I was wondering how I could use JQuery to select the child of a parent?
I have the following.
$("#navigation a.subpage").click(function () {
$("#navigation ul ul")...
The HTML looks like this.
<li>
<a class="subpage"...</a>
<ul style="hidden">...</ul>
</li>
I need to somehow select the parents of the link. That would get me the relevant li. Then I need to select the ul and toggle it. How do I do this?
Keep it simple:
$("a.subpage").click(function() {
$(this).next().toggle();
return false;
});
this
in an event handler is the source of the event, being the link.
Edit: the issue of whether or not next()
is appropriate. Of course if the markup is different you use a different chain. There are many ways of achieving the same result, for example:
$(this).siblings("ul").toggle();
But what if the link is inside a paragraph?
$(this).closest("li").children("ul").toggle();
But what if the list isn't a direct child?
Etc etc etc. All of these are reasonable approaches but keep it simple: Write your jQuery code to suit your markup rather than trying to cater for things that don't happen and probably never will.
