How to retrieve the value of a token in JavaScript...

danillopavan · ‎01-23-2018

Hello all,

In the HTML I have included a SEARCH and set the data result in a TOKEN through the below:

var search1 = new SearchManager({
            "id": "search1",
            "earliest_time": "-15m@m",
            "sample_ratio": null,
            "cancelOnUnload": true,
            "latest_time": "now",
            "search": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
            "status_buckets": 0,
            "app": utils.getCurrentApp(),
            "auto_cancel": 90,
            "preview": true,
            "runWhenTimeIsUndefined": false
        }, {tokens: true, tokenNamespace: "submitted"});


    new SearchEventHandler({
        managerid: "search1",
        event: "finalized",
        conditions: [
            {
                attr: "any",
                value: "*",
                actions: [
                    {"type": "set", "token": "status_execucao", "value": "$result.data_range$"}
                ]
            }
        ]
    });

Now I am trying to retrieve the value of this token in the JS via jQuery but am not able to do that.

Which command should I use to retrieve the token via jQuery?

$('#status_execucao').get()?

Many thanks and regards,
Danillo Pavan

@danillopavan, first off, which version of Splunk are you on?

finalized search event handler was used in Splunk versions 6.4 and before. Post 6.5 you should use done instead:

  event: "done",

Option 1: If the token status_execucao is already set by the time your JavaScript code tries to access the token, then depending on token model (default or submitted) you can use Splunk JS stack to get and set tokens (http://dev.splunk.com/view/webframework-developapps/SP-CAAAEW3).

// Access the "default" token model
var defaultTokenModel = mvc.Components.get("default");

// Retrieve the value of a token $status_execucao$
var tokenValue = defaultTokenModel.get("status_execucao");

Option 2: You can use Splunk JS stack to get the token value in JavaScript using token change() event (http://dev.splunk.com/view/SP-CAAAEW4):

    // Access the "default" token model
    var defaultTokenModel = mvc.Components.get("default");
    defaultTokenModel.on("change:status_execucao", function(newTokenName, status_execucao, options) {
        if(status_execucao!==undefined && status_execucao!=="$result.data_range$"){
            console.log("status_execucao: ",status_execucao);
        }
    });

Please try out and confirm!

Hello Niketnilay,

thanks for your support. I have tried to use the commands however it is appearing the error message:

Uncaught TypeError: Cannot read property 'get' of undefined

I have included the below dependencies:

require(['jquery','splunkjs/mvc','backbone'], function($) {

and the commands:

var mvc = require("splunkjs/mvc");
var defaultTokenModel = mvc.Components.get("default");

@danillopavan, are you using HTML dashboard or Simple XML JavaScript extension? As per your question it seemed like you are using HTML Dashboard which implies mvc should already be included.

Here is one of my previous answers for Option 1: https://answers.splunk.com/answers/580205/how-to-get-search-idjobsid-from-xml-dashboard-in-j.html

Hi, yes I am using HTML with jQuery (splunk version 6.4). My HTML is similar to the one that you posted above.

Not sure if the query is running correctly. Is there any way to ensure the value of the token?

About the java script file, I need to retrieve the token value to display the value in a element that I have created using jquery/bootstrap...

How can I get it?

var status_execucao = document.getElementById('status_execucao');

Not working...

danillopavan · ‎01-26-2018

Hello Niketnilay,

Just noted that when I use "defaultTokenModel = mvc.Components.getInstance('submitted')", I got the error in the next line "defaultTokenModel.on("change:status_execucao", function(newTokenName, status_execucao, options)" because the variable defaultTokenModel is not yet setted.

And when I use "defaultTokenModel = mvc.Components.getInstance('default')", i am not facing the issue however the tokens are not yet setted, so i am not able to retrieve the values.

Probably it is happening because there is not enough time to load this code while the search is not yet finished.

How I can do to load continue the execution of the code only when the search is finished?

Thanks and regards,
Danillo Pavan

Hello Niketnilay, any help? Thanks!!

niketn · ‎03-12-2018

Hi @danilliopavan, sorry I missed seeing your questions... If you are on Splunk 6.4 you will not have done or progress event handler, instead you will have preview and finalized event handlers. i.e. instead of event: "done", you should have the following:

    event: "finalized",

Refer to Search Event Handler documentation in Splunk Docs for 6.4.7: https://docs.splunk.com/Documentation/Splunk/6.4.7/Viz/EventHandlerReference#preview

Also refer to following answer where we had to do several trials and errors to get the working HTML dashboard code from Simple XML: https://answers.splunk.com/answers/614832/how-to-add-icon-to-a-panel-instead-of-table-so-the.html
