i new jquery, , i'm having trouble doing thought should simple find , replace operation.

i want remove disabled attribute. searching jquery remove sample, using id or tag.

$("body *").replacetext( /disabled|disable/gi, "enable" ); 

use selector on attribute , remove when found. way never idea try use regex/replace on html tags

$("a[disabled]").each(function() {   $(this).removeattr("disabled"); });
