<a target="_self" onmouseout="hideTooltip()" onmouseover="showTooltip(event,'click on the name for additional details');return false" class="tip" href='<%=request.getContextPath()%>/index.jsp?page=myhome&type=details&appName=javascript:escape('<%=adMetricsVO.getApplicationName()%>')&Id=<%=bean.getID()%>'><%= bean.getName()%></a>

You cannot run JavaScript inside the href attribute -- it's not a JavaScript-aware attribute. — cdhowie

That's very wrong. (and impossible to do as you're attempting)

You should escape the getApplicationName() on the server.
You need to URL-encode it, then attribute-encode it.

That's not going to work because the Javascript interpreter won't be involved with the ordinary "click" behavior of the element. In other words, Javascript is never going to see that "href" value.

To make that work, you could either escape the application name on the server, or else put the URL together in a separate piece of Javascript that you wire up to the window "load" event, or something like that.

Alternatively you could have the "click" handled by a Javascript handler that makes the URL and reloads the page.
