javascript - 如何将事件与生成的动态数据绑定(bind)

Question

我无法将 jQuery 事件与动态生成的 html 数据绑定(bind)。这是我的代码。请帮助我度过难关。 我已经尝试过 on() 函数，但它仍然不起作用。多个指南指导使用 on() 方法解决此问题，但它不起作用。请引导我完成这个过程。谢谢

Answer 1

而不是...

$('.minimize').click(function(e){
//..
});

你可以写...

$('body').on('click', 'a.minimize', function() {
           var h = $(this).parents(".header");
           var c = h.next('.body-content');
           var p = h.parent();
           console.log(this);
           c.slideToggle();

           p.toggleClass('closed');

           //e.preventDefault();
       });

我尝试了一下，它有效，因为有一个 related question
