Call JAVA method from Jelly

[Tomasz Szandała]

Greetings,

I'm working on jenkins plugin nad now encountered a problem:

I've inserted a picture to my GUI (using jelly) and now I want to invoke method on click.

Best would be if I can pass an argument to it, for example:

my method:

public void setOwner(String owner)

and I have picture:

<img src="/plugin/PluginForJenkins/images/claim.png"/>

how can I make this picture clickable?

wrap it in a <a> or add a javascript onclick event handler

Thank you, but could you, please, give me an example of using <a> tag? I need to pass a string argument to it.

Spent whole day today working on it, but... failed in it

Roughly like so:

In YourBackendClass.java

    @JavaScriptMethod

    public void setOwner(String owner) {

      this.owner = owner;

    }

In the.jelly

    <st:bind var="${theInstanceOfYourBackendClass}" var="backend"/>

    <script>

        function setOwner(owner) {

          backend.setOwner(owner, function(t) {

            //Handle the response

          });

        }

    </script>

   ....

   <img src="/plugin/PluginForJenkins/images/claim.png" onClick="setOwner('theOwner')"/>

OK it works, I solved the problem. Odd: it was in deleting cookies O_o

Thanks for help ;-)

So I have Java class: PublishingAction:

public class PublishingAction implements Action, ProminentProjectAction {
...
@JavaScriptMethod
 public void lockMismatch(int hashCode){
 
  for(MismatchesContainer mc: allMismatches){
   for(Mismatch msm: mc.getMismatchesList()){
    if(msm.hashCode()==hashCode){
     msm.lock("Claimer", "reason");
    }
   }
  }
}

And in jelly:

 <script>
      var myAction= <st:bind value="${it}" />
      function lockMismatch(mismatchHash) {
             myAction.lockMismatch(mismatchHash);
       }
 </script>
...
<img src="/plugin/PluginForJenkins/images/claim.png" onClick="javascript:lockMismatch(${instanceSecond.hashCode})"/>

Now I'm getting error (visible through GoogleChrome):

1. POST http://localhost:8080/$stapler/bound/c1678e1a-fc77-44d9-b212-2d73bc6e7b80/lockMismatch 413 (FULL head) prototype.js:1585

4. klassprototype.js:101
5. proxy.(anonymous function)bind.js:51
6. lockMismatch(index):107
7. onclick

There seems to be 2 reasons:
-somehow I'm passing too much data (how?!)

- more possible: I'm doing something wrong ;-(

Could you aid me, please?
