How to use firebug console.log to find jquery parent/children in a <ul>
I'm just trying to print back to better understand how to move around the tree traversal using console.log.
When I click on a parent I'd like to print back it's children. I thought it would be easy as
console.log($(event.target).children());
I've tried to use
console.log($(event.target).children("ul li a"));
It gives me []. I'm looking to print out the child's ID.
HTM:
<body>
<div class = "testButton">
<ul>
<li>
<a href="#" id = "Button One"> Parent One </a>
<ul>
<li> <a href="#" id = "P1 child">P1 child</a> </li>
</ul>
<a href="#" id = "Button Two"> Parent Two </a>
<ul>
<li> <a href="#" id = "P2 child">P2 child</a> </li>
</ul>
<a href="#" id = "Button Three"> Parent Three </a>
<ul>
<li> <a href="#" id = "P3 child">P3 child</a> </li>
</ul>
<a href="#" id = "Button Four"> Parent Four </a>
<ul>
<li> <a href="#" id = "P4 child">P4 child</a> </li>
</ul>
</li>
</ul>
</div>
</body>
</html>
CSS:
.testButton ul {
list-style-type: none;
padding-left: 0;
margin-left: 0;
}
.testButton li {
display: inline;
}
.testButton a {
display: block;
width: 6em;
text-align: center;

}
.upButton {
background-color: #ccc;
color: #000;
}
.overButton {
background-color: #222;
color: #fff;
}
.outButton {
background-color: #ccc;
color: #000;
}
.clickButton {
background-color: #F90;
color: #222;
}
JS:
google.load('jquery', '1.6.2');
google.setOnLoadCallback(function(){
$(".testButton a").addClass("upButton");
$(".testButton a").mouseover(function(event){
$(event.target).removeClass("outButton").addClass("overButton");
});
$(".testButton a").mouseout(function(event){
$(event.target).addClass("outButton");
});
$(".testButton a").click(function(event){
$(".testButton a").removeClass("clickButton");
$(event.target).addClass("clickButton");
$(this).blur();
console.log($(event.target));
console.log($(event.target).children());
console.log($(event.target).parent().children());
console.log($(event.target).siblings());
});
});
This should do the trick for the structure of your ul/li/a tags.
DEMO
For the demo I have just simply alerted the ids for you. You can change these to console.log if you like. So now what I did...
$('.button').click(function() {
$(this).next('ul').children().each(function() {
alert($(this).children('a').attr('id'));
});
});
I added a class 'button' to each of your parents just to make it clear. So now when any item with a class 'button' is clicked, we get the next 'ul' in your html structure - (next() gets the next element at the same hierachy level of your code). Then for each child within that 'ul' I have alerted the id of each anchor within each child (as your structure is <li><a id="..."></li>).
