The results of other tasks such as query, route.Values from one of the current web map feature.Task come from one or more of the below sources: Successful execution of the task, you must specify the values forĪll the required input parameters ( esriGPParameterTypeRequired) of The task page also has a help URL where you can find more information on the geoprocessing functionality, access, and use. The Task page lists all the task parameters and theirĭata types. To learn the parameters requirements of a task, copy and paste the task URL into the address bar of a webīrowser to open the Task page of the services directory. When executing a geoprocessing task, the webĪpplication must provide the parameter values for the geoprocessing GpTask.outSpatialReference=myMap.spatialReference Step 2: Set up task parameters myMap is assumed to be an instance of map container esri.map.

Set output spatial reference property to map's spatial reference. Since we will be using gpTask variable in other methods */ That is, declare the variable outside a function definition

* Step 1: Initialize Geoprocessing Task as a global variable. Add it along with other dojo.require statements. The server will return outputs in the spatial reference specified by the outSpatialReference property. Output spatial reference property of the geoprocessing task. This may cause unexpected behavior when drawing outputs. However, web applications assume the task outputs are in the same spatial reference as that of the map. Their outputs may be in a different spatial reference as well. May be in a different spatial reference and hence When initializing, be sure to set the outSpatialReference property of the geoprocessing task instance to the web map's spatial reference. The template for a geoprocessing task URL is Add the code below to your JavaScript application to initialize a geoprocessing task. To initialize a geoprocessing task, you must be aware of the task URL. Step 1: Initialize the geoprocessing task Using these four steps, you can successfully add geoprocessingįunctionality using the ArcGIS API for JavaScript. Use geoprocessing tasks in the ArcGIS API for JavaScript With the server, execute the task successfully, and visualize the These four steps allow the application to communicate To add a geoprocessing functionality providedīy a task in your web application, follow the four steps The ArcGIS API for JavaScript provides convenient objects and methods to access geoprocessing tasks and execute the functionality.
