超出字数隐藏

早上来了,突然要我弄个超过多少字就隐藏,网上找了下,觉的都不是很合适,没办法自己写了个,扔上来备份,嘿嘿!~

这是一个链子,超过十个字我没了,嘿嘿!~

<script type="text/javascript">
function hideNum(thisId,showLeng){
 var nowId = document.getElementById(thisId);
 var nowLeng = nowId.innerHTML.length;
 if(nowLeng > showLeng){
  var nowWord = nowId.innerHTML.substr(0,showLeng)+'...';
  nowId.innerHTML = nowWord;
 }
}
</script>
<div id="test">超过十个字我没了!~</div>
<script>
 hideNum("test",10)
</script>
