Hello,
I am attempting to work with the Javscript API do the following.
Enter an address (address 1), intersect a polygon, get an address (address 2) from that polygon and route a line between the resulting points.
I am trying to find the proper functionality in the API to support this processing.
I found the routing support in the sample on the directions app at Directions | ArcGIS API for JavaScript.
There is also an example for point in polygon search at Geoprocessing - Point in polygon search | ArcGIS API for JavaScript . Is there an basic example of this functionality available?
Does anyone have any example of reading attributes from a selected feature?
Thanks for your time!
Christopher,
I would just use a simple QueryTask to get the intersection of Address 1 geocode point with your polygon layer. The returned results of the QueryTask will have the attributes that you can read.
Robert, thanks for your help.
I am having difficulty with determining what classes to use and getting the results from the event.
I am trying to use a search object and get the data from the search results. I would then perform an intersection on the polygon layer and get the address.
I am trying to use a each object with no luck. Am I using the right classes and how do I get the results from the event?
var mySearch = new Search(
{
map: myMap
}, "searchDiv");
mySearch.startup();
//begin event handler
mySearch.on("search-results", function(e)
{
alert(e.results[0].toString());
}); //end call process results function); //end event handler
Christopher,
Try using:
mySearch.on("select-result", function (evt){ //Do something with the result feature console.info(evt.result.feature); });
Robert, thank you again. However, your code issues an error in javascript.
My code is below.
//begin event handler
mySearch.on("search-results", function(e)
{
console.info(e.result.feature);
}); //end call process results function); //end event handler
TypeError: Unable to get property 'feature' of undefined or null reference TypeError: Unable to get property 'feature' of undefined or null reference
The following code will produce a result but not very useful.
console.info(e.results[0].toString());
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
I can't seem to access the event object in the seach results to get the results.

Christopher,
You need to look care fully at the API documentation the returned parameters for "select-result" is different than "select-result" code that I provided.
Search | API Reference | ArcGIS API for JavaScript | event-search-results
Your code would have to be:
//begin event handler mySearch.on("search-results", function(e) { console.info(e.results); // This should return an array of results that have a extent and feature property }); //end call process results function); //end event handler
