jQuery: How to trim new line and tab characters between words

Question

Hi I am getting new line(\\n) and tab(\\t) characters between words and I was trying to trim those by using $.trim() function but its not working. So can anyone have some solution for this type of problem.

Ex:

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str));

the above code is not working.

Answer 1

str.replace(/\s+/g, " "); //try this

reference replace

\\s matches any newline or tab or white-space

Answer 2

You can do this:

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str.replace(/[\t\n]+/g,' ')));
// results is  "Welcome To Beautiful World"

Answer 3

That is expected. trim only takes care of leading and trailing whitespace.

Instead, use

str.split(/\s/).join(' ');

In your example, this returns

"Welcome To Beautiful World"

Answer 4

You can use replace with a regular expression :

var str = "Welcome\n\tTo\n\nBeautiful\t\t\t\nWorld";
alert($.trim(str.replace(/[\t\n]+/g, ' ')));
