Infragistics NetAdvantage jQuery API Reference

ig.JSONPDataSource

ig.JSONPDataSource_image

The JSONPDataSource extends the DataSource class and sets the responseDataType option to 'jsonp' by default. For more details on the JSONPDataSource component’s API, refer to the base DataSource component’s API documentation. Further information regarding the classes, options, events, methods and themes of this API are available under the associated tabs above.

The following code snippet demonstrates how to initialize the JSONPDataSource control.

    					var ds = new $.ig.JSONPDataSource({
                            type: "json",
    						dataSource: url, 
    						responseDataKey: "Records",
    		                filtering: {
    			                type: "remote",
    			                filterExprUrlKey: "filter",

      • applyToAllData

        Type:
        bool
        Default:
        true

        If the type of paging/sorting/filtering is local and applyToAllData is true, filtering will be performed on the whole data source that's present locally, otherwise only on the current dataView. if type is remote, this setting doesn't have any effect.

        Code Sample

         
                      var url = "http://services.odata.org/OData/OData.svc/Products?$format=json&$callback=?";

      • caseSensitive

        Type:
        bool
        Default:
        false

        Enables or disables case sensitive filtering on the data. Works only for local filtering.

        Code Sample

         
                        var url = "http://services.odata.org/OData/OData.svc/Products?$format=json&$callback=?";
                        jsonDs = new $.ig.JSONPDataSource( {
                            filtering: { 
                                type: "local",
                                caseSensitive: true,
                                applyToAllData: true
                            }, 
                            dataSource: url				
        			    }).dataBind();
                      
      • customFunc

        Type:
        object
        Default:
        null

        Can point to either a string or a function object. The parameters that are passed are 1) the data array to be filtered, 2) the filtering expression definitions. Should return an array of the filtered data.

        Code Sample

         
                            var ds;
        
                            var render = function (success, error) {

        			                    cond = "startsWith";
        
        			                    ds.filter([{

        			                    }], true);
        
        			                    $("#table1 tbody").empty();
        			                    $("#tableTemplate").tmpl(ds.dataView()).appendTo("#table1 tbody");
        		                    } else {

      • type

        Type:
        enumeration
        Default:
        remote

        filtering type. .

        Members

        • remote
        • Type:string
        • parameters will be encoded and it's up to the backend to interpred them from the response.
        • local
        • Type:string
        • the data will be filtered automatically client-side.

        Code Sample

                            var url = "http://services.odata.org/OData/OData.svc/Products?$format=json&$callback=?";
                            jsonDs = new $.ig.JSONPDataSource( {
                            type: "json",
                            filtering: { 
                                type: "local",
                                caseSensitive: true,
                                applyToAllData: true
                            },

    • id

      Type:
      string
      Default:
      ds

      Setting this is only necessary when the data source is set to a table in string format. we need to create an invisible dummy data container in the body and append the table data to it.

      Code Sample

       
                 var ds = $.ig.JSONPDataSource({
      	                id: "myId"
                      });
                
    • localSchemaTransform

      Type:
      bool
      Default:
      true

      If set to false will disable transformations on schema, even if it is defined locally in the javascript code.

      Code Sample

       
                  var url = "/demos/server/proxy.php?url=http://services.odata.org/OData/OData.svc/Products?$format=json";
      			ds = new $.ig.JSONPDataSource({
                      callback:render, 
                      dataSource: url, 
                      type: "json",
      			    localSchemaTransform: false, 
                      responseDataKey: "d",
      			    schema: {fields: [
                          {name : "Price"}, 
                          {name : "Name"}, 
                          {name: "Rating"}
                      ]}
                  });
      			
      			ds.dataBind();
                
    • outputResultsName

      Type:
      string
      Default:
      null

      This is the property in the dataView where actual resulting records will be put. (So the dataView will not be array but an object if this is defined), after the potential data source transformation.

      Code Sample

       
                      var render = function (success, error) {
      		                if (success) {
      			                $("#table1 tbody").empty();
      			                $("#tableTemplate").tmpl(ds.dataView()).appendTo("#table1 tbody");
      
      		                } else {
      			                alert(error);
      		                }
      	                }
                          
                      var ds;
                      $(window).load(function () {
      	                var url = "http://services.odata.org/OData/OData.svc/Products?$format=json&$callback=?";
      	                ds = new $.ig.JSONPDataSource({
      		                callback: render,
                              type: "json",
      		                dataSource: url,
      		                schema: {
      			                fields: [{
      				                name: "Name"
      			                }, {
      				                name: "Price"
      			                }, {
      				                name: "Rating"
      			                }],
      			                searchField: "d"
      		                },
      		                responseDataKey: "d",
      		                outputResultsName: "myOutputResultsName"
      	                });
      	                ds.dataBind();
                      });
                
    • paging

      Type:
      object
      Default:

  • &nbspdataBind

    .JSONPDataSource( "dataBind", [callback:string], [callee:object] );

    Data binds to the current data source data source
    databinding works using the following workflow:
    1. fire the databinding event
    2. based on the data source type (see analyzeDataSource()), do the following:
    3. if type is HtmlTable, parse the table and set the data and dataView respectively.
    if the type is Function, call it, apply Paging/Filtering/Sorting, and set this._dataView . If the developer wants to do his own paging, filtering or sorting
    in that case, then he should handle the PageIndexChanging and/or DataFiltering, and/or ColumnSorting client-side events, and cancel them.
    if no paging/sorting/filtering are enabled, use just this._data to save space
    if the data source is of type RemoteUrl, use jQuery's $.ajax API to trigger a remote request to the service. Use the param() API to encode the URL
    if the data source is invalid, throw an exception
    if the analyzed runtime data source type , that is, the result of analyzeDataSource(), is Unknown, check if
    the value of settings.type is set to XML or JSON. If string, eval for JSON, and parse for the XML to build the object ree
    4. now normalize/transform the data, if a schema is supplied. This inplies any additional data type conversion
    5. next, if OpType is Local, apply paging, sorting, and/or filtering to the data, and store the result in this._dataView
    6. fire the databound event

    example 2: [{fieldIndex : 1} , {fieldIndex : 2, expr: "a", cond : "contains"}]
    expr is the filter expression text , such as "abc", or a regular expression such as *test*
