For example, in this piece of code:
<a href="www.some.html" onclick="...">www.some.html</a>
What I have write instead of three dots if I want to store the url (www.some.html) in variable (var MyURL) after click on link?
When you click that link (and the onclick won't stop the default action) you will go to the link in href.
So to just store the link write this:
<a href="http://www.some.html" onclick="var a=this.href;return false">www.some.html</a>
the "return false" piece will stop the default action and prevent the browser from going to the url and you have a variable "a" with the value = "www.some.html"...
the variable you want is just this.href - you can test it by setting your onclick to alert(this.href). Note that the anchor will work better with a full URL, ie http://www.some.html
