Condition match on another input's token

Corn · ‎05-31-2018

Hi all,

Is there any way to access the token of a sibling input within the condition-match of another input when handling a change? From what I can tell, trying to access the $token$ of another input gives you some kind of empty/null value.

Basic illustration:

...
<fieldset autoRun="true" submitButton="true">
    <input type="text" token="srch_form">
        <label>Search</label>
        <default></default>
    </input>

    <input type="dropdown" token="srch_dropdown">
        <label>Select dropdown</label>
        <default>option1</default>
        <choice value="option1">option1</choice>
        <choice value="option2">option2</choice>

        <change>
            <condition match="len($srch_form$) == 0">
                <set token="temp_token">srch_form length is 0, dropdown value = $value$</set>
            </condition>
            <condition match="len($srch_form$) > 0">
                <set token="temp_token">srch_form length is greater than 0, dropdown value = $value$</set>
            </condition>
        </change>
    </input>
</fieldset>

I can't seem to hit "len($srch_form$) > 0" regardless of what I type in the first text input, so I'm guessing I'm doing something wrong or the capability isn't there.

Thanks for your help!

Hello.

here is a way to have it functional.

  <init>
    <set token="srch_form_length">0</set>
  </init>
  <fieldset autoRun="true" submitButton="false">
    <input type="text" token="srch_form">
      <label>Search</label>
      <default></default>
      <change>
        <eval token="srch_form_length">len($srch_form$)</eval>
      </change>
    </input>
    <input type="dropdown" token="srch_dropdown">
      <label>Select dropdown</label>
      <default>option1</default>
      <choice value="option1">option1</choice>
      <choice value="option2">option2</choice>
      <change>
        <condition match=" $srch_form_length$ == 0 ">
          <set token="temp_token">srch_form length is 0, dropdown value = $srch_dropdown$</set>
        </condition>
        <condition match=" $srch_form_length$ > 0 ">
          <set token="temp_token">srch_form length is greater than 0, dropdown value = $srch_dropdown$</set>
        </condition>
        <condition match=" 1 > 0">
          <eval token="empty">if(len($srch_form|s$) = 0,"Zero","Non Zero")</eval>
        </condition>
      </change>
    </input>
  </fieldset>

Basically, the length of the first input is computed when it changes, and is set to 0 at init, and this value is used in the match condition.
I could not fix the "len($srch_form$) == 0" case, but I suspect it has to do with this:

@Corn, please try some of the following changes. I am using <eval> to set the token based on conditions you need. (I have also removed Submit Button and added searchWhenChanged to true to have changed value available immediately on changing respective input.

  <fieldset autoRun="true" submitButton="false">
    <input type="text" token="srch_form" searchWhenChanged="true">
      <label>Search</label>
      <default></default>
    </input>
    <input type="dropdown" token="srch_dropdown" searchWhenChanged="true">
      <label>Select dropdown</label>
      <default>option1</default>
      <choice value="option1">option1</choice>
      <choice value="option2">option2</choice>
      <change>
        <eval token="temp_token">if(isnull($srch_form$) OR $srch_form$="","srch_form length is 0, srch_dropdown= ".$value$,"srch_form not empty =".$srch_form$.", srch_dropdown= ".$value$)</eval>
      </change>
    </input>
  </fieldset>
  <row>
    <panel>
      <html>
         <div>srch_form: $srch_form$</div>
         <div>srch_dropdown: $srch_dropdown$</div>
         <div>temp_token: $temp_token$</div>
       </html>
    </panel>
  </row>
