jQuery脚本只能运行一次 [英] jQuery script works only once

问题描述

我没什么问题，脚本只能运行一次，之后我需要刷新页面以删除喜欢的文章(脚本就是针对此).

I have little problem, script works only once, after that I need to refresh page to remove favorite article (script is for that).

$("a.fav_no").on('click', function () {
            var id = $(this).attr("id");
            $(this).load("{$homepage}/user_action.php?action=fav&id="+ id +"").addClass("fav_yes");
        });

$("a.fav_yes").on('click', function () {
            var id = $(this).attr("id");
            $(this).load("{$homepage}/user_action.php?action=remove_fav&id="+ id +"").removeClass("fav_yes");
        });

在控制台中，单击多次(因此计算在内)后，单击后得到的文章ID为(div)，但它无济于事.因此，我现在可以只选择收藏夹，要从收藏夹中删除，我需要刷新，然后再次单击链接以从收藏夹中删除.

In console, I get id of article (div) on click after many times on click (so it count) but it doesn't do anything. So I can right now just favorite, to remove from favorites I need to refresh then to click again on link to remove from favorites.

谢谢！

推荐答案

如果您使用.on()重载，该重载需要3个args，并且在文档上被调用.然后，事件将随着UI元素的来来去去而保持连接.无需每次都重新添加它们.

If you use the .on() overload that takes 3 args and is called on the document. Then the events will remain hooked up as UI elements come and go. No need to re add them every time.

$(document).on("click"，"a.offsite"，function(){.....

$(document).on("click", "a.offsite", function(){ .....
