Check if iFrame is loaded. ONE time. Jquery
提问by Oliver 'Oli' Jensen
I know there is many of possiblites when it comes to check if an iFrame content has been loaded. Although, is there anyway to limit it?
我知道在检查 iFrame 内容是否已加载时有很多可能性。虽然,无论如何要限制它吗?
Example, if I have an iframe, and I need to check if everything has loaded, I can use the load() function. Although, if I click a NEW link inside the iframe, it will run the load() function again.
例如,如果我有一个 iframe,并且需要检查所有内容是否已加载,则可以使用 load() 函数。但是,如果我单击 iframe 内的新链接,它将再次运行 load() 函数。
What I wish to know, is there any way to do, so jquery only checks the FIRST time the iFrame content has been loaded?
我想知道的是,有什么办法可以做,所以 jquery 只检查 iFrame 内容已加载的第一次?
I have tried everything, nothing works.
我已经尝试了一切,没有任何效果。

You can unset the load callback again once it gets called.
一旦它被调用,您可以再次取消设置加载回调。
$('#iframe').load(function() {
// do things which are awesome
$('#iframe').unbind('load');
});
