从 iFrame 卸载/删除内容 [英] Unloading/Removing content from an iFrame
问题描述
无论如何要卸载已加载到 iframe 中的页面?如果可能，我不想将 iframe src 更改为空白页面.我基本上是在寻找可以做这样的事情的东西 $('#frameID').attr("src",""); 除了代码似乎没有清除以前加载的页面.
Is there anyway to unload a page that has been loaded inside an iframe? I do not want to change the iframe src to a blank page if possible. I am basically looking for something that will do something like this $('#frameID').attr("src",""); except that code does not seem to clear the previously loaded page.
是否有我可以调用的 "unload" 函数，该函数将重置 iframe，使其内部没有加载任何内容?
Is there a "unload" function that I can call which will reset the iframe so that it does not have any content loaded inside?
推荐答案
其他解决方案使用 innerHTML，这在 XHTML 中并不总是有效.他们也只清除 document.body( 中的任何内容仍然存在).这是一个使用 DOM 的解决方案:
The other solutions use innerHTML, which won't always work in XHTML. They also only clear document.body (anything in the <head> is still present). Here is a solution that uses the DOM:
var frame = document.getElementById("myFrame"),
frameDoc = frame.contentDocument || frame.contentWindow.document;
frameDoc.removeChild(frameDoc.documentElement);
此解决方案使用 innerHTML:
var frame = document.getElementById("myFrame"),
frameDoc = frame.contentDocument || frame.contentWindow.document;
frameDoc.documentElement.innerHTML = "";
