jQuery if checkbox is not checked issue

使用 jQuery 检查复选框已选中的属性
I am having an issue picking up when a checkbox is not checked.
我在未选中复选框时遇到问题。
Here is my sample code:
这是我的示例代码：
$(".get-the-look ul input").click(function(){
if("this:checked") {
var product = $(this).attr('alt');
$("#bob div").remove('.'+product);
} else {
alert('asdasd');
}
});
But the alert (if the checkbox isn't checked) never fires... The 'else' never kicks in no matter what state the checkbox is in?
但是警报（如果未选中复选框）永远不会触发......无论复选框处于什么状态，“其他”永远不会启动？
I don't see where I am going wrong.
我不明白我哪里出错了。

you can't pass this:checkedas a string - it won't work as it will be interpreted as a string and always evaluate to true
你不能this:checked作为一个字符串传递- 它不会工作，因为它会被解释为一个字符串并且总是评估为true
use $(this).is(':checked')instead
使用$(this).is(':checked')替代

The string "this:checked"will always evaluate to TRUE. Try this.checkedinstead, i.e., evaluate the property checkedon this:
该字符串"this:checked"将始终评估为TRUE。尝试this.checked代替，即评估财产checked上this：
if(this.checked) { ...
