function returnLine(lines, str)
{
    var i, lines = lines.split("\n");

    for(i=0; i<lines.length; i++)
    {
        if(lines[i].indexOf(str) !== -1)
        {
            return lines[i];
        }
    }

    return '';
}

To use:

returnLine("this is test sample msg \n this is second line \n ", "sample");

var line = "sample text", var str = "sample";
if(line.indexOf(sample) > 0){
//do something
}else{
//do something else
}

var str = "this is test sample msg \n this is second line \n third samples";
str.split("\n").filter(function(str) {
    return ~str.indexOf("sample")
});
//["this is test sample msg ", " third samples"]
