Question

我正在玩html5 LeanBack播放器，它在页面上只有它的javascritpts时效果很好。但是，如果我将这些javascript文件添加到rails 3项目，那么我在LeanBack Player的javascript文件中会出错：

Uncaught TypeError: Object function each(iterator, context) {
  var index = 0;
  try {
    this._each(function(value) {
      iterator.call(context, value, index++);
    });
  } catch (e) {
    if (e != $break) throw e;
  }
  return this;
} has no method ‘split’

在函数LBPlayer.prototype.resolveTextPlainSubs。

中

我猜这是因为与rails中的原生Prototype冲突，但我不知道如何解决它。感谢

事实上，它与Array.prototype

的原型延伸相冲突

// leanbackPlayer.js @941
srt = srt.split('\n\n');
var i = 0; var isSub = false;
this.vars.subs[lang] = {};
this.vars.subs[lang].label = {};
this.vars.subs[lang].label = label;
this.vars.subs[lang].track = {};

// Error: using for in over an array is just stupid
//        not even using hasOwnProperty is outright pitiful
for(var s in srt) { 

    // this will also yield `each` but that's a function which has no .split() method
    var st = srt[s].split('\n');
    var time; var j;
    if(st.length >= 2) {
        var t = "";

为了解决这个问题，您应该使用简单的for循环替换for(var s in srt)：

for(var e = 0, el = srt.length; e < el; e++) {
    var st = srt[e].split('\n');
    var time; var j;
    if(st.length >= 2) {
        var t = "";
        ...
}
