Magento configurable.js - separatorIndex做什么？

Question

我想知道下面的代码是做什么的，因为我在类别列表视图中遇到了自定义可配置选择器+ AJAX预览的问题。

var separatorIndex = window.location.href.indexOf('#'); 
    if (separatorIndex != -1) { 
     var paramsStr = window.location.href.substr(separatorIndex+1); 
     var urlValues = paramsStr.toQueryParams(); 
     if (!this.values) { 
      this.values = {}; 
     } 
     for (var i in urlValues) { 
      this.values[i] = urlValues[i]; 
     } 
    } 

我得到的错误是Uncaught TypeError: Cannot read property 'config' of undefined

这只有当我在URL（分层导航）的哈希发生。

var separatorIndex = window.location.href.indexOf('#'); // Looks for index of # in url 
if (separatorIndex != -1) { // If # exists and index is set 
    var paramsStr = window.location.href.substr(separatorIndex+1); // Get everything after the # in url 
    var urlValues = paramsStr.toQueryParams(); // Transform to key value 
    if (!this.values) { // Don't know where this comes from? 
     this.values = {}; 
    } 
    for (var i in urlValues) { 
     this.values[i] = urlValues[i]; // Fill up the this.values with values from the substring after # 
    } 
}
