Question

Delete comment on specific page using Javascript action

Could anyone please assist me with the following: 

 

Goal:

I would like to adapt the below Javascript action, it should only delete any comment on the same page as the button (where executed) that has a specific author. 

 

My effort so far

this.syncAnnotScan();
var annots = this.getAnnots();

if (annots!=null) {
for (var i=annots.length-1; i>=0; i--) {
           if (annots[i].author == "JonDoe" )
              annots[i].destroy(); 
          }
}

 

Many thanks

Change this line:

var annots = this.getAnnots();

To this:

var annots = this.getAnnots({nPage: event.target.page});

The rest can stay the same.

    Hi,

     

    You should be able to use the page property, so you get the page from the button that was clicked and then you check that against the annot.page property, which tells you which page the annot is on.

    something like

    if ((annots[i].page == button.page) && (annots[i].author == "JonDow")){

     

    Hope this helps

      Completely brilliant, many thanks!

       

      I have a button on several pages, hence:

       

      Page1Button

      var button = this.getField("Purge01");

      [...]

       

      Page5Button

      var button = this.getField("Purge05");

      [...]

       

      Consequently I will need to individually 'hard code' each this.getField when defining the button variable.

      Is there a way of avoiding this?

       

      Best regards

      There is no need to use "getField" to acquire the button object. The button object where the code is being run is provided by the event object, i.e., event.target
