jquery - Using the data-* on input element -


so have discovered data-* attribute , have been using ajax set the id's on link element destination.

ex;

<a id="link_id" href="url_for_no_ajax" class="some_class" data-container="#main">display text</a>

so way can create php function make link non-java users , use id attribute , data-container attribute ajax.

it working fine.

i wanted same inputs element reason not working. data-* attribute not showing in source of page.

so must assume cant use data-* attribute input's

so question element can take data-* attribute? or if faster answer witch can't take it?

tank stackoverflow community! (=

edit

the line output input php :

echo '<input id="'.$id.'" type="'.$type.'" name="'.$name.'" size="'.$size.'" class="'.$class.'" value="'.$value.'"><br><br>';

then how retrieve value of data attribute jquery ajax :

var data_type = ($(this).attr("data-type"));

if alert(data_type) telling me undefined.

inputs can take data element. here test case:

jsfiddle demo

html:

<a href="#" data-container="a-tag">click me</a><br><br> <input type="text" data-container="an_input" /><br><br> <div data-container="a_div">div here</div>

js:

$('*').click(function(){     var d = $(this).data();   alert(d.container);   return false; });

http://api.jquery.com/data/

the .data() method allows attach data of type to dom elements in way safe circular references , therefore memory leaks.

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; } ...
