if condition in UI page jelly script

[samadam]

I have two variables, one being set from syspam value and other from a query. I want to use them in a query based on if there is a value passed as parameter or if null use the value set in the g:evaluate.

This only works if syspam variable is populated. Using the test condition the value gets set but in the query it doesn't work. I tried to use "jvar_minc" insated of '${jvar_minc}' but this only works for one condition. How can I get this working. Is there a way to have if condition in g:evaluate?

<g:evaluate jelly="true">

  <j:set var="jvar_inc" value="${RP.getParameterValue('sysparm_inc')}" />

  </g:evaluate>

<g:evaluate jelly="true">

  var currentval = new GlideRecord('u_temp'); .addEncodedQuery('u_start_date&lt;=javascript:gs.daysAgoEnd(0)^u_end_date&gt;=javascript:gs.daysAgoStart(0)');

currntval.query();

currentval.next();

  var jvar_minc = currentval.q_val;

  </g:evaluate>

<j:if test="${!empty(jvar_inc)}">

  <j:set var="jvar_minc" value="${jvar_inc}" />

  </j:if>

  <g:evaluate jelly="true">

  var inc = new GlideRecord('u_temp_table');

  inc.addQuery('u_inc_name', '${jvar_minc}');

  inc.addQuery('u_id', '${jvar_id}');

  inc.query();

  </g:evaluate>

when i print the values they come up right, its in the query it doesn't do the right evaluation.

Hi Sam,

You don't need a g:evaluate tag around the first j:set. g:evaluate is for running JavaScript. Also, when you use jelly="true", it says "I'm going to use a copy of the jelly variables", but you're not using them. Best practice is to avoid using ${variable} calls inside g:evaluate tags. You're half way there with jelly="true", but didn't use them. Finally, you had a hanging '.addEncodedQuery()" call with no object. Where did jvar_id come from? It is used in the second g:evaluate statement, but I don't see it set anywhere. Here's a cleaned up version of your script.

  <j:set var="jvar_inc" value="${RP.getParameterValue('sysparm_inc')}" />

<g:evaluate var="jvar_minc" jelly="true">

  var currentval = new GlideRecord('u_temp');

  currentval.addEncodedQuery('u_start_date&lt;=javascript:gs.daysAgoEnd(0)^u_end_date&gt;=javascript:gs.daysAgoStart(0)');

  currntval.query();

  currentval.next();

  currentval.q_val;

  </g:evaluate>

<j:if test="${!empty(jvar_inc)}">

  <j:set var="jvar_minc" value="${jvar_inc}" />

  </j:if>

  <g:evaluate jelly="true">

  var inc = new GlideRecord('u_temp_table');

  inc.addQuery('u_inc_name', jelly.var_minc);

  inc.addQuery('u_id', jelly.jvar_id); // What is jvar_id???

  inc.query();

  </g:evaluate>

Thanks a lot. Got it working with your suggestions.

Chuck,

I know you're a super busy guy, but I feel like this is related in that I just don't know how to set/access the variable properly.  If you have a minute can you give me some guidance on what I'm trying to do here?

I'm trying to pull in a value from my UI Action - stored via this code
dialog.setPreference('ei_sys_id', sys_id);

Into my UI Page - I have tried using multiple variations of g:evaluate an j:set to get the sys_id to use to query the table and build the array I need to print and nothing is working - but then again I am blindly stabbing in the dark, because I know very little about jelly.

Essentially what I want to is take that value from the UI action above and store it in a variable that would be referenced where <insertvariablehere> is in the snippet below.

<g:evaluate var="jvar_forecasts" object="true" jelly="true">
var arrForecasts = [];
var grForecasts = new GlideRecord("u_ehs_forecasts");
grForecasts.addEncodedQuery('u_forecast_parent=' + <insertvariablehere>)};
grForecasts.query();

Thanks,
Shannon

I found several examples of getPreference in UI pages. It appears to be accessed in JavaScript like this (from the catalog_find UI page...

   <g:evaluate var="jvar_theme">
		var theme = gs.getPreference('glide.css.theme.ui16');
		if (null == theme){
			var company = gs.getUser().getCompanyRecord();
			if (null != company)
				theme = company.getValue("theme");
		}
		theme;
   </g:evaluate>
