I have the following code for example
$("a.foo").bind(function (e){
var t;
if ( $(e.target).is("a") ){
t = $(e.target);
}else{
t = $(e.target).parent("a");
}
var data = t.attr("data-info");
});
In english. I might have a list of anchors within which there may be a number of spans. Each anchor is declared as
<a class="foo" href="#" data-info="1">
<span> ... </span>
<span> ... </span>
</a>
<a class="foo" href="#" data-info="2">
<span> ... </span>
<span> ... </span>
</a>
...
...
I bind a handler to the click event of the anchor but the event object comes back with the anchor OR one of the spans depending on where I click. So to get my html5 "data-info" value into the callback I have to insert a bit of messy code. This is now appearing throughout my code to the point where I am guessing there might be an idiomatic JQuery way of handling this.
