我有$(document).ready(function() {
$('.photoBackground').on('click',function () {
var idIClickedOn = '#' + $(this).attr('id'); //this will give you the actual id of the element
var image = $(idIClickedOn ).css('background-image');
// remove "url(" and ")" to get the url
image = image.replace('url(','').replace(')','');
$("#lightbox").css('background-image','url(' + image + ')');
var captionOG = $(this).find('p.photoCaption'); $(".photoCaptionBig").text($(captionOG).text().replace(captionOG, "photoCaptionBig"));
$('#lightbox_shadow_container').show();
$('#lightbox-shadow').show();
$('#lightbox').show();
});
$('#lightbox-shadow').click(function() {
$('#lightbox').hide();
$('#lightbox-shadow').hide();
$('#lightbox_shadow_container').hide();
$('#lightbox').css("background-color", "");
});
$(".lightboxCancelCross").click(function(){
$("#lightbox-shadow").trigger("click");
});
});我希望使用向量分解为data.frame的列表，该向量将告诉我每个连续列表元素中应该有多少行。
样本数据
data.frame期望的结果
vectornom <- c(1,2,4,3)
df <- data.frame(x=1:10,y=11:20)
感谢您的帮助
