请参阅Accessing Parameters *and* Events in function from jQuery Event
如何更改此代码，使$(this)在单击事件中的行为类似于$(this)，而不是返回完整的html文档？

像这样重构它：
function functionToCall(ev) { // ev -> event is passed by jQuery by default
var clickedItem = this; // this refers to the element that is clicked
// both accessible here
alert(ev.type);
//console.debug(clickedItem); // this may not work in all browsers. see my fiddle for a failsafe.
// failsafe: check if console exists
if(window.console && window.console.debug) { console.debug(clickedItem); }
alert($(clickedItem).attr('id')); // $() to get jQuery object
}
$(document).ready(function() {
$("a").live("click", functionToCall); // just need to pass a function reference
}); 演示：http://jsfiddle.net/mrchief/ZYGVz/1/

尝试如下所示：
$("a").each(function(){
$(this).live("click",functionToCall($(this)));
