Flash AS3算大写字母？

Question

如何使用flash as3计算字符串中的大写字母数？

例如

var thestring = "This is The String";

应该返回int 3

谢谢

Answer 1

// Starting string.
var thestring:String = "This is The String";

// Match all capital letters and check the length of the returned match array.
var caps:int = thestring.match(/[A-Z]/g).length;
trace(caps); // 3
