JavaScript對象刪除特定鍵值

-4

upload: { 
    name: "upload", 
    url: "/upload", 
    controller: "invoicesCtrl", 
    templateUrl: "./views/invoices.html", 
    resolve: "resolveUrl('./compiled/invoices_app.js')" 
    }, 
    invoices: { 
    name: "invoices", 
    url: "/invoices", 
    controller: "invoicesCtrl", 
    templateUrl: "/invoices/views/invoices.html", 
    resolve: "resolveUrl('/invoices/app/js/compiled/invoices_app.js')" 
    }

只是爲了解決鍵值，其他必須是字符串。有沒有這個replace函數的任何正則表達式？預期的結果：

upload: { 
    name: "upload", 
    url: "/upload", 
    controller: "invoicesCtrl", 
    templateUrl: "./views/invoices.html", 
    resolve: resolveUrl('./compiled/invoices_app.js') 
    }, 
    invoices: { 
    name: "invoices", 
    url: "/invoices", 
    controller: "invoicesCtrl", 
    templateUrl: "/invoices/views/invoices.html", 
    resolve: resolveUrl('/invoices/app/js/compiled/invoices_app.js') 
    }

假設你正在使用JavaScript，可能重複：http://stackoverflow.com/questions/19156148/i-want-to-remove-double-quotes-from-a -串。 –

@SeanPerkins那不是我所期望的 – AndreFontaine

如果我正確理解你的問題，你想爲'resolve'的當前值運行'eval'的結果賦予'resolve'嗎？ – ndn

當你說去除雙引號和唯一的雙quoes在resolve是字符串字面終結，你說你想在某個時候被稱爲所謂的resolveUrl的JavaScript函數，那resolve應該是那個調用的結果？

在這種情況下，你可以這樣做：

// iterate through all properties of myObject, assuming it is a flat 
// object containing upload and invoices from your code 
Object.keys(myObject).forEach(function(key) { 

    if(myObject[key].hasOwnProperty('resolve')) 
     myObject[key].resolve = eval(myObject[key].resolve); 

});

如果你知道它永遠是一個resolveUrl調用，它會更安全，只是讓原有的屬性包含字符串值 - 例如。 resolve: '/invoices/app/js/compiled/invoices_app.js' - 然後手動調用resolveUrl：

if(myObject[key].hasOwnProperty('resolve')) 
    myObject[key].resolve = resolveUrl(myObject[key].resolve);
