No JSON data displayed in Table

Posted on Aug 16, 2016 at 09:51 AM 21 Views

Hey,

I try to use a table with JSON data, but my table is still after few attempts (using examples from internet) empty.

I hope you can find my mistake(s)

Here is my code:

<!DOCTYPE html>
<html>
<head>
       <meta http-equiv="X-UA-Compatible" content="IE=edge">
       <meta charset="utf-8">
       <title>Rechtschreibprüfung</title>
       <script
            id="sap-ui-bootstrap"
            src="https://cloudportaltrial-p1941901642trial.hanatrial.ondemand.com/ui5-dist/resources/sap-ui-core.js"
            data-sap-ui-theme="sap_bluecrystal"
            data-sap-ui-libs="sap.m"
            data-sap-ui-compatVersion="edge"
            data-sap-ui-preload="async"
            data-sap-ui-xx-bindingSyntax="complex"
            data-sap-ui-resourceroots='{
                 "sap.ui.demo.wt": "./"
            }'>
       </script>

       <link rel="stylesheet" type="text/css" href="style.css">

       <script>
            sap.ui.getCore().attachInit(function () {
            sap.ui.xmlview({
            viewName: "sap.ui.demo.wt.view.App"
                 }).placeAt("content");
            });
       </script>
</head>
<body class="sapUiBody" id="content">
    
</body>
</html>


<mvc:View

                      width = "auto"
                      class="sapUiResponsiveMargin">
                 </Button>
                 <Panel class="sapUiResponsiveMargin" width = "auto" id="panel2">
                      <headerToolbar>

                </Panel>
            </l:content>
       </l:VerticalLayout>
</mvc:View>


sap.ui.define([
  "sap/ui/core/mvc/Controller",
  "sap/m/MessageToast"
], function(Controller, MessageToast) {
  "use strict";
  return Controller.extend("sap.ui.demo.wt.controller.App", {
  checkText: function() {
  var here = this;
  here.getWhitelist();
  here.getCorrections();
  here.createSuggestionTable();
  },
  createSuggestionTable: function() {
  var oData={
         suggestionData:[{
             'WORD':"test1",
             'SUGGESTION':"...test..."
         },{
             'WORD':"test2",
             'SUGGESTION':"...test..."
         }]
  };
  var demoJSONModel = new sap.ui.model.json.JSONModel();
            demoJSONModel.setData(oData);
            sap.ui.getCore().getElementById("suggestionTable").setModel(demoJSONModel);
  }
  });
});

Thanks in advance 😊

      The controller may look like this:

      sap.ui.define(['sap/ui/core/mvc/Controller','sap/ui/model/json/JSONModel'],
     function(Controller, JSONModel) {
     "use strict";
     return Controller.extend("sap.ui.demo.wt.controller.App", {

     onInit: function () {
          this.model = new sap.ui.model.json.JSONModel({
               suggestionData:[]
          });
          this.getView().setModel(this.model);
     },

     checkText: function() {
          // this.getWhitelist();  
          // this.getCorrections();
          this.updateSuggestionData();  
     },  

     updateSuggestionData: function() {
          var aSuggections = [{  
                         'WORD':"test1",  
                         'SUGGESTION':"...test..."  
                    },{  
                         'WORD':"test2",  
                         'SUGGESTION':"...test..."  
                    }];
          this.model.setProperty("/suggestionData", aSuggections);
     }

     });
});

      AND your view: line 11 should be (start with dot)

      press=".checkText"
