Using js to solve the problem that numbers cannot wrap _ javascript skills

When a string of numbers, many browsers cannot automatically wrap the line, so it can be implemented using js. The Code is as follows:

Function toBreakWord (intLen, id ){
Var obj = document. getElementById (id );
Var strContent = obj. innerHTML;
Var strTemp = "";
While (strContent. length> intLen ){
StrTemp + = strContent. substr (0, intLen) +"
";
StrContent = strContent. substr (intLen, strContent. length );}
StrTemp + = strContent; obj. innerHTML = strTemp;
}

. Br {word-break: break-all; word-warp: break-word; background-color: # eee ;}
