<style type=”text/css”>

<!&ndash;

div {

width:300px;

word-wrap:break-word;

border:1px solid red;

}

&ndash;>

</style>

<div id=”ff”>aaaaaaaaaaaaaaaaaaaaaaaaaaaa＜/div>

<scrīpt type=”text/javascrīpt”>

function toBreakWord(el, intLen){

var ōbj=document.getElementById(el);

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;

}

if(document.getElementById && !document.all) toBreakWord(“ff”, 37);

</scrīpt>
