html - how to replace data("id") in jquery -

i had nestable want alter

data-id="12"

to

may max data-id equals 17

and want alter data-id value

data-id="39"

here code: class="snippet-code-html lang-html prettyprint-override"><!--before--> <div class="dd" id="nestable"> <ol class="dd-list" id="depth1_ol"> <li data-id="12"><div class="dd-item">item 12</div></li> </ol> </div> <!--after--> <div class="dd" id="nestable"> <ol class="dd-list" id="depth1_ol"> <li data-id="39"><div class="dd-item">item 39....</div></li> </ol> </div>

how can this??

your question bit unclear i'm assuming need alter data-id attribute. well, alter value using jquery can using data method below...

$("li").data("id", "39");

however, aware not alter actual dom element, stored in memory farther manipulation within jquery framework. if you want alter dom directly, utilize attr method below...

$("li").attr("data-id", "39");

jquery html
