如何将名称值传递给 SAP UI5 中的控制器？

Question

XML

table.bindItems({
                path: "/",
                template: new sap.m.ColumnListItem({
                    cells: [
                        new sap.m.Text({
                            text: "{account_name}"
                        }),
                        new sap.m.Button({
                            text: "Disconnect",
                            name:"{account_id}",
                            press: [that.handleButtonPress, this]
                        })
                    ]
                })
            });

JS

handleButtonPress: function (oEvent) {
}

这里我动态绑定一个 json 数据到一个 table。我在那里放了一个按钮。当我点击按钮时，我需要在控制器中获取该名称值。这个怎么做..？

将传递给按钮按下处理程序的上下文更改为 that，而不是 this，这是指您的控制器。即

table.bindItems({
            path: "/",
            template: new sap.m.ColumnListItem({
                cells: [
                    new sap.m.Text({
                        text: "{account_name}"
                    }),
                    new sap.m.Button({
                        text: "Disconnect",
                        name:"{account_id}",
                        press: [that.handleButtonPress, that]
                    })
                ]
            })
        });

并在您的控制器中：

handleButtonPress: function (oEvent) {
     console.log(this); // this is your controller.
     var source = oEvent.getSource();
     console.log(source) // this is your button.
     var oBindingObject = source.getBindingContext().getObject();
     console.log(oBindingObject.account_id);// will print the button text

}
