Solved: Validate filter value and show error message if va...

sachinbansal · ‎01-20-2020

Hi,

I want to validate the data i enter in data input filter and also want to show error message if user does not enter valid data. Suppose if the input filter value is supposed to be an integer and the user enters a string then I would like show some message indicating to user that you have entered invalid value.

Thanks.

Regards,
Sachin Bansal

Hi

Try this, I had validated with javascript

<form script="validation.js">
  <label>validation</label>
  <fieldset submitButton="true">
    <input type="text" token="integer" id="integer">
      <label>Integer</label>
    </input>
    <input type="text" depends="$hide$" token="show"></input>
  </fieldset>
  <row depends="$form.show$" rejects="$hide$">
    <panel>
      <html>
        <style>
          #error{
          color: red;
          }
        </style>
        <div id="error">

        </div>
      </html>
    </panel>
  </row>
</form>

javascript

require([
"jquery", 
"splunkjs/mvc", 
"splunkjs/mvc/simplexml/ready!"], function($, mvc) {
     var tokens = mvc.Components.get("default");
    $("#submit button").click(function(){
          var tokenValue = tokens.get("integer");
            if (isNaN(tokenValue) || tokenValue < 1) {

                $( "#error" ).text( "Input not valid");
                tokens.set("form.show",true);

              } else{

                  tokens.unset("form.show");
                  $( "#error" ).text("");

              }
    });
});

Updated:

 <form>
   <label>textbox</label>
   <fieldset submitButton="true" autoRun="false">
     <input type="text" token="number" searchWhenChanged="false">
       <label>Enter Integer</label>
       <change>
         <condition match="match(value, &quot;^[0-9]+$&quot;)">
           <unset token="show"></unset>
         </condition>
         <condition match="value== &quot;&quot;">
           <unset token="show"></unset>
         </condition>
         <condition>
           <set token="show"></set>
         </condition>
       </change>
       <initialValue></initialValue>
     </input>
   </fieldset>
   <row depends="$show$">
     <panel>
       <html>
          <style>
            #error{
            color: red;
            }
          </style>
          <div id="error">
           Invalid Input
          </div>
