Hello all! I'm developing a custom dashlet for Alfresco share. I've seen many examples and made several simple projects, but now I need something more complicated. I have a project (it's a set of files). Some of them contain JS code.
My idea is to make a query to a webscript in <Project home>/config/alfresco/site-webscripts/org/alfresco/components/dashlets/mydashlet.get.js, store its result in model variable and then access it in <Project home>/source/web/components/dashlets/mydashlet.js
I try to do it like this:
1) <Project home>/config/alfresco/site-webscripts/org/alfresco/components/dashlets/mydashlet.get.js

function main()
{
      var json = remote.call("/api/task-instances?state=completed");
         if (json.status == 200)
         {
            data = eval('(' + json + ')');
         }
    
      model.data = data.data;
}
main();
‍‍‍‍‍‍‍‍‍‍‍‍‍

2)<Project home>/source/web/components/dashlets/mydashlet.js

…
loadData: function MyDashlet_loadData()
      {
         alert(model.data);
      }
…
‍‍‍‍‍‍‍‍

Nothing happens and I don't see my message… Any help or ideas really appreciated: I've been trying to do it for a week…
P.S. In my <Project home>/config/alfresco/site-webscripts/org/alfresco/components/dashlets/mydashlet.get.html.ftl I have access to ${data} from my model.data

Hello,

Rember that there are two types of webscripts, the first type is to retrieve data vía REST, or webscripts for show information (for example dashlets). The behaivor is based in MVC pattern, in this case your Controller could be a js file or a Java class to access the Model. Your view is in freemarker. There is good information about webscripts and MVC pattern in the Wiki and Web.

But If you have a webscript to retrieve data, and I guess for your code that the response is in JSON format, I recomend you to do the next in your freemarker template:

Alfresco.util.Ajax.request(
         {
            method: "POST",
            url: "/alfresco/service/com/someservice",
            dataObj:
            {
               var1:'value1',
               var2:'value2',
            },
             successCallback:
            {
                fn: function dlA_onActionDetails_refreshSuccess(response)
                    {
                  var rawResponse = response.serverResponse.responseText+"";
                  var obj = eval('(' + rawResponse + ')');
                  //to do something with this object…
               }        
            }
         });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

After that you can play with that object as you want!

You can access vía GET or POST, but it depends of the definition of your webscript.

Good Luck
