How to implement TreeTable in sapui5

问题:

i have a model like this

[ {"name":"Main 1","description":"main1 Description",
         "children": [{
               "name": "SUB 1",
               "description": "SUB 1 Description",
               "children":[
                    {
                        "name": "SUB 1.1",
                        "description": "SUB 1.1 Description"
                    },
                    {
                        "name": "SUB 1.2",
                        "description": "SUB 1.2 Description"
                    }         ]
                }],
                "parent":[{"name": "parent sub"}]
            },
   {"name":"Main 2","description":"main2 Description",children:[],parent:[]},
   {"name":"Main 3","description":"main3 Description",children:[],parent:[]},
   {"name":"Main 4","description":"main4 Description",children:[],parent:[]}
 ]

and i want to display name and description property. The contents in the "children" property should be a sub-level in the row, and i don't want to display "parent" content in this tree table. how can i restrict "parent" property from the tree table.

回答1:

The sap.ui.model.ClientTreeBinding used by the TreeTable with a JSONModel or XMLModel supports the parameter arrayNames. This parameter expects an array of the model property names that will create a sublevel (if containing an object).

So in your example you should use something like this:

treeTable.bindRows({path: '/pathToData', parameters: { arrayNames: ['children'] }});

or in XMLView:

<TreeTable rows="{path: '/pathToData', parameters: { arrayNames: ['children'] } }" >
...
</TreeTable>

Theres not much to find in the documentation about this except for one example. You can find the source for the example in the openui5 github.

Try This Should Work

var oData={
     "children":[ 
               {"name":"Main 1","description":"main1 Description", "children": [], "parent":[]},
               {"name":"Main 2","description":"main2 Description","children":[],parent:[]},
               {"name":"Main 3","description":"main3 Description","children":[],parent:[]},
               {"name":"Main 4","description":"main4 Description","children":[],parent:[]}
           ]
   };

var oTable = new sap.ui.table.TreeTable({
    columns: [
        new sap.ui.table.Column({label: "Name", template: "name"}),
        new sap.ui.table.Column({label: "Description", template: "description"})
    ],
    selectionMode: sap.ui.table.SelectionMode.Single,
    enableColumnReordering: true,
    expandFirstLevel: true,
    });

var oModel = new sap.ui.model.json.JSONModel();
oModel.setData(oData);
oTable.setModel(oModel);
oTable.bindRows("/children");
