[Former Member]

Hello experts,

    I have a question,how to get the xpath corresponding to delete button in columnListItem?

    what I want is when click delete button in item line,delete the item in table and delete the json item corresponding to table item.

    I have done with add item function:handleAddItem,but I don't know how to delete.

View.xml

<Table id="createItems" headerText="" items="{new>/Items}" >

  <columns>

  <Column>

  <header hAlign="Center" >

  <Label text="{i18n>PreqItem}" />

  </header>

  </Column>

  <Column hAlign="Center" >

  <header>

  <Label text="{i18n>Quantity}" />

  </header>

  </Column>

  <Column hAlign="Center" >

  <header>

  <Label text="{i18n>DelivDate}" />

  </header>

  </Column>

  <Column hAlign="Center" >

  <header>

  <Label text="{i18n>ShortText}" />

  </header>

  </Column>

  <Column hAlign="Right" width="3em">

  <header>

  <Button icon="sap-icon://add" press="handleAddItem" />

  </header>

  </Column>

  </columns>

  <ColumnListItem type="Navigation" press="handleLineItemPress" >

  <cells>

  <Input type="Text" placeholder="{i18n>PreqItem}" value="{new>PreqItem}" />

  <Input type="Text" placeholder="{i18n>Quantity}" value="{new>Quantity}" />

  <Input type="Text" placeholder="{i18n>DelivDate}" value="{new>DelivDate}" />

  <Input type="Text" placeholder="{i18n>ShortText}" value="{new>ShortText}" />

  <Button icon="sap-icon://delete" press="handleDeleteItem" />

  </cells>

  </ColumnListItem>

  </Table>

controller.js

			handleAddItem : function(evt) {
				var view = this.getView();
				var bindingContext = view.getBindingContext("new");
				var path = bindingContext.getPath();
				var object = bindingContext.getModel().getProperty(path);
				object.Items.push({Accounts : [], ServiceLines : [], TextLines : []});
				bindingContext.getModel().setProperty(path, object);
			},

handleDeleteItem : function(evt) {

},

binding json:

Now I know how to get the json path

handleDeleteItem : function(evt) {

      var sPath = evt.getSource().getBindingContext('new').getPath();

      alert(sPath);

  },

But How to delete node from JsonModel using jsonpath sPath?
