刷新表后未调用格式化程序

Question

通过SAPUI5应用程序在数据库中创建新记录后，未调用格式化程序。表格会刷新，新的数据可见，但按钮未正确启用。

以下是一些代码：

刷新代码：

this.byId("Table").getBinding("items").refresh();

格式化程序：

blockedFormatterFrom: function (value) {
        var datum = new Date();
        var dateString = value.substr(6, 4) + "." + value.substr(3, 2) + "." + value.substr(0, 2);
        if (new Date(dateString) < datum) {
            editable_from = false;
        } else {
            editable_from = true;
        }
        return value;
    },
    blockedFormatterTo: function (value) {
        var datum = new Date();
        var dateString = value.substr(6, 4) + "." + value.substr(3, 2) + "." + value.substr(0, 2);
        if (new Date(dateString) < datum) {
            editable_to = false;
        } else {
            editable_to = true;
        }
        return value;
    },
    editableFormatterEdit: function (value) {
        if (editable_from && editable_to) {
            return true;
        } else {
            return false;
        }
    },
    editableFormatterDelete: function (value) {
        if (editable_to) {
            return true;
        } else {
            return false;
        }
    }

如何刷新表格并运行格式化程序？

Answer 1

下面的这段代码是否解决了您的问题？

this.byId("Table").setModel(oModel);
this.getView().byId('Table').rerender();

我试图复制您的问题，但没有遇到。刷新模型后，列表将被更新，并且我的自定义格式器也会被触发。参见以下示例：

manifest.json

"dataSources": {
    "mainService": {
        "uri": "/sap/opu/odata/sap/ZHR_MY_WORKSCHEDULE_SRV/",
        "type": "OData",
        "settings": {
            "odataVersion": "2.0",
            "localUri": "localService/metadata.xml"
        }
    }
}
......
"models": {
    "": {
        "dataSource": "mainService",
        "settings": {
            "defaultCountMode": "Inline"
        }
    }
}

查看

<Page title="{i18n>title}">
    <headerContent>
        <Button icon="sap-icon://refresh" tooltip="Share" press="onRefresh" />
    </headerContent>
    <content>
        <List items="{/WorkSched_PendingSet}">
           <StandardListItem
              title="{EmpName}"
              description="{
                 path : 'Position',
                 formatter : '.formatter.fnFormatDescription'
              }"
              type="Active">
          </StandardListItem>
        </List>
    </content>
</Page>

控制器

return Controller.extend("com.demoDemo.controller.View1", {
    formatter : Formatter,

    onRefresh : function() {
        this.getView().getModel().refresh();
    }
});

Answer 2

您还可以共享XML视图吗？ 尝试使用 headers: { 'Access-Control-Allow-Origin': '*', "Content-type": "application/json; charset=UTF-8", 'mode':'no-cors', },

强制刷新

Answer 3

this.byId("Table").setModel(oModel);
this.getView().byId('Table').rerender();

将模型设置为表格并调用函数rerender（）
