how to access angularjs callback result jsonp

Question

I have a WMS query with url like this.

http://giswebservices.massgis.state.ma.us/geoserver/wms?VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=massgis:GISDATA.ACECS_POLY&SRS=EPSG:26986&BBOX=11830.0,776202.9449152543,348201.0,961492.0550847457&WIDTH=708&HEIGHT=390&INFO_FORMAT=text/javascript&FEATURE_COUNT=10&QUERY_LAYERS=massgis:GISDATA.ACECS_POLY&X=120&Y=109&FORMAT&STYLES=&SERVICE=WMS

This url returns JSON result parseResponse( ...json...)

I want to create angularjs $http jsonp but it did not work.

function appCtrl($scope, $http){
    function parseResponse(data) {
        $scope.data = data
    } 

    var httpOptions = {
        url: "http://giswebservices.massgis.state.ma.us/geoserver/wms?VERSION=1.1.1&LAYERS=massgis:GISDATA.ACECS_POLY&SRS=EPSG:26986&BBOX=11830.0,776202.9449152543,348201.0,961492.0550847457&WIDTH=708&HEIGHT=390&INFO_FORMAT=text/javascript&FEATURE_COUNT=10&QUERY_LAYERS=massgis:GISDATA.ACECS_POLY&X=120&Y=109&FORMAT&STYLES=&SERVICE=WMS",
        method: "JSONP",
        params : {
            REQUEST: 'GetFeatureInfo',
        },
    };

    $http(httpOptions).
        success(function(data){
            console.log(data);
            $scope.data = data;
        }).
        error(function(data){
            console.log(data);
        });
}

This gives error " parseResponse is not defined " But I defined that function

Answer 1

You can try set format_options in params, Because angularjs default callback function name is JSON_CALLBACK

var httpOptions = {
    url: "http://giswebservices.massgis.state.ma.us/geoserver/wms?VERSION=1.1.1&LAYERS=massgis:GISDATA.ACECS_POLY&SRS=EPSG:26986&BBOX=11830.0,776202.9449152543,348201.0,961492.0550847457&WIDTH=708&HEIGHT=390&INFO_FORMAT=text/javascript&FEATURE_COUNT=10&QUERY_LAYERS=massgis:GISDATA.ACECS_POLY&X=120&Y=109&FORMAT&STYLES=&SERVICE=WMS",
    method: "JSONP",
    params : {
        REQUEST: 'GetFeatureInfo',
        format_options: 'callback: JSON_CALLBACK'
    },
};

Here is how to access your AngularJS callback result using jsonp :

http://jsfiddle.net/jCUSh/138/

function WMSCtrl($scope, $http) {
    $scope.nums = [1,2,3]
    $scope.data = null;
    $scope.get_data = function() {
      var url2 = 'http://giswebservices.massgis.state.ma.us/geoserver/wms?VERSION=1.1.1&LAYERS=massgis:GISDATA.ACECS_POLY&SRS=EPSG:26986&BBOX=11830.0,776202.9449152543,348201.0,961492.0550847457&WIDTH=708&HEIGHT=390&INFO_FORMAT=text/javascript&FEATURE_COUNT=10&QUERY_LAYERS=massgis:GISDATA.ACECS_POLY&X=120&Y=109&FORMAT&STYLES=&SERVICE=WMS'
      $http.jsonp(url2, {params : {REQUEST: 'GetFeatureInfo'}});
    }

    window.parseResponse = function(data) {
      $scope.data = data
    }
}

I took off a vital param on the url (which was REQUEST=GetFeatureInfo ) and included it in the params argument on the jsonp function call to show an example of how the params arguments is passed.
