jQuery Cant删除li一旦添加 [英] jQuery Cant remove li once added

问题描述

当我在列表中添加新的<li>，然后尝试将其删除时，它不会让我从列表中删除新添加的功能吗?

When I add in a new <li> into the list, and then I try to remove it, it won't let me remove newly added features from the list?

推荐答案

由于浏览器在读取您的JavaScript代码时，动态添加的li不在DOM中，因此无法找到它.而是将处理程序添加到父级，然后像这样监听a:

Cause when the browser is reading your javascript code the dynamically added li isn't in the DOM, so it can't find it. Instead add the handler to the parent, and listen for the a like this:

$('#cblist').on('click', 'a', function(){
    $(this).parent('li').remove();
    return false;
});
