javascript - SAP UI5 - 无法从表中删除选定的行

Question

我有一个 View ，其中包含一个具有单选模式的表格，其工具栏中有一个用于删除所选行的按钮。

虽然当我按下按钮时，它会删除所有行。

我的代码:

查看文件:

<template data-controller-name="myapplication.myview2">
    <div data-sap-ui-type="sap.ui.table.Table" id="tb1" data-width="100%" data-title="Person Table"></div>
</template>

Controller 文件:

onInit: function() {
        try {
            var oTab = [
                        // the table content

                        ];
            var oToolbar = new sap.ui.commons.Toolbar();
            oToolbar.addItem(new sap.ui.commons.Button({text: "Delete selected row", 
                press: function() {
                    try {
                        var newTab = this.getParent().getParent();
                        var index = newTab.getSelectedIndex();
                        if (index == -1)
                            alert("No row selected");
                        else {
                            var currModel = newTab.getModel();
                            var selectedRow = newTab.getRows()[index];
                            newTab.removeRow(selectedRow);
                            currModel.setData({table: newTab});
                            newTab.bindRows("/table");                  
                        }
                    } catch (err) {
                        txt = "There was an error on this page.\n\n";
                        txt += "Error description: " + err.message + "\n\n";
                        txt += "Click OK to continue.\n\n";
                        alert(txt);
                    }
                }}));
            this.byId("tb1").setToolbar(oToolbar);
            this.byId("tb1").setVisibleRowCount(5);
            this.byId("tb1").setNavigationMode(sap.ui.table.NavigationMode.Paginator);

            // Columns definition should be HERE

            var oModel = new sap.ui.model.json.JSONModel();
            oModel.setData({table: oTab});
            this.byId("tb1").setModel(oModel);
            this.byId("tb1").bindRows("/table");

        } catch (err) {
            txt = "There was an error on this page.\n\n";
            txt += "Error description: " + err.message + "\n\n";
            txt += "Click OK to continue.\n\n";
            alert(txt);
        }
    },
// More functions....

有什么想法吗？

您需要从模型中删除行，而不是直接从表中删除行。
