How do I read the values from a dashboard table into a JavaScript object using JavaScript?

[andrewtrobec]

Hello!

My objective is to read the values of a Spunk table visualization from a dashboard into a JavaScript object for further processing.  I'm not sure what object yet, but my main issue lies with iterating through the table and extracting the cell values.

Can anybody provide some sample JS code for identifying the table object and interating through its values?

Thanks!

I would probably have done search parsing through Python but it can be done using Javascript.

Create a blocking search which will wait until the search in finished then reference the job object results field.  The results can then be mapped to a list or dictionary for use.  Once you have completed the tasks associated with the search values it can be rendered back to the dashboard.

require([],
function()  {
    var splunkWebHttp = new splunkjs.SplunkWebHttp();
    var service = new splunkjs.Service(splunkWebHttp);
    var searchQuery = "search index=_internal | head 5";
    var searchParams = {exec_mode: "blocking"};
    service.search(
        searchQuery,
        searchParams,

        function(err, job) {
            job.fetch(function(err){
            console.log("Job ID: " + job.sid);
            console.log("Max Results: " + job.properties().resultCount);

            // iterate results by row
            job.results({}, function(err, results) {
                var fields = results.fields;
                var rows = results.rows;
                for(var i = 0; i < rows.length; i++) {
                    var values = rows[i];
                    console.log("Row " + i + ": ");
                    for(var j = 0; j < values.length; j++) {
                        var field = fields[j];
                        var value = values[j];
                        console.log(" " + field + ": " + value);
                    }
                }
            })
            });
        });
})
