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"
