CSS文法高亮及代碼格式化的Regex匹配

CSS文法高亮及代碼格式化的Regex匹配

prototype擴充已有的Javascript對象：

String.prototype.trim = function(){return this.replace(/^s+|s+$/g, "");}

 

Getter唯讀屬性器：

    get EndlineMatcher()
        {
            return /n|r|rn/g;
        },

 

String.replace方法接受函數作為參數：

function HtmlEncode(original)
{
    var result =
        original.replace(/n|r|rn| {2,}/g
                , function ($0)
                    {
                        if($0[0] == " ") return TextFormat.Space($0.length);
                       
                        return "<br />" + $0;
                    }
                );
    return result;
}

 

使用數組進行字串重複：

    Space: function(num)
        {
            var times = parseInt(num);
            times = (times == NaN? 1:times+1); // times+1 length array has times intervals
           
            return new Array(times).join("&nbsp;");
        }
