GenerateLookup

Read Fields via Ajax Request. We use it to do Calculations based on entry fields or lookup descriptions and so on.

• generateLookup : the Element name to use to generate the Event Handler
• actionBefore : JScript that is executed before the lookup is done
• event : the event for which the Event Handler is installed
  • name : name of the Javascript event, 'click','change','blur',..
  • elementname : Name of the entry field the Event Handler is attached to, OR
  • element : ID of the entry field the Event Handler is attached to
  • prototypeEvent= could be used to observe a customized prototype event [1] e.g.: "{@name}:" (DON'T FORGAT THE : AT THE END)
• requestname : the Web-Request to execute
• fill : Parameter(s) for the WebRequest
  • from : name of the field the parameter value comes from, OR
  • fromid : id of a field the parameter value comes from, OR
  • fromvalue : a fix value that should be used as parameter value
  • to : name of the parameter
• return : the response field(s) that are used
  • from : name of the response field
  • to : name of the field in the webpage to receive the response value

Example

 <xsl:template name="postFieldException">
  <xsl:choose>
   <xsl:when test="@name='ATOFAC'">
    <a href="#" id="get_ATOFAC" style="margin-left:5px;">nachlesen</a>
              
    <generateLookup>
     <actionBefore>console.log('Hi!');</actionBefore>
     <event name="click" element="get_ATOFAC"/>
     <requestname>MyEntitySFXML</requestname>
     <fill from="ATOfAT" to="KeyValue"/>
     <fill fromvalue="aFixValue" to="anInputField"/>
     <return from="ActSub" to="ActSub"/>
     <return from="AcBody" to="AcBody"/>
    </generateLookup>
         
   </xsl:when>
  </xsl:choose>
 </xsl:template>
 <!--within the global "F4" it is slightly different cause it is defined at the second filter level -->
 <xsl:template name="F4">
  <xsl:choose>
    <xsl:when test="contains(@impl,'ProID')">
     <xsl:call-template name="generateLookup">
       <xsl:with-param name="param">
         <event name="change" element="{@hid}"/>
	 <requestname>ProjectSFXML</requestname>
	 <fill from="ProID" to="ProjectID"/>
         <return from="ProDesc" to="ProDesc"/>
       </xsl:with-param>
     </xsl:call-template>
   </xsl:when>
  </xsl:choose>
 </xsl:template>

As a Plex base function you could use a SingleFetch (e.g. MyEntity.XML_Intern.BaseServices.SingleFetch) when the base is a Dictionary function you should use "aaGetAJAXDictXML.xsl" as the filter XSLT
