Multiselect clear selections

mwdbhyat — Mon, 17 Feb 2020 13:33:44 GMT

Hi there,

How can I clear all of the selected options in a multiselect with one click? Is there a way to make it "reset" the entire box if I want to?

Thanks!

@mwdbhyat

You have to just unset that input.

Like, if XML

<unset token="multiselect_token"></unset>

Ref: https://conf.splunk.com/files/2017/slides/tokens-in-splunk-web-framework-use-abuse-and-incantations.pdf

Using Javascript:

 var defaultTokenModelun = mvc.Components.getInstance('default', {create: true});
 var submittedTokenModelun = mvc.Components.getInstance('submitted', {create: true});

 function unsetToken(name) {
     defaultTokenModelun.unset(name);
     submittedTokenModelun.unset(name);
 }

 $(document).on("click", "#ButtonId", function() {
         unsetToken("multiselect_token")
 });

Try this

<form script="reset.js">
  <label>resetbutton</label>
  <fieldset submitButton="false">
    <input type="multiselect" token="field1">
      <label>field1</label>
      <choice value="one">One</choice>
      <choice value="two">Two</choice>
      <choice value="three">Three</choice>
    </input>
    <html>
      <input type="button" id="reset" value="Reset"/>
    </html>
  </fieldset>
</form>

Javascript:

require([
     'jquery',
     'splunkjs/mvc',
     'splunkjs/mvc/simplexml/ready!'
 ], function($, mvc) {
      var tokens = mvc.Components.get("default");
     $("#reset").click(function(){
      tokens.unset("form.field1");
    });

 });
