删除多行(sap.ui.table.Table)
删除多行(sap.ui.table.Table)
提问于 2018-01-25 04:47:13
我在SAPUI5表上工作，我已经创建了一个从表中删除选定行的功能，但当我选择删除多个行时，它删除了错误的行。虽然第一个选定行被正确删除，但其他行却没有被删除。
fDeleteRow: function(oEvent) {
var oTable = this.getView().byId("tbl");
var data = oTable.getModel();
var selRowCount = oTable._oSelection.aSelectedIndices.length;
var Flag = false;
for (var i = 0; i < selRowCount; i++) {
var rowNum = oTable._oSelection.aSelectedIndices[i];
data.oData.splice(rowNum, 1);
data.oData.refresh();
Flag = true;
}
if (Flag) {
var oModelJson = new sap.ui.model.json.JSONModel();
oModelJson.setData(data.oData);
oTable.unbindColumns();
oTable.unbindRows();
oTable.setModel(oModelJson);
oTable.bindRows("/");
}

下面是一个http://jsbin.com/ducuyah/edit?html,js,output示例
您需要先反转选定的索引，然后才能进行拼接。请不要在表中使用私有成员
var oTable = new sap.ui.table.Table({
rows: '{/d/results}',
title: new sap.m.Button({
icon: 'sap-icon://delete',
press: function() {
var oModel = oTable.getModel();
var oData = oModel.getProperty('/d/results');
var reverse = [].concat(oTable.getSelectedIndices()).reverse();
reverse.forEach(function(index) {
oData.splice(index, 1);
});
oModel.refresh();
oTable.setSelectedIndex(-1);
}
}),
columns: [
new sap.ui.table.Column({
width: '100px',
label: new sap.ui.commons.Label({text: "District Name"}),
template: new sap.ui.commons.TextView({text:"{District}"})
}),
new sap.ui.table.Column({
width: '80px',
label: new sap.ui.commons.Label({text: "County"}),
template: new sap.ui.commons.TextView({text:"{County}"})
})]
});
var model = new sap.ui.model.json.JSONModel({
d: {
results: [
{ District: "D1", County: "C1"},
{ District: "D2", County: "C2"},
{ District: "D3", County: "C3"},
{ District: "D4", County: "C4"},
{ District: "D5", County: "C5"},
{ District: "D6", County: "C1"},
{ District: "D7", County: "C2"},
{ District: "D8", County: "C3"},
{ District: "D9", County: "C4"},

{ District: "D12", County: "C3"},
{ District: "D13", County: "C4"},
{ District: "D14", County: "C5"},
]
}
});
oTable.setModel(model);
oTable.placeAt('content');
oTable.setFirstVisibleRow(10);
oTable.setSelectedIndex(10);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
