问题
I'm sure someone in the know has a solution to this problem I'm facing? I have a site with Index.html which contains an Iframe. In this iframe, all pages of the site are shown...Home.html..Info.html...Contact.html..etc.
I'd like a javascript function so that when you open Home.html via the google sitemap for example, it shows up in the parent frame in Index.html. The function I currently have in the head section of each child page is:
<script>
if (parent.location.href == self.location.href){
window.location.href = 'index.html'
}
</script>
Although this works, it doesn't remember the child page and opens the Index page with the default iframe page...Home.html as the iframe is coded like this:
<iframe id="iframe" src="home.html" allowTransparency="true" id="iframeID" name="iframeID" width="100" height="100" scrolling="no" frameborder="no">
</iframe>
Has anybody a solution to this problem, as I've searched everywhere? Thanks.
回答1:
Try to set location.href with a query string, i.e.:
// .getAttribute so we don't get the absolute URL
var src = document.getElementById("iframe").getAttribute("src");
if (parent.location.href === self.location.href)
location.href = "index.html?" + escape(src);
In index.html create a check for query strings and set the iframe source accordingly:
if (location.search)
document.getElementById("iframe").src =
unescape(location.search.substring(1));
