replace() doesn't work in xsjs

Here is the code written in test.xsjs file.

However, when I access this test.xsjs file through the Chrome, string didn't change to "adcd". It seems repalce() can't work in the hana environment.

I tested the replace() function in other environment, such as console in Chrome, they all run perfectly.

Thanks, let's discuss and discover why replace() runs like this.
