# jquery.js:5092 \[Violation] Added non-passive event listener to a scroll-blocking 'touchstart' (ok)

This solve the problem to me:

```
jQuery.event.special.touchstart = {
  setup: function( _, ns, handle ){
    if ( ns.includes("noPreventDefault") ) {
      this.addEventListener("touchstart", handle, { passive: false });
    } else {
      this.addEventListener("touchstart", handle, { passive: true });
    }
  }
};
```

I am using various events and this seems to solve my use case

```
(function () {
    if (typeof EventTarget !== "undefined") {
        let func = EventTarget.prototype.addEventListener;
        EventTarget.prototype.addEventListener = function (type, fn, capture) {
            this.func = func;
            if(typeof capture !== "boolean"){
                capture = capture || {};
                capture.passive = false;
            }
            this.func(type, fn, capture);
        };
    };
}());
```
