discard count of \n in a string while using string.length in Javascript

Question

" HelloWorld " consists of 10 characters

I have a string as

var temp = "Hello\\nWorld"

When I use temp.length it returns 11 as it counts \\n as a character. How do I only count characters?

Answer 1

You have to firstly remove the \\n:

temp.replace(/\n/g, '').length

String will still be:

temp = "Hello\nWorld"

Answer 2

Use match() to get count of line breaks and subtract from total length

var str = 'Hello\nWorld\n';
var breaks =str.match(/\n/g);
var count = str.length - (breaks ? breaks.length : 0);

alert(count)

Answer 3

替代解决方案

temp.match(/\w/g).length;

Answer 4

"Hello\\nworld" returns 11 characters because \\n also is a character. so if you want to count how much characters in string, you need to remove any \\n or \\s firstly in .length
