jQuery绑定和取消绑定委托 [英] jQuery binding and unbinding delegate

问题描述

如何在jquery中绑定和取消绑定.delegate. 假设我使用此js即可轻松点击.

How can i bind and unbind a .delegate in jquery. Say i use this js for simple clicking.

function spanclick(){
    $(this).html('<input class="mm" value="' + $(this).text() + '"/>');
    $(this).unbind("click");
}
$("span.la").click(spanclick);
$("span.la").unbind("click");

但是现在我想切换到委托来代替简单的单击.
因为我当然想将其用于在页面加载时尚未创建的选择器.还是我需要使用.live()
问题: 我如何在jquery中bind和unbind delegate's?

But now i want to switch to delegate in place of simple click.
Because as of course i want to use it to selectors that have not been created on the time of page load. or do i need to use .live()
Question: How do i bind and unbind delegate's in jquery ?

推荐答案

要使用委托，请使用span.la父元素(首选)或document或body:

To use delegate, use span.la parent element (preferred) or document or body:

$(document).delegate('span.la', 'click', spanclick);

取消删除:

$(document).undelegate('span.la', 'click');
