Jquery 选择器中使用变量的例子

$("#" + this.id).hide();

OR you can do something like this.

var id = this.id;

$('#' + id).hide();

OR you can give some effect also.

$("#" + this.id).slideUp();

If you want to remove the entire element permanently form the page.

$("#" + this.id).remove();

You can also use it in this also.

$("#" + this.id).slideUp('slow', function (){
$("#" + this.id).remove();
});
