Uncaugth引用錯誤自定義事件不定義在文件ratchet

海我是新的phonegap和棘輪framework.I試圖加載外部腳本與push.js.這是我的JS文件內容Uncaugth引用錯誤自定義事件不定義在文件ratchet

function init(){ 
    document.addEventListener('deviceready', onDeviceReady, false); 

    function onDeviceReady(){ 

     alert("device ready for use"); 
     } 
     var checkPage = function(){ 

     alert("push"); 
     var scriptName; 
     var scriptsList = document.querySelectorAll('script.js-custom'); // Add a "js-custom" class to your script tag 
     for (var i = 0; i<scriptsList.length;i++) { 

      // Handle scripts in separate files by assigning the script file name to its id. 
      // We save it in a variable because the ".done" callback is asynchronous. 
      scriptName = scriptsList[i].id; // IMPORTANT: Only one loadable script per page! 
      $.getScript("js/" + scriptName) 
       .done(function (script, textStatus) { 
        eval(script); 
        alert("ok"); 
       }) 
       .fail(function(){ 
        alert("error"); 
       }); 

     } 


    }; 

    window.addEventListener('push', checkPage); 

    }

這裏是我的html文件

您的第二個html文件中沒有cordova。當你加載two.html時，瀏覽器會破壞前一頁和與之相關的所有腳本。你應該在單個頁面中做所有事情，我建議使用一個mvvm框架，比如angularjs，emberjs等。

所以，確切的說，你的第二個html沒有cordova，所以deviceready永遠不會被解僱。但是，對於第一個html，你有設備準備和棘輪參考。但是，在那裏，你沒有js-custom的sample.js引用。所以，在deviceready（在第一個html中）時，你的棘輪抱怨缺少js-custom引用。

這是因爲您的WebView實現中缺少window.CustomEvent。

添加此Polyfill並且它每次都有效。我發現在Mozilla開發者網絡的解決方案：

/* 
* Polyfill for adding CustomEvent 
* see : https://developer.mozilla.org/fr/docs/Web/API/CustomEvent 
*/ 

if (!window.CustomEvent) { // Create only if it doesn't exist 
    (function() { 
     function CustomEvent (event, params) { 
      params = params || { bubbles: false, cancelable: false, detail: undefined }; 
      var evt = document.createEvent('CustomEvent'); 
      evt.initCustomEvent(event, params.bubbles, params.cancelable, params.detail); 
      return evt; 
     }; 

     CustomEvent.prototype = window.Event.prototype; 

     window.CustomEvent = CustomEvent; 
    })(); 
}
