如何在JQuery中的另一个对象中获取对象

Question

如何获得我在bootbox.confirm()内点击的li？

<ul id="something">
  <li>Result 1</li>
  <li>Result 2</li>
  <li>Result 3</li>
</ul>

$('#something li').click(function(){
    bootbox.confirm("Are you sure?", function(result) {
    if(result == true){
        alert("You deleted" + /*here I want to get the item that was clicked*/);
        }
    }); 
});

Answer 1

使用this缓存上下文：

$('#something li').click(function(){
    var $this = this; // cache it here
    bootbox.confirm("Are you sure?", function(result) {
        if(result == true){
           alert("You deleted" + $this.textContent/*use it here now!!*/);
        }
    }); 
});

Answer 2

您可以在此上下文中使用$( this )。

$('#something li').click(function(){
    console.log($( this ));
});
