I have a table TD which is created dynamically. All the TDs created have a CLASS. I have set the first-child Display to NONE. I just need to remove or rename this class just on the first child. Does anyone have any ideas on how I could do this please?
Thanks
$('table td:first').removeClass('className')
要么
$('table td:first').toggleClass('className')
$(".tdClass").get(0).className = "newClassName"
Should do what you want. or
$($(".tdClass").get(0)).removeClass("tdClass");
From the jQuery documentation - http://api.jquery.com/first-child-selector/
$(".myTable TD:first-child").removeClass("old-class-name").addClass("new-class-name");
or
$(".myTable TD:first-child").attr("class", "old-class-name");
$(#tableid td:first-child').removeClass('oldClass').addClass('newClass');
will work, provided that you substitute to correct id for #tableid
