jQuery .ready在动态插入的iframe中 [英] jQuery .ready in a dynamically inserted iframe

问题描述

我们正在使用jQuery thickbox 在有人点击图片时动态显示iframe。在这个iframe中，我们使用 galleria javascript库来显示多张图片。

We are using jQuery thickbox to dynamically display an iframe when someone clicks on a picture. In this iframe, we are using galleria a javascript library to display multiple pictures.

问题似乎是，iframe中的 $（document）.ready 似乎过早被触发并且iframe内容甚至还没有加载，所以在DOM元素上没有正确应用galleria代码。 $（document）.ready 似乎使用iframe父级就绪状态来判断iframe是否准备就绪。

The problem seems to be that $(document).ready in the iframe seems to be fired too soon and the iframe content isn't even loaded yet, so galleria code is not applied properly on the DOM elements. $(document).ready seems to use the iframe parent ready state to decide if the iframe is ready.

如果我们在单独的函数中提取由文档就绪调用的函数，并在超过100毫秒后调用它。它有效，但我们不能利用慢速计算机来生产。

If we extract the function called by document ready in a separate function and call it after a timeout of 100 ms. It works, but we can't take the chance in production with a slow computer.

$(document).ready(function() { setTimeout(ApplyGalleria, 100); });

我的问题：我们应该绑定哪个jQuery事件，以便能够在动态iframe时执行我们的代码准备好了，而不仅仅是它的父母？

My question: which jQuery event should we bind to to be able to execute our code when the dynamic iframe is ready and not just it's a parent?

推荐答案

我回答了类似的问题（参见 IFRAME加载完成后的JavaScript回调？）。
您可以使用以下代码获取对iframe加载事件的控制权：

I answered a similar question (see Javascript callback when IFRAME is finished loading?). You can obtain control over the iframe load event with the following code:

function callIframe(url, callback) {
    $(document.body).append('<IFRAME id="myId" ...>');
    $('iframe#myId').attr('src', url);

    $('iframe#myId').load(function() {
        callback(this);
    });
}

在处理iframe时，我发现使用load事件而不是文档就绪事件。

In dealing with iframes I found good enough to use load event instead of document ready event.
