A similar questionwas recently posted specific to iFrames with Twitter Bootstrap-based tabs, which I answeredusing a technique I'm calling Lazy Loading of iFrames. The js/jquery is as follows; see the full code including html markup in the fiddle or on my response to the OP:
最近发布了一个类似的问题，专门针对带有基于 Twitter Bootstrap 的选项卡的 iFrames，我使用一种我称之为Lazy Loading of iFrames的技术回答了这个问题。js/jquery 如下；查看完整代码，包括小提琴中的 html 标记或我对 OP 的回应：
<script>
$('#myTabs').bind('show', function(e) {
// identify the tab-pane
paneID = $(e.target).attr('href');
// get the value of the custom data attribute to use as the iframe source
src = $(paneID).attr('data-src');
//if the iframe on the selected tab-pane hasn't been loaded yet...
if($(paneID+" iframe").attr("src")=="")
{
// update the iframe src attribute using the custom data-attribute value
$(paneID+" iframe").attr("src",src);
}
});
</script>

Here is a WordPress plugin you can download and manually install via the WordPress plugin repository. I created this today just to handle this situation. No changes to content are needed, this works automatically once activated on any and all iframes.
这是一个 WordPress 插件，您可以通过 WordPress 插件存储库下载并手动安装。我今天创建这个只是为了处理这种情况。不需要更改内容，一旦在任何和所有 iframe 上激活，它就会自动工作。

You could always intialize the src attribute to about:blank and then when your click event fires, set the src attribute to the URL you want to navigate to.
您始终可以将 src 属性初始化为 about:blank，然后当您的点击事件触发时，将 src 属性设置为您要导航到的 URL。
