我试图利用咖啡厅/咖啡厅做以下工作:
(1) 重提在html上展示的所有专题(见下文)。
(2) 除所列前5个专题外,所有专题均采用显示方式。
I tried to do the following but is not working
//Retrieve the entire list of and hide all but the first 5 topics in the list
$(".topics .topic")[5..-1].hide()
Can someone advise me on how I can correctly retrieve the list of topics from the HTML document and subsequently hide ALL but the first 5 topics?
$(".topics .topic").slice(5).hide();
http://api.jquery.com/slice/"rel=“noretinger”> http://api.jquery.com/slice/。
Check out the jQuery gt() selector:
$(".topics .topic:gt(4)").hide();
页: 1
$(".topics .topic")[5..-1].hide()
应当开展工作,因为它汇编到$(......topics .topic”).slice(5).hide(和)确实是你想要的。 因此,我猜测,在OMM处于正确状态之前,你的法典正在运行。 您
$(document).ready -> $(".topics .topic")[5..-1].hide()
? 当你做什么时,你会做些什么?
alert $(".topics .topic").length
页: 1
如果问题与选择无关,则问题必须放在<代码>hide(<>hide(>>上,后者通过修改中央支助事务网上的目标开展工作。 你也许会凌驾于《社会保障法》其他条款。 利用“快速要素”获取细节。
