的Javascript：代碼投入功能時，沒有得到執行

Question

我有這方面的工作的JavaScript代碼確實對init和resize一些調整大小：

(function (w) { 

    w.init = function() { 

    var w = window.innerWidth; 
    var h = window.innerHeight; 

    //resize_font; 
    var fs = parseInt(w/26); 
    document.body.style.fontSize = fs + "px"; 

    //resize_cover; 
    var logo = get_by_id("logo"); 
    var logo_height = logo.clientHeight; 
    var menu = get_by_id("menu"); 
    var menu_height = menu.clientHeight; 
    var cover_height = logo_height + menu_height; 
    var distance_top = (h - cover_height)/2.5; 

    var container = get_by_id("container"); 
    container.style.paddingTop = distance_top + "px"; 
    } 

    w.resize = function() { 

    var w = window.innerWidth; 
    var h = window.innerHeight; 

    //resize_font; 
    var fs = parseInt(w/26); 
    document.body.style.fontSize = fs + "px"; 

    //resize_cover; 
    var logo = get_by_id("logo"); 
    var logo_height = logo.clientHeight; 
    var menu = get_by_id("menu"); 
    var menu_height = menu.clientHeight; 
    var cover_height = logo_height + menu_height; 
    var distance_top = (h - cover_height)/2.5; 

    var container = get_by_id("container"); 
    container.style.paddingTop = distance_top + "px"; 
    } 
} 

現在我想重構代碼，用於調整字體和翻唱成一個函數，但 我無法讓它工作。我試過這個：

(function (w) { 

    w.init = function() { 
    var w = window.innerWidth; 
    var h = window.innerHeight; 

    resize_font; 
    resize_cover; 
    } 

    w.resize = function() { 
    var w = window.innerWidth; 
    var h = window.innerHeight; 

    resize_font; 
    resize_cover; 
    } 

    function resize_cover() { 
    var logo = get_by_id("logo"); 
    var logo_height = logo.clientHeight; 
    var menu = get_by_id("menu"); 
    var menu_height = menu.clientHeight; 
    var cover_height = logo_height + menu_height; 
    var distance_top = (h - cover_height)/2.5; 

    var container = get_by_id("container"); 
    container.style.paddingTop = distance_top + "px";   
    } 

    function resize_font() { 
    var fs = parseInt(w/26); 
    document.body.style.fontSize = fs + "px";   
    } 
} 

控制檯不顯示任何錯誤，但調整大小沒有發生。我究竟做錯了什麼？

Answer 1

你需要在init和resize事件函數中調用你的函數。 您有：

resize_font; 
resize_cover; 

您需要：

resize_font(); 
resize_cover(); 

一個函數的名稱就是對它的引用，這就是爲什麼你沒有看到任何錯誤。你現在有類似說法：

var x = 1; 
x; 

Answer 2

看起來你的問題是這樣的：

resize_font; 
resize_cover; 

我想你的意思

resize_font(); 
resize_cover(); 

Answer 3

這好像你忘了執行功能，剛纔提到了指針。

請嘗試更改：

resize_font; 
resize_cover; 

到

resize_font(); 
resize_cover();
