js Implementation of Text Truncation Function

先前用jq做了一个文字截断功能，但是不用jq的项目要实现此功能还要引如jq显得过于麻烦。这里写了一个js的文字截断功能。直接上代码。

JS:}　
var limit=[];
    var Text=[];
    var Pox=document.getElementsByTagName('*);
    for(var i=0;i<Pox.length;i++{
     if(Pox[i].getAttribute("limit")){
      limit[i]=Pox[i].getAttribute("limit");
      Text[i]=Pox[i].innerHTML;
      if(limit[i]<Text[i].length){
       Pox[i].innerHTML=Text[i].substring(0,limit[i]);+"...";
      }
     }
    } 
Here we use getElementsByTagName to get all nodes, traverse them, and filter nodes containing the custom attribute 'limit', then get the value of the custom attribute 'limit' of each node, put it into the limit array, put the text of each node into the Text array, compare the value to be truncated with the text length, and perform truncation.　


All JS, here written to be called automatically:
<script type="text/javascript">
 window.onload=function(){
  (function limit(){
   var limit=[];
    var Text=[];
    var Pox=document.getElementsByTagName('*);
    for(var i=0;i<Pox.length;i++{
     if(Pox[i].getAttribute("limit")){
      limit[i]=Pox[i].getAttribute("limit");
      Text[i]=Pox[i].innerHTML;
      if(limit[i]<Text[i].length){
      Pox[i].innerHTML=Text[i].substring(0,limit[i]);+"...";
      }
     }
    } 
   }());
   }
</script>
