Changing multiple tables in SimpleXML using SplunkJS

pgullette — Fri, 28 Mar 2014 01:15:59 GMT

I need to be able to modify the behavior of any number of tables on a dashboard created with SimpleXML. I have my custom JavaScript added to the page and running properly. I am using mvc.Components.getInstances() to get a full list of all components on the page, and this is working as expected. Also, I'm using splunkjs/mvc/simplexml/ready! as a dependency so that my JavaScript executes after everything is ready. And I should mention that I'm using getInstances() instead of getInstance() because I want the behavior to be generic for any number of tables.

Here's where the problem is. When I iterate through my instances returned by getInstances(), certain properties are not yet available. Specifically, since I am trying to manipulate tables on the dashboard, I am unable to access the visualization member as it's NULL at the time my code is running. What is the proper way to manipulate a SimpleXML table after it's fully loaded? And another related question, is there an easy way to determine if an object returned by getInstances() is specifically a table without looking for a specific property?

Thanks for any help.

Curious to see if you figured out a solution to this problem.

Thanks,

var libs = [
    "jquery",
    "splunkjs/mvc",
    "splunkjs/mvc/simplexml/element/table",
    "splunkjs/mvc/simplexml/ready!",
];

require(libs, function ($, mvc, TableElement) {
    "use strict";

    $.each(mvc.Components.getInstances(), function (i, view) {
        /**
         *  @author Marco Sulla (marcosullaroma@gmail.com)
         *  @date Jan 31, 2015
         */

        if (view instanceof TableElement) {
            view.getVisualization(function (view) {
                view.on("rendered", function () {
                    console.log(view);
                 });
            });
        }
    });
});

Did you find a solution? I would also like to address all Tables (unknown ids).

So we started off running a loop finding ".table.splunk-view".each". We were then able to get the attribute "id" of each instance. From there we went about it in a similar manner as Marco's solution below by plugging in the id we gathered in the previous step.

Hope this helps!

It does (that's exactly what I am trying to do), but it would be great if you could share that snippet of code 🙂
