Many time we are displaying text in javascript in the limit area where we want to break the string into multiple line. Recently I got requirement, so I created this function which helps to solve the problem

/*

*  param
03
*  d string to be splited in multiple line
04
*  l length where to break
05
*/

function splitmultiline(d, l){
07
	var df = ""
08
	var dl = 0 
09
	if(d!=undefined){
10
		var dlist = d.split(" ");
11
		for(i = 0; i < dlist.length; i++){
12
			dl +=dlist[i].length 
13
			if(i!=0)
14
				df+=" "
15
			if(dl>=l){
16
				df+="<br>"
17
				l +=l;
18
			}
19
			df+=dlist[i];
20
		}	
21
	}
22
	return df;

}
