at this point, I have a results.js populated with the output of one my script already.

Below is the onclick function that gets called when the Run button is hit.
- What do I need to do to get the results to display after a delay period?
- I the showloading() + document.form.submit() combination the proper way to allow for a delay?
- Any suggestions or pointers much appreciated

function runScript(){
        /* Retrieve value from input fields, and store in object */
        custom_settings.scriptsui_script = "/jffs/addons/scriptsui/mysript.sh";

        /* Store object as a string in the amng_custom hidden input field */
        document.getElementById('amng_custom').value = JSON.stringify(custom_settings);

        /* Apply */
        showLoading()
        document.form.submit();
        get_results_data();

}

There are a few examples of "submitting" a request to trigger the service-event without getting into the whole "Please wait..." overlay.

See if you can make sense of the cake_status_check hidden form and submit_refresh_status() function in CakeQoS-Merlin.

You essentially pass the action for service-event to run via the action_script ASP variable and then trigger the ajax check with a suitable timeout based on how long you think it will take for the response to be ready in /www/ext/.

The main page doesn't get blocked or refreshed until the result is available. If you need to use the custom_settings to transfer your script name, I don't recall if you need to submit the main form in order for httpd to process that variable or not.

Otherwise, when your page refreshes after submit, you need something in the initial() function to load that file under /ext/ into your text field. Maybe you should post the full code somewhere for review. Or study how the System Log page loads the initial syslog files and then refreshes every 3 seconds. It uses special commands for fetching the syslog data, but the initial load through ajax calls is still there.

Thank you @dave14305 for all the pointers, feedback, and references. I finally have a working prototype based on the Third Party API.

As time permits and if there’s interest, I’ll provide a write of the prototype.
