Good Morning,
Sorry i think its a simple "stupid" question but i have a big blank.
I want to change a class if the attr value is equal to a given value.
I have the following:
<a str=10 href="start.php class="old">Start<a>
So if str attr from a is 10 i will set the class to class="new"
I have tried somethig like:
$('a.attr.subnr.10).addClass('old');
I think its to early in the morning :-(
Thank you !
Try this simple statement:
$("a[str='10']").addClass("old");
First of all, str is not a valid attribute, consider using data-str
You can do it like
if($('a').attr('data-str') == 10) {
$('a').addClass('add_class');
}
Make sure you use a specific selector, this is a generalized one, so consider using something like .parent a
If you want a pure CSS solution, than you can also use attr=value selector like
a[data-str="10"] {
color: red;
}
This won't add a class to your element, but you can target it using the above selector.
$('a[str=10]').removeClass('old').addClass('new');
try this
$('a[str=10]').removeClass('oldClass').addClass('newClass');
$('a[str!=10]').removeClass('newClass').addClass('OldClass');
