在擴展菲奧裏應用

Question

此排序是下面的代碼，我使用：

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); 
}, 

有什麼辦法，我們也可以通過文字我們傳遞的關鍵在oHeaderFooterOptions.oSortOptions對象的方式，以及如何我們是否獲得像aSortItems和sSelectedItemKey這樣的屬性，是否有這樣的API？

我們嘗試瞭解問題。請看下面的代碼：

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); 
},
