How to add color change functionality to Sir Trevor JS?

Question

Angular

There is a site on yii1 + sir trevor js 3.0
I just can't add the functionality to change the color. The button appeared, I don’t know what to do next. Settled on this:

var Color = SirTrevor.Formatter.extend({
      title: "color",
      cmd: "color",
      text : "C",
      onClick: function() {
          var color = prompt(i18n.t("general:color"));

          document.execCommand(this.cmd, false, color);
      }
});
 SirTrevor.Formatters.Color = new Color();

And why don't you immediately filter the entire collection in the place where you fill in filteredMonitorings?

this.monitoringsService.getFilteredMonitorings().subscribe(rows =>
      this.filteredMonitorings = rows
        .filter(monitoring => monitoring.spr_prioritys_id)
        .filter(monitoring => monitoring.n_users_id)
        .filter(monitoring => monitoring.priority_itog));

I asked this question based on your line
Because you are checking here that monitoring.spr_prioritys_id is not null, and that monitoring.n_users_id and monitoring.priority_itog are also not null or 0
