javascript - jscript to run at window.onload AND item.onchange -


i'm using jscript load string in several elements of array, display useful element in html.

there's pulldown menu causes string change. so, need function re-run when happens.

i have been able display element using window.onload

and, have been able display element after pulldown menu has been changed.

but, can't seem display element window.onload , subsequently after item.onchage

if has suggestions, i'd grateful.

here code works window.onload

window.onload = function() {     var selectedoptionid = jquery('select').val();     var optionpartnumber = jquery('input[name="optid_' + selectedoptionid + '"]').val();      //loads string in array , returns 2nd element     var optionpartnumber = optionpartnumber.split(".")[1];     document.getelementbyid("masnum").innerhtml=optionpartnumber; }

here code works pulldown.onchange

jquery(function(){   jquery('.dropdownimage-format select').on('change', function(){    var selectedoptionid = jquery('select').val();    var optionpartnumber = jquery('input[name="optid_' + selectedoptionid + '"]').val();      var optionpartnumber = optionpartnumber.split(".")[1];     document.getelementbyid("masnum").innerhtml=optionpartnumber;   });

in both cases, element displayed in html by

    <a id="masnum">

css - Make div keyboard-scrollable in jQuery Mobile? -

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; } &l
