javascript - Do I need e.stopPropagation() and e.preventDefault()? -


in javascript/jquery, registering click , touchstart events on button, this:

$('#open-about-popup').on('touchstart click', openaboutpopup_eventhandler)

then in event-handler, have this:

e.stoppropagation();  e.preventdefault();

this causing next button-click not fire. have wrong?

thanks.

e.stoppropagation() prevents event bubbling dom tree, e.preventdefault() prevents browser doing whatever default behavior associated event - e.g. click event on <a> tag make browser redirect href of link, if use preventdefault, won't that.

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
