URL encoding for document.location.href

Question

I am building an iFrame and am using document.location.href -> my exact code is:

<script type="text/javascript">
document.write("<iframe src='http://www.facebook.com/plugins/like.php?href=" + document.location.href + "&layout=standard&show_faces=false&action=like&font=verdana&colorscheme=light' frameborder=0></iframe>");
</script>

This is working great for all of my pages except one. I believe the issue with the one page is caused by a dash "-" being in the page name. My questions is - is there a way to encode my src differently so that the link works? The CORRECT URL I want it to pull is:

[]/products/Product%252dExample.html

But what it IS pulling in is:

[]/products/Product-Example.html

And this is causing the page to not work correctly.

Thanks!

Answer 1

the encodeURIComponent function will do what you want.

<script type="text/javascript">
document.write("<iframe src='http://www.facebook.com/plugins/like.php?href=" + encodeURIComponent( document.location.href ) + "&layout=standard&show_faces=false&action=like&font=verdana&colorscheme=light' frameborder=0></iframe>");
</script>
