How do I trim a string in javascript?

I have below string which comes from ajax response

"\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\r\n\tERROR: Profile : NOT SUCCESS\nCODE        : 2\nCATEGORY    : TECHNICAL\nSEVERITY    : null\nENVIRONMENT : DEV\nAPPLICATION : DEV\nDESCRIPTION : Profile: INVOCATION UNHANDLED EXCEPTION [null]\nDESCRIPTION : Profile: [ServiceAttribute]\nDESCRIPTION : Profile: Instance ID = 20130108124231841\n\r\n\r\n"

I am using below code to trim the string on both ends.

var text = originalRequest.responseText.replace(/^\s+|\s+$/g, ”);

However it’s removing \n in between message which is coming from ajax response.
What i would like to have in the end is

"ERROR: Profile : NOT SUCCESS
CODE        : 2
CATEGORY    : TECHNICAL
SEVERITY    : null
ENVIRONMENT : DEV
APPLICATION : DEV
DESCRIPTION : Profile: INVOCATION UNHANDLED EXCEPTION [null]
DESCRIPTION : Profile: [ServiceAttribute]
DESCRIPTION : Profile: Instance ID = 20130108124231841"

how do i get this? Trying different ways from past 1 hour 🙁

Just use trim();:

var s = "\r\n\r\n\r\n\r\n\r\n\r\n\r\n\t\r\n\tERROR: Profile : NOT SUCCESS\nCODE        : 2\nCATEGORY    : TECHNICAL\nSEVERITY    : null\nENVIRONMENT : DEV\nAPPLICATION : DEV\nDESCRIPTION : Profile: INVOCATION UNHANDLED EXCEPTION [null]\nDESCRIPTION : Profile: [ServiceAttribute]\nDESCRIPTION : Profile: Instance ID = 20130108124231841\n\r\n\r\n";
console.log(s.trim());

"ERROR: Profile : NOT SUCCESS
CODE        : 2
CATEGORY    : TECHNICAL
SEVERITY    : null
ENVIRONMENT : DEV
APPLICATION : DEV
DESCRIPTION : Profile: INVOCATION UNHANDLED EXCEPTION [null]
DESCRIPTION : Profile: [ServiceAttribute]
DESCRIPTION : Profile: Instance ID = 20130108124231841"

If trim()‘s not available (IE 8-), try this polyfill:

if(!String.prototype.trim) {
    String.prototype.trim = function () { 
        return this.replace(/^[\s\uFEFF]+|[\s\uFEFF]+$/g,'');
    });
}
