修改iframe.src而不输入历史记录对象 [英] Modify iframe.src without entry to history object
问题描述
我的网页上有一个iframe。我通过javascript修改src属性,如下所示:
I have an iframe in my web page. I modify the src property via javascript like so:
document.getElementById('myiframe').src = 'http://vimeo.com/videoid1';
document.getElementById('myiframe').src = 'http://vimeo.com/videoid2';
document.getElementById('myiframe').src = 'http://vimeo.com/videoid3';
然而,每次我这样做,它都会记录在浏览器的历史记录中。因此,每次我在浏览器窗口中按下时,iframe内容都会从videoid3转到videoid2到videoid1。如果我再次按回,整个页面都会返回。
However, everytime I do this, it's logged into the browser's history. So everytime I press back in the browser window, the iframe content goes from videoid3 to videoid2 to videoid1. If I press back again, the entire page goes back.
我想用javascript修改iframe src而不在浏览器的历史记录中记录条目。因此,如果我单击浏览器后退按钮,整个页面将返回而不更新iframe。
I would like to modify the iframe src with javascript WITHOUT logging an entry into the browser's history. So if i click the browser back button, the entire page goes back without updating the iframe.
我尝试过这样的事情:
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid1');
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid2');
document.getElementById('myiframe').contentWindow.location.replace('http://vimeo.com/videoid3');
虽然这使得浏览器后退按钮按照我想要的方式运行,但它破坏了vimeo中的某些内容视频。 Vimeo要求您通过iframe.src而不是contentWindow.location.replace()来更改URL。
Although this made the browser back button behave the way I wanted to, it broke certain things in the vimeo video. Vimeo REQUIRES you to change urls via the iframe.src instead of contentWindow.location.replace().
因此,如何在不登录的情况下修改iframe.src历史?
As such, how do I modify the iframe.src WITHOUT logging into history?

推荐答案
不要更改src,只需用新的iframe替换旧的iframe?
don't change the src, just replace the old iframe with a new one?
<!doctype html>
<style>
iframe {
width: 300px;
height:300px;
}
</style>
<script>
var urls = ["http://bing.com", "http://google.com", "http://duckduckgo.com"];
function next() {
if(urls.length==0) return;
var original = document.getElementsByTagName("iframe")[0];
var newFrame = document.createElement("iframe");
newFrame.src = urls.pop();
var parent = original.parentNode;
parent.replaceChild(newFrame, original);
}
</script>
<p>let's test some iframes</p>
<button onclick="next()">next</button>
<iframe />
没有历史记录。功能相同。每个人都赢了。
No history states. Same functionality. Everyone wins.
