Js 实现 C# Format方法
参考网友的, 挺好用的:
String.prototype.format = function (args) { if (arguments.length > 0) { var result = this; if (arguments.length == 1 && typeof (args) == "object") { for (var key in args) { var reg = new RegExp("({" + key + "})", "g"); result = result.replace(reg, args[key]); } } else { for (var i = 0; i < arguments.length; i++) { if (arguments[i] == undefined) { return ""; } else { var reg = new RegExp("({[" + i + "]})", "g"); result = result.replace(reg, arguments[i]); } } } return result; } else { return this; } }
使用方法有两种:
//两种调用方式 var template1="我是{0},今年{1}了"; var template2="我是{name},今年{age}了"; var result1=template1.format("loogn",22); var result2=template1.format({name:"loogn",age:22}); //两个结果都是"我是loogn,今年22了"
