Take a look at jQuery custom selectors. Personally, I would use HTML5 data attributesfor cases such as this which is already supportedin jQuery.
看看 jQuery自定义选择器。就我个人而言，我会在 jQuery已经支持的情况下使用 HTML5数据属性。
For whatever it's worth, considering the parameter I believe what are you trying to originally perform should be done like
无论它的价值如何，考虑到参数，我相信您最初尝试执行的操作应该像
getComments = function(input) {
fValue = $(input).html( $(input).attr("store-id") );
alert('the ID :'+fValue.html());
}

all you have to do is :
你所要做的就是：
fValue = $(input).attr("store-id");
your snippet is trying to add to the 'value' attribute of a div (which does not exist)
您的代码段试图添加到 div 的“值”属性（不存在）
