# Anchor Links

## Metadata_End
Anchor links are hyperlinks whose URL contains: An anchor (URL followed by hash mark "#" followed by fragment identifier) or a hostname from the `onsitedoms` array.

If enabled, an event handler function is added for all links that are Anchors. The `onsitedoms` array is a comma-separated list of file domain names or a regular expression, which is used to determine if a link is "on domain". 

**Example**

Suppose the onsite domain field contains: 
`"localhost,webtrends.corp"`

Page contains the following named link:

`<a name=TopOfPage>Top of Page</a>`

Page contains the following hyperlink:

`<a href="#TopOfPage">Go to top</a>`

Clicking the link generates the following parameters: 



`DCS.dcssip=tagbuilder.webtrends.com`
`DCS.dcsuri=/Help/EventTracking/Anchor.aspx#TopOfPage`
`WT.ti=Anchor:#TopOfPage`
`WT.dl=21`

**Defining the onsitedoms parameter**

 The `onsitedoms` config parameter allows you to define what domains will be considered "on domain". For example, if you want to track off-site links from the product site yourcompanyshopping.com, and you enable off-site link tracking, you can ensure that links to your branding site continue to be tracked as on-site links by setting the onsitedoms config parameter to `yourcompanyshopping.com`,`yourbrand.com`.

**JavaScript Example:**

```java
window.webtrendsAsyncInit = function () {
        var dcs = new Webtrends.dcs();
        dcs.init( {
                dcsid: "dcs12345610000wocrvqy1nqm_123p",
                anchor : true,
                onsitedoms:"webtrends.com,webtrendssupport.com"
        });
        dcs.track();
        }
```
