I have an HTML page that I generate from the data contained in a database. The database sometimes contains long strings that the browser can\'t break because the strings don\'t
It's easier to break up the long words from a text string, before you add them to the document.
It would also be nice to avoid orphans, where you have only one or two characters on the last line.
This method will insert spaces in every unspaced run of characters longer than n, splitting it so that there are at least min characters on the last line.
function breakwords(text, n, min){
var L= text.length;
n= n || 20;
min= min || 2;
while(L%n && L%n
//test
var n=30, min=5;
var txt= 'abcdefghijklmnopqrstuvwxyz0123456789 abcdefghijklmnopqrstuvwxyz012345678 abcdefghijklmnopqrstuvwxyz01234567 abcdefghijklmnopqrstuvwxyz0123456';
txt=txt.replace(/(\w{30,})/g,function(w){return breakwords(w,n,min)});
alert(txt.replace(/ +/g,'\n'))
/* returned value: (String)
abcdefghijklmnopqrstuvwxyz0123
456789
abcdefghijklmnopqrstuvwxyz0123
45678
abcdefghijklmnopqrstuvwxyz012
34567
abcdefghijklmnopqrstuvwxyz01
23456
