Javascript中的Sprintf（字符串格式）

Posted 2021-02-27

Example:

`var result = "Hello {0}! This is {1}.".format("world","foo bar");`

Returns:

`"Hello World! This is foo bar."`

String.prototype.format = function(){
    var pattern = /{d+}/g;
    var args = arguments;
    return this.replace(pattern, function(capture){ return args[capture.match(/d+/)]; });
}
