【Javascript】String.format 格式化字串

	String.Format = function (format, Args) {
	var args = arguments;
	var replaceObj = {};
	var i = 1;
	if (typeof Args === "object") {
	for (var prop in Args) {
	format = format.replace(new RegExp("{" + prop + "}", "g"), Args[prop]);
	}
	return format;
	} else {
	if (args.length > 1) {
	for (; i < args.length; i++) {
	replaceObj["{" + (i - 1) + "}"] = args[i];
	}
	}
	return format.replace(/\{\d+\}/g, function (resourse) {
	return replaceObj[resourse];
	});
	}
	};

以前常利用c#的String.fomat來達到我想要的格式輸出
最近要用js來將某些資料更新到前端畫面，就寫了一下，不過還並不完整

String.Format("{0}, Javascript! {1}.", "Hi", "This is test");  //Hi, Javascript! This is test.

String.Format("{greeting}, {name}! {something}.", 
{
    greeting:"Hi",
    name:"Javascript",
    something:"This is test"
});//Hi, Javascript! This is test.
