1.  Use the provided JavaScript function named HandleWAMEvent().

     This This function can be called the same way HandleEvent() function is called now.

2.  The parameters are HandleWAMEvent(WAM, Webroutine, TechServ, Form, Target, actionRequest, Partition, Language, optSessionKey, optDebugMode, "ASURNAME", "ASTDRENTRY", ...), a variable number of parameters can be passed for fields, the values of which are to be passed to the Webroutine. It is important to provide a single character prefix before the field name. The prefix is A for Alphanumeric, P for Packed and S for Signed fields, or Q for RDMLX fields. Although this prefix is not required when passing field values to a WAM WEBROUTINE, it is required to access the form field value, as well as being more consistent with HandleWebEvent() JavaScript function semantics.
     

The parameters of HandleWAMEvent are:

WAM

The name of the target WAM.

Webroutine

The name of the target WEBROUTINE.

TechServ

The Technology Service to use, can be null for default LANSA XHTML Technology Service.

Form

The form HTML object to get field values for submit from, e.g. document.MYFORM for a form with "MYFORM" name, can be null for default LANSA form.

Target

The target iframe, frame or window where the result of navigation will be displayed, null to navigate to a new page.

actionRequest

If left null, is the default "cgi-bin/lansaweb" action request.

Partition

The partition to execute the WAM from.

Language

The language under which the WAM will execute.

optSessionKey

Can optionally pass the session key, if the SessionKeyMethod is URL, otherwise null.

optDebugMode

Can pass the debug url keyword to allow debugging of the WAM, otherwise null.

2.  Replace <your wam name> and <your webroutine name> with the appropriate names.

     Note Note that the WAM must exist in the same partition and will execute in the same language using the default LANSA:XHTML technology service. Otherwise, change the values of fields #techserv, #currlang and #partition accordingly.

...

5.  Create a new page and paste this code:

...

     <button onclick="return HandleWAMEvent('

...

<RDML MERGE="WAMNAME">', '

...

<RDML MERGE="WEBRNAME">',

...

 '

...

<RDML MERGE="TECHSERV">',

...

 null,

...

 '

...

<RDML MERGE="TARGET">',

...

 null,

...

 '

...

<RDML MERGE="PARTITION">',

...

 '

...

<RDML MERGE="CURRLANG">',

...

 null,

...

 null,

...

 'ASURNAME',

...

 'ASTDRENTRY'

...

 )">Search</button>
