The active pseudo class of the mobile button is invalid

long pressing the press event will cause the browser to pop up the menu. Apple"s can use: please enter the code-webkit-touch-callout: none; to disable it, but Android can"t. The prohibition of pop-up can only be controlled with j and bold text s:
window.ontouchstart = function (e) {

e.preventDefault(); 

};
in this way: active is invalid. Is there any way to guarantee the button: active, can also prohibit Android browsers from pressing the pop-up menu?
