jQuery:绑定负载+同时更改 [英] Jquery: bind load + change simultaneously

问题描述

在许多情况下，我需要在加载后将行为绑定到元素，然后在事件触发后将其绑定到元素(例如"change"). 我认为最好的方法是使它处于同一行:

In many cases, I need to bind a behaviour to an element after loading, and then after an event triggering (like "change"). I think the best way would be to make it in the same line:

$('#element_id').bind('load, change', function () {
...
});

但这仅适用于更改"，不适用于负载".有更好的方法吗?

But this works only for "change" and not for "load". There is a better way?

推荐答案

我偶然发现了同一问题.删除逗号是不够的，至少在这种情况下还不够:

I stumbled across the same problem. Removing comma is not enough, at least not in this case:

$(document).ready(function(){
    $('#element_id').bind('load change', function () {
        ... // (this DOESN'T get called on page load)
    });
});

我想load事件是在$(document).ready()之前触发的.

I guess load events get triggered before $(document).ready().

这是一个简单的解决方案:

This is a simple solution:

$(document).ready(function(){
    $('#element_id').bind('change', function () {
        ...
    });
    $('#element_id').trigger('change');
});
