委托jquery - 获取父容器

Question

我想选择p.section容器中的所有元素,但只是在包含已单击的a.open链接的元素中

$('.section').delegate('a.open', "click", function(){
    $(this).parent().filter('p').show(); //I want to select all `p` elements in .section container, but just in th one that containts the a.open link that has been clicked
})

谢谢

您可以将delegateTarget作为上下文传递(delegateTarget是事件对象的一个​​属性,它传递给处理函数,并且是"处理"委托的DOM元素

$('.section').delegate('a.open', "click", function(e){
    $('p', e.delegateTarget).show()
    //This means show all <p> elements in the context defined by e.delegateTarget
})
