Action Script 3中有类似printf的东西吗？

Question

我搜索了一会儿但没有在Action Script中找到类似printf的东西.

这使得生成格式化字符串变得有点困难.

Answer 1

Printf-as是一个可以处理此问题的第三方库.这是GitHub回购.来自README:

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);

认为你可能正在寻找StringUtil.substitute()
