javascript - toUpperCase() is not making the string upper case

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I don't know what I'm doing wrong; But somehow .toUpperCase() String-function is not working on my browser or do I get something wrong?

var string ="kjsdgfiIJHBVSFIU";
string.toUpperCase();
console.log(string);

.toUpperCase returns the upper-cased string. It is not an in-place modifier method.

string = string.toUpperCase();
