How can I implement a pseudo-searchWhenChanged functionality for inputs using a JS button?

Hi guys,

I am looking to create and use a working JS button. I am able to put it in line with my other inputs (https://answers.splunk.com/answers/758599/is-it-possible-to-add-a-button-in-line-with-inputs.html) and am able to have it resubmit searches when tokens are not changed (https://answers.splunk.com/answers/758332/is-it-impossible-to-resubmit-a-dashboard-search-in.html )

However, I'd like a searchWhenChanged="false" functionality for inputs used in conjunction with this button. With my current code, the search still re-runs when the timepicker is updated without the button ever being clicked. I'd like the search to run only on button click.

searchWhenChanged="false" for the inputs is NOT not honored like the bug with the fieldset SubmitButton ( https://answers.splunk.com/answers/742451/searchwhenchangedfalse-not-honored-1.html ), since searchWhenChanged was only meant to be compatible with the fieldset SubmitButton, not a JS button.

Try the following
- store the inputs in their tokens as I assume you are already.
- create hidden text fields for each input but do not change them when you change the value of your inputs
- on selection of the button, assign a hidden text field to now()
- on change of the hidden text field, assign the mapped hidden text fields to the values of your inputs

@tomawest helped me a bunch with this and gave me the idea for my final solution. Basically just use your js to create a "final" token for each "initial" token submitted for each of your inputs.

 require([
     'jquery',
     'splunkjs/mvc',
     'splunkjs/mvc/simplexml/ready!'
 ], function($,mvc){
     var submittedTokens = mvc.Components.get("submitted");
     $('#submit_button').on("click",function(){
         submittedTokens.set("submit_trigger", ""+Math.random());
         submittedTokens.set("my_final_token",submittedTokens.get("my_initial_token"));
     });
 });

This solution is probably better since you don't have to create and edit a separate js file for each of your dashboards like with my answer.
