jquery中对于为一组标签赋予点击事件

可以用each，但是each不能对动态的元素进行事件的绑定，

不过，其实也很简单，只需要获取所有的标签集，然后用动态绑定的方法，比如live进行绑定就可以了。

有时候，其实不难，只是自己想的太过复杂。

除此之外，对于已经绑定单击事件的元素，再绑定双击事件，会使得双击事件失效。

可以用以下方法进行解决；

var $timer =null;
    $(".add_val").live('click',function(){     //增加属性值；
        var aaa=$(this);
        var val = aaa.prev();
        clearTimeout($timer);
        $timer =setTimeout(function(){
            val.append("<input type='text' name='attr_val[]' size='5'>");
        },300)

        })

    $(".add_val").live('dblclick',function(){   //删除属性值；
        clearTimeout($timer);
        var aaa = $(this);
        var val = aaa.prev();
        if(val.children().length<2){
            return;
        }else{
            val.children().last().remove();
        }

    })
