Question

这是我正在使用的代码：

getHeaderFooterOptions: function() {
    var that = this;

    var oHeaderFooterOptions = {
        sI18NMasterTitle: "MASTER_TITLE",
        buttonList: []
    };

    oHeaderFooterOptions.oFilterOptions = {
        onFilterPressed: jQuery.proxy(that.onShowFilter, that)
    };

    var sortItems = [];
    var sortText=null;
    var sortKey = null;
    var sortKey = "WiCreatedAt";
    sortItems.push({
        key: "WiCreatedAt",
        text: "Descending"
    });
    sortItems.push({
        key: "WiCreatedAt",
        text: "Ascending"
    });

    oHeaderFooterOptions.oSortOptions = {
        aSortItems: sortItems,
        sSelectedItemKey: "WiCreatedAt",
        onSortSelected: jQuery.proxy(that.handleSort, that)
    };

    return oHeaderFooterOptions;
},

handleSort: function(sSortKey) {
    //alert("msg");
    if (sSortKey === "WiCreatedAt" ) {
        oSorter = new sap.ui.model.Sorter(sSortKey,false);
    }

    else if (sSortKey === "WiCreatedAt"  ) {
        oSorter = new sap.ui.model.Sorter(sSortKey, true);
    }
    this.getList().getBinding("items").sort(oSorter);
},

我们有没有办法按照我们在oHeaderFooterOptions.oSortOptions对象中传递密钥的方式传递文本，我们如何获得像aSortItems和sSelectedItemKey这样的属性，是否有任何API？

我们试图了解这个问题。请看下面的代码：

getHeaderFooterOptions: function() {
    var that = this;

    var oHeaderFooterOptions = {
        sI18NMasterTitle: "MASTER_TITLE",
        buttonList: []
    };

    oHeaderFooterOptions.oFilterOptions = {
        onFilterPressed: jQuery.proxy(that.onShowFilter, that)
    };

    var sortItems = [];
    var sortText=null;

    sortItems.push({
        key: "Descending",
        text: "WiCreatedAt sorted descending"
    });
    sortItems.push({
        key: "Ascending",
        text: "WiCreatedAt sorted ascending"
    });

    oHeaderFooterOptions.oSortOptions = {
        aSortItems: sortItems,
        sSelectedItemKey: "WiCreatedAt",
        onSortSelected: jQuery.proxy(that.handleSort, that)
    };

    return oHeaderFooterOptions;
},

handleSort: function(sSortKey) {
    //alert("msg");
    if (sSortKey === "Ascending" ) {
        oSorter = new sap.ui.model.Sorter("WiCreatedAt",false);
    }

    else if (sSortKey === "Descending"  ) {
        oSorter = new sap.ui.model.Sorter("WiCreatedAt", true);
    }
    this.getList().getBinding("items").sort(oSorter);
},
