javascript - 在javascript中将字符串转换为句子大小写

Question

我希望输入的字符串无论大小写都应转换为句子大小写。

喜欢

hi all, this is derp. thank you all to answer my query.

转换为

Hi all, this is derp. Thank you all to answer my query.

Answer 1

我想出了这种正则表达式:

var rg = /(^\w{1}|\.\s*\w{1})/gi;
var myString = "hi all, this is derp. thank you all to answer my query.";
myString = myString.replace(rg, function(toReplace) {
    return toReplace.toUpperCase();
});
