One huge advantage to JavaScript is the amount of code available online. And, with minor modifications, this code can be grafted into your own web service's functionality. But there is one operation I have been unable to find . Because it is so basic in nature I assume that it must be available somehere! What I am looking for is a JavaScript API that will zoom the viewer to an urban parcel after having first provided the street address (St no - St Name - St name Suf)

From that point one can acquire the parcel ID and any other basic information as would be found in an assessing map. It seems that there are several options to do the reverse - find a parcel once the parcel ID is found. But ususally the address is known and not the parcel number. If anyone can point me to such a site where the code might be available I will greatly appreciate it. Many thanks.

Geocode the address, use the lat,lng you get from that to search your parcel layer and then zoom to the result?

Do the parcel data contain the address?  If so you could run a query task against the parcel layer in the map service & then zoom the extent of the feature(s) in the returned featureset.

Thanks for this. I am quite new to JS, which is why I have been looking for something already done that I could check over. What you say sounds quite correct bt unsure how to run the query.

Sorry for the delay, I was out of the office all last week.  See the code below for a simple example.  It has an address harded coded but you could easily take the house # and street name from input boxes on the web page. 

Also look into the JavaScript reference & samples on http://resources.esri.com/arcgisserver/apis/javascript/arcgis/index.cfm?fa=home
