推荐答案

您无法更改大写锁定键是打开还是关闭.但是，您可以根据大写锁定键是打开还是关闭来更改Java脚本的输入字符串是小写还是大写.

You can't change whether the caps lock key is on or off. You can however change whether your input strings are lower or upper case with Javascript based on whether the caps lock key is on or off.

for (char in inputString) {
    if(capslock) { // do your caps lock detection here
        if(char === char.toUpperCase()) { // it's upper case
            char = char.toLowerCase();
        } else {
            char = char.toUpperCase();
        }
    }
}
