Find and Identify Alert for No Records

Question

I am trying to recreate the Show Find Task results in DataGrid

http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples_start.htm#jssamples/find_map_datagrid.html

everything works fine, but i want to add an alert/message when no records are found. Seems like a simple task but i cannot figure it out?

Any help would be great

Thanks to both or you for your response.

The results.length worked great.

var query = (qu).split(' ').join('%'); if (query == '') { dojo.byId('parcel_search_info').innerHTML = 'You must enter a search value. Try again.' } else if (new String(query).length < 3) { dojo.byId('parcel_search_info').innerHTML = 'Searchs must contain at least 3 characters. Try again.' } else { dojo.byId('parcel_search_info').innerHTML = '

Searching...'; var qt = new esri.tasks.QueryTask(config.parcelQueryUrl + '?token=' + config.app.token); var q = new esri.tasks.Query(); q.returnGeometry = true; q.outFields = config.parcelQueryOutFields; q.where = "UPPER(PID) like '%" + query.toUpperCase() + "%' or UPPER(ADDRESS) like '%" + query.toUpperCase() + "%' or UPPER(OWNER) like '%" + query.toUpperCase() + "%'"; qt.execute(q, function(results) { if (results.features.length == 0) { dojo.byId('parcel_search_info').innerHTML = 'Sorry, but your search did not return any parcels. Try again.' } else if (results.features.length > 120) { dojo.byId('parcel_search_info').innerHTML = 'Sorry, but your search returned too many parcels. Try again.' } else { //build grid } }) } [HTML]

Enter Parcel ID (PID), address or owner

[/HTML] This is a query, but the same principle. Other point of info options include a dialog, tooltip, js alert, etc. I saw a pretty cool one the other day that displayed info in the textbox itself with different colored text.

Hi pjkielty,

"results.length" will give you how many results are fetched from the query.So you can check this condition if the results are zero then you for your interested and sweet alert message.
