How to embed an attribute value in a hyperlink within infoWindow/content/href

Question

I am very new to ArcGIS API for JavaScript so bare with me. I would like to use a value from an attribute such as a "name" to reference a text file within the content of an infoWindow such as: Name: " + attrs.Name + ".txt" where mainlink = "http://foobar.com/" end_of_link = attrs.Name + "/" + attrs.Name + ".txt" link = mainlink + end_of_link and the variable "link" is substituted above for "http://foobar.com/name1/name1.txt". Can someone help me with the syntax in the above reference using the link variable? Thanks.

setContent requires a string, it doesn't do substitution for you.

For more info, refer to our conceptual help. Specifically, the format info window content section. Lots of other great info pertaining to popup/info window content in that area as well.

Thanks a million Derek.;) So, I have something like this working on infoWindows throughout my code, but for some reason it is not working on others. Is this syntax correct? When this is not working, the link does not substitute the fields correctly, it just keeps it literal. Is there more documentation on creating links using fields this way? map.infoWindow.setContent("PDF");

To do this, you want to build an HTML string. If you want markup that looks like:link text and you have an attributes object that looks like: { "path": "some-web-server-folder", "file": "data" } You would do this: var anchor = "link text"; Managing those single and double quotes can get unwieldy. If you're building big strings, check out dojo.string.substitute to use templates which usually results in cleaner code.
