javascript - escape & in url

How can I escape & (ampersand) in url with the correct replacement in the jQuery function. I have tried

.replace("/&/g", "&amp;")  
.replace("/&/g", "%26") 
.replace("/&/g", "\&")

But nothing is working.

If anyone has idea please share with me.

Thanks

.replace(/&/g, "%26") should work if your JS is external. If it's embedded in your HTML, then you probably need to escape the & as &. But, use encodeURIComponent instead of reinventing the wheel. – Ateş Göral Commented Jun 21, 2010 at 18:07

If you need to just escape a URL, I remend using a JavaScript function such as encodeURIComponent.

Try the URLEncode plugin: http://plugins.jquery./project/URLEncode

Stumbled on this old posting looking for something else. Just wanted to add that the original poster's question had to do with asking why

string.replace("/&/g", "&amp;")

wasn't working. The appropriate syntax for this should have been:

string.replace(/&/g, "&amp;")

The search token, as it was intended to be a regex, needs to be a regex and not a string.
