Jquery: bind load + change simultaneously
提问by max
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:
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（如“更改”）。我认为最好的方法是将其放在同一行中：
$('#element_id').bind('load, change', function () {
...
});
But this works only for "change" and not for "load". There is a better way?
但这仅适用于“更改”而不适用于“加载”。有一个更好的方法？

I stumbled across the same problem. Removing comma is not enough, at least not in this case:
我偶然发现了同样的问题。删除逗号是不够的，至少在这种情况下不是：
$(document).ready(function(){
$('#element_id').bind('load change', function () {
... // (this DOESN'T get called on page load)
});
});
I guess loadevents get triggered before $(document).ready().
我猜load事件在$(document).ready().
This is a simple solution:
这是一个简单的解决方案：
$(document).ready(function(){
$('#element_id').bind('change', function () {
...
});
$('#element_id').trigger('change');
});

For already loaded content, when you want to run a function on an event and also straight away, you can use a custom event of your own naming to avoid triggering any existing bindings from libraries etc. on the built in events, e.g.
对于已经加载的内容，当你想在一个事件上运行一个函数并立即运行时，你可以使用你自己命名的自定义事件来避免在内置事件上触发来自库等的任何现有绑定，例如
$(".my-selector").on("change rightnow", function() {
// do stuff...
}).triggerHandler("rightnow");

Don't you just need to remove the comma?
你不是只需要删除逗号吗？
回答by DMac the Destroyer
try it without the comma:
尝试不带逗号：
$('#element_id').bind('load change', function () {
...
});
