In Oracle ADF I am having

<af:resource type="javascript">
var chatSettings = {
   url: "google",
   id: "test"
}
function init(){
...
}
</af:resource>
<af:image id="abc">
<af:clientListener method="init()')" type="click"/>
</af:image>

I want to have url and id as dynamic parameters. I am already defining or have access to those using attributes expression like #{attrs.url} and #{attrs.id} But I am unable to dynamically inject values into the script.

If I use expressions inside af:resource JavaScript block I get the below errors:

Caused by: oracle.jsp.parse.JspParseException:
Error: Encountered deferred syntax #{ in template text. If intended as a literal, escape it or set directive deferredSyntaxAllowedAsLiteral

How can I inject the values into JavaScript block or call the function with parameters so that the variables can be injected into the var block.

You can use af:clientAttribute to pass dynamic parameters. See https://www.jobinesh/2011/03/passing-dynamic-parameters-to-java.html for a sample

You can also run a javascript function inside your ADF java bean : https://cedricleruth/how-to-execute-client-javascript-in-an-adf-java-bean-action/

/*** In YOURJSF.jsf button, or other component that need to execute a javascript on action, add : ****/
<af:commandButton text="ClickMe" id="cb1" actionListener="#{YOURSCOPE.YOURJAVABEAN.clickToExecuteJavascriptAction}"/>
 /*** In YOURJAVABEAN.java class add : ***/
 public void clickToExecuteJavascriptAction(ActionEvent actionEvent) {
  this.executeClientJavascript("console.log('You just clicked : " + actionEvent.getSource() + " ')");
  //Note: if you use a java string value in this function you should escape it to avoid breaking the javascript.
  //Like this : stringValue.replaceAll("[^\\p{L}\\p{Z}]", " ")
 }

//You should put this function in a util java class if you want to use it in multiple bean
public static void executeClientJavascript(String script) {
 FacesContext facesContext = FacesContext.getCurrentInstance();
 ExtendedRenderKitService service = Service.getRenderKitService(facesContext, ExtendedRenderKitService.class);
 service.addScript(facesContext, script);
}
