JavaScript slice() 使用 Github 站点在本地工作与在线工作不同

Question

I'm parsing text file using Javascript. On the lines I have slice() function, my code appear to behave differently on local host and online

for example

if(connection == 'local') {
     value = d.substring(split2, split3).substr(1).slice(0, -1);
}
else if(connection == 'online') {
     value = d.substring(split2, split3).substr(1);
}

However this piece of code solve it but I cannot understand the behavior, it seems like when I use my code online that are extra hidden characters on the text file or something

Answer 1

you can do

value = d.substring(split2, split3).substr(1).trim(); 

trim() should remove any spaces and Escape Sequences.
