[英]Why does my jquery reset?
I am attempting to make a second dropdown navigation here, all i want it to do is slide down nicely once its been triggered to show and it does slide down. 我正在尝试在此处进行第二次下拉导航,我想要它做的就是一旦触发显示就很好地向下滑动,并且确实向下滑动。 However it disappears just after a second or so, why does it do that?? 但是,它在一秒钟左右后消失了,为什么要这么做呢?

Jquery jQuery的
$(function() {
$("a").on("click", function() {
$("#lower_nav").slideDown();
});
});
I realised that by clicking a link i am reloading a page, therefore my bar is disappearing. 我意识到通过单击链接可以重新加载页面,因此我的栏消失了。 I solved this with jquery's preventDefault function. 我用jQuery的preventDefault函数解决了这个问题。
