在append()上做某事 [英] on append() do something

问题描述

当元素附加到DOM时是否可以添加某种事件/处理程序??

Is it possible to add some kind of an event/handler when an element is appended to the DOM...?

.click()、. change()、. keyup()等...

.click(), .change(), .keyup() etc. alike...

我需要在附加元素后立即获取其高度，然后将其设置为另一个元素

I need to get the height of an element as soon as it is appended and then set the height to another element

推荐答案

您可以覆盖默认的append方法，并使其触发自定义的追加事件.然后将处理程序绑定到该事件的元素: http://jsfiddle.net/H8ygx/

You can override the default append method and cause it to trigger a custom append event. Then bind a handler to an element for that event: http://jsfiddle.net/H8ygx/

(function($) {
    var origAppend = $.fn.append;

    $.fn.append = function () {
        return origAppend.apply(this, arguments).trigger("append");
    };
})(jQuery);

$("div").bind("append", function() { alert('Hello, world!'); });

$("div").append("<span>");
