How to retrieve element from array in a jelly tag

[mahudg2]

Sorry I understand this might be a very simple question, but despite my research I've hit a wall here. Here is my code below

<g:evaluate>
var gr = new GlideRecord('u_uksystemstatus');
var statuses = new Array();
var servicestates = new Array();
var i = 0;
gr.query();
while(gr.next())
{
statuses[i] = gr.u_servicetitle.toString();
servicestates[i] = gr.u_servicestate.toString();
i = i + 1;
}
</g:evaluate>

<j:forEach var="jvar_word" items="${words}">
   <p>${jvar_word}</p>
</j:forEach>
<j:forEach var="jvar_status" items="${statuses}">
                         <li>${jvar_status} ${servicestates}</li>
</j:forEach>
</j:jelly>

My goal   is to display each status in the statuses array with the corresponding service state, but I'm not sure how to retrieve a specific element in an array that corresponds to the element that is being retrieved in the <j:forEach> tag. Does anyone have any ideas?

Thanks!

I'm doing something similar and fail too...

             <g:evaluate var="jvar_ship_to_array" jelly="true" object="true">

               var SysIds2 = jelly.jvar_mrl_ids;

               var shiptoGr = new GlideRecord('proc_po_item');

               shiptoGr.addQuery('sys_id','IN',SysIds2);

               shiptoGr.query();

               var shipto = [];

               while (shiptoGr.next()){

                 var objShipto = new Object();

                 var getId = shiptoGr.purchase_order.ship_to.getValue();

                 var getDisplay = shiptoGr.purchase_order.ship_to.getDisplayValue();

                 objShipto.sysid = getId;

                 objShipto.label = getDisplay;

                 shipto.push(objShipto);

               }

               var test = shipto[0];

               shipto;

             </g:evaluate>



             ${test.sysid}





             <j:forEach items="${jvar_ship_to_array}" var="jvar_shipto">

               ${jvar_shipto.sysid}

               ${jvar_shipto.label}

             </j:forEach>

Strange is that the ${test.sysid} returns the value properly... <j:forEach> seems not to work, or what am I doing wrong?

I found the solution in this discussion:

Jelly: Over and Over Again...

You have actually to evaluate each object value as Jelly seems not to be capable of doing so. See line 19 and 21 below

             <g:evaluate var="jvar_ship_to_array" jelly="true" object="true">

               var SysIds2 = jelly.jvar_mrl_ids;

               var shiptoGr = new GlideRecord('proc_po_item');

               shiptoGr.addQuery('sys_id','IN',SysIds2);

               shiptoGr.query();

               var shipto = [];

               while (shiptoGr.next()){

                 var objShipto = new Object();

                 var getId = shiptoGr.purchase_order.ship_to;

                 var getDisplay = shiptoGr.purchase_order.ship_to.getDisplayValue();

                 objShipto.sysid = getId;

                 objShipto.label = getDisplay;

                 shipto.push(objShipto);

               }

               shipto;

             </g:evaluate>



               <j:forEach items="${jvar_ship_to_array}" var="jvar_shipto">

                   <g:evaluate var="jvar_shipto_id" jelly="true" expression="var shiptoSysid = jelly.jvar_shipto.sysid; shiptoSysid;"/>

                   ${jvar_shipto_id}

                   <g:evaluate var="jvar_shipto_display" jelly="true" expression="var shiptoDisplay = jelly.jvar_shipto.label; shiptoDisplay;"/>

                   ${jvar_shipto_display}

               </j:forEach>

All,

I am also having trouble.   I copied a functioning <j:forEach from another UI Page but it doesn't work in the code below.   I have had to hard code the <option> tags which will make this a single purpose UI Page unless I can get it resolved.

<div id="divContainer" class="container">
<g:ui_form onsubmit="return invokePromptCallBack();">
   <g2:evaluate>
   var title = "${RP.getWindowProperties().get('title')}";
   title =   new GlideStringUtil().unEscapeHTML(title);
   var message1 = "${RP.getWindowProperties().get('message1')}";
   message1 =   new GlideStringUtil().unEscapeHTML(message1);
   var message2 = "${RP.getWindowProperties().get('message2')}";
   message2 =   new GlideStringUtil().unEscapeHTML(message2);
   var question = "${RP.getWindowProperties().get('question')}";
   question =   new GlideStringUtil().unEscapeHTML(question);
   var useNone = "${RP.getWindowProperties().get('useNone')}";
   var options = "${RP.getWindowProperties().get('options')}";
   options = options.toString();
   var arrOptions = options.split(',');
   //arrOptions = ['No', 'Yes'];
   </g2:evaluate>
   <h1>$[title]</h1>
   <div class="message">$[message1]</div>
   <div class="message">
   <j:forEach items="${arrOptions}" var="jvar_option" indexVar="jvar_idx">
   <span>${jvar_option}</span>
   </j:forEach>
</div>
   <div class="question">
   <label for="question1"><g:no_escape>$[question]</g:no_escape></label>$[SP]$[SP]
   <select id="question1">
   <j2:if test="$[useNone == 'Yes']">
   <option value="" id="option_none"> - None - </option>
   </j2:if>
   <j:forEach items="${arrOptions}" var="jvar_option" indexVar="jvar_idx">
   <option value="${jvar_option}" id="option_${jvar_option}">${jvar_option}</option>
   </j:forEach>
   <option value="No" id="option_No" selected="true">No</option>
   <option value="Yes" id="option_Yes">Yes</option>
   </select>
   </div>
   <div class="message">$[message2]</div>
   <table border="0" width="100%">
   <tr>
   <g:macro 
     ok="actionOK()" 
     cancel="GlideDialogWindow.prototype.locate(this).destroy(); return false" 
     ok_id="ok_button" 
     cancel_id="cancel_button" 
     ok_type="submit" 
     cancel_type="submit" 
   />

   <td class="dialog_buttons">
   <g:dialog_button 
   id="${jvar_ok_id}" 
   type="button" 
   onclick="invokePromptCallBack('ok');" 
   style="width: 5em;">${gs.getMessage('OK')}</g:dialog_button>
   </td>
   <td class="dialog_buttons">
   <g:dialog_button 
   id="${jvar_ok_id}" 
   type="button" 
   onclick="invokePromptCallBack('cancel')" 
   style="width: 5em;">${gs.getMessage('Cancel')}</g:dialog_button>
   </td>
   </tr>
   </table>
</g:ui_form>
</div>

Any help would be greatly appreciated.

Respectfully,

Robert

Hey, Robert

arrOptions is being defined in the second phase - indicated by the 2 in g2:evaluate.

Your j:forEach is running in first phase which will be why it isn't working (assuming there are no other issues).

Update your j:forEach to be j2:forEach and it should work.

Best regards,

James
