如何結合重複的javascript

我確定這是一個非常基本的問題，但我剛剛開始學習JavaScript（過去總是使用PHP），並不能完全解決問題。我有基於用戶輸入執行計算的代碼，當jquery滑塊移動，文本框值改變或按下按鈕時結果更新 - 所有三個觸發器都會觸發相同的代碼，但我必須重複代碼三次，因爲它是如何被觸發的 - 有沒有辦法將它寫成一個代碼塊，而不是單獨的onchange，onclick和內置到滑塊查詢？對於以下長碼預先道歉...如何結合重複的javascript

如果你的問題是*我怎麼可以這樣寫更好的*，而不是*我怎麼能解決這個*？，http://codereview.stackexchange.com是爲這個問題設計的網站:)。 – Matt 2013-04-28 18:53:10

馬特 - 欣賞洞察力，不知道有codereview部分！一旦我將代碼拿到了我喜歡的地方，我會試試看。 – mvanmeter 2013-04-30 20:15:02

這個問題似乎是無關緊要的，因爲它涉及代碼審查。 – g00glen00b 2014-03-02 12:23:17

所以，你爲什麼不使用函數？像

var myApp={}; 
myApp.complicatedCalculation=function(parameter){/* YaddaYadda */}

所以每次，你需要它，你可以撥打：

myApp.complicatedCalculation(parameter)

謝謝莉莉絲 - 那有效。只是想知道爲什麼你使用'var myApp = {};'和'myApp.complicatedCalculation = function（parameter）{} ...'不能像你說的那樣簡單'var myApp = function（parameter）{/ * yaddayadda * /}'或者我錯過了什麼？ – mvanmeter 2013-04-30 20:15:44

不客氣。此外：使用變量myApp，它被初始化爲一個對象，然後用函數擴展是JS中的一種常見模式;它是JS的一種命名空間。因此，用於「myApp」的所有內容都位於此名稱空間下。更多情況下，您會看到使用var myApp = myApp ||進行初始化{}，這意味着沒有別的：如果myApp被定義使用它;如果不是，這裏是定義。 – 2013-04-30 21:59:41
