JavaScript insert new line to any space in the middle of string -

i insert 1 new line character in middle of string:

for (var i=0; i<labels.length; i++){       if (labels[i].length > 30) {                //the split occur here        } } 

is there js function this?

any ideas?

edit

to replace spaces in string new line:

string.replace(/ /g, '\n');

/ /g refers global replace of spaces found.

say string follows:

var string = 'the quick brown fox jumps on lazy dog';

you need find length of string, middle point, , nearest space middle:

var length = string.length; var middle = math.round(length / 2); var spacenearmiddle = string.indexof(' ', middle); var string1 = string.substring(0, spacenearmiddle); var string2 = string.substring(spacenearmiddle + 1, length); 

the result of string1 , string2 "the quick brown fox" , "jumps on lazy dog".
