Original post: Why doesn't this simple script work?
if ($('#navigation > ul > li > ul > li > a').hasClass('.active')) {
$(this).parent().parent().parent().addClass(".active");
}
EDIT:
This won't hide the H1:
if ($('#content h1').hasClass('aktiv')) {
$(this).hide();
}
Only this will:
if ($('#content h1').hasClass('aktiv')) {
$('#content h1').hide();
}
Why can't I use the (this)?
This question is related to
javascript
jquery
addclass
Alternatively you could use:
if ($('#navigation a').is(".active")) {
$(this).parent().addClass("active");
}
You can't use $(this)
since jQuery doesn't know what it is there. You seem to be overcomplicating things. You can do $('#content h1.aktiv').hide()
. There's no reason to test to see if the class exists.
If anyone is using WordPress, you can use something like:
if (jQuery('.dropdown-menu li').hasClass('active')) {
jQuery('.current-menu-parent').addClass('current-menu-item');
}
The reason that does not work is because this
has no specific meaning inside of an if statement, you will have to go back to a level of scope where this
is defined (a function).
For example:
$('#element1').click(function() {
console.log($(this).attr('id')); // logs "element1"
if ($('#element2').hasClass('class')) {
console.log($(this).attr('id')); // still logs "element1"
}
});
You probably want to change the condition to if ($(this).hasClass('active'))
Also, hasClass
and addClass
take classnames, not selectors.
Therefore, you shouldn't include a .
