C# 將字符串轉為ऩ這種的 html實體編碼

 

1、字符串轉為html實體編碼

       private string GetHtmlEntities(string str)
        {
            string r = string.Empty;
            for (int i = 0; i < str.Length; i++)
            {
                r += "&#" + Char.ConvertToUtf32(str, i) + ";";
            }
            return r;
        }

 JS版

 function htmlentities(str)
 {
      var r = "";
      for( i=0; i<str.length; i++ )
      {
           temp = str.charCodeAt(i);
           r += "&#"+temp+";";
      }
     
     //  也可以用一句正則表達式解決
     // r = str.replace(/[\d\D]/g, function($0) { return "&#" + $0.charCodeAt(0) + ";"; });
     return r;
 }
