如果父 div 具有某些特定类，如何忽略子 DIV

Question

How can I ignore the class extra for child div with class child2 ?

<div class="parent extra">
    <div class="child1">
        Some text
    </div>
    <div class="child2">
        Some text
    </div>
</div>

The extra class is used for translating the texts inside divs ,but I don't want to translate the child div with class child2 . How can I filter this?

Answer 1

The 'extra' class is used for translating the texts inside divs,but I don't want to translate the child div with class 'child2'.How can I filter this?

$('.extra :not(.child2)')

This selector is saying

1. Grab all elements with class extra
2. Search all direct/nested children(the meaning of the space)
3. Grab all direct/nested children which do not have a class of child2

Answer 2

You can :

1. loop all div with parent class --> $( ".parent" ).each()

2. check if the current class has a class extra --> if($(this).hasClass( "extra" ){}

3. if the current parent class has a class extra loop all children and check if it has a child with class : child2 $(this).children().each() and if($(this).hasClass( "child2" )){}

4. If it is the case get the parent and do some process...
