Im trying to get the character after my string, I am using the bellow code but it dose not seem to work.
Input value: fileinput-1
Expected result: 1
Any ideas. This is my code:
str = element.id;
str.substr(str.indexOf('-') + 1);
console.log(str);
index = str;
The problem is that you are not doing anything with the result of the substr call. So the value of str is not being updated.
You need to assign the result back to str, like this:
str = str.substr(str.indexOf('-') + 1);
substr back to str.
Get Last character of String in angular?? not get the all char's after the -.
"get the character after my string"... also, the code suggests all characters after the hyphen. That means, 2 bits of information that indicate it should be characters after the hyphen, and only 1 bit of information it should be the last character. If you think all the way back to pre-school you will remember that 2 is greater than 1.... I appreciate that may have been a long time ago so I understand why you might be confused. Not to mention the OP accepted my answersubstr() returns a string, you should catch it like this:
str = str.substr(str.indexOf('-') + 1 , 1);
or
var newstr = str.substr(str.indexOf('-') + 1, 1);

try this with substr() or slice() one.

// or use slice
var res= text.slice(-1);
