How to stop a workflow through javascript command

Hi All,

I am trying to join two tables

Table 1 : Contains few workflow columns

Table 2 : workflow table

after taking out desired columns (status ==13(Paused)) I need to stop these paused workflows through some external command.

below is the screenshot of my workflow.

after joining both the tables I am taking desired columns in javascript and trying to stop the workflow on the criteria, below is the javascript.

also writing the code below.

{

var strUnactionedWf = "";

var AlertEmail = xtk.queryDef.create(

    <queryDef schema={vars.targetSchema} operation="select">

      <select>

    <node expr="@counter"/>

    <node expr="@internalName"/>

    <node expr="@name"/>

    <node expr="@state"/>

    <node expr="@deliverySentDate"/>    

  </select>

</queryDef>

);

var strUnActionedWorkflow = AlertEmail.ExecuteQuery();

logInfo("Select output "+strUnActionedWorkflow);

for each (var wkf in strUnActionedWorkflow)

{

if (wkf.@state == '13' )

{xtk.workflow.PostEvent;}

}

instance.vars.strUnActionedWorkflow = strUnactionedWf;

logInfo(" outputPausedworkflow "+strUnactionedWf);

}
