Question

如何通过从我的odata服务中读取表格中的单个单元格来启用实时建议？

oTable.addColumn(new sap.ui.table.Column({
                template : new sap.m.Input({
                    value : column, // also works, its dynamic
                    textAlign : sap.ui.core.TextAlign.Center,
                    inputType : Text,
                    type : sap.m.InputType.Text,
                    showSuggestion : true,
                    liveChange : function() {
                        if (this.getValue().length > 0) {
                            var oModel = new sap.ui.model.json.JSONModel();
                            var value = this.getValue();
                            var serviceUrl = "/sap/opu/odata/SAP/XXXX_SRV/SuggestionsSet/?$filter=startswith(Key,'" + value + "')";
                            oModel.loadData(serviceUrl, null, false, "GET", false, false, null);

                            this.destroySuggestionItems();
                            for (var i = 0; i < oModel.oData.d.results.length; i++) {
                                this.addSuggestionItem(new sap.ui.core.Item({
                                    text: oModel.oData.d.results[i].Key,
                                }));
                            } // everything seems fine, but no Suggestion opens..


                        }
                    },
                }),
                visible : true,
            }));

请参阅explored example。但是，在你的情况下，模型是一个ODataModel，但这并不重要...... 正如您在示例代码中看到的那样，您也可以使用

showSuggestion="true"
suggest="handleSuggest"
suggestionItems="{/ProductCollection}"

然后在处理程序中执行此操作（也从示例中复制）：

handleSuggest: function(oEvent) {
    var sTerm = oEvent.getParameter("suggestValue");
    var aFilters = [];
    if (sTerm) {
        aFilters.push(new Filter("Name", sap.ui.model.FilterOperator.StartsWith, sTerm));
    }
    oEvent.getSource().getBinding("suggestionItems").filter(aFilters);
}

基本上你 - 创建一个或多个过滤器 - 获取 suggestionItems 聚合的绑定 - 在绑定上调用 .filter（...）并传递过滤器

无需手动编码（即GET请求等）。

以下是您（run via jsbin）的一个示例，见下文。在你的情况下，你所做的就是绑定到

suggestionItems="{path:'/SuggestionSet', templateShareable:false}">

在handleSuggest处理程序中，您将获得属于当前/相应输入字段的 SuggestionSet 的键属性的值，以便实例化新的Filter 。您可以从BindingContext获取 Key ，我猜...
