actionscript-3 - Action Script 3 中是否有类似 printf 的东西？

Question

我搜索了一段时间，但没有在 Action Script 中找到类似 printf 的内容。

这使得生成格式化字符串有点困难。

Answer 1

Printf-as是一个可以处理这个问题的第三方库。 Here是 GitHub 存储库。从自述文件:

printf("You can also display numbers like PI: %f, and format them to a fixed precision, 
        such as PI with 3 decimal places %.3f", Math.PI, Math.PI);
// outputs: " You can also display numbers like PI: 3.141592653589793, 
// and format them to a fixed precision, such as PI with 3 decimal places 3.142"

它也适用于日期:

var date : Date = new Date();
printf("Today is %d/%m/%Y", date, date, date);
