[alicebot-style] Assign a value to a predicate with javascript

[Anne Kootstra]

It seems to me that this isn't a general AIML style question but one that is
particular to the Program D engine. Perhaps you can ask your question on
Alicebot.org Developer mailing list but there is also a specific Program D
mailing list at www.aitools.org <http://www.aitools.org/> .

Onderwerp: [alicebot-style] Assign a value to a predicate with javascript

 

Hi everybody,

 

I have a problem that i can't solve using Program D. This problem involves
predicates and the <javascript> tag.

 

What I would like to do is to pass the value of a predicate to a javascript
function, manipulate this value and get it back in another predicate.

 

I post an example below:

 

<category>
 <pattern>PRINT *</pattern>
 <template>
  <think>
   <set name="x"><star/></set>
   <set name="y">
    <javascript>
     function replacestring(s){

     var x=s;
     x.replace(/&lt;/i, " lt ");
     x.replace(/&gt;/i, " gt ");

     return x; }

     replacestring('<get name="x"/>');
    </javascript>
   </set>
  </think>
 </template>
</category>

In this example I get a value from the user and put it in a predicate called
x and after that I try to put the value of y in a predicate called y, after
having replaced all the < and > of the predicate with the values lt and gt.

 

In this example I don't get any error from the Javascript interpreter and I
think that the code is quite correct and it should work, but at the end the
predicate y is empty.

 

I think that this isn't the correct way to assign values from the javascript
but, if I can't use the return, how can I assign the value?

 

Thank you everybody for your help.

 

Ale
