获得每个可见儿童的班级
原标题:Getting class of each visible child

我正在动态地创建新输入的间隔。 如果标题输入有某些明显的孩子, 我希望新输入的孩子也能看到这些班级 。

我想要的东西,比如:

var visibleClass = $( #titlediv ).children().is( :visible ).each( .class );

$( #newinput ).children( span ).hasClass( .  + visibleClass).show();

这是创建新输入和 div 的函数的代码示例。 在此示例中,. catsaddad 指的是变量中所有包含类 cadad 并有自己独特类的所有图像 :

var item = $( <input /> );

item.attr({ type : text ,  size :  33px  ,  class : inputItem  ,  id : item  + nextItemId })

.appendTo( #itemDiv  + nextItemId);



    //Create Span for category selections

$( <span /> ).attr({ class : dynamiccat  ,  id : categorydiv  + nextItemId})

.prependTo( #itemDiv  + nextItemId);

$( #categorydiv  + nextItemId).append(allimages);

$( .dynamiccat ).hide();

$( .catsadd ).hide();

感谢各位的帮助!

最佳回答

如果我说对了,你想得到 可见元素的所有分类:

var visibleClasses = $( #titlediv :visible[class] ).map(function(){
    return this.className.split(s);
}).get();

直接儿童:

var visibleClasses = $( #titlediv > :visible[class] ).map(function(){
    return this.className.split(s);
}).get();
