Try to fill xml combobox parameters with js controller

[Former Member]

Hi,

I have a view in xml.

In my view, I insert 2 combobox :

<Combobox id="combo1"

selectionChange = "onComboSel"

items="{

  path: '/CountryF4Set',

  filters: [{ path: 'ZCOMBO', operator: 'EQ', value1: '1' }]

  }"

  <items>

     <core:ListItem text="{ZTEXT}" key="{ZKEY}"> </core:ListItem>

  </items>

</Combobox>

<Combobox id="combo2"

selectionChange = "onComboSel"

enable='false'>

  <items>

     <core:ListItem text="{ZTEXT}" key="{ZKEY}"> </core:ListItem>

  </items>

</Combobox>

I want to know how add add value (retrieve from backend with path and filter) in my combo2 in function onComboSet ?

=> I want to translate :

items="{

  path: '/CountryF4Set',

  filters: [{ path: 'ZCOMBO', operator: 'EQ', value1: '1' }]

  }"

in javascript !

Thanks for your help

Hi Adeline Louise,

1. First create oDATA Class to fetch data from server to client side.

for ex:

new sap.ui.model.odata.ODataModel("

/sap/opu/odata/SAP/ZNASS_MYTEAM_SRV");

var model = new sap.ui.model.odata.ODataModel(serviceURL, true);//ZODATA_SRV_SPB_GWS

  var readRequestURL = oEvent.requestURL;

  model.read(readRequestURL, null, null, false, 

     function(oData, oResponse) {

  oDataModel = oData.d.results;

///////Simulation EXample

create read request to get record. inside success block, you might get this JSON format.

      var oDataModel = {"d":{"results":[{"__metadata":{"id":"http://w.corp:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793811')","uri":"http://w:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793811')","type":"ZODATA_SRV_SPB_GWS.CHN_SCType"},"ID":"160405691834793811","CA_STATUS_RAG":"A","CM_COUNT":"10"},{"__metadata":{"id":"http://w.corp:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793812')","uri":"http://w.corp:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793812')","type":"ZODATA_SRV_SPB_GWS.CHN_SCType"},"ID":"160405691834793812","CA_STATUS_RAG":"G","CM_COUNT":"23"},{"__metadata":{"id":"http://w.corp:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793813')","uri":"http://w:8015/sap/opu/odata/sap/ZODATA_SRV_SPB_GWS/CHN_SC('160405691834793813')","type":"ZODATA_SRV_SPB_GWS.CHN_SCType"},"ID":"160405691834793813","CA_STATUS_RAG":"R","CM_COUNT":"1"}]

}}

   });

2. Get this JSON record and put it into one variable. ( var oDataModel )

3. var components = new sap.ui.model.json.JSONModel(oDataModel );

  sap.ui.getCore().setModel(components);

4. create one dropdown

var oItemTemplate = new sap.ui.core.Item({

  key: "{CA_STATUS_RAG}",

  text: "{CM_COUNT}"

  });

       var oComboBox = new sap.m.ComboBox({

  items: {

  path: "/d/results",

  template: oItemTemplate,

  },

      });

Thanks,

this.byId("combo1").bindAggregation("items",{

path: '/CountryF4Set',

filters : [

new sap.ui.model.Filter('ZCOMBO', sap.ui.model.FilterOperator.EQ, '1')

]});
