此项目中用到的Javascript偏门知识
prototype扩展已有的Javascript对象:
String.prototype.trim = function(){return this.replace(/^\s+|\s+$/g, "");}
Getter只读属性器:
get EndlineMatcher()
{
return /\n|\r|\r\n/g;
},
String.replace方法接受函数作为参数:
function HtmlEncode(original)
{
var result =
original.replace(/\n|\r|\r\n| {2,}/g
, function ($0)
{
if($0[0] == " ") return TextFormat.Space($0.length);
return "<br />" + $0;
}
);
return result;
}
使用数组进行字符串重复:
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(" ");
}
