ArcGis Javascript Split/cut polyline

Vakhtang_Zubiashvili — Tue, 19 Nov 2019 07:16:41 GMT

Hi Guys,

I ma looking for JavaScript sample to split/cur polyline in ArcGis JavaScript API.

I found one sample but it did not work for me.

I tried to do something using Geometry but failed.

If you have some code share Please.

Thank you.

Could you explain a bit more about what you are trying to accomplish, and post the code that you tried? Also, which version of the JS API are you using?

I would create a geo - processing(python) tool like erase on the server and host it.

Once hosted I will call the tool in my javascript code.

Here is the python tool box code:

import arcpy
from arcpy import env
env.workspace=sys.path[0]+"/test.gdb"
env.overwriteOutput=True

class Toolbox(object):
    def __init__(self):
        """Define the toolbox (the name of the toolbox is the name of the
        .pyt file)."""
        self.label = "Toolbox"
        self.alias = ""

# List of tool classes associated with this toolbox
self.tools = [_Erase]

class Model_Erase(object):
    def __init__(self):
        """Define the tool (tool name is the name of the class)."""
        self.label = "_Erase"
        self.description = ""
        self.canRunInBackground = False

    def getParameterInfo(self):
        # Input Features parameter
        Input_Feature_Line = arcpy.Parameter(
            displayName="Input Feature",
            name="Input_Feature_Line",
            datatype="DEFeatureClass",
            parameterType="Required",
            direction="Input")

        Input_Feature_Line.filter.list = ["Point","Polyline","Polygon"]

        Input_Erase_Layer = arcpy.Parameter(
            displayName="Erase Feature",
            name="Input_Erase_Layer",
            datatype="DEFeatureClass",
            parameterType="Required",
            direction="Input")

        Input_Erase_Layer.filter.list = ["Point","Polyline","Polygon"]

        Output_Feature_Layer = arcpy.Parameter(
            displayName="Intersect Output",
            name="Intersect_Layer",
            datatype="GPFeaturelayer",
            parameterType="Derived",
            direction="Output")

        parameters = [Input_Feature_Line, Input_Erase_Layer,Output_Feature_Layer]

        return parameters

    def isLicensed(self):
        """Set whether tool is licensed to execute."""
   arcpy.CheckOutExtension("Spatial")
   return True

    def updateParameters(self, parameters):
        """Modify the values and properties of parameters before internal
        validation is performed. This method is called whenever a parameter
        has been changed."""
        return

    def updateMessages(self, parameters):
        """Modify the messages created by internal validation for each tool
        parameter. This method is called after internal validation."""
        return

    def execute(self, parameters, messages):
        """The source code of the tool."""
   Input_Feature_Line = parameters[0].valueAsText
   Input_Erase_Layer = parameters[1].valueAsText

   if Input_Feature_Line == '#' or not Input_Feature_Line:
       Input_Feature_Line = sys.path[0]+"/test.gdb/polygon_area_buffer_1" # provide a default value if unspecified

if Input_Erase_Layer == '#' or not Input_Erase_Layer:
Input_Erase_Layer = sys.path[0]+"/test.gdb/Deployment" # provide a default value if unspecified

   # Local variables:
   #out_feature_class="%SCRATCHWORKSPACE%\\Erase_output.shp"
   out_feature_class="in_memory/out_feature_class"
   cluster_tolerance = "#"

   # Process: Erase
   arcpy.Erase_analysis(Input_Feature_Line, Input_Erase_Layer, out_feature_class, cluster_tolerance)
   parameters[2].value = out_feature_class
   print "DONE"

   return

Sorry, not sure how to help. It would be helpful to share your JavaScript code, JS API version, and any Console error messages.
