How to get search results from SplunkJS on click of a button?

[scottsavaresevi]

I'm trying to follow the instructions here, but making the app my own a bit. I have converted my XML dashboard to HTML and am working on editing the JavaScript to make it do something. I have a button that when pressed needs to access the results of search1 (which is the manager for a TableElement) and grab the values in one of the rows. I have this so far:

$("#closeIssue").click(function() {
            // Get the value of the key ID field
            var tokens = mvc.Components.get("default");
            var form_keyid = tokens.get("form.keyid");
            var mySearch = splunkjs.mvc.Components.getInstance("search1");
            console.log( "mysearch:", mySearch );
            var myResults = mySearch.data("results", {count:0});
            console.log( "myresults:", myResults );
            var myrd = myResults.data();
            console.log( "myrd:", myrd );
            var rows = myrd.rows;
            console.log( "rows:", rows );
            return false;
}

The problem is that the "rows" variable is undefined. Looking at the Google Chrome JavaScript console, myResults has data. Looking in the object in _data are the rows I expect to be there. However, when I call myResults.data(), it returns undefined. Any thoughts on how to get the data?

Thanks in advance

I've solved my own problem. The main issue is that I just did not embrace the use of Javascript callbacks. This is just wrong:

var myResults = mySearch.data("results", {count:0});
var myrd = myResults.data();

myResults didn't have the data yet. It runs in the background. The idea being that it may take a while to get the data so don't block the code from running. So I had to set up a callback on the results once the data is loaded:

var myResults = mySearch.data("results", {count:0});
myResults.on( "data", function() {
    var rows = myResults.data().rows;
    // AND SO ON
} );

I would up embedding quite a few callbacks in there, so I have to go in and de-nest all my blocks as predefined functions to make it easier to read.

Looks like the link for the instructions I was trying to follow was not allowed in the post. The instructions I am following are the "Use KV Store with a simple app" tutorial over on dev.splunk.com. In that tutorial they have a delete button that deletes and entry in a collection using the REST API. My button is updating a row and changing one field in the row. But to do that I need to get the current value of the fields in the row out of the search so that I can use include it in the REST call.

Thanks
