我在firebug中得到以下錯誤：不支持jQuery 1.6.2與操作錯誤「代碼：」9。首先可以有人告訴我這個錯誤的確切含義？其次，我正在做的是使用對話框來顯示一個表格，該表格很好顯示，但每當我點擊一個輸入字段時，就會觸發這個錯誤。我重視我的代碼，並會成爲一些指導感激：

找到如何解決它在我的一些情況。

在jQuery中源（未分）找到此塊：

if (document.documentElement.contains) { 
    Sizzle.contains = function(a, b) { 
     return a !== b && (a.contains ? a.contains(b) : true); 
    }; 

} else if (document.documentElement.compareDocumentPosition) { 
    Sizzle.contains = function(a, b) { 
     return !!(a.compareDocumentPosition(b) & 16); 
    }; 

} else { 
    Sizzle.contains = function() { 
     return false; 
    }; 
} 

，並添加的try-catch它爲什麼會發生，你可以在例外部分閱讀here行return !!(a.compareDocumentPosition(b) & 16);

if (document.documentElement.contains) { 
    Sizzle.contains = function(a, b) { 
     return a !== b && (a.contains ? a.contains(b) : true); 
    }; 

} else if (document.documentElement.compareDocumentPosition) { 
    Sizzle.contains = function(a, b) { 
     try { 
      return !!(a.compareDocumentPosition(b) & 16); 
     } 
     catch (e) { 
      return false 
     } 
    }; 

} else { 
    Sizzle.contains = function() { 
     return false; 
    }; 
}
