How can I refresh splunk search in a dashboard only one time after it is loaded?

[Razziat]

I have a dashboard using a js script. The issue is that the js sctipt is loaded a the beginning. Because the method which using the $(document).ready is not working for an unknown reason, I had the idea to refresh the dashboard or just the search that is usig the js script. But the only solutions that I found are refreshing every X time. 
Is there a solution to refresh only one time a dashboard or just a search after the loading has ended ?
Thanks in advance !

Would something like this work

<dashboard version="1.1">
  <label>Delayed</label>
  <row>
    <panel>
      <table>
        <search>
          <query>| makeresults
| eval trigger=$trigger$
| fields - trigger
| eval message="Table loaded at ".strftime(now(),"%F %T")</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
        </search>
        <option name="drilldown">none</option>
      </table>
    </panel>
  </row>
  <row depends="$donotshow$">
    <panel>
      <table>
        <search>
          <query>| makeresults count=10000
| eval random=random()%100</query>
          <earliest>-24h@h</earliest>
          <latest>now</latest>
          <done>
            <set token="trigger">go</set>
          </done>
        </search>
        <option name="drilldown">none</option>
      </table>
    </panel>
  </row>
</dashboard>

Essentially, the main search(es) will wait for a token to be defined, which is only defined when the search in the last panel (which I have hidden in this instance) has completed. The search in my last panel takes a little time just to demonstrate the effect.

As I undertstand your code, this gives the time between start of dashboard loading and end of search loading. I tried with mine using your code and It appears that it is done instantly. The problem here is that the js script is loaded before anything. Therefore, the code of the script is not applied on the search even though it is loaded instantly.

Bearing in mind that I am not an expert on javascript, but could you trigger your script on the basis of an input changing. You might be able to hide the input in a similar way using the depends attribute, as set the value of the input $form.token$ in the done handler for either a dummy search or indeed your main search?

I see what you have in mind. Unfortunately I don't think that it will work in my case. Also, it will be easier to create a button that can refresh a pannel by clicking on it. Or a button that rerun the js script load in the xml file.
If you have any other idea I will be happy to read it.
However thanks for your time.
