How to connect to CRX from Javascript?

With Client side javascript it is not possible. You can use server side java script (Ecma). Samples below

* Create a file /apps/geometrixx/components/page/test.ecma with content as [1].

* Which ever component or a page you want to use call as [2] with/without absolute url.

[1]

var resourceResolverFactory = sling.getService(Packages.org.apache.sling.api.resource.ResourceResolverFactory);

var authInfo = new java.util.HashMap()

authInfo.put("user.name","admin")

authInfo.put("user.password",new java.lang.String("admin").toCharArray())

var resourceResolver = resourceResolverFactory.getResourceResolver(authInfo)

out.println(resourceResolver.getResource("/content/geometrixx/en") );

[2] <cq:include script="/apps/geometrixx/components/page/test.ecma"/>

You can do this with a custom renderer in a JSP as well, place a JSP in the component with a new custom render e.g. json.jsp and invoke the  content (created with the component) URL  by sufixing .json in the URL. From your script call the .json URL (which returns the output as per what you write in the custom json renderer) and process it. For example there many json renderes available out of the box see one of the json renderer (libs/cq/workflow/components/inbox/steps/json.jsp) which returns thea json string. Hope this helps!

Hello Veena,

If you want to dynamically modify nodes data to dialog properties (widget/xtype) and if it is only for specific scenario the i would prefer to write listener (loadcontent or beforeloalcontent ) on dialog (tabpanen/panel).

Please refer http://dev.day.com/docs/en/cq/current/widgets-api/index.html (to know about available events for each xtypes)

You can refer below as example function to travel through nodes and getting/setting property of your dialog

function(filed, record, path) {

  var nodeField="filed name from any node you want to capture";

var targetField="field you want to set on dialog (panel/tabpanel)";

  var pathParts=path.split('/');

  pathParts.pop();  // use this line to travel parent node

  var jcrContentPath=pathParts.join('/');

  var response = CQ.utils.HTTP.get(jcrContentPath +'.json');

  eval('var data ='+response.responseText);

  record.set(targetField, data[nodeField]);  //this line will help to get and set value of property to your dialog or wherever you want to set.

  return true;

}

I hope it will help you. Let me know if you need more information.

Hello Veena,

I think the same i mentioned (write listener 'loadcontent'). You have to do some debug and adjust the code as per requirement but i hope it will suits.

Line pathParts.pop();  // use this line to travel parent node will help you to travel through node in parent but for sibling nodes you have to do some debuggin better refer

http://dev.day.com/docs/en/cq/current/widgets-api/index.html to check out all other public methods availabe for that resource.

once you find the exact node using above now you can use

var response = CQ.utils.HTTP.get(jcrContentPath +'.json');

  eval('var data ='+response.responseText);

to get the node out of that path and then you can use

data[nodeField]

to get out the value of required field associated to that node and then you can set it to your actual resource (means dialog panel/tabpanel) using below

  record.set(targetField, data[nodeField]);

i hope this clarifies you bit more. But as i mentioned you have to play with this code to make it work according to your requirement.

Thanks,

Pawan
