Summon wicket from the non-wicket-component entity

I am currently utilizing js-lib to transform text into a rich-editor, complete with options such as "bold", "italic" and more.

The RichEditor also includes an UploadImage button, for which I am able to modify the call-back function:

function startUploadingImage(field_name, url, type, win) {
    //
}

In addition, I have designed a modal window for selecting files. My question is, how can I trigger wicket from the "startUploadingImage" function?

I attempted something like this:


// Java-script:
function startUploadingImage(field_name, url, type, win) {
    wicketAjaxGet('..?1-1.IBehaviorListener.0-&action=uploadImage');
}

// and Wicket (class extends WebPage):

clickBehavior = new AbstractDefaultAjaxBehavior() {
    @Override
    protected void respond(AjaxRequestTarget target) {
        IRequestParameters requestParameters = getRequestCycle().getRequest().getRequestParameters();
        String action = requestParameters.getParameterValue("action").toString();
        if (action.equals("uploadImage"))
            modal1.show(target);
    }
};
add(clickBehavior);

Unfortunately, this method did not work as expected. I am still in the early stages of learning wicket, so I am facing some challenges.

Answer №1

To ensure that the AbstractDefaultAjaxBehavior url is accessible to JavaScript for calling, one method is to include a new data tag in the component's HTML where the AjaxBehavior is added. This can be achieved by customizing the onComponentTag method of the AbstractDefaultAjaxBehavior.

@Override
protected void onComponentTag(ComponentTag tag) 
{       
    tag.put("callback-url", behavior.getCallbackUrl());     
    super.onComponentTag(tag);
}

Subsequently, in the JavaScript code, retrieving the value of the callback-url tag will provide the necessary URL to call.

wicketAjaxGet($element.attr('callback-url'), function() { }, function() { });
